Do you mean that your button and search box are always fixed at the top? , if so, there is no need to use header. It is better to lay it out separately.
It would be nice if the part below your navigation bar is a whole and can be scrolled beyond the screen. That is, your carousel box and the cv below are a whole. Pack the above button, search box, and carousel box into a view and set it as the header of cv.
