Code to reproduce

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

char bgbuf[32];
void test_btn_on_img(void)

{

    static lv_style_t style;

    lv_scr_load(lv_scr_act());

    lv_style_init(&style);

   // lv_style_set_bg_color(&style, lv_palette_main(LV_PALETTE_YELLOW));

    lv_style_set_bg_opa(&style, LV_OPA_COVER);

    lv_style_set_width(&style, LV_HOR_RES);//480

    lv_style_set_height(&style, LV_VER_RES);//272

    lv_style_set_x(&style,0);

    lv_style_set_x(&style,0);

   // lv_style_set_img_recolor_opa(&style, LV_OPA_COVER);

   // lv_style_set_img_recolor(&style, lv_color_black());

    lv_obj_t* img = lv_img_create(lv_scr_act());

    lv_obj_remove_style_all(img);

    lv_obj_add_style(img, &style, 0);

    sprintf(bgbuf,"S:pic/1.bin"); //1.bin stored in fat system of SPI flash

    lv_img_set_src(img,bgbuf);

    lv_obj_set_size(img,480,272);

    static lv_style_t bt_style;

    lv_style_init(&bt_style);

    lv_style_set_bg_color(&bt_style, lv_palette_main(LV_PALETTE_YELLOW));

    lv_style_set_bg_opa(&bt_style, LV_OPA_COVER);

    lv_obj_t* btn = lv_btn_create(img);

    lv_obj_set_pos(btn, 100, 30);

    lv_obj_set_size(btn, 150, 100);

   // lv_obj_center(img);

}
