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();
	}
