android 完美退出所有Activity的demo

项目地址:https://github.com/libill/myapplication

利用android的wheel和参考android完美退出程序做出来的demo，结束掉所有打开的Activity，并把记录打开的Activity用log打印出来。

1、myapplication继承application

 1 package kankan.wheel.demo; 2  3 import java.util.LinkedList; 4 import java.util.List; 5  6 import android.app.Activity; 7 import android.app.Application; 8 import android.util.Log; 9 10 public class MyApplication extends Application {11 12     private static List<Activity> activityList = new LinkedList<Activity>();13     private static MyApplication instance;14 15     public MyApplication() {16     }17 18     // 单例模式中获取唯一的MyApplication实例19     public static MyApplication getInstance() {20         if (null == instance) {21             instance = new MyApplication();22         }23         return instance;24     }25 26     // 添加Activity到容器中27     public void addActivity(Activity activity) {28         activityList.add(activity);29     }30 31     // 遍历所有Activity并finish32     public void exit() {33         for (Activity activity : activityList) {34             RLog.i("-aa_aa-", "destroy all activity: " + activity.toString() + " !!!");35             activity.finish();36         }37         System.exit(0);38     }39 }

2、每一个Activity中的onCreate方法里添加该Activity到MyApplication对象的activityList

MyApplication.getInstance().addActivity(this);

3、结束所有Activity的时候调用exit方法

public void onBackPressed() {MyApplication myApplication = (MyApplication) WheelDemo.this.getApplication();Log.i("exit app:", "exit ok!");myApplication.exit();}
