how to read an MP3 file for audio processing in Delphi? : <p>When I want to process an audio in a byte level, I always convert it in .wav format and then do my processing. For example in my last project, I was trying to generate a kind of special waveform image of my audio file to use it in a video clip. Then I converted my .mp3 file to .wav file (mono, 8 bit, 6KHz) using an online tool and then I maked my waveform picture programmatically.</p>
<p>Now I want to be able to do my processing on an .mp3 file directly without conversion, like the code below:</p>
<pre><code>aFrom := 60000; // From 00:01:00.000
aLength := 20000; // 20 Second
aChannels := 1; // mono
aBitsPerChannel := 8;
aFreq := 6000;
aBufSize := Open_MP3_As('d:\Until The Last Moment.mp3',
aBuffer, aFrom, aLength,
aChannels, aBitsPerChannel, aFreq);
for i := 0 to aBufSize - 1 do
begin
// Processing aBuffer[i]
end;
</code></pre>
<p>this is just an example of showing what in my mind is. As you can see, the metadata and the details of the .mp3 file is not important for me.</p>
<p>This would be very useful because I can embed this ability to my audio tools and let the user use my tools very faster and easier. I know that it could be a very complicated code because at the first time, the .mp3 file must be converted to .wav file (with the specific given parameters), then it must remove the header, slice it and put it in the aBuffer and return the amount of samples in aBuffer.</p>

