[J2ME之家-Symbian声音多媒体]使用CAknKeySoundSystem类将会在摄好像头捕获籣面的
时候播放声音方面是一个很有效的方法。下面的代码
演示了如何在你的应使用程序中实现这个特性：
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;

}

};

}
