如何循环播放原始文件夹中的mp3文件列表

Question

I have many Sound Files (.MP3) in res/raw folder. I want to play each file one by one.

Here is my code

int [] resID ={ R.raw.s1,R.raw.s2,R.raw.s3,R.raw.s4,R.raw.s5};

ArrayList<Integer> indexForMusic; 

 ..........................

 ..........................

 // on click of play button

public void playMusic(View v)
{
    for(int i:indexForMusic)
    {
        MediaPlayer  mediaPlayer=MediaPlayer.create(this,resID[i]);
        mediaPlayer.start();
        try 
        {
             wait(1000);
        }
        catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

but the problem is that all MP3 files are getting played simultanously, and there is no delay beteew the playing of files..

Please tell me how can i play music one after the other? putting wait() inside for loop is throwing an exception.

Answer 1

Try thread, something like following

    Thread T=new Thread(new runnable(){
    public void run(){
     MediaPlayer  mediaPlayer=MediaPlayer.create(this,resID[i]);
            mediaPlayer.start();
            try 
            {
                 sleep(1000);
            }
            catch (InterruptedException e) {
                e.printStackTrace();
            }

    }

    }
   );
    T.start();

simultaneously*, or try CountDownTimer

new CountDownTimer(1000, 100) 
{

public void onTick(long millisUntilFinished) {

                                     }
public void onFinish() {
    mediaPlayer.start();
}
}.start();
