1,563,366 | 1,563,367 | How to properly do sliding on android? | <p>ALL,
I have the following "simple" question. ;-)
I have an application which has an image background loaded from the png file.
On top I have an Image View which I would like to rotate with my fingers.
I am using MotionEvent to catch the sliding but apparently it works when I slide my fingers on the background but not on the image view.</p>
<p>My guess is that the view cover the background and the events are not ending up on the place.</p>
<p>How to overcome this problem?</p>

<pre><code>struct {
<whatever-type-you-want> item ;
int nextitem;
}
</code></pre>
<p>Here inserting into the list, is doing a push_back() on the vector and giving
an appropriate value to next-item. </p>
<p>2) In which you
have a collection of structs all over RAM. Here insert is done with
the C++ operators <code>new</code> .</p>
<p>Is it correct to say, that the first method is more efficient since all the items are in consecutive locations in memory, because of which one might be able to grow the linked list
to a much larger size than the second method</p>
<p>In the second method, there might be memory fragmentation with huge linked lists because of which one might get a segmentation fault much earlier.</p>

3,043,778 | 3,043,779 | PHP - Looping inside a loop, maybe? | <p>I am currently using a foreach loop to display some radio buttons like so</p>
<pre><code><?php
foreach($roles as $role){

$output .= ' <label for="'.$role->key.'" style="text-transform: lowercase;">'.$role->name.'</label>';
$output .= '</div>';
}
</code></pre>
<p>?></p>
<p>So thats fairly straight forward .... The bit that i need to do next is confusing ... i need to take the $role->key and see if it matches an entry in another table, if so, echo 'checked="checked"' on the radio button.</p>
<p>It will need to be matched by the $role->key and also the $userid.</p>
<p>Any help would be great.</p>

1,274,995 | 1,274,996 | TOO MANY if (obj is thisObj) statements | <p>I currently have method which is trying to find out what the obj is it recieved. It knows is on a certain interface, for example IService but I have code which looks at it and tries to tell me is it is for example Service1 or Service2.
I currently a lot of if(obj is thisObj) style statements, what would be the best solution to make this code pretty?</p>
<p>here is a sample of what exactly I have:</p>
<pre><code> public void DoSomething(IService service)
{
if (service is Service1)
{
//DO something
}
if (service is Service2)
{
//DO something else
}
}
</code></pre>
<p>now having two isnt too much of a bad thing, but I am looking at having probably 20+ of these which just becomes awful to use.</p>
<p>Any ideas?</p>
<hr>
<p>ok further details I think are needed and here they are:</p>
<p>prior to this method I have another method which is recieving a xml doc, which it them deserializes into the interface IService, so we have something like this:</p>
<pre><code> private static void Method(InnerXml)
{
var messageObj = (IServiceTask)XmlSerialization.Deserialize(typeof(IServiceTask), InnerXml);
var service = GetService(messageObj);
service.PerformTask(xmlDoc);
}
private static IService GetService(IServiceTask messageObj)
{
var service = new IService ();
if (messageObj is Task1)
{
service = (SomeService)messageObj;
}
if (messageObj is Task2)
{
service = (SomeOtherService)messageObj;
}
return service ;
}
</code></pre>
<p>Hopefully that makes it a bit clearer.</p>
