TD 加载界面实现

一）编写ini文件，用button实现加载界面

cl_animationWin={
  type="window"
  x=0
  y=0
  w=1024
  h=600
  style="cl_normalwin"
  flags={
    window_splash
  }

...

  cl_picLoadingButton={
    type="button"
    x=425
    y=180
    w=174
    h=174
    style="comWaitBtn"
    flags={
      no_focus
      button_no_offset
      no_event
    }
  }
...
}

二）代码中实现此功能

static void initCarLifeAnimation()
{
    TWidget *loading,*aniLogo;

    loading = TObjectGetFromName("cl_picLoadingButton");
    aniLogo = TObjectGetFromName("cl_picLoadingLogo");

    TTable *tableLoading = TTableCreate();
    TTable *tableLogo = TTableCreate();

    int i = 0;
    char picPath[ANI_PICPATH_CHARMAX]= {0};
    for(i=0; i<ANI_LOADING_PIC_MAX; i++)
    {
        sprintf(picPath,"../style/carlife/car_ic_loading_%02d.png",i+1);

        CL_D("----add %d%s 
",i,picPath);
        TTableAddString(tableLoading,(Tint)NULL,picPath,-1);
        memset(picPath,0,ANI_PICPATH_CHARMAX);
    }

    for(i = 0; i<ANI_LOGO_PIC_MAX; i++)
    {
        sprintf(picPath,"../style/carlife/car_ic_loading_logo%02d.png",i+1);
        CL_D("----add %d %s 
",i,picPath);
        TTableAddString(tableLogo,(Tint)NULL,picPath,-1);
        memset(picPath,0,ANI_PICPATH_CHARMAX);
    }

    if(clViewInfo&&clViewInfo->animationInfo)
    {
        if(clViewInfo->animationInfo->btnAniLogo==NULL)
        {
            clViewInfo->animationInfo->btnAniLogo = createBtnAnimation(aniLogo,tableLogo,ANI_TIME_INT,1);
            registerAniBtnFinishCBK(clViewInfo->animationInfo->btnAniLogo,animationLogoFinished,animationShowLogo);
        }
        else
        {
            CL_E("[error] last logo animtion hasn't destory.plz check.
");
        }

        if(clViewInfo->animationInfo->btnAni==NULL)
        {
            clViewInfo->animationInfo->btnAni = createBtnAnimation(loading,tableLoading,ANI_TIME_INT,-1);
            registerAniBtnFinishCBK(clViewInfo->animationInfo->btnAni,animationLogoFinished,NULL);
            startBtnAnimation(clViewInfo->animationInfo->btnAni);
        }
        else
        {
            CL_E("[error] last loading animtion hasn't destory.plz check.
");
        }

    }

    TTableDestroy(tableLoading);
    TTableDestroy(tableLogo);

}

三）开始加载界面  startBtnAnimation

四）暂停加载界面 stopBtnAnimation

五）实现回调函数

animationShowLogo

static void animationShowLogo(TWidget *widget)
{
    TWidget *btn = TObjectGetFromName("cl_picBaiduLabel");
    TwShow(btn);
}

animationLogoFinished

static void animationLogoFinished(TWidget *widget)
{
    CHECK_POINTER(clViewInfo);

    TWidget *loading = TObjectGetFromName("cl_picLoadingButton");

    CL_D("%s %d widget %x:laoding %x
",__FUNCTION__,__LINE__,(Tuint32)widget,(Tuint32)loading);

    if(loading == widget)
    {
        CL_I();

        TWidget *btn = TObjectGetFromName("cl_picLoadLogo");
        TwHide(btn);
        btn = TObjectGetFromName("cl_picLoadingButton");
        TwHide(btn);
        btn = TObjectGetFromName("cl_picLoadingLabel");
        TwHide(btn);

        btn = TObjectGetFromName("cl_picLoadingLogo");
        TwShow(btn);

        if(clViewInfo->animationInfo->btnAniLogo)
        {
            startBtnAnimation(clViewInfo->animationInfo->btnAniLogo);
        }
    }
    else
    {
        if(clViewInfo->isProjected == TRUE)
        {
            clViewInfo->isProjected = FALSE;
            changeView(CL_PROJECTED);
        }
        else
        {
            changeView(CL_Failed);
        }
    }
}
