Android常用功能实例 如IMEI号

核心提示：}}public static class AlarmReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {Toast.makeText(context, "闹钟提

}

}

public static class AlarmReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

Toast.makeText(context, "闹钟提示：时间到!", Toast.LENGTH_LONG).show();

}

}

2、建立Intent和PendingIntent，来调用目标组件。

Java代码

Intent intent = new Intent(this, AlarmReceiver.class);

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);

Intent intent = new Intent(this, AlarmReceiver.class);

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);

3、设置闹钟

获取闹钟管理的实例：

Java代码

AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

设置单次闹钟：

Java代码

alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (5*1000), pendingIntent);

alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (5*1000), pendingIntent);

设置周期闹钟：

Java代码

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (10*1000), (24*60*60*1000), pendingIntent);

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (10*1000), (24*60*60*1000), pendingIntent);

搞定!当然这里闹钟的响应处理只是用的文字，你可以播放声音，或都用更复杂的一系统通知，在这里你就是上帝，一切由你做主。
