Android 设置闹铃步骤和基础代码

private void setAlarmTime(Context context,long timeInMillis) {
  AlarmManager am = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
  Intent intent = new Intent(”android.alarm.demo.action“);
  PendingIntent sender = PendingIntent.getBroadcast(
      context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
  int interval = 60 * 1000;//闹铃间隔， 这里设为1分钟闹一次，在第2步我们将每隔1分钟收到一次广播
  am.setRepeating(AlarmManager.RTC_WAKEUP, timeInMillis, interval, sender)
  }

public class AlarmReceiver extends BroadcastReceiver {
  public void onReceive(Context context, Intent intent) {
  if (”android.alarm.demo.action“.equals(intent.getAction())) {
    //第1步中设置的闹铃时间到，这里可以弹出闹铃提示并播放响铃
    //可以继续设置下一次闹铃时间;
    return;
  }
  }
}

<receiver android:name="AlarmReceiver">
    <intent-filter>
      <action android:name="android.alarm.demo.action" />
    </intent-filter>
</receiver>

public class BootReceiver extends BroadcastReceiver {
  public void onReceive(Context context, Intent intent) {
  String action = intent.getAction();
  if (action.equals(Intent.ACTION_BOOT_COMPLETED)) {
    //重新计算闹铃时间，并调第一步的方法设置闹铃时间及闹铃间隔时间
  }
  }
}

<receiver android:name="BootReceiver">
    <intent-filter>
      <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>
