问题是下面这样的解决的办法就是

以前在AppUI里面的的 ConstructL是这样的BaseConstructL();只要声明假如背景就可以BaseConstructL(EAknEnableSkin);

关于form 的背景不是系统的问题

我想出现的效果是就是主题背景上面有form 但是出现的效果里面是没有背景的后面是白色的底色不知道那里的问题:

我用symbian 的form 编写录入程序资源文件这样:
我想要的效果:

我做出来的效果:

RESOURCE DIALOG r_myform_form_dialog
{
flags =  EEikDialogFlagFillAppClientRect |
//EEikDialogFlagNoDrag |
         EEikDialogFlagNoTitleBar |// EEikDialogFlagNoBorder |
         EEikDialogFlagCbaButtons;
buttons = R_AVKON_SOFTKEYS_OPTIONS_BACK;
form = r_aknexform_text_field_form;
}

//-----------------------------------------------------------------------------
//
// r_aknexform_text_field_form
// Standard for Form. there are two text fields.
//
//-----------------------------------------------------------------------------
//
RESOURCE FORM r_aknexform_text_field_form
{
flags =  EEikFormUseDoubleSpacedFormat|EEikFormEditModeOnly ;
items =
      {
      DLG_LINE
         {
         type = EEikCtEdwin;
         prompt = qtn_aknexform_form_label_ed1;
         id = EmyformDlgCIdEdwin;
         itemflags = EEikDlgItemTakesEnterKey | EEikDlgItemOfferAllHotKeys;
         control = EDWIN
            {
            flags = EEikEdwinNoHorizScrolling | EEikEdwinResizable;
            width = AKNEXFORM_EDWIN_WIDTH;
            lines = AKNEXFORM_EDWIN_LINES;
            maxlength = 50;
            // added to limit expanding in forms.
            // If you want full screen use 5 here
            max_view_height_in_lines = 5;
            // if you have the line above, you must have this.
            // It's calculable from LAF
            base_line_delta = 21;
            };
         },
      DLG_LINE
         {
         type = EEikCtEdwin;
         prompt = qtn_aknexform_form_label_ed2;
         id = EmyformDlgCIdEdwin2;
         itemflags = EEikDlgItemTakesEnterKey | EEikDlgItemOfferAllHotKeys;
         control = EDWIN
            {
            flags = EEikEdwinNoHorizScrolling | EEikEdwinResizable;
            width = AKNEXFORM_EDWIN_WIDTH;
            lines = AKNEXFORM_EDWIN_LINES;
            maxlength = 50;
            // added to limit expanding in forms.
            // If you want full screen use 5 here
            max_view_height_in_lines = 5;
            // if you have the line above, you must have this.
            // It's calculable from LAF
            base_line_delta = 21;
            };
         }
      };
}

类的实现这样:

#include "ZFirst_Login_Form.h"

CZFirst_Login_Form* CZFirst_Login_Form::NewL()
      {
      CZFirst_Login_Form* self = new ( ELeave ) CZFirst_Login_Form();
CleanupStack::PushL( self );
self->ConstructL();
CleanupStack::Pop();
return self;
      }

CZFirst_Login_Form::~CZFirst_Login_Form()
      {
      }
CZFirst_Login_Form::CZFirst_Login_Form()
      {
      // No implementation required
      }

void CZFirst_Login_Form::ConstructL()
      {
      CAknForm::ConstructL();
      }
TInt CZFirst_Login_Form::ExecuteLD( TInt aResourceId )
      {
iCurrentId = aResourceId;

return CAknForm::ExecuteLD( aResourceId );
      }
void CZFirst_Login_Form::PrepareLC( TInt aResourceId )
      {
iCurrentId = aResourceId;

CAknForm::PrepareLC( aResourceId );
      }
//保存数据
TBool CZFirst_Login_Form::SaveFormDataL()
      {
      return ETrue;
      }
//不保存表单数据。
void CZFirst_Login_Form::DoNotSaveFormDataL()
      {

      }

//给成员数据设置默认值
void CZFirst_Login_Form::PostLayoutDynInitL()
      {
      CAknForm::PostLayoutDynInitL();
      }

//显示保存查询。如果用户回答“不”，此查询返回字段值为编辑前的值。
//编辑模式下这就是所谓的后台功键 back
TBool CZFirst_Login_Form::QuerySaveChangesL()
      {
TBool isAnsYes( CAknForm::QuerySaveChangesL() );

if ( isAnsYes )
      {
      SaveFormDataL();
      }
else
      {
      // Case that answer "No" to query.
      DoNotSaveFormDataL();
      }

return isAnsYes;
      }
调用在form中这样:
CZFirst_Login_Form* iform = CZFirst_Login_Form ::NewL();
TInt ret = iform->ExecuteLD( aResourceId );
