Cannot execute OnItemClick for GridView in PopupWindow
I have a gridView that I display in a popupwindow (the gridview is in a transparent layout, which inherits from linearlayout and just has a partially transparent background). I can never get this GridView's OnItemClick to execute. When I touch an image in my gridview it appears to be clicked (image bachgrond changes), but OnItemClick is not being called.
Below is the code for my Adapter and my popupview containing the gridView. Thanks!
//Adapter
public class ImageAdapter extends BaseAdapter { private Context mContext; private int itemBackground;
public ImageAdapter(Context c) {
mContext = c;
//---setting the style---
TypedArray a = c.obtainStyledAttributes(R.styleable.Gallery1);
itemBackground = a.getResourceId(R.styleable.Gallery1_android_galleryItemBackground, 0);
a.recycle();
}
....
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView;
if (convertView == null) {
imageView = new ImageView(mContext);
} else {
imageView = (ImageView) convertView;
}
imageView.setImageResource(images[position]);
imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
imageView.setBackgroundResource(itemBackground);
return imageView;
}
public Integer[] images = {
R.drawable.sound1,
R.drawable.sound2,
R.drawable.sound3,
R.drawable.sound4
};
}
//////////In Activity, onCreate////////
...
final LayoutInflater inflater=(LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final TransparentLayout musicGrid = (TransparentLayout) inflater.inflate(R.layout.gridviewpopup, null, false);
final GridView gView = (GridView) musicGrid.findViewById(R.id.music_gridview);
gView.setAdapter(new ImageAdapter(this));
final PopupWindow soundSelectorWindow = new PopupWindow(this);
soundSelectorWindow.setContentView(musicGrid);
soundSelectorWindow.setTouchable(true);
gView.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView<?> parent, View v, int position, long id)
{
//NEVER GETS HERE
soundSelectorWindow.dismiss();
}
});

Answer 1
what happens if you remove soundSelectorWindow.setTouchable(true);
Answer 2
I can't explain why the OnItemClickListener isn't working, but when I substituted with OnTouchListener it worked. Do you need to differentiate between which item is clicked or is it enough just to know that the popup was clicked? From you code it looks like the latter, so OnTouch should work:
popup.setTouchable(true);
popup.setFocusable(true);
gView.setClickable(true);
gView.setOnTouchListener(new View.OnTouchListener()
{
public boolean onTouch(View v, MotionEvent event)
{
popup.dismiss();
return true;
}
});

Check the VM size of the Emulator so that its good enough to run your app in its VM.
Check the Size of your <ApplicationName.apk>. Keep it in min sized so that Emulator will not find any difficulties in executing your app.
