        getMenuInflater().inflate(R.menu.activity_main, menu);

}

好的，在创建 Activiti 后的第一步中，我将 OnClickListener 设置为每张卡片（pic_a1，pic_a2 ... pic_e5），并将 ImageView paPreviewView 的可见性设置为不可见（我想显示所选卡片的图像）。然后当我点击 pic_a1 时显示 paPreviewView。还行吧。我的问题是。

1）在我这个例子的早期版本中，我通过调用隐藏了 paPreviewView ImageView

paPreviewView.setVisibility(View.INVISIBLE);

或者

paPreviewView.setVisibility(View.GONE);

但它不能正常工作。因为仅从隐藏的 paPreviewView ImageView 调用方法 OnClickListener.onClick。所以我试图从 paPreviewView 中删除 OnClickListener 但它没有帮助。唯一可行的解​​决方案是从 / 到 mainPanel 删除（用于隐藏）并添加（用于显示）paPreviewView。

我的问题是为什么？为什么在 paPreviewView 隐藏时 paPreviewView 会引发 onClick 事件？

2）我的第二个问题是。比我为这个例子做的更好的解决方案（我的意思是纸牌游戏）？

非常感谢您的任何想法:)

在这种情况下使用的正确函数是：

paPreviewView.setClickable(false);

ImageView.setVisibility()仅更改视图的“可见性”，并且仍然注册了侦听器。

您可以使用：

paPreviewView.setEnabled(false);

不接收点击事件。