TensorFlow: How can I evaluate a validation data queue multiple times during training? : <h2>tl;dr</h2>
<p>How can I evaluate a validation set after every K training iterations, using separate queues for training and validation data, without resorting to separate <code>tf.Sessions</code> in multiple processes? There doesn't seem to be a clean way to achieve this, given my particular problem, and my current workaround (which I thought would work) gives me undefined behavior. Help!</p>
<h2>The whole story</h2>
<p>I want to evaluate a validation set every K training iterations, and I cannot figure out how to implement this properly in TensorFlow. This should be one of the most common operations, yet it feels that TensorFlow's API/architecture is working against me here or is at least making things unnecessarily difficult.</p>
<p>My assumptions are:</p>
<ul>
<li>[A1] The multi-process model for training/validation as described here <a href="https://www.tensorflow.org/how_tos/reading_data/#multiple_input_pipelines" rel="noreferrer">https://www.tensorflow.org/how_tos/reading_data/#multiple_input_pipelines</a> is not applicable to my problem, as I have to assume there is not enough GPU memory available to load the variables twice.</li>
<li>[A2] I want to evaluate on the validation set every K training iterations.</li>
<li>[A3] Both training and validation data cannot be simply read from disk, but are generated on-the-fly. This makes it impossible to reliably pre-compute the size of the validation set in advance.</li>
<li>[A4] The validation set is too large to pre-compute and store onto disk.</li>
<li>[A5] The effective validation set size is not necessarily a multiple of the batch size.</li>
</ul>
<p>The training input pipeline is set up as follows:</p>
<ul>
<li>A <code>tf.train.slice_input_producer()</code> generates a (shuffled) list of filenames, each referring to raw input data.</li>
<li>A custom data generation function generates a variable number of training exemplars/labels from each chunk of raw input data.</li>
<li>The generated training exemplars/labels are queued via <code>tf.train.shuffle_batch()</code> before being fed into the network.</li>
</ul>
<p>Due to [A3], [A4], [A5], the validation input pipeline is set up in an almost identical way, except that the final input queue is generated via <code>tf.train.batch()</code>, since shuffling is not desirable. Due to the above assumptions, a feed_dict based approach is also infeasible, and also seemingly incompatible with using a higher level function such as <code>tf.train.batch</code>.</p>
<p>However, a straightforward implementation using two different sets of queues for training and validation does not work. As far as I understand, I have two options:</p>
<ul>
<li><p>[B1] Set the <code>num_epochs</code> argument of the validation <code>tf.train.slice_input_producer</code> to <code>None</code>.</p>
<p>In this case, the validation set is cycled through endlessly, but I would need to know the size of the validation set in advance to explicitly limit the number of batches to evaluate per run through the validation set. Furthermore, if the validation set size is not divisible by the batch size, I will always pull a bit more in the last batch. As this would shift the order of evaluation of the validation data each time, this is not acceptable.</p></li>
<li><p>[B2] Set the <code>num_epochs</code> argument of the validation <code>tf.train.slice_input_producer</code> to <code>1</code>, and additionally set the <code>allow_smaller_final_batch</code> argument of the <code>tf.train.batch</code> function to <code>True</code>.</p>
<p>In this case, the validation set is cycled through exactly once, after which the respective queue is closed forever. By default, this will make evaluating the validation set two or more times impossible. Since I do not know of a good way to reopen a queue in TensorFlow, I need to work around this limitation. </p></li>
</ul>
<p>Due to the greater limitations of option [B1], I chose to work around the issues of option [B2] instead. The (pseudo-)code outlining my current approach is as follows:</p>
<p>The training loop should be fairly canonical. Every K iterations, a function to evaluate the validation set is called.
Note that I only start the queues that have a name starting with "train_"; these is the queue set up for collecting generated training data. In order to do this, I created two helper functions, <code>get_queues_by_name</code> and <code>start_queue_runners</code>. </p>
<pre><code>def train_loop(train_ops, vali_ops, ...):
with tf.Session() as sess:
coord = tf.train.Coordinator()
sess.run([tf.initialize_all_variables(), tf.initialize_local_variables()])
load_latest_snapshot(sess, loader, snapshot_file)
# Launch the queue runners
queues = get_queues_by_name("train")
threads = start_queue_runners(sess, coord, queues)
try:
for step in range(start_iteration, num_train_iterations):
# Runs the session on validation set
if step % K == 0:
validation_results = run_validation(vali_ops, snapshot_file)
# TRAINING:
# ...
except Exception as e:
coord.request_stop(e)
finally:
coord.request_stop()
coord.join(threads)
</code></pre>
<p>The helper functions look like this:</p>
<pre><code>def get_queues_by_name(name):
"""Retrieves all queues that contain the string given by 'name'"""
all_queues = tf.get_collection(tf.GraphKeys.QUEUE_RUNNERS)
return [q for q in all_queues if name in q.name]
def start_queue_runners(session, coordinator, queues):
"""Similar to tf.train.start_queue_runners but now accepts a list of queues instead of a graph collection"""
with session.graph.as_default():
threads = []
for queue in queues:
log("Queue", "Starting queue '%s'" % queue.name, level=2)
threads.extend(queue.create_threads(session, coordinator, daemon=True, start=True))
return threads
</code></pre>
<p>In the <code>run_validation</code> function, my chosen workaround against the issue of a closed queue is to create a new <code>tf.Session</code>. I also only start the threads associated with the queue collecting validation set data.</p>
<pre><code>def run_validation(ops, snapshot_file): # Called inside train_loop()
results = None
loader = tf.train.Saver()
with tf.Session() as sess:
coord = tf.train.Coordinator()
sess.run([tf.initialize_local_variables()])
load_latest_snapshot(sess, loader, snapshot_file)
# Launch the queue runners
queues = get_queues_by_name("eval")
threads = start_queue_runners(sess, coord, queues)
# Performs the inference in batches
try:
# Evaluate validation set:
results = eval_in_batches(ops, sess)
except Exception as e:
coord.request_stop(e)
finally:
coord.request_stop()
coord.join(threads)
return results
</code></pre>
<p>I do not know whether creating a new <code>tf.Session</code> here is a good idea, but it seems like the only way to accomplish restarting the validation queue. Ideally, I also wouldn't want to re-load the model snapshot, as this seems conceptually unnecessary.</p>
<p>The issue with this code is that I see erratic/undefined behavior during running, such as NaN's or Inf's appearing inside the network during validation set evaluation. This seems to occur predominantly when the validation set queue is being filled at the same time as the training set queue is still being filled (since the training queue is open during validation set evaluation). For example, this very often happens if I evaluate the validation set at iteration 0 (when both queues still need to be filled). It almost seems as if the training/validation queues share some global state, although they are running in a different session.</p>
<p>Can someone explain why this is happening, and how I can solve this more cleanly while taking my above assumptions [A1]-[A5] into account?</p>

