Sound轻量级播放声音资源首选（只能加载本地声音，网络声音使用MediaPlayer）

核心：注意，SoundPool 调用play方法才会有声音

private SoundPool soundPool=new SoundPool.Builder().setMaxStreams(6).build();
 int load = soundPool.load("本地音频路径", 1);
 soundPool.play(load,  1.0f, 1.0f, 1, 0, 1.0f);

        int id = 0;
        try {
    
    
            File f = new File(path);
            ParcelFileDescriptor fd = ParcelFileDescriptor.open(f,
                    ParcelFileDescriptor.MODE_READ_ONLY);
            if (fd != null) {
    
    
                id = _load(fd.getFileDescriptor(), 0, f.length(), priority);
                fd.close();
            }
        } catch (java.io.IOException e) {
    
    
            Log.e(TAG, "error loading " + path);
        }
        return id;

MediaPlayer的基本使用：点击播放，再点击停止播放，再点击重新播放

 private MediaPlayer mediaPlayer= new MediaPlayer();;

 if (animations.isRunning()&& mediaPlayer.isPlaying()) {
    
    
                        animations.stop();
                        mediaPlayer.stop();


                    } else {
    
    
                        animations.start();
                        String url = data.get(position).getSoundMsgDto().getUrl();
                        Log.e("wy", "onClick url: "+url );
                        if(url.contains("http")){
    
    
//                             load = soundPool.load(url, 1);
                            try {
    
    
                                mediaPlayer.reset();
                                mediaPlayer.setDataSource(url);
                                mediaPlayer.prepare();
                                mediaPlayer.start();
                            } catch (Exception e) {

                            }
                        }else {

                                mediaPlayer.prepare();
                                mediaPlayer.start();
                            } catch (Exception e) {
    
    
                                e.printStackTrace();
