BaseRecyclerViewAdapter封裝
<p><code>abstract class BaseRecyclerViewAdapter<D, VH : BaseRecyclerViewAdapter.BaseViewHolder>(layoutResId: Int, data: MutableList<D>) : RecyclerView.Adapter<VH>() {

open var layoutResId: Int = 0 //item資源Id
open var data: List<D> = data //數據集合
open var view: View? = null

init {
    if (layoutResId != 0)
        this.layoutResId = layoutResId
    else
        throw NullPointerException("請設置Item資源Id")
}

override fun onBindViewHolder(holder: VH, position: Int) {
    bindData(holder, data[position],position)
}

override fun getItemCount(): Int {
    return data.size
}

/**
 * 綁定數據
 * @param  holder
 * *
 * @param data
 */
protected abstract fun bindData(holder: VH, data: D,position: Int)

open class BaseViewHolder : RecyclerView.ViewHolder{
    open var mView: View? = null
    constructor(view: View): super(view){
        mView = view
    }
}

}
</code></p>
<p>在Activity中定義MyRecyclerViewAdapter</p>
<p><code>
inner class MyRecyclerViewAdapter<VH: MyViewHolder>(layoutResId: Int, data: MutableList<GirlBean>) : BaseRecyclerViewAdapter<GirlBean, VH>(layoutResId, data) {

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): VH {
        view = LayoutInflater.from(parent.context).inflate(layoutResId, parent, false)
        return MyViewHolder(view!!) as VH
    }

    override fun bindData(holder: VH, data: GirlBean,position: Int) {
        this@MainActivity.loadImg(data.url,holder.imageview!!)
        holder.textview?.text = data.who
        loadImg(data.url, holder.imageview!!)
        holder.imageview?.setOnClickListener { mListener.onItemClick(position, holder.imageview!!) }
    }
}

inner class MyViewHolder(view: View) : BaseRecyclerViewAdapter.BaseViewHolder(view) {
    var imageview: ImageView? = null
    var textview: TextView? = null
    init {
        imageview = mView?.findViewById(R.id.imageview) as ImageView?
        textview = mView?.findViewById(R.id.textview) as TextView?
    }
}</code></p>

<p>初始化時使用</p>
<p><code>
mAdapter = MyRecyclerViewAdapter(R.layout.item_girl,mList)
recyclerview.adapter = mAdapter

</code></p>