MVC5 Multiple types were found that match the controller named 'Home' : <p>I was trying to clone a project called IdentitySample but I wanted to rename it to RecreationalServicesTicketingSystem. I've followed a few guides as to how to rename everything but it seems the application is still picking up
<code>IdentitySample.Controllers.HomeController</code> . I've tried using the find function to look through codes to see if IdentitySample was still in our application but I've found none.</p>
<p>Can give me a few pointers as too where I might have missed renaming the solution?</p>
<blockquote>
<p>Multiple types were found that match the controller named 'Home'. This
can happen if the route that services this request
('{controller}/{action}/{id}') does not specify namespaces to search
for a controller that matches the request. If this is the case,
register this route by calling an overload of the 'MapRoute' method
that takes a 'namespaces' parameter.</p>
<p>The request for 'Home' has found the following matching controllers:
RecreationalServicesTicketingSystem.Controllers.HomeController

What is a fast and proper way to refresh/update plots in Bokeh (0.11) server app? : <p>I have a bokeh (v0.11) serve app that produces a scatter plot using (x,y) coordinates from a data frame. I want to add interactions such that when a user either selects points on the plot or enters the name of comma-separated points in the text box (ie. "p55, p1234"), then those points will turn red on the scatter plot. </p>
<p>I have found one way to accomplish this (Strategy #3, below) but it is terribly slow for large dataframes. I would think there is a better method. Can anyone help me out? Am I missing some obvious function call?</p>
<ul>
<li><strong>Strategy 1</strong> (<1ms for 100 points) drills into the ColumnDataSource data for the exist plot and attempts to change the selected points. </li>
<li><strong>Strategy 2</strong> (~70ms per 100 points) overwrites the plot's existing ColumnDataSource with a newly created ColumnDataSource. </li>
<li><strong>Strategy 3</strong> (~400ms per 100 points) is Strategy 2 and then it re-creates
the figure.</li>
</ul>
<p>Code is deposited on pastebin: <a href="http://pastebin.com/JvQ1UpzY">http://pastebin.com/JvQ1UpzY</a> Most relevant portion is copied below.</p>
<pre><code>def refresh_graph(self, selected_points=None, old_idxs=None, new_idxs=None):
# Strategy 1: Cherry pick current plot's source.
# Compute time for 100 points: < 1ms.
if self.strategy == 1:
t1 = datetime.now()
for idx in old_idxs:
self.graph_plot.data_source.data['color'][idx] = 'steelblue'
for idx in new_idxs:
self.graph_plot.data_source.data['color'][idx] = 'red'
print('Strategy #1 completed in {}'.format(datetime.now() - t1))
else:
t3 = datetime.now()
self.coords['color'] = 'steelblue'
self.coords.loc[selected_points, 'color'] = 'red'
new_source = bkmodels.ColumnDataSource(self.coords)
self.graph_plot = self.graph_fig.scatter('x', 'y', source=new_source, color='color', alpha=0.6)
print('Strategy #3 completed in {}'.format(datetime.now() - t3))
return
</code></pre>
<p>Ideally, I would like to be able to use <strong>Strategy #1</strong>, but it does not seem to allow the points to refresh within the client browser.</p>
<p>Thanks for any help!</p>
<p>FYI: I am using RHEL 6.X</p>

<pre><code> input: H23ey Th2e3re St01ack O34verflow
output: H3ey There St1ack O4verflow
</code></pre>
<p>I can do it another way by using a new string, looping through the existing one and adding only what isalpha or isspace, but it seems messier.</p>
<p><strong>code:</strong></p>
<pre><code>string digalpha {};
cout << "Enter string containing both numbers and letters: ";
getline(cin, digalpha);
for (size_t i {}; i < digalpha.size(); i++)
if (isdigit(digalpha.at(i)))
digalpha.erase(i,1);
cout << digalpha << endl;
cout << endl;
return 0;

Finding Day for given Date : I have worked with a simple C program to find the Day for Given Date. For it I have wrote lot of lines to calculate the day and month and to find the kind of the given year. While Surfing I came to know about a single line code to find the day for given date. The code is as below
( d += m < 3 ? y --: y- 2, 23 * m / 9 + d + 4 + y / 4 - y / 100 + y / 400) % 7 ;
// 0 - Sunday, 6 - saturday
It gave correct answer for all inputs, but I couldn't understand the values used in this expression.
1. Why the sum of day and month is checked for less than 3.
2. Why the year is reduced by one and the condition fails it decreases the year by 2.
3. Why the number 3, 23 and 9 are used in this expression.
Please let me know what is the logic behind this, I'm tried of seacrching the solutions.

