我无法使用以下代码同时播放多个声音/哔声。在我的onclicklistener
我添加了:
public void onClick(View v) {
mSoundManager.playSound(1);
mSoundManager.playSound(2);
}
但这一次只播放一个声音,索引为1的声音后跟索引2的声音。
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, 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);
}
}

让以下课程使用声音池播放声音fx:
public class SoundManager {
public static int SOUNDPOOLSND_MENU_BTN = 0;
public static int SOUNDPOOLSND_WIN = 1;
public static int SOUNDPOOLSND_LOOSE = 2;
public static int SOUNDPOOLSND_DRAW = 3;
public static int SOUNDPOOLSND_TICK1 = 4;
public static int SOUNDPOOLSND_TICK2 = 5;
public static int SOUNDPOOLSND_OUT_OF_TIME = 6;
public static int SOUNDPOOLSND_HISCORE = 7;
public static int SOUNDPOOLSND_CORRECT_LETTER = 8;
public static boolean isSoundTurnedOff;
private static SoundManager mSoundManager;
private SoundPool mSoundPool;
private SparseArray <Integer> mSoundPoolMap;
private AudioManager mAudioManager;
public static final int maxSounds = 4;
public static SoundManager getInstance(Context context)
{
if (mSoundManager == null){
mSoundManager = new SoundManager(context);
}
return mSoundManager;
}
public SoundManager(Context mContext)
{
mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);
mSoundPool = new SoundPool(maxSounds, AudioManager.STREAM_MUSIC, 0);
// mSoundPool.setOnLoadCompleteListener(new OnLoadCompleteListener() {
// public void onLoadComplete(SoundPool soundPool, int sampleId,int status) {
// loaded = true;
// }
// });
mSoundPoolMap = new SparseArray<Integer>();
mSoundPoolMap.put(SOUNDPOOLSND_MENU_BTN, mSoundPool.load(mContext, R.raw.menubutton, 1));
mSoundPoolMap.put(SOUNDPOOLSND_WIN, mSoundPool.load(mContext, R.raw.win, 1));
mSoundPoolMap.put(SOUNDPOOLSND_LOOSE, mSoundPool.load(mContext, R.raw.lose, 1));
mSoundPoolMap.put(SOUNDPOOLSND_TICK1, mSoundPool.load(mContext, R.raw.tick_0, 1));
mSoundPoolMap.put(SOUNDPOOLSND_TICK2, mSoundPool.load(mContext, R.raw.tick_1, 1));
mSoundPoolMap.put(SOUNDPOOLSND_OUT_OF_TIME, mSoundPool.load(mContext, R.raw.out_of_time, 1));
mSoundPoolMap.put(SOUNDPOOLSND_HISCORE, mSoundPool.load(mContext, R.raw.personal_highscore, 1));
mSoundPoolMap.put(SOUNDPOOLSND_CORRECT_LETTER, mSoundPool.load(mContext, R.raw.correct_letter, 1));
// testing simultaneous playing
int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
mSoundPool.play(mSoundPoolMap.get(0), streamVolume, streamVolume, 1, 20, 1f);
mSoundPool.play(mSoundPoolMap.get(1), streamVolume, streamVolume, 1, 2, 1f);
mSoundPool.play(mSoundPoolMap.get(2), streamVolume, streamVolume, 1, 0, 1f);
}
public void playSound(int index) {
if (isSoundTurnedOff)
return;
int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, 0, 1f);
}
public static void clear()
{
if (mSoundManager != null){
mSoundManager.mSoundPool = null;
mSoundManager.mAudioManager = null;
mSoundManager.mSoundPoolMap = null;
}
mSoundManager = null;
}
}
它同时播放评论“同时播放测试”下面提到的3种声音。看来你需要在我的代码监听器(OnLoadCompleteListener
)中实现注释。可能会发生系统只是在你开始播放时没有加载声音。如果您不想实现提到的侦听器,请在播放声音活动开始后等待一段时间,并在一段时间后开始播放声音。
