RecyclerViewHeader

已棄用

當我認為 RecyclerView 是全新且困難的時候，我創建了這個函式庫。編寫一個可以擴展多種類型視圖的適配器似乎是一項艱鉅的工作。實際上， RecyclerViewHeader只是一個簡單問題的複雜解決方案。無需使用此庫，只需學習如何建立多類型RecyclerView.Adapter即可。從長遠來看，它會為你帶來很多價值，而且一點也不難。檢查Migration部分以取得此類Adapter.

不會有新的發展。

感謝大家的支持！

如果您仍然想使用這個庫，請查看舊的 README.md。

只需使用可以膨脹多種類型項目的RecyclerView.Adapter即可。

這是您可以使用的最簡單的一種：

 class ExampleAdapter : RecyclerView . Adapter < RecyclerView . ViewHolder >() {

    companion object {
        private const val VIEW_TYPE_HEADER = 4815
        private const val VIEW_TYPE_ITEM = 1623
    }

    private val itemDataSetSize : Int get() = TODO ( " provide the size of your `ITEM` dataset " )

    override fun onCreateViewHolder ( parent : ViewGroup , viewType : Int ): RecyclerView . ViewHolder {
        when (viewType) {
            VIEW_TYPE_HEADER -> TODO ( " create your HEADER ViewHolder " )
            VIEW_TYPE_ITEM -> TODO ( " create your ITEM ViewHolder " )
            else -> error( " Unhandled viewType= $viewType " )
        }
    }

    override fun onBindViewHolder ( holder : RecyclerView . ViewHolder , position : Int ) {
        when ( val viewType = getItemViewType(position)) {
            VIEW_TYPE_HEADER -> TODO ( " bind your HEADER ViewHolder " )
            VIEW_TYPE_ITEM -> TODO ( " bind your ITEM ViewHolder " )
            else -> error( " Unhandled viewType= $viewType " )
        }
    }

    override fun getItemCount (): Int = itemDataSetSize + 1 // 1 for header

    override fun getItemViewType ( position : Int ) = when (position) {
        0 -> VIEW_TYPE_HEADER
        else -> VIEW_TYPE_ITEM
    }
}
