Android完全退出应用程序



自定义一个继承自Application的类。用来记录所打开的Activity。

在每个Activity类的onCreate方法中调用ExitApplication.newInstance().addActivity(this);将Activity类添加到list中。

在退出时调用ExitApplication.newInstance().exit();循环执行finish();

public class ExitApplication extends Application {

private static List<Activity> acList = new LinkedList<Activity>();

private static ExitApplication instance = null;

private ExitApplication(){}

//单例模式

public static ExitApplication newInstance(){

if(null==instance){

instance = new ExitApplication();

}

return instance;

}

public void addActivity(Activity a){

acList.add(a);

}

public static void exit(){

for (Activity activity : acList) {

activity.finish();

}

System.exit(0);

}

}
