Porgress Bar läuft schneller auf jedem onClick

Question

Ich versuche, einen einfachen Audio-Recorder zu machen. Das Problem mit dem Audiorekorder ist, dass jedes Mal, wenn der Fortschrittsbalken schneller wird. Es würde in der ersten Runde gut laufen, aber wenn Sie den Ton abbrechen und das zweite Mal gehen wollen, wird es schneller.

 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(); 

All dies wird in einem Dialog geschieht, so wie kann ich den Inhalt des Dialogs löschen, so dass die Fortschrittsbalken auf den Standardwert zurückgehen.

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);

Wenn Klick Audio-Wiedergabe:
