覆盖Android所有活动的OnResume()方法 [英] Override OnResume() method of all activities Android

问题描述

我的应用程序有10多个活动，我想在所有活动中使用相同的代码覆盖方法onResume().

I have and app with more than 10 activities and I would like override the method onResume() with the same code in all of them.

我知道我可以在每个活动中重写此方法，但我正在寻找一种有效的解决方案.

I know that I can override this method in each activity, but I'm looking for an efficient solution.

此外，我想在此onResume中显示一条消息，该消息取决于活动的来源，例如:如果您在MainActivity中，则我希望此常见的onResume检测到该活动来自此活动并显示I'm coming from MainActivity

Moreover I would like inside this onResume show a message depending what activity is coming from, for example: if you are in the MainActivity I want that this common onResume detects that is coming from this activity and show I'm coming from MainActivity

谢谢.

推荐答案

您应在BaseClass中使用Override活动，并在其他活动中使用BaseClass代替活动":

you should Override activity in a BaseClass and use your BaseClass instead of Activity in the other activities:

public class BaseClass extends Activity 
{

  public void onResume() 
  {
    // common code
  } 
}

public class OtherClass extends BaseClass 
{
}
