大部分游戏都有音效，不然游戏乐趣会降低很多，而几乎所有音效都是重复播放的。
下面的代码只加载一次音频文件，但是却可以被多次使用。请将音频文件放置在/res/raw路径中。

public static final int SOUND_EXPLOSION = 1;

private HashMap soundPoolMap;

private void initSounds() {
     soundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 100);
     soundPoolMap = new HashMap();
     soundPoolMap.put(SOUND_EXPLOSION, soundPool.load(getContext(), R.raw.explosion, 1));
}

public void playSound(int sound) {
   
    AudioManager mgr = (AudioManager)getContext().getSystemService(Context.AUDIO_SERVICE);
    float streamVolumeCurrent = mgr.getStreamVolume(AudioManager.STREAM_MUSIC);
    float streamVolumeMax = mgr.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
