Why, after moving the ImageView, does the shape not return to its original state and remains hidden forever?

Why doesn't the shape return to its original state after moving the ImageView and remain hidden forever?

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");
                    return true;
                }else {
                    return false;
                }
            }
        };
