Android สอบถามเรื่อง OndragListener ใน android อยากให้เช็คตัวที่เข้ามา drop อะครับ

@Override
public boolean onDrag(View view, DragEvent dragEvent) {

 // Get the drag drop action.
 int dragAction = dragEvent.getAction();

 if (dragAction == dragEvent.ACTION_DRAG_STARTED) {
  // Check whether the dragged view can be placed in this target view or not.
 } else if (dragAction == dragEvent.ACTION_DRAG_ENTERED) {
  // When the being dragged view enter the target view.
  return true;
 } else if (dragAction == dragEvent.ACTION_DRAG_EXITED) {
  // When the being dragged view exit target view area.
  return true;
 } else if (dragAction == dragEvent.ACTION_DRAG_ENDED) {
  // When the drop ended.
  return true;
 } else if (dragAction == dragEvent.ACTION_DROP) {
  // When drop action happened.
  // คำนวณในส่วนนี้

  // Get clip data in the drag event first.
  ClipData clipData = dragEvent.getClipData();

  // Get drag and drop item count.
  int itemCount = clipData.getItemCount();

  // If item count bigger than 0.
  if (itemCount > 0) {
   
   // Show a toast popup.
   Toast.makeText(context, Integer.toString(itemCount*5) + "Baht", Toast.LENGTH_LONG).show();
   return true;
  }

 } else if (dragAction == dragEvent.ACTION_DRAG_LOCATION) {
  return true;
 } else {
  Toast.makeText(context, "Drag and drop unknow action type.", Toast.LENGTH_LONG).show();
 }

 return false;
}
