Android 安卓&x27；s报警管理器错误周期

Android 安卓&x27；s报警管理器错误周期,android,alarmmanager,Android,Alarmmanager,我正在为我的应用程序创建AlarmManager，以便在不同时段发送短信。当我为AlarmManager设置一个时间（例如5分钟）时，它几乎会立即唤醒1-2次，但在这之后它工作正常。在我改变周期值后，情况会重复。我认为停止AlarmManager或设置中继器是有问题的这是我的makeAlarm功能： private void makeAlarm() { cancelAlarm(); Intent i = new Intent(this, SmsAlarmReceiver.

我正在为我的应用程序创建AlarmManager，以便在不同时段发送短信。当我为AlarmManager设置一个时间（例如5分钟）时，它几乎会立即唤醒1-2次，但在这之后它工作正常。在我改变周期值后，情况会重复。我认为停止AlarmManager或设置中继器是有问题的

这是我的

makeAlarm

功能：

  private void makeAlarm() {
    cancelAlarm();

    Intent i = new Intent(this, SmsAlarmReceiver.class);

    PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), SmsAlarmReceiver.REQUEST_CODE,
            i, PendingIntent.FLAG_UPDATE_CURRENT);

    long firstMillis = System.currentTimeMillis();

    SharedPreferences refreshSettings = getSharedPreferences("com.example.xd720p.sensorcontroller_09082016",
            Context.MODE_PRIVATE);

    double refreshForTValue = Double.valueOf(refreshSettings.getString("tempPeriod", "30"));

    if (refreshForTValue <= 0 ) {
        cancelAlarm();
    } else {
        long period = Math.round(refreshForTValue * 60 * 1000);
        AlarmManager alarm = (AlarmManager) getSystemService(ALARM_SERVICE);
        alarm.setRepeating(AlarmManager.RTC_WAKEUP, firstMillis,
                firstMillis + period, pendingIntent);
    }
}

  private void cancelAlarm() {
    try {
        Intent i = new Intent(this, SmsAlarmReceiver.class);
        PendingIntent pIntent = PendingIntent.getBroadcast(this.getApplicationContext(), SmsAlarmReceiver.REQUEST_CODE,
                i, 0);

        AlarmManager alarm = (AlarmManager) getSystemService(ALARM_SERVICE);

        alarm.cancel(pIntent);
        pIntent.cancel();
    } catch (Exception e) {
        e.printStackTrace();
    }

}

    private void makeAlarm() {
    cancelAlarm();

    Intent i = new Intent(this, SmsAlarmReceiver.class);

    PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), SmsAlarmReceiver.REQUEST_CODE,
            i, PendingIntent.FLAG_CANCEL_CURRENT);

    SharedPreferences refreshSettings = getSharedPreferences("com.example.xd720p.sensorcontroller_09082016",
            Context.MODE_PRIVATE);

    double refreshForTValue = 0;


    refreshForTValue = Double.valueOf(refreshSettings.getString("tempPeriod", "30"));


    if (refreshForTValue <= 0 ) {
        cancelAlarm();
    } else {
        long period = Math.round(refreshForTValue * 60 * 1000);
        AlarmManager alarm = (AlarmManager) getSystemService(ALARM_SERVICE);
        long firstMillis = System.currentTimeMillis();
        alarm.setRepeating(AlarmManager.RTC_WAKEUP, firstMillis + period,
                period, pendingIntent);
    }
}

这是我的

SmsAlarmReceiver

类，它扩展了

BroadcastReceiver

：

  public class SmsAlarmReceiver extends BroadcastReceiver {
public static final int REQUEST_CODE = 322;


  @Override
  public void onReceive(Context context, Intent intent) {

      Intent i = new Intent(context, SmsSenderService.class);
      context.startService(i);
  }
}

我在

MainActivity

中的

onCreate

方法中创建报警。当我改变周期值时，我也会停止我的报警并重新设置。这个值存储在

SharedReferences

中，因此我尝试在

onSharedPreferenceChanged

中重新创建报警，但在我的情况下没有任何意义。

最后，我解决了它！以下是我在

makeAlarm（）

函数中的解决方案：

  private void makeAlarm() {
    cancelAlarm();

    Intent i = new Intent(this, SmsAlarmReceiver.class);

    PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), SmsAlarmReceiver.REQUEST_CODE,

            Context.MODE_PRIVATE);

    double refreshForTValue = Double.valueOf(refreshSettings.getString("tempPeriod", "30"));

    if (refreshForTValue <= 0 ) {
        cancelAlarm();
    } else {
        long period = Math.round(refreshForTValue * 60 * 1000);
        AlarmManager alarm = (AlarmManager) getSystemService(ALARM_SERVICE);
