SubLCD上状态栏消失

由于电池信息在更新电量信息时重画Status Icon Bar背景，将其他icon都覆盖掉，而后只画了电池图标，导致其他图片消失。
需要修改函数：

void SUBLCD_screens_hide_status_icons(void)

 {

 #ifdef __MMI_SUBLCD__

     /*----------------------------------------------------------------*/

     /* Local Variables                                                */

     /*----------------------------------------------------------------*/

     GDI_HANDLE act_lcd = GDI_ERROR_HANDLE;

     S32 x1, x2, y1, y2;

     /*----------------------------------------------------------------*/

     /* Code Body                                                      */

     /*----------------------------------------------------------------*/

 #ifdef __MMI_SUBLCD_SHOW_ANALOG_CLOCK__

     return;

 #endif 

     GDI_LOCK;

     gdi_lcd_get_active(&act_lcd);

     if (act_lcd != GDI_LCD_SUB_LCD_HANDLE)

     {

         UI_set_sub_LCD_graphics_context();

     }    

     wgui_status_icon_bar_get_clip(WGUI_STATUS_ICON_BAR_SUBLCD_H_BAR, &x1, &y1, &x2, &y2);

     wgui_status_icon_bar_show_sublcd_background(x1, y1, x2, y2, MMI_TRUE);

     if (act_lcd == GDI_LCD_MAIN_LCD_HANDLE)

     {

         UI_set_main_LCD_graphics_context();

     }

     GDI_UNLOCK;

 #endif /* __MMI_SUBLCD__ */ 

 }
