SoundPool不播放声音
问题描述:
我做了一个SoundManager类,它使用SoundPool函数来循环播放特定的声音,但是我无法弄清楚它为什么不播放声音。SoundPool不播放声音
public class SoundManager {
private SoundPool mSoundPool;
private HashMap<Integer, Integer> mSoundPoolMap;
private AudioManager mAudioManager;
private Context mContext;
public SoundManager()
{
}
public void initSounds(Context theContext) {
mContext = theContext;
mSoundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0);
mSoundPoolMap = new HashMap<Integer, Integer>();
mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);
}
public void addSound(int Index, int SoundID) {
mSoundPoolMap.put(Index, mSoundPool.load(mContext, SoundID, 1));
}
public void playSound(int index) {
int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, 0, 1f);
}
public void playLoopedSound(int index) {
int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, -1, 1f);
}
}
该类正从我的活动可以通过名为:
private SoundManager mSoundManager;
mSoundManager = new SoundManager();
mSoundManager.initSounds(getBaseContext());
mSoundManager.addSound(1, R.raw.sound);
mSoundManager.playSound(1);

显然,这是行不通的onCreate我的活动,但称这是当一个事件发生(意图/按键时)它似乎工作
答
我有这个问题,并最终通过在支持音频的模拟器上运行解决它!
简直不敢相信!
