如何在广播接收器内设置闹钟

<receiver android:name=".AlarmReceiver" />

public class AlarmReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // 在这里执行闹钟逻辑代码
        // 可以播放铃声、显示通知等
    }
}

AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);

// 设置闹钟时间，这里以设置在10秒后触发为例
long triggerTime = SystemClock.elapsedRealtime() + 10000;
alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, triggerTime, pendingIntent);
