我试图把一个额外的消息，在我的意图传递给AlarmManager在以后的时间被触发。我的onReceive正确触发，但extras.getString（）返回null

设置：

 公共PendingIntent getPendingIntent（INT uniqueRequest code，字符串额外的）{
    意向意图=新的意图（这一点，ActionReceiver.class）;
    intent.putExtra（额外的，另计）;
    PendingIntent pendingIntent = PendingIntent.getBroadcast（这一点，uniqueRequest code，
            意图，0）;
    返回pendingIntent;
}

公共无效setSilentLater（TimeRule timeRule）{
    布尔[]平日= timeRule.getReoccurringWeekdays（）;
    INT DAYOFWEEK = 0;

    对于（布尔日：周一至周五）{
        一周中的某天++;
        如果（天==真）{
            日历CAL = Calendar.getInstance（）;

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

            cal.set（Calendar.DAY_OF_WEEK，星期几）;
            cal.set（Calendar.HOUR_OF_DAY，
                    。timeRule.getStartTime（）得到（Calendar.HOUR_OF_DAY））;
            cal.set（Calendar.MINUTE，
                    。timeRule.getStartTime（）得到（Calendar.MINUTE））;
            cal.set（Calendar.SECOND，0）;
            cal.set（Calendar.MILLISECOND，0）;

            alarmManager.setRepeating（AlarmManager.RTC_WAKEUP，
                    cal.getTimeInMillis（），3600000 * 7，getPendingIntent（0，RINGER_OFF））;
  }
 }
}
 

在此触发，消息是空的：

 公共类ActionReceiver扩展的BroadcastReceiver {

    @覆盖
    公共无效的onReceive（上下文的背景下，意图意图）{
         捆绑额外= intent.getExtras（）;
         字符串消息= extras.getString（额外）; //空
         如果（消息==RINGER_OFF）
         {
             AudioManager上午=（AudioManager）context.getSystemService（Context.AUDIO_SERVICE）;
             am.setRingerMode（AudioManager.RINGER_MODE_SILENT）;
         }
         否则，如果（消息==RINGER_ON）
         {
             AudioManager上午=（AudioManager）context.getSystemService（Context.AUDIO_SERVICE）;
             am.setRingerMode（AudioManager.RINGER_MODE_NORMAL）;
         }
    }
}
 

解决方案

  //前更换code
    捆绑额外= intent.getExtras（）;
    字符串消息= extras.getString（额外）;
//后更换code
     字符串消息= intent.getStringExtra（额外）;

                     要么

//前替换code
   意向意图=新的意图（这一点，ActionReceiver.class）;
   intent.putExtra（额外的，另计）;
//后更换code
   意向意图=新的意图（这一点，ActionReceiver.class）;
   束束=新包（）;
   bundle.putString（额外的，另计）;
   intent.putExtras（包）;
 

I am trying to put an extra message in my intent to pass to AlarmManager to be triggered at a later time. My onReceive triggers correctly but extras.getString() returns null

Setup:

public PendingIntent getPendingIntent(int uniqueRequestCode, String extra) {
    Intent intent = new Intent(this, ActionReceiver.class);
    intent.putExtra("EXTRA", extra);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, uniqueRequestCode,
            intent, 0);
    return pendingIntent;
}

public void setSilentLater(TimeRule timeRule) {
    boolean[] weekdays = timeRule.getReoccurringWeekdays();
    int dayOfWeek = 0;

    for (boolean day : weekdays) {
        dayOfWeek++;
        if (day == true) {
            Calendar cal = Calendar.getInstance();

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

            cal.set(Calendar.DAY_OF_WEEK, dayOfWeek);
            cal.set(Calendar.HOUR_OF_DAY,
                    timeRule.getStartTime().get(Calendar.HOUR_OF_DAY));
            cal.set(Calendar.MINUTE,
                    timeRule.getStartTime().get(Calendar.MINUTE));
            cal.set(Calendar.SECOND, 0);
            cal.set(Calendar.MILLISECOND, 0);

            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                    cal.getTimeInMillis(), 3600000 * 7, getPendingIntent(0, "RINGER_OFF"));
  }
 }
}

When this triggers, message is empty:

public class ActionReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
         Bundle extras = intent.getExtras();
         String message = extras.getString("EXTRA"); //empty        
         if(message == "RINGER_OFF")
         {
             AudioManager am = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
             am.setRingerMode(AudioManager.RINGER_MODE_SILENT);
         }
         else if(message == "RINGER_ON")
         {
             AudioManager am = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
             am.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
         }
    }
}

// before replace code 
    Bundle extras = intent.getExtras();
    String message = extras.getString("EXTRA");
// after replace code 
     String message = intent.getStringExtra("EXTRA");

                     OR

// before replace code 
   Intent intent = new Intent(this, ActionReceiver.class);
   intent.putExtra("EXTRA", extra);
// after replace code 
   Intent intent = new Intent(this, ActionReceiver.class);
   Bundle bundle = new Bundle();
   bundle.putString("EXTRA", extra);
   intent.putExtras(bundle);
