在Symbian上播放聲音S60

Question

我非常喜歡Symbian，我無法播放聲音。我看了很多例子，我找不到我的錯誤。有沒有其他人有過這方面的經驗？任何方向都會有幫助。我用另一個班的計時器打電話給Play。

頭：

class TonePlayer : public CBase, public MMdaAudioPlayerCallback 
{ 
public: 
    static TonePlayer* NewL(); 
    static TonePlayer* NewLC(); 
    ~TonePlayer(); 

    void Play(); 
    void Stop(); 

protected: 
    TonePlayer(); 

    void MapcInitComplete(TInt aError, const TTimeIntervalMicroSeconds &aDuration); 
    void MapcPlayComplete(TInt aError); 

private: 
    CMdaAudioPlayerUtility* m_pAudioPlayer; 

    void ConstructL(); 
}; 

CPP：

TonePlayer* TonePlayer::NewL() 
{ 
    TonePlayer* self = NewLC(); 
    CleanupStack::Pop(self); 
    return self; 
} 

TonePlayer* TonePlayer::NewLC() 
{ 
    TonePlayer* self = new (ELeave) TonePlayer(); 
    CleanupStack::PushL(self); 
    self->ConstructL(); 
    return self; 
} 

TonePlayer::TonePlayer() 
{ 
} 

TonePlayer::~TonePlayer() 
{ 
    delete m_pAudioPlayer; 
    m_pAudioPlayer = NULL; 
} 

void TonePlayer::ConstructL() 
{ 
    m_pAudioPlayer = CMdaAudioPlayerUtility::NewL(*this); 
} 

void TonePlayer::MapcInitComplete(TInt aError, const TTimeIntervalMicroSeconds &aDuration) 
{ 
    MProEngEngine* pProfileEngine = ProEngFactory::NewEngineLC(); 
    MProEngProfile* pProfile = pProfileEngine->ActiveProfileL(); 
    MProEngTones& oTones = pProfile->ProfileTones(); 

    m_pAudioPlayer->OpenFileL(oTones.MessageAlertTone()); 
    m_pAudioPlayer->SetVolume(m_pAudioPlayer->MaxVolume()); 

    Play(); 

    delete pProfileEngine; 
} 

void TonePlayer::MapcPlayComplete(TInt aError) 
{ 
} 

void TonePlayer::Play() 
{ 
    m_pAudioPlayer->Play(); 
} 

void TonePlayer::Stop() 
{ 
    m_pAudioPlayer->Stop(); 
}

在諾基亞論壇的人在幫助我，這裏是最後的結果

TonePlayer* TonePlayer::NewL() 
{ 
    TonePlayer* self = NewLC(); 
    CleanupStack::Pop(self); 
    return self; 
} 

TonePlayer* TonePlayer::NewLC() 
{ 
    TonePlayer* self = new (ELeave) TonePlayer(); 
    CleanupStack::PushL(self); 
    self->ConstructL(); 
    return self; 
} 

TonePlayer::TonePlayer() 
{ 
} 

TonePlayer::~TonePlayer() 
{ 
    delete m_pAudioPlayer; 
    m_pAudioPlayer = NULL; 
} 

void TonePlayer::ConstructL() 
{ 
    MProEngEngine* pProfileEngine = ProEngFactory::NewEngineLC(); 
    MProEngProfile* pProfile = pProfileEngine->ActiveProfileLC(); 
    MProEngTones& oTones = pProfile->ProfileTones(); 

    m_pAudioPlayer = CMdaAudioPlayerUtility::NewFilePlayerL(oTones.MessageAlertTone(), *this); 

    CleanupStack::PopAndDestroy(2); 
} 

void TonePlayer::MapcInitComplete(TInt aError, const TTimeIntervalMicroSeconds &aDuration) 
{ 
    if(aError == KErrNone ) 
    { 
     m_pAudioPlayer->SetVolume(m_pAudioPlayer->MaxVolume()); 
    } 
} 

void TonePlayer::MapcPlayComplete(TInt aError) 
{ 
} 

void TonePlayer::Play() 
{ 

    m_pAudioPlayer->Play(); 
} 

void TonePlayer::Stop() 
{ 
    m_pAudioPlayer->Stop(); 
}
