使用摄像头拍照的时候添加一个快门的声音

Code:

// myapp.h

#include <aknsoundsystem.h>

const TInt KSnapSoundId = 2;

class MyClass

{

...

private:

CAknKeySoundSystem* iCameraSound;

};

void MyClass::ConstructL()

{

...

iCameraSound =

   static_cast<CAknAppUi*>(CEikonEnv::Static()->AppUi())->KeySounds();

    if (iCameraSound)

        {

        TRAPD(error, iCameraSound->AddAppSoundInfoListL(

              R_CAMERA_SNAP_SOUND));

        if ((error != KErrAlreadyExists) && (error != KErrNone))

            {

            User::LeaveIfError(error);

            }

        }

}

void MyClass::PlaySnapSound()

{

iCameraSound->PlaySound(KSnapSoundId);

}

在你的.RSS资源文件中添加下面的代码

Code:

#define KcameraSoundFile

    "Z:\\system\\sounds\\digital\\Camera1a_2_8kHz.wav"

#define KSnapSoundId 2

RESOURCE AVKON_SOUND_INFO_LIST r_camera_snap_sound

    {

    list =

         {

        AVKON_SOUND_INFO

           {

            sid = KSnapSoundId;

            priority = 45;

            preference = EAknAudioPrefCamera; // defined in avkon.hrh

            file = KCameraSoundFile;

            }

        };

    }
