I found something for you. Let me implement some source code.

 private OnTouchListener onTouchListener() {


return new OnTouchListener() {

   @SuppressLint("ClickableViewAccessibility")
   @Override
   public boolean onTouch(View view, MotionEvent event) {
    
final int x = (int) event.getRawX();
final int y = (int) event.getRawY();

switch (event.getAction() & MotionEvent.ACTION_MASK) {

case MotionEvent.ACTION_DOWN:
 RelativeLayout.LayoutParams lParams = (RelativeLayout.LayoutParams) 
 view.getLayoutParams();
 
 xDelta = x - lParams.leftMargin;
 yDelta = y - lParams.topMargin;
 break;
 
case MotionEvent.ACTION_UP:
 Toast.makeText(TouchActivity.this,
   "thanks for new location!", Toast.LENGTH_SHORT)
   .show();
 break;
 
case MotionEvent.ACTION_MOVE:
 RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) view
   .getLayoutParams();
 layoutParams.leftMargin = x - xDelta;
 layoutParams.topMargin = y - yDelta;
 layoutParams.rightMargin = 0;
 layoutParams.bottomMargin = 0;
 view.setLayoutParams(layoutParams);
 break;
}
mainLayout.invalidate();
return true;
}


};
 }

To run the source code on imageView

imageView.setOnTouchListener(onTouchListener());
