Android开发日志 闹钟
近期要做个东西,需要设计到闹钟的设置.
现在把遇到的问题和详细步骤的给大家分享下~
首先 闹钟是位于ALARM_SERVICE用AlarmManager进行管理
AlarmManager am = (AlarmManager)getSystemService();
用这一句就可以直接得到闹钟管理
然后你就可以设置闹钟了.
am.setRepeating(type, triggerAtTime, interval, operation)
或者
am.set(type, triggerAtTime, operation)
type的话用AlarmManager.RTC_WAKEUP或者其他,参考SDK文档~
operation是一个PendingIntent
之所以要这个..是因为我们需要在程序退出后.时间到了也可以正常被系统调入然后执行
创建一个类继承BroadcastReceiver

然后onReceive上面就是闹钟响的时候执行的代码
还有就是这个类必须在mainfest.xml里面注册成监听
<receiver android:name=".AlarmReceiver" android:process=":remote" />
然后就可以使用了~
