OnClick() 事件和 OnClickListener 的区别? [英] Difference between OnClick() event and OnClickListener?
问题描述
在我的大部分项目中,我总是使用 onclick()
事件.但是,我读到了 OnClickListener()
.谁能告诉这两者有什么区别?哪一个最适合在 Android 应用程序中使用?
I'm always using onclick()
event in most of my projects. But, I read about OnClickListener()
. Can anyone tell what's the difference between these two? And which one is best to use in Android application?.
推荐答案
我不确定问题是否明确.View.OnClickListener
是一个接口,它定义了 onClick(View)
方法.如果你有一个打算监听点击的类,你应该既实现接口(如果还没有扩展一个这样做的类),也实现这个方法.您必须同时使用两者;它们不是某种替代品.
I'm not sure the question is clear. View.OnClickListener
is an interface, which defines the onClick(View)
method. If you have a class which intends to listen for clicks, you should both implement the interface (if not already extending a class that does), and implement this method too. You have to use both; they're not somehow alternatives.
