Im using view.startDrag() to start dragging operation. While dragging, events are received in OnDragListener. Also im using DragShadowBuilder to show the last image of View B while dragging.
Is there a way to stop or cancel or abort dragging from some external events or operation? for example, there are 2 view, View A and View B, i'm dragging View B over View A. While dragging, due to some external event or operation, i want to cancel dragging operations or cancel OnDragListener (without removing my finger from the view B).
Code Snippet for DragShadowBuilder:
DragShadowBuilder shadowBuilder = new DragShadowBuilder(view) {
@Override
public void onDrawShadow(Canvas canvas) {
canvas.drawBitmap(b, 0, 0, new Paint());
super.onDrawShadow(canvas);
}
};
boolean dragSuccess = false;
dragSuccess = view.startDrag(null, shadowBuilder, view, 0);
Code Snippet for OnDragListener:
private final class ViewDragListener implements OnDragListener {
@Override
public boolean onDrag(View v, DragEvent event) {
int action = event.getAction();
switch (event.getAction()) {
case DragEvent.ACTION_DRAG_STARTED:
log("ACTION_DRAG_STARTED");
break;
case DragEvent.ACTION_DRAG_ENTERED:
log("ACTION_DRAG_ENTERED");
break;
case DragEvent.ACTION_DRAG_EXITED:
log("ACTION_DRAG_EXITED");
case DragEvent.ACTION_DROP:
log("ACTION_DROP");
mX = (int) event.getX();
mY = (int)event.getY();
break;
case DragEvent.ACTION_DRAG_ENDED:
log("ACTION_DRAG_ENDED");
//Doing some cleanup operations.
break;
case DragEvent.ACTION_DRAG_LOCATION:
log("ACTION_DRAG_LOCATION");
break;
default:
break;
}
return true;
}
}
