想要为 Android 电视创建自定义视图

Question

I have already gone through several different available Questions related to this, but not found very much useful.

1. Android TV. Adding custom views to VerticalGridFragment

How I can customize the View Inside the RowSupportFragment or Like is there any other way to achieve the same.

Answer 1

Are you using Presenter right? I think you need to use different types same way RecyclerView and Adapters has the itemViewType and transform your BaseCardView based on some rule, it could be the position or the type of it. I manage to do something like this for a row with the "View All" last card:

// This is just a simple FrameLayout with an ImageView or a TextView...

var firstItem: Any? = null

class PortraitTitleCardPresenter(context: Context) :
    AbstractCardPresenter<BaseCardView>(context) {


    override fun onCreateView(): BaseCardView {
        val cardView = BaseCardView(context, null, R.style.BaseCard)
        cardView.isFocusable = true
        cardView.addView(LayoutInflater.from(context).inflate(R.layout.item_home, null))

        return cardView
    }

    override fun onBindViewHolder(card: Any, cardView: BaseCardView) {
        if(firstItem == null) {
            firstItem = card
            //Do something with firstItem...
        }

        if (card is ItemTitleType) {
            cardView.image.visibility = View.VISIBLE
            cardView.viewAll.visibility = View.GONE
            
            Glide.with(context)
                .load(card.imageUrl)
                .centerCrop()
                .apply(RequestOptions().placeholder(R.drawable.ic_wm_black)
                    .diskCacheStrategy(DiskCacheStrategy.RESOURCE)
                ).into(cardView.image)
        }

        if (card is ViewAllType) {
            cardView.image.visibility = View.GONE
            cardView.viewAll.visibility = View.VISIBLE
        }
    }
}
