Почему после перемещения ImageView фигура не возвращается в свое первоначальное состояние и так и остается навсегда спрятанной?

OnTouchListener onTch = new OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {

                ClipData clipData = ClipData.newPlainText("", "");
                View.DragShadowBuilder dsb = new View.DragShadowBuilder(v);
                if (event.getAction() == MotionEvent.ACTION_DOWN) {
                     Log.d(LOG_TAG, "ACTION_DOWN");
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {//.N
                        Log.d(LOG_TAG, "startDragAndDrop1");
                        v.startDragAndDrop(clipData, dsb, v, 0);
                        Log.d(LOG_TAG, "startDragAndDrop2");
                    } else {
                        Log.d(LOG_TAG, "startDragAndDrop3");
                        v.startDrag(clipData, dsb, v, 0);
                        Log.d(LOG_TAG, "startDragAndDrop4");
                    }
                   v.setVisibility(View.INVISIBLE);
                    Log.d(LOG_TAG, "1234");
