Android Studio应用程序未在finish（）上关闭

Question

So i have a button in the bottom layout , when i press it i intend to close the application.

instead what seems to happen is, what i think is the viewflipper closes and the bottom and top bar remain active and the application doesn't close.

this is the result when i press the Close button.

CODE

finish();

Answer 1

As per the documentation, finish() closes the Activity that you call finish() on, not your entire application.

Say you have two Activities, ActivityOne and ActivityTwo . ActivityOne calls startActivity(new Intent(this, ActivityTwo.class)) to start ActivityTwo . If you now call finish() within ActivityTwo , the first activity will be displayed again.

This is tied to the back stack - when you finish one Activity, the next Activity on the back stack will be displayed.

If you want to close all of your Activities, you must call finish() on each of those Activities.

You can use

Intent startMain = new Intent(Intent.ACTION_MAIN);
            startMain.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startMain.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
            startMain.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
            startMain.addCategory(Intent.CATEGORY_HOME);
            startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(startMain);
