Playing audio files one after another

Question

I have a list of audio files like this,

int music_numbers[] = { R.raw.one, R.raw.two, R.raw.three, R.raw.four,
            R.raw.five, R.raw.six, R.raw.seve         


        

Answer 1

Use a queue for holding the numbers to be played.

private void _play_numbers(final String i) {
    // e.g '100': put '1', '0', '0' in a Queue after converting to digits
    Queue queue = new LinkedList();
    //Use the add method to add items.

    myDigit = // remove next digit from queue..

    _function_play_file(myDigit);
}

void _function_play_file(int files) {
     switch(files) {
       case 0:
        mPlayer = MediaPlayer.create(PlayFileActivity.this, R.raw.payment);
        mPlayer.setOnCompletionListener(completeListener );
        mPlayer.start();
        break;
 .....
 }

OnCompletionListener completeListener = new OnCompletionListener() {

    @Override
    public void onCompletion(MediaPlayer mp) {
        mp.release();
        myDigit = // remove next digit from queue..
        if (myDigit != -1)  // if queue is not empty..
            _function_play_file(myDigit);
    }
});

}
