I ended up finding the problem. I was using the ImageAdapter code
form the Hello, Gallery example. That contained a line of code
referencing a Gallary:
imageView.setLayoutParams(new Gallery.LayoutParams(150, 120));
When used with a GridView, this obviously causes a class cast
exception.
Now that I have my GridView displaying properly in a popupwindow, I am
having trouble capturing the OnItemClick event. Below is my code.
OnItemClick is never being called when I make a selection in my
gridview in the popupwindow. Any ideas?
final GridView gView = (GridView) grid_layout.findViewById
(R.id.gridview_layout);
gView.setWillNotDraw(false);
gView.setFocusableInTouchMode(true);
gView.setClickable(true);
gView.setAdapter(new ImageAdapter(this));
final PopupWindow soundSelectorWindow = new PopupWindow(this);
soundSelectorWindow.setContentView(grid_layout);
soundSelectorWindow.setBackgroundDrawable(new BitmapDrawable());
soundSelectorWindow.setOutsideTouchable(false);
soundSelectorWindow.setTouchable(true);
gView.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView parent, View v, int position,
long id)
{
//Never gets here.
soundSelectorWindow.dismiss();
}
});
