Android context menu not appearing

Question

My problem is just as it says in the description, the context menu is not appearing on a "touch and hold" from the user. I've got a feeling it could be where I placed registerForContextMenu.
Here's my MainActivity:

import java.util.ArrayList;
import android.app.ListActivity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.ContextMenu;
import android.view.ContextMenu.ContextMenuInfo;
import android.view.MenuInflater;
import android.view.View;
import android.widget.ListView;
public class MainActivity extends ListActivity {
private ArrayList<Sound> mSounds = null;
private SoundAdapter mAdapter = null;
static MediaPlayer mMediaPlayer = null;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
registerForContextMenu(getListView());
setContentView(R.layout.activity_main);
this.getListView().setSelector(R.drawable.selector);
//create a simple list
mSounds = new ArrayList<Sound>();
Sound s = new Sound();
s.setDescription("Anjels");
s.setSoundResourceId(R.raw.anjels);
mSounds.add(s);
s = new Sound();
s.setDescription("Aggro");
s.setSoundResourceId(R.raw.aggro);
mSounds.add(s);
s = new Sound();
s.setDescription("Basix");
s.setSoundResourceId(R.raw.basix);
mSounds.add(s);
s = new Sound();
s.setDescription("Bender");
s.setSoundResourceId(R.raw.bender);
mSounds.add(s);
mAdapter = new SoundAdapter(this, R.layout.list_row, mSounds);
setListAdapter(mAdapter);
}
@Override
public void onListItemClick(ListView parent, View v, int position, long id){
Sound s = (Sound) mSounds.get(position);
MediaPlayer mp = MediaPlayer.create(this, s.getSoundResourceId());
mp.start();

}
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.context_menu, menu);
  }
}

Target of actual device? Target is api "10" ICS but I'm running an SGS3mini on api "16" Jellybean — Jason Mills, Aug 06 '13 at 18:41

Try switching these two lines around

registerForContextMenu(getListView());
setContentView(R.layout.activity_main);

so it should be

setContentView(R.layout.activity_main);
registerForContextMenu(getListView());

Your feeling was correct. Your ListView is in your layout so you need to inflate it first before registering the View

Can I just ask, so I can learn from this, why does that make a such a difference which line comes first? – Jason Mills Aug 06 '13 at 18:42
As I said in my last sentence of the answer, your `Views` exist within your `layout` so its like they don't exist until the root `layout` has been inflated. Same reason that if you try to initialize a `View` before calling `setContentView()` it will return `null` and you can't use a method or listener on it – codeMagic Aug 06 '13 at 18:47
I hope that makes sense – codeMagic Aug 06 '13 at 18:48
Perfect sense yes, I understand now. Thanks. Just wondering, would you be able to have a peek at my other question, its driving me mad. http://stackoverflow.com/questions/18080679/make-soundclip-in-a-listview-selectable-as-notification-ringtone – Jason Mills Aug 07 '13 at 13:40

I assume that "touch and hold" from the user means "longpress"?

If so, try looking at this post to see if your issues are similar. Perhaps you need to use setOnLongClickListener...
