ok I have figured out how i can get different actions but i have
another problem now.
I have, like i already said, a list of flights..
when i click on a item in the list :
@Override
protected void onListItemClick(ListView l, View v, int position,
long id) {
Intent intent = new Intent(TravelPlannerHome.this,
FlightView.class);
intent.putExtra(FlightDbAdapter.KEY_ROWID, id);
startActivityForResult(intent, ACTIVITY_VIEW);;
super.onListItemClick(l, v, position, id);
}
I have to go to the activity FlightView:
Problem now is that he passes a rowid (unique id for database) but i
got this error:
03-25 00:18:19.742: ERROR/AndroidRuntime(3947): Caused by:
android.database.CursorIndexOutOfBoundsException: Index 0 requested,
with a size of 0
This worked when i hadn't a seperatedlist!
How can i fix this?
