我有几个关于android视图的问题。我是新手，所以如果我的问题看起来很荒谬，请给我正确的提示:)所以我正在尝试制作记忆游戏。这是我的mainLayout代码。

好吧，在创建Activiti之后的第一步中，我将OnClickListener设置为每张卡片（pic_a1，pic_a2 ... pic_e5）和ImageView paPreviewView的可见性为隐形（我想要显示所选卡片的图像）。然后，当我点击pic_a1是paPreviewView显示。还行吧。我的问题是。
1）在我的这个例子的早期版本中，我通过调用隐藏了paPreviewView ImageView
paPreviewView.setVisibility(View.INVISIBLE);
要么
paPreviewView.setVisibility(View.GONE);
但它没有正常工作。因为方法OnClickListener.onClick仅从隐藏的paPreviewView ImageView调用。所以我试图从paPreviewView中删除OnClickListener，但它没有帮助。只有工作解决方案被删除（用于隐藏）并从/向mainPanel添加（用于显示）paPreviewView。
我的问题是为什么？为什么paPreviewView在隐藏paPreviewView时会引发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）？
非常感谢任何想法:)
在这种情况下使用的正确函数是：
paPreviewView.setClickable(false);
ImageView.setVisibility()只改变视图的“可见性”，它仍然有监听器注册。
您可以使用：
paPreviewView.setEnabled(false);
不接收点击事件。
