本文讨论了一个常见的Android开发问题：当在同一个View上嵌套点击监听器时，可能会遇到的命名冲突错误。文章提供了作者的实际经验，并指出通过更改View变量名称可以有效解决此问题。

at android.view.View.performClick(View.java:2408)

    

  就是指 View 定义的变量的名字 有相同的!

       所以!

  

  上次我做项目的时候!发现,我click中嵌套click 就出现这样类似的错误!

     至于具体的我记得不太请错了!

   反正就是两个命名的问题!改下变量名就OK了

Android中performClick方法---代码调用点击事件（模拟去触摸控件）
lplj717的博客

最近看到view一个方法performClick，这个方法的作用:使用代码主动去调用控件的点击事件(模拟人手去触摸控件) 这个一般很少用的，除非在特殊情况下，比如一开始初始化需要非人为的进行一次点击，但大多数情况我们都能在代码中编写相关逻辑代码完成，如果实在办不到还可以使用接口回调，其实很多东西我们经过代码处理能达到实现效果，但有直接能用的东西我们不建议绕大弯，毕竟精力有限，程序员是推崇“偷懒”
