随时随地退出程序

需要一个专门的集合类对对所有的活动进行管理就行了

package com.example.deligence.activitytest;import android.app.Activity;import java.util.ArrayList;import java.util.List;/** * Created by Deligence on 2017/4/16. */public class ActivityCollector {    public static List<Activity> activities = new ArrayList<Activity>();    public static void addActivity(Activity activity){        activities.add(activity);    }    public static void removeActivity(Activity activity){        activities.remove(activity);    }    public static void finishAll(){        for (Activity activity:activities) {            if(!activity.isFinishing()){                activity.finish();            }        }    }}

killProgress方法 用于杀掉一个进程

//杀掉当前程序代码android.os.Process.killProcess(android.os.Process.myPid());
