Seekbar progress timer Mp3 android

Question

J'ai un lecteur multimédia qui utilise une barre de recherche pour jouer de la chanson. Lorsque la chanson est en cours de lecture, je veux mettre la durée de la chanson à 30 secondes et mettre en pause la lecture. Mon problème est que j'ai mis en place une minuterie pour la durée de la chanson. par exemple. commence à 00: 00,00: 01,00: 02,00: 03 ... 00.10 ... 00.13, 00:29, 0:30 mais la minuterie s'affiche.

How can i make it display 00:00,00:01,00:02,00:03... 00.10...00.13, 00:29, to 00:30 only. 

Voici mon setOnSeekBarChangeListener pour la barre de recherche

 sbMusicProgress.setOnSeekBarCh 

angeListener(new SeekBar.OnSeekBarChangeListener() { 

       @Override 
       public void onStopTrackingTouch(SeekBar arg0) { 
       // TODO Auto-generated method stub 
        System.out.println("maxvolume"+Integer.toString(maxVolume)); 
       } 

       @Override 
       public void onStartTrackingTouch(SeekBar arg0) { 
       // TODO Auto-generated method stub 
       } 

       @Override 
       public void onProgressChanged(SeekBar arg0, int progress, boolean arg2) { 
       // TODO Auto-generated method stub 

        if (mp!=null){ 

         mp.seekTo(progress); 
         sbMusicProgress.setProgress(progress); 
         System.out.println("progress: "+ progress); 

         //context.txMp3Prog.setText("00:"+String.valueOf(progress)); 
         context.txMp3Prog.setText("00:"+String.valueOf(progress)); 

    }}.. 

Answer 1

vous devez convertir millisecods en secondes utilisés comme ci-dessous fonction: première méthode d'ajout de votre classe d'activité:

public String milliSecondsToTimer(long milliseconds){ 
     String finalTimerString = ""; 
     String secondsString = ""; 

     // Convert total duration into time 
      int hours = (int)(milliseconds/(1000*60*60)); 
      int minutes = (int)(milliseconds % (1000*60*60))/(1000*60); 
      int seconds = (int) ((milliseconds % (1000*60*60)) % (1000*60)/1000); 
      // Add hours if there 
      if(hours > 0){ 
       finalTimerString = hours + ":"; 
      } 

      // Prepending 0 to seconds if it is one digit 
      if(seconds < 10){ 
       secondsString = "0" + seconds; 
      }else{ 
       secondsString = "" + seconds;} 

      finalTimerString = finalTimerString + minutes + ":" + secondsString; 

     // return timer string 
     return finalTimerString; 
    } 

et utiliser la méthode comme ci-dessous:

context.txMp3Prog.setText(milliSecondsToTimer(progress)); 

et il est utilisé cette méthode si la durée du lecteur mp3 supérieure minutes montre comme- 01:00,01:01.......

Answer 2

votre variable progress est exprimé en millisecondes. Vous pouvez le convertir en secondes en le divisant par 1000.

context.txMp3Prog.setText("00:" + String.valueOf(progress/1000));
