Android GridView Custom BaseAdapter ImageView ImageButton OnItemClick doesn´t work
- by Marek
i have a problem using a GridView with a CustomAdapter (extends BaseAdapter).
any Activity implements the OnItemClickListener.
if i use ImageView as item everything works fine, OnItemClick-Events will be fired/catched
I have not found a useful example for a GridView with a custom BaseAdapter using ImageButton.
Has anyone an idea? Many thanks in advantage!
Snippets:
class MyActivity extends Activity implements OnItemClickListener {
...
@Override
public void onCreate() {
...
GridView gridview = (GridView) findViewById(R.id.gridview);
gridview.setOnItemClickListener(this);
gridview.setAdapter(new ImageButtonAdapter(this));
}
...
@Override
public void onItemClick(AdapterView<?> adapter, View view, int arg2, long arg3)
{
Log.e("onItemClick()", "arg2=" + arg2 + ", arg3=" + arg3);
}
}
public class ImageButtonAdapter extends BaseAdapter
{
private Context mContext;
public LayoutMenuAdapter(Context c)
{
mContext = c;
}
public int getCount()
{
return mThumbIds.length;
}
public Object getItem(int position)
{
return null;
}
public long getItemId(int position)
{
return 0;
}
public View getView(int position, View convertView, ViewGroup parent)
{
/* IF I USE THIS PART EVERYTHING WORKS FINE */
// ImageView imageView;
// if (convertView == null) {
// imageView = new ImageView(mContext);
// imageView.setLayoutParams(new GridView.LayoutParams(100, 100));
// imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
// imageView.setPadding(0, 0, 0, 0);
// imageView.setFocusable(false);
// } else {
// imageView = (ImageView) convertView;
// }
// imageView.setImageResource(mThumbIds[position]);
// return imageView;
/* IF I USE THIS PART NO THE ACTIVITY/LISTENER RECEIVES NO EVENT */
ImageButton imageButton;
if (convertView == null) {
imageButton = new ImageButton(mContext);
imageButton.setLayoutParams(new GridView.LayoutParams(100, 100));
imageButton.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageButton.setPadding(0, 0, 0, 0);
imageButton.setFocusable(false);
} else {
imageButton = (ImageButton) convertView;
}
imageButton.setImageResource(mThumbIds[position]);
return imageButton;
}
// references to images
private Integer[] mThumbIds = { R.drawable.media};
}
