This is my 'main' code.. i want detect the press here
ListView lv = (ListView)findViewById(R.id.listView);
Item_ListAdapter adapter = new Item_ListAdapter(ListActivity.this, items);
lv.setAdapter(adapter);
lv.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parnet, android.view.View view, int position, long id) {
// Que item ha sido pulsado
Toast.makeText(getApplicationContext(), String.valueOf(position), Toast.LENGTH_SHORT).show();
Log.d("aaa", String.valueOf(position) );
}
});
Answer
I believe in order to have BOTH the listView row and the ImageButton clickable, you'll need to set both of these on the ImageButton object:
android:focusable="false"
android:focusableInTouchMode="false"
Give that a shot. I'd also try using an onClickListener on your ImageButton instead of the touchListener.
