3,403,522 | 3,403,523 | Pointer to int array, passing and using it from another method | <p>I haven't cemented my learning of C++ arrays and have forgotten how to do this properly. I've done it with char array before but its not working as well for int array. </p>
<p>I declare a new blank int array:</p>
<pre><code>int myIntArray[10];
</code></pre>
<p>So this should be an array of nulls for the moment correct?</p>
<p>Then I assign a pointer to this array:</p>
<pre><code>int *pMyArray = myIntArray
</code></pre>
<p>Hopefully thats correct to there.</p>
<p>Then I pass this to another method elsewhere:</p>
<pre><code>anotherMethod(pMyArray)
</code></pre>
<p>where I want to assign this pointer to a local variable (this is where I'm really not sure):</p>
<pre><code>anotherMethod(int *pMyArray){
int myLocalArray[];
myLocalArray[0] = *pMyArray;
}
</code></pre>
<p>I'm not getting any compilation errors but I'm not sure this is right on a few fronts. Any and all help and advice appreciated with this.</p>
<p>Edit:</p>
<p>I should have said what I am trying to do.</p>
<p>Very simple really, I'd just like to modify a local array from another method. </p>
<p>So I have:</p>
<p>Method 1 would contain: </p>
<p>int myArray1[10] = {0};</p>
<p>Method 2 would be passed the pointer to myArray:</p>
<p>Then some code to modify the variables in the array myArray. </p>

3,991,930 | 3,991,931 | What MUST go inside onDestroy()? (if anything at all) | <p>Right so here I am obsessing over memory leaks, and quite frankly not understanding what could really lead to one (and yes I've read the usual links such as <a href="http://kohlerm.blogspot.co.uk/2009/02/memory-leaks-are-easy-to-find.html" rel="nofollow">http://kohlerm.blogspot.co.uk/2009/02/memory-leaks-are-easy-to-find.html</a>).</p>
<p>I've tried to create some on purpose, for example by leaving a PhoneStateListener subclass inside my activity and opened and closed it a bazillion time, can't see anything in DDMS heap or MAT out of the ordinary. Yet on SO I read over and over again that not only it needs to be deregistered onDestroy, but also onPause (http://stackoverflow.com/questions/4607344/phonestatelistener-isnt-finished)</p>
<p>Question: is there such a list?
Bonus question: is it true that a PhoneStateListener will create leaks unless it's deregistered onPause/onDestroy etc.</p>
<p><strong>UPDATE:</strong> I stand corrected. When re-spawning my app over and over again, even in singleinstance mode, the PhoneStateListener(s) it has registered are still alive after onDestroy was called, and start adding up. I'm currently working on an elegant way to kill them, and will post my results here.</p>
<p><strong>UPDATE2:</strong> The correct way to deregister the listener is:
instanceOfTelephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_NONE);
... according to the API</p>
<p><strong>UPDATE3:</strong> As promised linking this to a better phrased question: <a href="http://stackoverflow.com/a/4607435/821423">http://stackoverflow.com/a/4607435/821423</a></p>

1,166,204 | 1,166,205 | How to break an functional-style iteration? | <p>I'm experimenting with functional-style Javascript and have encountered an interesting situation. I have a foreach function that takes a collection and function object:</p>

Utils.foreach = function(collection, functor)
{
for (var i = 0; i < collection.length; i++)
{
functor(collection[i]);

<p>This is cool. However now I want to implement another function: </p>

Utils.has = function(collection, item)
{
Utils.foreach(collection, function(obj) {
if (item === obj) {
return true; // How to force a return from the foreach function?

});
return false;
};

<p>As you can see I can't implement the "has" function because my return statement doesn't break the iteration.</p>

1,934,240 | 1,934,241 | setContentView over and setting ImageView force close | <p>So basically the screen has a GridView with 9 images on it. When one of those images clicks I have it setContentView to open a layout of just an image view so it displays the chosen image. After they are done with that image they will click back and it gets rid of that contentView and displays the GridView again. The majority of that works except for it using the ImageView in the other contentView. </p>
<pre><code>public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setView();
setContentView(R.layout.wall);
GridView gridview = (GridView) findViewById(R.id.gridview);
gridview.setAdapter(new ImageAdapter(this));
gridview.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
pos = position;
displayWallpaper();
}
});
}
private void displayWallpaper(){
switch(pos){
case 0:
setContentView(R.layout.wallpaper);
viewing=true;
ImageView image1 = (ImageView)findViewById(R.id.display);
rotate(R.drawable.wallpaper1, image1);
break;
}
}
</code></pre>
<p>So the force close is happening at the ImageView line. And my guess is it isn't finding display, but display is in the wallpaper layout. Any ideas why it may be force closing. If you need more info let me know what and if you have a better way of doing what I am trying to make happen let me know. Thanks.</p>
<p>Also just tested it out. So far the force close still happens if rotate() is commented out and ImageView is there. If I comment both out it works fine (apart from displaying the image).</p>
