java - Android主页按钮，计时器问题

Question

每次按下主页按钮后运行应用程序时，我的应用程序似乎都会重新启动。该应用程序有一个Timer需要在按下主页按钮后继续。如果打开，我会覆盖后退按钮以最小化应用程序Timer，有没有办法使用主页按钮来做到这一点？

我onResume()现在是这样的：

@Override
public void onResume() {
    super.onResume();
}

Answer 1

The App has a Timer() which needs to continue once the Home button is pressed.

I suggest a different approach: log the time the Timer started and simply recreate the Timer in onResume(). This way you don't have to worry about the app being killed, running the Timer in a service, etc. If you want a task to be run while the app is paused, setup a AlarmManager event in onPause().

I override the Back button to Minimise the app if the Timer() is on, is there a way to do this with the Home button?

To address this specifically, you can use onUserLeaveHint() or the generalized onPause().
