以前版本的只有修改style里面lv_style_scr的main_color和grad_color就可以了
void lv_style_init(void)
{
    /* Not White/Black/Gray colors are created by HSV model with
     * HUE = 210*/

    /*Screen style*/
    lv_style_scr.glass = 0;
    lv_style_scr.body.opa = LV_OPA_COVER;
    lv_style_scr.body.main_color = LV_COLOR_WHITE;
    lv_style_scr.body.grad_color = LV_COLOR_WHITE;
    lv_style_scr.body.radius = 0;
    lv_style_scr.body.padding.ver = LV_DPI / 12;
    lv_style_scr.body.padding.hor = LV_DPI / 12;
    lv_style_scr.body.padding.inner = LV_DPI / 12;

    lv_style_scr.body.border.color = LV_COLOR_BLACK;
    lv_style_scr.body.border.opa = LV_OPA_COVER;
    lv_style_scr.body.border.width = 0;
    lv_style_scr.body.border.part = LV_BORDER_FULL;
