如果我播放一个声音,它运行正常.

添加第二个声音会导致崩溃.

有人知道是什么原因造成的吗？

private SoundManager mSoundManager;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.sos);

    mSoundManager = new SoundManager();
    mSoundManager.initSounds(getBaseContext());

    mSoundManager.addSound(1,R.raw.dit);
    mSoundManager.addSound(1,R.raw.dah);

    Button SoundButton = (Button)findViewById(R.id.SoundButton);
    SoundButton.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            mSoundManager.playSound(1);
            mSoundManager.playSound(2);
        }
    });
}

我无法使用以下代码同时播放多个声音/哔声.在我的onclicklistener我已经加入:

public void onClick(View v) { 
     mSoundManager.playSound(1); 
     mSoundManager.playSound(2); 
} 

但是这一次只播放一个声音,声音索引为1,声音索引为2.

每当有onClick()事件时,如何使用此代码同时播放至少2个声音？

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(1, mSoundPool.load(mContext, SoundID, 1));
}

public void playSound(int index) { 

     int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); 
     mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, …
