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 SoundPool soundPool;
private HashMap<Integer, Integer>soundPoolMap;
private void initSounds() {
soundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 100);
soundPoolMap = new HashMap<Integer,Integer>();
soundPoolMap.put(SOUND_EXPLOSION, soundPool.load(getContext(),R.raw.explosion, 1));
}
public void playSound(int sound) {
AudioManagermgr =(AudioManager)getContext().getSystemService(Context.AUDIO_SERVICE);
floatstreamVolumeCurrent =mgr.getStreamVolume(AudioManager.STREAM_MUSIC);
floatstreamVolumeMax =mgr.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
float volume= streamVolumeCurrent / streamVolumeMax;
soundPool.play(soundPoolMap.get(sound), volume, volume, 1, 0,1f);
}
public void explode() {
playSound(SOUND_EXPLOSION);
}
