自定义列表框，可以调整高度。

我是用的自定义列表控件实现的。继承了CAknSingleStyleListBox。

//----------------------------------------------------注意事项------------------------------------------------

我终于找到解决的办法了。办法如下：
1.在创建列表元素的时候设置一下大小
       //数据操作
    iListShopBoxArray = new (ELeave) CDesCArrayFlat(10);
    CTextListBoxModel* model = iListShopBox->Model();
    model->SetItemTextArray(iListShopBoxArray);
    model->SetOwnershipType(ELbmOwnsItemArray);

    //添加滚动条
    iListShopBox->CreateScrollBarFrameL(ETrue);
    iListShopBox->ScrollBarFrame()->SetScrollBarVisibilityL(
            CEikScrollBarFrame::EOn, CEikScrollBarFrame::EAuto);

    //iListShopBox->SetItemHeightL(KListItemHieght);
    iListShopBox->SetFocus(ETrue);
    iListShopBox->MakeVisible(ETrue);
    iListShopBox->SetRect(iTList);
    //SetItemHeight()放到最后才有效，不知道是为什么……
    iListShopBox->View()->SetItemHeight(102);


2.在CreateItemDrawerL()中添加

void CMySingleStyleListBox::CreateItemDrawerL()
    {
    CColumnListBoxData* columnData = CColumnListBoxData::NewL();

    EnableDragEvents();

    const CFont* myFont;
    myFont = CEikonEnv::Static()->DenseFont();
    CEikListBox *aListBox = this;

    iItemDrawer = new (ELeave) CMyColumnListBoxItemDrawer(Model(), myFont,
            columnData, aListBox, iControl);

    iItemDrawer->SetItemCellSize(TSize(360, 102));
    }
就OK了……
