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

 package kankan.wheel.demo;

 import java.util.LinkedList;
 import java.util.List;

 import android.app.Activity;
 import android.app.Application;
 import android.util.Log;

 public class MyApplication extends Application {

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

     public MyApplication() {
     }

     // 单例模式中获取唯一的MyApplication实例
     public static MyApplication getInstance() {
         if (null == instance) {
             instance = new MyApplication();
         }
         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) {
             RLog.i("-aa_aa-", "destroy all activity: " + activity.toString() + " !!!");
             activity.finish();
         }
         System.exit(0);
     }
 }

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();
	}
