android TV select item of BrowseSupportFragment/RowsSupportFragment programmatically by index

Question

I want to set selected view by index inside the row I'm in. Logically it might be something like this:

getRowsSupportFragment().getRowViewHolder(rowIndex).setSelectedPosition(viewIndex);

Well there is not anything like setSelectedPosition in the list of function of getRowViewHolder(0)
I have managed to change selected row by index with this line : getRowsSupportFragment().setSelectedPosition(index); But I want to change selected View inside the row..

Thanks in Advance!

To select a specific item in a row you simply call setSelectedPosition().

In Java:

setSelectedPosition(rowindex, true, new ListRowPresenter.SelectItemViewHolderTask(channelIndex));

In Kotlin:

setSelectedPosition(rowindex, true, SelectItemViewHolderTask(channelIndex))

Kotlin equivalent

setSelectedPosition(rowIndex, true, object : ListRowPresenter.SelectItemViewHolderTask(itemIndex){
            override fun run(holder: Presenter.ViewHolder?) {
                val itemView = holder?.view
                //do whatever you want
            }
        })

    val rowViewHolder = getRowViewHolder(rowIndex)
    val horizontalGridView = (rowViewHolder as ListRowPresenter.ViewHolder).gridView
    horizontalGridView.setSelectedPosition(cardPos)

Above can be used to select required card in required row and if still focus is not handled adding below code helps.

   horizontalGridView.getChildAt(cardPos).requestFocus()
