Android使用SoundPool播放短音效

前言

对于android播放一些简短音效，例如提示音，或者铃声，相对于使用mediaplayer，soundpool可以节省更多资源，并且可以同时播放多个音效，而且可以针对不同音效设置不同播放品质

实现

soundpool的具体作用，就不再阐述，直接贴代码

private soundpool.builder spbuilder;
private soundpool soundpool;
private integer[] fmsound = fmmanager.getrawaudios();

 if (build.version.sdk_int >= build.version_codes.lollipop) {
      if (null == spbuilder) {
        spbuilder = new soundpool.builder();
        audioattributes.builder builder = new audioattributes.builder();
        builder.setlegacystreamtype(audiomanager.stream_music);
        spbuilder.setaudioattributes(builder.build());
        spbuilder.setmaxstreams(10);
      }
      if (null == soundpool) {
        soundpool = spbuilder.build();
      }
    } else {
      if (null == soundpool) {
        soundpool = new soundpool(10, audiomanager.stream_music, 10); //最多播放10个音效，格式为steam_music，音质为10
      }
    }
    soundpool.setonloadcompletelistener(this);
    if (null == fmarray) {
      fmarray = new sparseintarray();
    }
    if (null == streamarray) {
      streamarray = new sparseintarray();
    }
    for (int i = 0; i < fmsound.length; i++) {
      fmarray.put(i + 1, soundpool.load(this, fmsound[i], 1));  //将需要播放的资源添加到soundpool中，并保存返回的streamid，通过streamid可以停止某个音效
    }


 private void playfmbyposition(int resultid) {
    if (null == soundpool || resultid < 0 || fmarray == null || fmarray.size() < 0 || streamarray == null)
      return;
    logutils.e(resultid + "------------" + fmarray.size());

    if (resultid < fmarray.size()) {
      if (!fmplaying.isplay(resultid)) {
        int fmplayid = soundpool.play(fmarray.get(resultid + 1), 1, 1, 0, -1, 1);
        streamarray.put(resultid, fmplayid);
        fmplaying.setplay(resultid, true);
      } else {
        soundpool.stop(streamarray.get(resultid));
        streamarray.removeat(resultid);
        fmplaying.setplay(resultid, false);
      }
    }
  }

  static class fmplaying {
    private static sparsebooleanarray playarray = new sparsebooleanarray();

    public static boolean isplay(int position) {
      return playarray.get(position, false);
    }

    public static void setplay(int position, boolean play) {
      playarray.put(position, play);
    }
}
