Code for moving or dragging an image in sketchware android project

Now with the introduction of add source directly block in Sketchware, several such actions are possible which were not possible earlier. One such action is dragging an image by touching it.

It is very simple to move an image with movement of finger.

First insert an ImageView in VIEW area, inside any Layout. Name it as img. Upload image using image manager and set the image in ImageView.

After that in LOGIC area in onCreate event, use operator block add source directly, and add the following code:

img.setOnTouchListener(new OnTouchListener() { PointF DownPT = new PointF();
PointF StartPT = new PointF();
@Override public boolean onTouch(View v, MotionEvent event) { int eid = event.getAction(); switch (eid) {
case MotionEvent.ACTION_MOVE : PointF mv = new PointF( event.getX() - DownPT.x, event.getY() - DownPT.y);
img.setX((int)(StartPT.x+mv.x)); img.setY((int)(StartPT.y+mv.y));
StartPT = new PointF( img.getX(), img.getY() ); break;
case MotionEvent.ACTION_DOWN : DownPT.x = event.getX();
DownPT.y = event.getY();
StartPT = new PointF( img.getX(), img.getY() ); break;
case MotionEvent.ACTION_UP : break; default : break;} return true;} });

Now save and run the project. You will be able to move the image with your finger.

      Yes. Just rename Imageview from Imageview1 to img.
      Then put the code above in add source directly block.

    how do you get the dragged image back to the original position if it's not dropped at a certain position?
    I mean like a puzzle game, you will understand.

    I want to imply the drag and drop function like that, so when the img that is dropped does not match the given position, then the img returns to its original position, and if the dragged img is dropped at the correct position then img had moved
