GridView onTouch
- by Jeff
I am trying to set up a GridView of buttons that responds to onTouch. For example, if I swipe my finger across the screen horizontally, vertically or diagonally then I want the buttons which were touched to be selected. I tried setting OnTouchListener's for the buttons, but this didn't work, only the first button in the drag event received the onTouch events.
Next I tried creating an OnTouchListener for the GridView and then using the X,Y coords to determine which buttons where touched. This doesn't seem to work either since the MOTION_DOWN events are only passed to the GridView's onTouch() if I start the drag on the very edge of the GridView. In fact if I drag my finger horizontally across the grid, the onTouch events aren't fired at all unless I start the drag at the edge of the GridView. Does anyone know of a better way to do this?
Thanks in advance.
gridview.setOnTouchListener(new View.OnTouchListener()
{
@Override
public boolean onTouch(@SuppressWarnings("unused") View view, MotionEvent event)
{
float X = event.getX();
float Y = event.getY();
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
System.out.println("Down: " + X + "," + Y);
break;
case MotionEvent.ACTION_MOVE:
System.out.println("Move: " + X + "," + Y);
break;
case MotionEvent.ACTION_UP:
System.out.println("Up: " + X + "," + Y);
break;
}
return true;
}
}
