android值制作简易的闹钟和通知栏信息


1.制作一次性闹钟

2.制作周期闹钟

3.制作通知信息的弹出框

首先来一个闹钟思维导图吧

简单的思路:

设置(MainActivity)----------->广播接受者(RingReceiver)------------>响铃(RingActivity)---------->设置(MainAcitvity)




再来一个通知的思维导图


代码如下,里面有详解

RingReceiver广播接收者

[html] view plain copy
  1. package com.example.cookie.android0723alarmone;  
  2.   
  3. import android.content.BroadcastReceiver;  
  4. import android.content.Context;  
  5. import android.content.Intent;  
  6. import android.util.Log;  
  7.   
  8. /**  
  9.  * Created by Administrator on 2017/7/23 0023.  
  10.  */  
  11.   
  12. public class RingReceiver extends BroadcastReceiver {
