[edit] 描述

S60第三版SDK并未提供给第三方程序一个方法来更换主题。但我们可以在

Extensions plug-in package for S60 3rd Edition SDK 获取到我们需要的API.


[edit] 解决方案

如何更换主题：

1、连接Skin Server

#include <AknSSrvClient.h> // link against aknskinsrv.lib
 
    RAknsSrvSession skinsSession;
 
    User::LeaveIfError( skinsSession.Connect( this ) );
 
    CleanupClosePushL( skinsSession );


2、获取当前skin的package ID

#include <centralrepository.h> // link against centralrepository.lib
 
 #include <AknSkinsInternalCRKeys.h>   
 
    void CMyThemeManager::StoreCurrentSkinIdL()
        {
 
        TAknsPkgIDBuf pidBuf;           
 
        CRepository* repository = CRepository::NewL(KCRUidPersonalisation );                   
 
        TInt retVal = repository->Get( KPslnActiveSkinUid, pidBuf );
 
        delete repository;
 
        repository = NULL;
 
        iOriginalSkinPid.SetFromDesL( pidBuf ); // iOriginalSkinPid is of type TAknsPkgID
 
        }


3、获得已安装skin packages列表

CArrayPtr<CAknsSrvSkinInformationPkg>* skinInfoArray =
 
                skinsSession.EnumerateSkinPackagesL();
 
CleanupStack::PushL( skinInfoArray );


4、查询已安装的主题，确认第一个有效新主题

TInt retValue( KErrNone );
 
    if ( skinInfoArray->Count() > 0 )
 
        {
 
        for ( TInt i = 0; i < skinInfoArray->Count(); i++ )
 
            {
 
            TAknsPkgID pkgId = skinInfoArray->At( i )->PID();
 
            if ( pkgId != iOriginalSkinPid )
 
                {
 
                // Activates a complete skin package
 
                retValue = skinsSession.SetAllDefinitionSets( pkgId );
 
                if ( retValue == KErrNone )
 
                    {
 
                    SetNewSkinIdL( pkgId );
 
                    }
 
                break;                   
 
                }
 
            }           
 
        }


5、在Central Repository中存储新主题id

void CMyThemeManager::SetNewSkinIdL( TAknsPkgID aPkgId )
 
        {
 
        TAknsPkgIDBuf pidBuf;           
 
        aPkgId.CopyToDes( pidBuf );
 
        CRepository* repository = CRepository::NewL( KCRUidPersonalisation );                   
 
        TInt retVal = repository->Set( KPslnActiveSkinUid, pidBuf );       
 
        // KPslnActiveSkinLocation value needs to be updated
 
        // if the new skin resides on memory card and the
 
        // previous one resided in phone memory (and vice versa)       
 
        delete repository;
 
        repository = NULL;
 
        }
