finish 所有的Activity

[android]代码库

public class ClientExitApplication extends Application {

	private List<Activity> activityList = new LinkedList<Activity>();
	private static ClientExitApplication instance;

	private ClientExitApplication() {
		
	}

	public static ClientExitApplication getInstance() {
		if (null == instance) {
			instance = new ClientExitApplication();
		}
		return instance;

	}

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


	public void exit() {

		for (Activity activity : activityList) {
			activity.finish();
		}

		System.exit(0);

	}
}

其他Activity中调用 	ClientExitApplication.getInstance().addActivity(this);  
触发退出时嗲用 	ClientExitApplication.getInstance().exit();
