How to customise Header Item of Row in android leanback library?

Question

I am new in Android TV development.

I use android leanback library for this. Also I I use BrowseSupportFragment and RowsSupportFragmen.

Here I want to customise the HeaderItem shown in the picture.

Specially I want to change its font. I check lots of things but not getting proper solution for this.

Thank You.

Answer 1

If you use BrowseSupportFragment you can use method setHeaderPresenterSelector() and register own presenter for headers. It should inherard from RowHeaderPresenter

If you want to override all header at once then you can create file res/values/layout/lb_row_header.xml and redefine layout for default header presenter.

I think setHeaderPresenterSelector is for left side drawer header not for this one which i mention in the question. – Cicisbeo

Here I am Using RowsSupportFragment – Cicisbeo

Yes setHeaderPresenterSelector is for left side drawer. – Cornflakes

@Cicisbeo i've you got any solution for this, I'm also looking for that solution – Cornflakes

@Cornflakes I did lots of r&d about that but not got any solution. Also one thing I see in TV app development, in all cases of TV development apps there is no customisation. Leanback library give lots of functionalities as it is default and less customisation is available in that – Cicisbeo

Answer 2

Try this:

 override fun onBindRowViewHolder(holder: RowPresenter.ViewHolder?, item: Any?) {
    super.onBindRowViewHolder(holder, item)
    val textView = holder?.headerViewHolder?.view?.findViewById<RowHeaderView>(R.id.row_header)
    textView?.run {
        setTextColor(Color.WHITE)
        setTextSize(TypedValue.COMPLEX_UNIT_SP, 12.5f)
        isAllCaps = true
        setFontFamily(context, R.font.hind_bold)
    }
 }

If you enabled non-transitive R classes, use androidx.leanback.R.id.row_header – Zymometer
