1、先添加權(quán)限

<uses-permission android:name="android.permission.RESTART_PACKAGES" />

2、添加Activity管理類

package net.oschina.app;import java.util.Stack;import android.app.Activity; import android.app.ActivityManager; import android.content.Context;/*** 應(yīng)用程序Activity管理類* @author liux*/ public class AppManager {private static Stack<Activity> activityStack;private static AppManager instance;private AppManager(){}/*** 單一實(shí)例*/public static AppManager getAppManager(){if(instance==null){instance=new AppManager();}return instance;}/*** 添加Activity到堆棧*/public void addActivity(Activity activity){if(activityStack==null){activityStack=new Stack<Activity>();}activityStack.add(activity);}/*** 獲取當(dāng)前Activity（堆棧中最后一個(gè)壓入的）*/public Activity currentActivity(){Activity activity=activityStack.lastElement();return activity;}/*** 結(jié)束當(dāng)前Activity（堆棧中最后一個(gè)壓入的）*/public void finishActivity(){Activity activity=activityStack.lastElement();if(activity!=null){activity.finish();activity=null;}}/*** 結(jié)束指定的Activity*/public void finishActivity(Activity activity){if(activity!=null){activityStack.remove(activity);activity.finish();activity=null;}}/*** 結(jié)束指定類名的Activity*/public void finishActivity(Class<?> cls){for (Activity activity : activityStack) {if(activity.getClass().equals(cls) ){finishActivity(activity);}}}/*** 結(jié)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();}/*** 退出應(yīng)用程序*/public void AppExit(Context context) {try {finishAllActivity();ActivityManager activityMgr= (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);activityMgr.restartPackage(context.getPackageName());System.exit(0);} catch (Exception e) { }} }

3、使用AppManager類

1）當(dāng)Activity啟動(dòng)時(shí)，在onCreate中添加：AppManager.getAppManager().addActivity(this);

2）當(dāng)要退出Activity時(shí)，使用：AppManager.getAppManager().AppExit(this);
　　

總結(jié)
