android - 在Android中顺序播放多种声音

Question

好吧，我的问题是我有大约12种声音和相同数量的图像。我想做的是播放带有相应图像的声音，当声音结束时，播放下一幅图像的下一个声音，依此类推，直到所有声音都播放完毕，我的意思是说，一个接一个地播放，并非全部相同时间。

它们都是短声音，所以我正在使用SoundPool。

有人可以帮我吗？先感谢您。

这是代码，对不起，我忘了包括它...

String[] flauta = new String[]{"flauta_do","flauta_re","flauta_mi","flauta_fa","flauta_sol","flauta_la","flauta_si","flauta_do_agudo","flauta_re_agudo","flauta_mi_agudo","flauta_fa_agudo","flauta_sol_agudo"};
String[] pentagrama = new String[]{"pentagrama_do","pentagrama_re","pentagrama_mi","pentagrama_fa","pentagrama_sol","pentagrama_la","pentagrama_si","pentagrama_do_agudo","pentagrama_re_agudo","pentagrama_mi_agudo","pentagrama_fa_agudo","pentagrama_sol_agudo"};
String[] nota = new String[]{"Do","Re","Mi","Fa","Sol","La","Si","Do alto","Re alto","Mi alto","Fa alto","Sol alto"};
String[] sonido = new String[]{"sonido_do","sonido_re","sonido_mi","sonido_fa","sonido_sol","sonido_la","sonido_si","sonido_do_agudo","sonido_re_agudo","sonido_mi_agudo","sonido_fa_agudo","sonido_sol_agudo"};

private SoundPool sPool;

ImageView flautaIV;
ImageView pentagramaIV;
TextView notaTV;

int resID = 0;
String recurso = "";
int sonidoNota = 0;



@Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_repasar);

        flautaIV = (ImageView)findViewById(R.id.flautaIV);
        pentagramaIV = (ImageView)findViewById(R.id.pentagramaIV);
        notaTV = (TextView)findViewById(R.id.notaTV);

        sPool = new SoundPool(1, AudioManager.STREAM_MUSIC, 0);


        for(int i = 0; i < flauta.length; i++)
        {
            recurso = flauta[i];

            resID = getResources().getIdentifier(recurso, "drawable", getPackageName());

            flautaIV.setImageResource(resID);

            recurso = pentagrama[i];

            resID = getResources().getIdentifier(recurso, "drawable", getPackageName());

            pentagramaIV.setImageResource(resID);

            notaTV.setText(nota[i]);

            recurso = sonido[i];

            resID = getResources().getIdentifier(recurso, "raw", getPackageName());

            sonidoNota = sPool.load(this, resID, 1);

            sPool.play(sonidoNota, (float)1.0, (float)1.0, 1, 0, 1f);

        }

    }

您没有指定，但我假设所有声音都在同时播放，大概吗？
SoundPool.play不会阻塞，因此它会立即环绕您的循环，加载下一个声音，然后播放。由于您已经使用SoundPool参数的1初始化了maxStreams，因此我不确定在尝试加载下一个流之前，您将获得什么样的行为。无论如何，您需要能够在play调用之后进行阻塞，直到流完成。据我所知，SoundPool没有该功能。我认为您将需要使用MediaPlayer，它允许您定义onCompletionListener。
