我正在尝试在用户单击按钮时播放声音,如果我在活动打开的前 3-5 秒内单击按钮,效果很好,但是如果我等待超过 3-5 秒,则没有声音. 我也没有收到关于声音的任何错误....

任何想法都会被应用!

更新:这只发生在我的 HTC 上。如果我在三星 Galaxy S 2 上尝试它,它工作得很好!!!!

在我的 logcat 中说:“AudioHardwareQSD:AudioHardware pcm 播放将进入待机状态”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);}

这是我如何让它发挥作用的方法不是最好的,但它确实有效......

检查设备是否来自 HTC,然后创建一个播放声音的虚拟通知。您还必须确保您的文件是 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....}
