La barre de menu s'exécute plus rapidement sur chaque onClick

Question

J'essaie de faire un simple enregistreur audio. Le problème avec l'enregistreur audio est que, chaque fois que la barre de progression devient plus rapide. Cela fonctionnerait bien au premier tour, mais si vous annulez l'audio et que vous voulez revenir la deuxième fois, cela devient plus rapide.

 recordButton.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        if (recorder == null) { 
         recorder = new MediaRecorder(); 
        } 
        stopped=false; 
        recorder.setAudioSource(MediaRecorder.AudioSource.MIC); 
        recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); 
        recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); 
        recorder.setOutputFile("/sdcard/sample.3gp"); 
        recorder.setMaxDuration(MAX_DURATION); 

        //Progressbar 
        pb.setMax(MAX_DURATION); 
        pb.setProgressTintList(ColorStateList.valueOf(Color.WHITE)); 

        new CountDownTimer(MAX_DURATION, 250) { 
         public void onTick(long millisUntilFinished) { 
          pb.setProgress(pb.getProgress() + 250); 
         } 
         public void onFinish() { 
         } 
        }.start(); 

Tout cela se passe dans une boîte de dialogue, alors comment puis-je effacer le contenu de la boîte de dialogue de sorte que la barre de progression remonte à sa valeur par défaut.

long timestamp = DateUtils.getCurrentTimeMillis(); 
    String imagePath = Environment.getExternalStorageDirectory() + "/testing/" + timestamp + "_D_FM_" + "John" + ".mp3"; 
    MediaRecorder mRecorder = new MediaRecorder(); 
mRecorder.setAudioSource(MediaRecorder.AudioSource.VOICE_RECOGNITION); mRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4); 
       mRecorder.setOutputFile(imagePath); 
       mRecorder.setAudioEncodingBitRate(16); 
       mRecorder.setAudioSamplingRate(44100); 
       mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC); 
       // Starting record time 
       recordTime = 0; 
       // Show TextView that displays record time 
       try { 
        mRecorder.prepare(); 
        mRecorder.start(); 
        // Change isRecroding flag to true 
        isRecording = true; 
        handler.post(UpdateRecordTime); 
       } catch (IOException e) { 
        FRLog.e("LOG_TAG", "prepare failed", e); 
       }
