Thank you bob,
exactly item.getMenuInfo(); return a null value, but I dont know why?
however item.getItemId() works fine. as shown bellow.
without your help guys, it would have been for me really a
mysterious/aborious error to fix, thanks for
---------------------
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
if (info == null) Toast.makeText(getApplicationContext(), "info null",
Toast.LENGTH_LONG).show();
else Toast.makeText(getApplicationContext(), "info not null",
Toast.LENGTH_LONG).show();
switch (item.getItemId()) {
case EDIT_ID:
//editNote(info.id);
editNote(item.getItemId());
return true;
case DELETE_ID:
//deleteNote(info.id);
deleteNote(item.getItemId());
return true;
default:
return super.onContextItemSelected(item);
}
}
