我有一个Activity，它实现了View.OnClickListener以及来自不同类的其他几个抽象方法。问题是全局onClick没有被触发。
我必须手动为每个单独的视图设置一个新的OnClickListener，我无法在我的代码中找到Click事件被消耗的位置，并且无法传播到onClick(View view)方法。
这是我活动的主体：

答案 0 :(得分：1)
实施View.OnClickListener是不够的。对于要从中接收点击事件的所有视图，您需要使用setOnClickListener()注册侦听器。
答案 1 :(得分：1)
如果你想说＆＃34; Button1 ＆＃34;触发setOnClickListener然后添加此行Button1.setOnClickListener(this);
。
这样当单击Button1时，它将触发onClick方法
