我试图在用户点击按钮时播放声音,如果我在活动打开的前3-5秒内点击按钮,效果很好,但是如果我等待超过3-5秒就没有声音了。我也没有收到任何关于声音的错误...
任何想法都会得到重视!
更新:这只发生在我的HTC上。如果我在三星Galaxy S 2上试一下,它工作正常!
在我的日志中写着:"AudioHardwareQSD: AudioHardware pcm播放将进入待机状态“有没有解决这个问题的办法?
@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);}发布于 2012-09-05 17:41:17
以下是我是如何让它工作的,虽然不是最好的,但它确实有效。
已检查设备是否来自HTC,然后创建了一个播放声音的虚拟通知。此外,您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);
}