I'm just beginning to learn C: Can someone explain what the pointers and typecasting are doing in this code? : <p>//Beginning of a Function:</p>
<pre><code>char *encrypt(char *string, size_t length) {
}

<p>I am beginning a simple encryption function, and I'm wondering what exactly the above code is carrying out? I am assuming I'm initializing an encrypt function as char pointer, with a memory destination 'string' and size of 'length'</p>
<p>Am I correct?</p>

Incorrect path file reference to packages when sharing solution between mac and windows : <p>I have solution/flutter app running on <strong>windows</strong> fine. Within the .packages file vscode is referencing the package via </p>

<p>I have the flutter sdk installed c:\flutter directory on windows.</p>
<p>I copied this solution via dropbox to the <strong>mac</strong> and when running </p>
<p>"Warning! This package referenced a Flutter repository via the .packages file that is no longer available". </p>
<p>In an effort to isolate/locate the problem, I created a new Flutter project on the mac and found that the .packages file referenced packages via </p>
<pre><code>analyzer:file:///flutter/.pub-cache/hosted/pub.dartlang.org/analyzer-0.31.2-alpha.2/lib/

<p><strong>Notice</strong> the different paths used on both systems.</p>
<p>I suspect I can search/replace the references file:///c:/flutter to file:///flutter and it should work but I would like to avoid always manually swapping out locations. Is there an easier approach when sharing solutions across mac and windows? </p>

npm run does nothing : <p>I've been working with Node.js/npm for a while, but I never used npm scripts. I was quite surprised to find that I can't get them to work at all on my Windows/Cygwin system. With a package.json like this ...</p>

"name": "demo",
"scripts": {
"env": "env",
"hello": "echo Hello!",
"crap": "I am complete nonsense."
}
}
</code></pre>
<p>... all three npm run commands do nothing. <code>npm run crap</code> executes and returns immediately with an OK status (I tested with the -dd parameter); <code>npm run doesntexist</code> throws the expected error. Testing without Cygwin on the regular Windows shell made no difference.</p>

Javascript or Jquery sum of highest 5 values : Please do not mark this question as **DUPLICATE**. I am really facing the problem.
I have an array of 6 values where 6th value is optional (i.e. if user does not input 6th value, the first 5 values will be calculated). I want to sum highest 5 values of them.
My Javascript Code:
function calculate_merit_point(){
var s1 = eval(document.getElementById('sub_no1').value);
var s2 = eval(document.getElementById('sub_no2').value);
var s3 = eval(document.getElementById('sub_no3').value);
var s4 = eval(document.getElementById('sub_no4').value);
var s5 = eval(document.getElementById('sub_no5').value);
var s6 = eval(document.getElementById('sub_no6').value);
var vals = [s1,s2,s3,s4,s5,s6];
function arraySum(arr) {
if (!arr) {
return false;
} else {
var sum = 0;
for (var i = 0, len = arr.length; i < len; i++) {
sum += arr[i];
}
return sum;
}
}
sum = arraySum(vals.sort(function(a, b) {
return b - a;
}).slice(0, 5));
if(isNaN(tt)){
$('#agr').text('0');
} else {
$('#agr').text(sum);
}
}
Now suppose
s1 = 30
s2 = 31
s3 = 32
s4 = 33
s5 = 34
s6 = 35
It should be `31+32+33+34+35 = 165`. but it is displaying the value 162.
As per my requirement (6th value optional), if I do not give any value to `s6`, it is displaying the value **228**.
I have tried [This][1], but if I do not give the 6th (optional) value, it is showing the value `0`. If I give the value 35 in s6, it is showing sum value 233.
**What should I do ?**

Add foreign key to table after migration has been run in laravel : I have the following migration in my laravel migrations folder that i have already run:
<?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateAdminTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up() {
Schema::create('Admin' , function($table){
$table->increments('id');
$table->mediumText('title');
$table->text('blog_content');
$table->char('tag' , 15);
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down() {
Schema::drop('Admin');
}
}
The above migration is for my `admin` table, what i would really like to do is add a foreign key in my `admin` table that is associated with my `tags` table. something like:
$table->foreign('tag')->references('tag')->on('tags');
How do i do this now that i have already run my migration ??

