关闭所有的activity

一、创建类ActivityCollect,在这个类中编写addActivity,removeActivity和finishAll等方法。

public class ActivityCollector {

    public static List<Activity> activities = new ArrayList<>();

    public static void addActivity(Activity activity) {
        activities.add(activity);
    }

    public static void removeActivity(Activity activity) {
        activities.remove(activity);
    }

    public static void finishAll() {
        for (Activity activity : activities) {
            if (!activity.isFinishing()) {
                activity.finish();
            }
        }
    }
}

二、创建类BaseActivity,继承AppCompatActivity，并重写onCreate,onDestroy

//@RuntimePermissions
public class BaseActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ActivityCollector.addActivity(this);//加入这一行
    }
    @Override
    protected void onDestroy() {
        super.onDestroy();
        ActivityCollector.removeActivity(this);//加入这一行
    }
}

三、让所有的Activity都继承BaseActivity

然后就可以在你所希望的地方调用finishAll方法。

ActivityCollector.finishAll();
