Question

我试图在用户点击按钮时发出声音，如果我在活动打开的前3-5秒点击按钮，那么效果很好但是如果我等了3-5秒那么没声音。我也没有收到关于声音的任何错误....

任何想法都会受到欢迎！

更新：这只发生在我的HTC上。如果我在三星Galaxy S 2上尝试这个，它可以正常工作!!!!

在我的logcat中说：“AudioHardwareQSD：AudioHardware pcm播放将进入待机状态”这个任何解决方法???

@Override
protected void onCreate(Bundle savedInstanceState)
{

    mSoundPoolMap = new HashMap<Integer, Integer>();
    mSoundPool = new SoundPool(16, AudioManager.STREAM_RING, 0);
    mAudioManager= (AudioManager) mcontext.getSystemService(Context.AUDIO_SERVICE);

    mSoundPoolMap.put(1, mSoundPool.load(mcontext, R.raw.tap, 1));}



       @Override
        public void onClick(View v)
        {   
            float streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_RING);
            streamVolume = streamVolume / mAudioManager.getStreamMaxVolume(AudioManager.STREAM_RING);
            mSoundPool.play(mSoundPoolMap.get(1), streamVolume, streamVolume, 1, 0, 1);}

以下是我如何使这项工作不是最好的，但它有效...

检查设备是否来自HTC，然后创建播放声音的虚拟通知。另外，你必须确保你的文件是MP3而不是wav或OGG ......

public static void playSound(int index)
{

    String m_strManufacture = Build.MANUFACTURER;
    Log.i(TAG, "Device Name: " + m_strManufacture);
    if (m_strManufacture.equals("HTC"))
    {


        NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = new Notification();
        Intent notificationIntent = new Intent(mContext, mContext.getClass());
        // set intent so it does not start a new activity
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
        // PendingIntent intent = PendingIntent.getActivity(mContext, 0, notificationIntent, 0);
        // mContext.getResources().getResourceName(R.raw.ringer);
        notification.sound = Uri.parse("android.resource://com.yourpackages/raw/" + sound);
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        notificationManager.notify(0, notification);

    }
    else {//Do the soundpool work....}

打开我的活动3秒后SoundPool没有播放
