Android(安卓)自定义kotlin中BaseRecyclerViewAdapter

我们在开发中总是要用到自定义适配器的，那么总是在用到的时候，直接继承显然已经不能满足我们去装13的心情了，那么直接上码吧

下面是BaseRecyclerViewAdapter.kt的源码内容：

abstract class BaseRecyclerViewAdpater<T, VH: RecyclerView.ViewHolder>(var mContext: Context): RecyclerView.Adapter<VH>() {var mItemClickListener: OnItemClickListener<T>? = nullvar dataList: MutableList<T> = mutableListOf()fun setData(source: MutableList<T>) {        dataList = source        notifyDataSetChanged()    }    fun addData(source: MutableList<T>) {        dataList.addAll(source)        notifyDataSetChanged()    }override fun onBindViewHolder(holder: VH, position: Int) {holder.itemView.setOnClickListener {if (null != mItemClickListener) {mItemClickListener!!.onItemClick(dataList[position], position)}}}override fun getItemCount(): Int {        return dataList.size    }/** * Item点击事件 */interface OnItemClickListener<in T> {        fun onItemClick(item: T, position: Int)    }/** * 设置监听 */fun setOnItemClickListener(listener: OnItemClickListener<T>) {        this.mItemClickListener = listener    }}

具体的使用方法

UserListAdapter.kt

class UserListAdapter(var context: Context): BaseRecyclerViewAdpater<UserInfo, UserListAdapter.UserHolder>(context) {override fun onCreateViewHolder(parent: ViewGroup, position: Int): UserHolder {        val view = LayoutInflater.from(mContext).inflate(R.layout.item_user_info, parent, false)        return UserHolder(view)    }override fun onBindViewHolder(holder: UserHolder, position: Int) {        super.onBindViewHolder(holder, position)        val model = dataList[position]        holder.itemView.txtItemUserName.text = model.userName    }class UserHolder(view: View): RecyclerView.ViewHolder(view)}

业务逻辑代码

MainActivity.kt

class MainActivity: AppCompatActivity() {override fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)setContentView(R.layout.activity_main)var adapter = UserListAdapter(this)adapter.setOnItemClickListener(object : BaseRecyclerViewAdapter.OnItemClickListener<UserInfo> {            override fun onItemClick(item: UserInfo, position: Int) {                // what you want to do            }        })}}

以上就是所有的代码，希望对你有所帮助