Msg 8152, Level 16, State 2, Line 1. Finding wich columns will be truncated : It's been asked hundred times, but I'm on a predicament, I was delegated to mantain a table from an external DB with the data I handle on my DB, what I'm faced now it's getting data from my DB to that table, the problem being the lengh of the values I have (data it's 90% equivalent at worst, but I also handle more precise data) and getting the classic `Msg 8152, Level 16, State 2, Line 1 Los datos de cadena o binarios se truncarían.`. I know I could check each column and comparing total lengh but we are talking about 130 columns and more than 6 joins on my procedure.
I did `SET ANSI_WARNINGS OFF` and found about 10 columns conflicting with the table (data shows clearly truncated values), but I still need to compare 120 columns with abount 4k rows.
With that being said is there a easier/less manual way to detect wich columns are raising errors? | 0debug |

SQLSTATE[HY093]: All parameters are filled properly and the syntax is right, so what's wrong? : I am getting the following error and I can't figure out just why:
`SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens in`
Here's the code:
$transactions_sql = "INSERT INTO transactions (usr, service, txn_id, orig_amount, currency, date, description, fee_amt,
fee_currency, fee_descr, fee_type, net_amt, status) VALUES ";
$transactions_sql_data = array_fill(0, count($transactions) - 1, "(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)");
$transactions_sql .= implode(",", $transactions_sql_data);
$stmt = $conn->prepare($transactions_sql);
foreach ($transactions["data"] as $tr) {
$stmt->bindValue(1, $id, PDO::PARAM_INT);
$stmt->bindValue(2, tr["service"], PDO::PARAM_STR);
$stmt->bindValue(3, $tr["id"], PDO::PARAM_INT);
$stmt->bindValue(4, $tr["amount"], PDO::PARAM_INT);
$stmt->bindValue(5, $tr["currency"], PDO::PARAM_STR);
$stmt->bindValue(6, $tr["created"], PDO::PARAM_STR);
$stmt->bindValue(7, $tr["description"], PDO::PARAM_STR);
$stmt->bindValue(8, $tr["fee_details"][0]["amount"], PDO::PARAM_INT);
$stmt->bindValue(9, $tr["fee_details"][0]["currency"], PDO::PARAM_STR);
$stmt->bindValue(10, $tr["fee_details"][0]["description"], PDO::PARAM_STR);
$stmt->bindValue(11, $tr["fee_details"][0]["type"], PDO::PARAM_STR);
$stmt->bindValue(12, $tr["net"], PDO::PARAM_INT);
$stmt->bindValue(13, $tr["status"], PDO::PARAM_STR);
}
$stmt->execute();
Doing `var_dump($transactions_sql)` prints `"INSERT INTO balance_transactions (usr, service, txn_id, orig_amount, currency, date, description, fee_amt, fee_currency, fee_descr, fee_type, net_amt, status) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?),(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?),(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)"`, which is correct (in terms of number of question marks - there will only be three arrays inside the `$tr` array).
So what's wrong here?

Prime numbers with range up to 10^12 : I'm testing some algorithm in console apllication.

continue;
}
if (isPrime(i))

counter++;
}

Console.WriteLine(counter);
TimeSpan duration = DateTime.Now - start;
Console.WriteLine(duration.TotalMilliseconds);

if (number == 2) return true;
for (int i = 2; i <= Math.Ceiling(Math.Sqrt(number)); ++i)
{
if (number % i == 0) return false;
}
return true;
}
As you can see in for loop, first I examine whether number is i > 2 && i%2==0 since in that case number isn't prime.
Is there any more tricks to avoid such numbers not to get to the isPrime method or what's the best solution to avoid timeouts? | 0debug |

