问题

A Template Method is a method that you may implement, but you must never call so which one method implemented by Android's Activity Class is NOT A Template Method?

模板方法是一个你可以实现的方法,但绝不能调用的方法,那么Android的Activity类中实现的哪个方法不是模板方法?

英文:

A Template Method is a method that you may implement, but you must never call so which one method implemented by Android's Activity Class is NOT A Template Method?

我可能没有正确理解问题,但我猜你在谈论生命周期方法:

  • onCreate()
  • onStart()
  • onRestart()
  • onResume()
  • onPause()
  • onStop()
  • onDestroy()

由于它们都可以被实现,但不应该被应用程序的代码直接调用。Activity 的每个其他方法都不是 "模板"(例如 findViewByIdgetContext)。

Activity 类的官方文档

英文:

I probably did not understand the question correctly, however I guess you are talking about lifecycle's methods:

  • onCreate()
  • onStart()
  • onRestart()
  • onResume()
  • onPause()
  • onStop()
  • onDestroy()

Since they all can be implemented but should never be directly called by application's code. Every other method of Activity is not "template" (e.g. findViewById or getContext).
