Java OnClickListener不会检测到单击矩形？

我有两个矩形，每个矩形正好占据屏幕的一半，我试图检测矩形上的点击

我的尝试： 我试图在两个矩形上都设置OnClickListener，但当我单击任一矩形时，都不会检测到单击。我非常确定它没有检测到点击，所以我登录到了监听器中，这证实了我的怀疑；未输入侦听器，因此未检测到任何单击

下面是我在活动中声明侦听器的位置：

下面是我的矩形类：

为什么在矩形视图上没有检测到单击？

您已经告诉视图当用户单击它时该做什么，但看起来该视图当前不可单击。试试这个：

topRectangle = new Rectangle(this, 0, 0, mScrWidth, mScrHeight/2, 0xC757FF57);
topRectangle.setClickable(true);

bottomRectangle = new Rectangle(this,0, mScrHeight /2, mScrWidth, mScrHeight, 0xDEFF5845 );
bottomRectangle.setClickable(true);

在我提供的活动代码的最后一行中，我为两个矩形编写了

setClickable

。无论如何，我还是用了一个触摸式监听器解决了这个问题。谢谢！：）