Although I have specified where gmp, mpfr, and mpc are located. And I have the latest versions of them.
Is there anything I am missing? Please answer as soon as possible :) | 0debug |
iOS URLRequest POST Failing Swift : <p>I am currently trying to make a POST request on the iOS platform with a JSON body. My request works in cURL, but I cannot get it to work in iOS; the request times out. Here is my swift code:</p>
<pre><code> class func createNewChannel(name: String, priv: String, channelKey: String, handle: String, password: String, auth: String) {
let baseURL = "http://10.0.0.220:3000/"
let dict = ["name": name, "private": priv, "channelKey": channelKey, "handle": handle, "password": password, "auth": auth] as [String : Any]
let jsonData = JSON(dict)
do {
let post = try jsonData.rawData()
let postLength = String(post.count)
let url = URL(string: "\(baseURL)channel/createChannel")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = post as Data
request.setValue(postLength, forHTTPHeaderField: "Content-Length")
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.setValue("application/json", forHTTPHeaderField: "Accept")
let session = URLSession.shared
let task = session.dataTask(with: request, completionHandler: { (data, response, error) in
if error == nil {
do {
let json = try JSON(data: data!)
print(json)
}
catch {
print(error.localizedDescription)
}
}
else {
print(error!)
}
})
task.resume()
}
catch {
print(error.localizedDescription)
}
}
</code></pre>
<p>When I call this function, the request does not work...I am sure I am using the right url because it works with a GET endpoint. Am I missing any headers? Please let me know if you see something wrong with the request.</p>

How to do lamda operations with stream? : As for now I am doing :
Map<Integer, Item> itemList = getItems(input);
Iterator<Item> ItemIterator = input.getItems().iterator();
List<Item> updatedItems = Lists.newLinkedList();
for (int i = MIN; i <= input.getInputReq().getList().size(); i++) {
Item item = itemList.get(i);
if (item != null) {
item.setFlag(false);
item.setId(getId());
updatedItems.add(item);
itemList.remove(i);
} else {
if (ItemIterator.hasNext()) {
updatedItems.add(ItemIterator.next());
}
}
}
Is there any efficient way I could do this with Streams and lambda in java8 ? | 0debug |

Run multiple android app instances like parallel space : <p>I want to know how parallel space
<a href="https://play.google.com/store/apps/details?id=com.lbe.parallel.intl&hl=en">https://play.google.com/store/apps/details?id=com.lbe.parallel.intl&hl=en</a> is working. It is an app for logging in with another facebook, whatsapp etc account. You can find the detailed description in the play store link.</p>
<p>I have looked at the folders that parallel space is creating using ES Explorer. They have created the following folder parallel_intl/0/</p>
<p>In this folder they have DCIM, Pictures etc folder. I logged in another whatsapp account using parallel space and they created the whatsapp folder at the following location parallel_intl/0/Whatsapp </p>
<p>Is it possible to achieve the same thing with Android For Work Container???</p>
<p>Are they some how creating a separate space where Whatsapp etc will run???</p>
<p>Kindly provide some guideline explaining how this can be achieved.</p>
<p>Thanks.</p>

android margins not working when dynamically inserting views : <p>I have a simple view:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/contact_selected"
android:layout_marginTop="10dp"
android:layout_marginEnd="5dp"
android:orientation="horizontal"
android:padding="3dp">
<TextView
android:id="@+id/txt_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Billy Bob"
/>
</LinearLayout>
</code></pre>
<p>When I statically copy the LinearLayout markup into my main activity layout, the margins are as expected. However, when I add the view into the main activity layout dynamically, the margins are ignored. Here's how I insert the view</p>
<pre><code>LayoutInflater inflater = (LayoutInflater)
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.test, null);
TextView txt_title = (TextView)view.findViewById(R.id.txt_title);
txt_title.setText("Dynamic #1");
llayout.addView(view, llayout.getChildCount()-1);
View view2 = inflater.inflate(R.layout.test, null);
txt_title = (TextView)view2.findViewById(R.id.txt_title);
txt_title.setText("Dynamic #2");
llayout.addView(view2, llayout.getChildCount()-1);
</code></pre>
<p>Here's what it looks like:</p>
<p><a href="https://i.stack.imgur.com/7si8I.png" rel="noreferrer"><img src="https://i.stack.imgur.com/7si8I.png" alt="enter image description here"></a></p>
<p>The container in the main layout is a LinearLayout, which is a child of a HorizontalScrollView. Any insight is appreciated.</p>

value.asJava

<p>I don't quite understand what's going on in the first piece of code. Searching for <strong><em>scala left arrow operator</em></strong> did't shed the light on this. Can't you explain it?</p>
