Android完全退出多个activity程序设计

设计思路：每打开一个Activity，就记录下来，在需要退出时，关闭每一个Activity即可。使用单例模式创建一个Activity管理对象，该对象中有一个Activity容器。/*** @author Administrator 易皇星 2016-01-12**/public class AppManager {private static Stack<Activity> activityStack;private static AppManager instance;private AppManager() {}/*** 单一实例*/public static AppManager getAppManager() {if (instance == null) {instance = new AppManager();}return instance;}/*** 添加Activity到堆栈*/public void addActivity(Activity activity) {if (activityStack == null) {activityStack = new Stack<Activity>();}activityStack.add(activity);}/*** 获取当前Activity（堆栈中最后一个压入的）*/public Activity currentActivity() {Activity activity = activityStack.lastElement();return activity;}/*** 结束当前Activity（堆栈中最后一个压入的）*/public void finishActivity() {Activity activity = activityStack.lastElement();finishActivity(activity);}/*** 结束指定的Activity*/public void finishActivity(Activity activity) {if (activity != null) {activityStack.remove(activity);activity.finish();activity = null;}}/*** 结束指定类名的Activity*/public void finishActivity(Class<?> cls) {for (Activity activity : activityStack) {if (activity.getClass().equals(cls)) {finishActivity(activity);}}}/*** 结束所有Activity*/public void finishAllActivity() {for (int i = 0, size = activityStack.size(); i < size; i++) {if (null != activityStack.get(i)) {activityStack.get(i).finish();}}activityStack.clear();}/*** 退出应用程序*/public void exitApp(Context context) {try {finishAllActivity();System.exit(0);} catch (Exception e) {}}}//怎么调用:调用的时候最好是在baseActivity中调用，这样就不需要在每个activity中调用，利用继承的关系在每个Activity的onCreate()方法中添加下面代码

AppManager.getAppManager().addActivity(this);
