     }
    })
    .setNegativeButton("NO",new DialogInterface.OnClickListener() {

    }
    });

    }

    public void quit() {
        onDestroy();
    }

请任何一个可以告诉我，我怎么能解决这个问题。

推荐答案

您可以调用您的活动完成（）方法和调用主屏幕（模拟为homeButton）编程是这样的：

you can call the finish() method on your activity and call the homescreen (simulate the homebutton) programmatically like this:

private void endApplication() {
    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.addCategory(Intent.CATEGORY_HOME);
    startActivity(intent);
}
