android – SoundPool没有播放声音

我创建了一个SoundManager类,它使用SoundPool函数来循环特定的声音,但我无法弄清楚为什么它没有播放声音.

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); 
}

}

这个类是通过我的Activity来调用的：

private SoundManager mSoundManager;
mSoundManager = new SoundManager();
mSoundManager.initSounds(getBaseContext());
mSoundManager.addSound(1, R.raw.sound);
mSoundManager.playSound(1);

解决方法:

显然它对我的活动不起作用,但在事件发生时调用它(Intents / Keypress)它似乎工作
