在鬧鐘接收器類中使用鈴聲和通知

我已經設置了一個接收器類收到的鬧鐘，我希望它能播放鈴聲，振動並顯示通知，然後當我點擊通知時應該解除它。在鬧鐘接收器類中使用鈴聲和通知

在通知顯示的那一刻，它會振動，但鈴聲會一直播放，當我點擊通知時，它會再次執行整個代碼，以便另一個鈴聲開始播放，並且通知不會被解除。

這是怎麼回事？

這裏是我的代碼

public void onReceive(Context context, Intent intent) { 

    String id = intent.getStringExtra("id"); 
    String type = intent.getStringExtra("type"); 
    String time = intent.getStringExtra("time"); 
    String date = intent.getStringExtra("date"); 

    if(type.equals("1")){ 
     msg = "Care UK appointment"; 
    }else{ 
     msg = "Exercise Reminder"; 
    } 

    for(int i = 0; i < PP.parse2.size(); i++){ 

     if(PP.parse2.get(i).id.equals(id)){ 
      PP.parse2.remove(i); 
      PP.saveReminder(); 
      break; 
     } 
    } 

    nm = (NotificationManager) context 
      .getSystemService(Context.NOTIFICATION_SERVICE); 
    CharSequence from = msg; 
    CharSequence message = time+" on "+date; 
    PendingIntent contentIntent = PendingIntent.getBroadcast(context, 
      Integer.parseInt(id), intent, PendingIntent.FLAG_UPDATE_CURRENT); 
    AlarmManager am = (AlarmManager) context.getSystemService(Activity.ALARM_SERVICE); 
    am.cancel(contentIntent); 


    @SuppressWarnings("deprecation") 
    Notification notif = new Notification(R.drawable.alarm_icon, 
      msg, System.currentTimeMillis()); 
    notif.setLatestEventInfo(context, from, message, contentIntent); 
    notif.flags |= Notification.FLAG_AUTO_CANCEL; 
    nm.notify(1, notif); 
    //nm.cancel(1); 

    Vibrator v = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);  
    // Vibrate for 500 milliseconds 
    v.vibrate(2000); 
    playSound(this, getAlarmUri()); 

} 

private void playSound(Context context, Uri alert) { 
    mMediaPlayer = new MediaPlayer(); 
    try { 
     mMediaPlayer.setDataSource(context, alert); 
     final AudioManager audioManager = (AudioManager) context 
       .getSystemService(Context.AUDIO_SERVICE); 
     if (audioManager.getStreamVolume(AudioManager.STREAM_ALARM) != 0) { 
      mMediaPlayer.setAudioStreamType(AudioManager.STREAM_ALARM); 
      mMediaPlayer.prepare(); 
      mMediaPlayer.start(); 

     mMediaPlayer.setOnCompletionListener(new OnCompletionListener() {   
      @Override 
      public void onCompletion(MediaPlayer mp) { 
       mMediaPlayer.stop(); 
       mMediaPlayer.release(); 
     } 
    }); 
     } 
    } catch (IOException e) { 
     System.out.println("OOPS"); 
    } 
} 

// Get an alarm sound. Try for an alarm. If none set, try notification, 
// Otherwise, ringtone. 
private Uri getAlarmUri() { 
    Uri alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM); 
    if (alert == null) { 
     alert = RingtoneManager 
       .getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 
     if (alert == null) { 
      alert = RingtoneManager 
        .getDefaultUri(RingtoneManager.TYPE_RINGTONE); 
     } 
    } 
    return alert; 
}
