如何在佈局中播放按鈕的聲音onclick？

Question

我有一個佈局，其中多個按鈕的按鈕一個聲音播放respectively.My代碼showing.onclick就像但它不起作用： -

@Override 
public void onClick(View view) { 
    resetPlayer(); 
    int index = 0; 
    if (view.equals(objbutton1)) 
     index = R.raw.sound1; 

    while (true) { 
     this.objplayer = MediaPlayer.create(this, index); 
     this.objplayer.setLooping(false); 
     this.objplayer.start(); 
     this.objplayer 
       .setOnCompletionListener(new MediaPlayer.OnCompletionListener() { 
        @Override 
        public void onCompletion(MediaPlayer mp) { 
         MainActivity.this.objplayer.release(); 
         MainActivity.this.objplayer = null; 

        } 
       } 
       ); 
     if(view.equals(objbutton2)) 
     { 
      index=R.raw.sound2; 
      continue; 

     } 
     if(view.equals(objbutton3)) 
     { 
      index=R.raw.sound3; 
      continue; 

     } 
     if(view.equals(objbutton4)) 
     { 
      index=R.raw.sound4; 
      continue; 

     } 
     if(view.equals(objbutton5)) 
     { 
      index=R.raw.sound5; 
      continue; 

     } 
     break; 
    } 

} 

private void resetPlayer() { 
    if (this.objplayer != null) { 
     if (this.objplayer.isPlaying()) 
      this.objplayer.stop(); 
     this.objplayer.release(); 
     this.objplayer = null; 
    } 

應用程序是隻打了一個聲音，當點擊另一個按鈕沒有健全的改變

使用此

MediaPlayer mp = MediaPlayer.create(getApplicationContext(), index); 
        mp.start(); 

像...

private MediaPlayer mp; // declare it in public area. 

    public void onClick(View view) { 
    int index = 0; 
    if (view.equals(objbutton1)){ 
     index = R.raw.sound1; 
      if(mp !=null && mp.isPlaying()) mp.stop(); 
     mp = MediaPlayer.create(getApplicationContext(), index); 
      mp.start(); 
     } 
     if(view.equals(objbutton2)) 
     { 
      index=R.raw.sound2; 
      if(mp !=null && mp.isPlaying()) mp.stop(); 
     mp = MediaPlayer.create(getApplicationContext(), index); 
      mp.start(); 
     } 
     if(view.equals(objbutton3)) 
     { 
      index=R.raw.sound3; 
      if(mp !=null && mp.isPlaying()) mp.stop(); 
      mp = MediaPlayer.create(getApplicationContext(), index); 
     mp.start(); 
     } 
     if(view.equals(objbutton4)) 
     { 
      index=R.raw.sound4; 
      if(mp !=null && mp.isPlaying()) mp.stop(); 
      mp = MediaPlayer.create(getApplicationContext(), index); 
     mp.start(); 
     } 
     if(view.equals(objbutton5)) 
     { 
      index=R.raw.sound5 
      if(mp !=null && mp.isPlaying()) mp.stop(); 
     mp = MediaPlayer.create(getApplicationContext(), index); 
     mp.start(); 
     } 
} 

並在onDestroy()把這個mp.release();
