转到主屏幕，而不是先前的活动 [英] Go to home screen instead of previous Activity

问题描述

我知道这个问题已经被问过很多次了，但是任何一种解决方案都不起作用，我的情况也有所不同.

I know this question has been asked many times before, but any of the solution is not working and my situation is a little bit different.

我有一个Activity，可以从许多不同的活动中调用它.但是我希望当用户按下后退"按钮时，应用程序应该转到主屏幕，而不是先前的活动.

I've an Activity which can be called from many different Activities. But I want when the user presses back button, instead of previous activity, app should go to Home screen.

一种使用StartActivityFromResult()的方法，但是随后我将不得不在每个调用Activity中使用它.

One way to use StartActivityFromResult() but then I'll have to use it in every calling Activity.

推荐答案

，您可以按如下方法覆盖onBackPressed()方法.应该可以.

you can override onBackPressed() method as follows. It should work.

public void onBackPressed() {
    Intent startMain = new Intent(Intent.ACTION_MAIN);
    startMain.addCategory(Intent.CATEGORY_HOME);
    startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(startMain);
}
