How to start animation when I'm pressing on item of ListView?
- by Ares
I want to implement next functional: When I'm tapping on ListView's item, it's turning into red color. If I release it has to reverse color back. I made transition drawable and set it as item's background. I tried to implement SimpleGestureListener and started animation on onDown and reversed it on onSingleTapUp events, but it doesn't give me any results (works fine, but items don't turn into red). If I return super.onDown (not true), the onLongPress raise every time(even I manage to release it).
@Override
public boolean onDown(MotionEvent e) {
if(_currentRow.getTag()!=null)
if(_currentRow.getTag().toString().equals("anim"))
_currentRow.setBackgroundDrawable(context.getResources()
.getDrawable(R.xml.listviewitem_yellow_red));
_drawable = (TransitionDrawable) _currentRow.getBackground();
_drawable.startTransition(500);
return true;
//super.onDown(e); // IF I UNCOMMENT IT TURNS INTO RED, BUT TRIGGERED onLongClick event!!!
}
@Override
public boolean onSingleTapUp(MotionEvent e) {
if(_drawable!=null){
_drawable.reverseTransition(500);
}
return super.onSingleTapUp(e);
}
@Override
public void onLongPress(MotionEvent e) {
if(getLongClickListener()!=null)
getLongClickListener().onLongClick(_currentRow, _object);
super.onLongPress(e);
}
If someone knows how to solve this problem, please help me.
