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());
