<pre><code> TextView text = new TextView(this);

<p>Now i want to search the list, Find all string elements with animal in them and add one to their number. So in the end of my query the list would look like:</p>
<pre><code>Cat, Animal, 3

Luke, Human, 1
Owl, Animal, 1

<p>How can i achieve this functionality? I was thinking of using a LINQ query to get all the entries that contain animal and then getting the index of each element in the list, getting all the tokens in each element by using a comma split, parsing the third token into an integer, incrementing by one and rewriting the element at the previously saved index to update the count. This is probably the least efficient method so can anyone suggest a fast, short and sweet solution to this?</p>

What I can't seem to understand is, what is the "s" in both_ends(s): doing?</p>
<pre><code># B. both_ends
# Given a string s, return a string made of the first 2
# and the last 2 chars of the original string,
# so 'spring' yields 'spng'. However, if the string length
# is less than 2, return instead the empty string.
def both_ends(s):
# +++your code here+++
# LAB(begin solution)
if len(s) < 2:
return ''
first2 = s[0:2]
last2 = s[-2:]
return first2 + last2
</code></pre>
<p>At the bottom of strings1.py there are some functions:</p>
<pre><code>def main()
print 'both_ends'
test(both_ends('spring'), 'spng')
if __name__ == '__main__':
main()
</code></pre>
<p>So how does the program know to substitute "spring" for (s) or is that not what it's doing? I can post the entire file if need be. It's only 140 lines.</p>

3,241,351 | 3,241,352 | Update Panel and AJAX Timer - Removing all controls on each Tick event | <p>I have an ASP.NET UpdatePanel Triggered to refresh based on the Tick event of a Timer.</p>
<p>The page parses a custom XML file and inserts UserControls (containing GridViews) on the fly. This is executed from the <code>Page_Load</code> method.</p>
<pre><code>if(!Page.IsPostBack)
parseXmlFile();
</code></pre>
<p>The first time the page loads, all the controls are displayed as expected. The problem is that the first time the timer <code>Tick</code> event is fired, all the UserControls disappear.</p>
<p>In the <code>Tick</code> event I call a custom method <code>RefreshData()</code> which in turn rebinds the data to the GridView via an SqlDataSource.</p>
<pre><code> public void RefreshData() {
GridView1.DataBind();
...
</code></pre>
<p>Maybe I don't understand how AJAX works in ASP.NET. </p>
<p>I only want to parse the XML file once (which creates all the UserControls in the page). From this point I just want to refresh the data contained in the GridView and change the Visibility state of the GridView.</p>

It would be our own hardware, never leave the building, and run any program we create. <strong>Why?</strong> The Android has built in battery backup, theft detection (GPS), and an elegant touch screen, and a familiar programming interface.</p>
<p><strong>What I want:</strong></p>
<ol>
<li><p>Can I require that no matter what is pressed on the screen, the user never leaves my app?</p>
<p>Are there <strong>instructions</strong> to do this, is it <strong>officially supported</strong>, <strong>or would I have to start hacking away</strong>? (using a system-level interface, removing voice activation (when a user holds down the Search button), disable auto updates, etc)</p>
<p>Ideally, I want to just write a single app that replaces the whole interface, and I want a way to hook the app in, without a bunch of extra work (rooting the phone and manually removing built specific built-in apps).</p></li>
<li><p>I would also want to lock the USB into a "Charge-only" mode, to prevent mounting of the file system without my app's approval. I am not concerned about a really determined guy who opens up the device and mounts the internal storage unit's filesystem.</p></li>
<li><p>In the event of a crash, I would like to have a second app that decides whether or not to restart the first app.</p></li>
</ol>
<p>Obviously, I don't want the phone to become unusable, even if it is just spare hardware.</p>

1,128,726 | 1,128,727 | Check if one letter is in a string(word), and what posistion it is at? | <p>I have one method with one letter(string\char?) as argument and one word active at a time. I would like to see if this one letter, is in the word which is active at the time.</p>
<p>That could probably have been explained better. Maybe code will do the trick:</p>
<pre><code>public void checkLetter(String letter){
for(int i = 0; i<activeWord.length(); i++){
if(letter.equals(activeWord.[i])){
// Run a method which gives the user a correct letter pushed.
}
else {
String failed = "Could not find the letter in the active word.";
// Run a method which gives the user one wrong letter pushed.
}
}
}
</code></pre>
<p>So, this is going to be a hangman game for android i'm making for fun. Right now i have images as letters. When the letter(image) is pressed, this method runs, and the letter pushed will be the argument.</p>
<p>Does anyone have any good ideas how i can find out if the letter is in the word, and which posistion it is in?</p>
<p>I would love some help :)</p>
<p>EDIT: Btw, the current code returns int every time ofc, cause the [i] is an int. This is where im strugling to get the code to return a string. Do i have to split the word up into letter before i can equal them to another string?
Thanks.</p>

<p>I would think that the problem is somewhere in the code that gets the focused view, but ive tried findFocus and getCurrentFocus, and both return the same thing. Here is the code, thanks!</p>

4,558,920 | 4,558,921 | jQuery: Append and prepend unclosed HTML to an element | <p>In an application I'm creating, I am allowing the end-users to add a "Text Formatting" prefix and suffix to a jQuery countdown.<br>
The elements for the countdown are fetched with AJAX, and inserted to DOM with jQ. </p>
<p>An example for these two fields can be:<br>
Prefix: <code><span style="color:blue"></code><br>
Suffix: <code></span></code></p>
<p>What I need to do then is wrap all the code needed for the countdown between these two.<br>
But when I try to add them, all jQuery methods I've tried (append & prepend) and PrototypeJS' <code>Element.insert()</code> will close any open tags in the prefix, rendering the suffix useless. </p>
<p>I even tried the following: </p>
<pre><code>$( this ).parent().html( data['prefix'] + $( this ).parent().html() + data['suffix'] );
</code></pre>
<p>This resulted in the element being removed from the DOM tree. Also tried to locally store the innerHTML and fiddle with it before pushing it back to <code>.html()</code>. </p>
<p>And I can not combine those two fields together, and use <code>.wrap()</code> on it, as either of them can be a completely perfect HTML string. </p>
<pre><code><span class='tag'>This is a tag</span>
</code></pre>
<p>If I tried to use <code>.wrap()</code> on that, I assume the rest of my code would end up inside that.</p>
