Question

如何退出启动了多个activity

Answer 1

public class ExitApplication extends Application { private List activityList = new LinkedList(); private static ExitApplication instance; private ExitApplication() { } // 单例模式中获取唯一的ExitApplication实例 public static ExitApplication getInstance() { if (null == instance) { instance = new ExitApplication(); } return instance; } // 添加Activity到容器中 public void addActivity(Activity activity) { activityList.add(activity); } // 遍历所有Activity并finish public void exit() { for (Activity activity : activityList) { activity.finish(); } System.exit(0); }将ExitApplication.getInstance().addActivity(this);添加到要退出的活动中。。。
