Η当我拖动一个按钮时，我可以设置一个自定义的可绘制的拖动阴影吗？

View button = findViewById(R.id.button);

button.setOnLongClickListener(new View.OnLongClickListener() {
    @Override
    public boolean onLongClick(View v) {
        // 创建自定义的拖动阴影
        View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(v) {
            @Override
            public void onDrawShadow(Canvas canvas) {
                // 绘制自定义的阴影效果
                Paint paint = new Paint();
                paint.setColor(Color.RED);
                canvas.drawRect(0, 0, getView().getWidth(), getView().getHeight(), paint);
            }
        };

        // 开始拖动操作
        v.startDrag(null, shadowBuilder, null, 0);

        return true;
    }
});
