如何从声音中播放数组？- 安卓

我创建了Array声音，然后需要播放它们，但是我只能听到第一个声音：

这是我的Array：

public static class Marrays{
    public static String[] Zero(){
        String[] OK = new String[] {"num1.mp3" , "increment.amr", "num1.mp3"};
        return OK;
    }
}

和：

String[] a = Marrays.Zero();

我从上面使用array：

for (int i = 0; i < a.length; i++) {
    try {
        AssetFileDescriptor afd = getAssets().openFd(a[i]);
        mediaPlayer.stop();
        mediaPlayer.release();
        mediaPlayer = new MediaPlayer();
        mediaPlayer.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(),afd.getLength());
        mediaPlayer.prepare();
        mediaPlayer.start();
    } 
    catch (IllegalArgumentException e) {  Toast.makeText(getApplicationContext(), e.toString() , Toast.LENGTH_SHORT).show();  } 
    catch (IllegalStateException e) {Toast.makeText(getApplicationContext(), e.toString() , Toast.LENGTH_SHORT).show(); } 
    catch (IOException e) { Toast.makeText(getApplicationContext(), e.toString() , Toast.LENGTH_SHORT).show();}
}

机管局

看到这个：

if(count < 3){
    Main_Sound_mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {

        @Override
        public void onCompletion(MediaPlayer mp) {
            if(count <= 3){
            try {
                AssetFileDescriptor afd = getAssets().openFd(a[count]);
                if (Main_Sound_mediaPlayer.isPlaying()==true ){
                    Main_Sound_mediaPlayer.stop();}
                Main_Sound_mediaPlayer.reset();
                Main_Sound_mediaPlayer.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(),afd .getLength());
                Main_Sound_mediaPlayer.prepare();
                Main_Sound_mediaPlayer.start();
            } 
            catch (IllegalArgumentException e) {  Toast.makeText(getApplicationContext(), e.toString() , Toast.LENGTH_SHORT).show();  } 
            catch (IllegalStateException e) {Toast.makeText(getApplicationContext(), e.toString() , Toast.LENGTH_SHORT).show(); } 
            catch (IOException e) { Toast.makeText(getApplicationContext(), e.toString() , Toast.LENGTH_SHORT).show();}
            }
            count++ ;
        }
    });
    if (flag == true) {
        try {
            AssetFileDescriptor afd = getAssets().openFd(a[count]);
            if (Main_Sound_mediaPlayer.isPlaying()==true ){
                Main_Sound_mediaPlayer.stop();}
            Main_Sound_mediaPlayer.reset();
            Main_Sound_mediaPlayer.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(),afd.getLength());
            Main_Sound_mediaPlayer.prepare();
            Main_Sound_mediaPlayer.start();
        } 
        catch (IllegalArgumentException e) {  Toast.makeText(getApplicationContext(), e.toString() , Toast.LENGTH_SHORT).show();  } 
        catch (IllegalStateException e) {Toast.makeText(getApplicationContext(), e.toString() , Toast.LENGTH_SHORT).show(); } 
        catch (IOException e) { Toast.makeText(getApplicationContext(), e.toString() , Toast.LENGTH_SHORT).show();}
        flag = false;
    }
    count++ ;
}else {
    if (Main_Sound_mediaPlayer.isPlaying()==true ){
        Main_Sound_mediaPlayer.stop();}
    Main_Sound_mediaPlayer.reset();
}
