1、建立entity類
class InternentBarEntity {
var bname: String? = null
var barea: String? = null
var badddata: String? = null
var bimage: String? = null
var bid: String? = null
}
2、建立adapter類
class InternetBarAdapter( private val entityList: List) : RecyclerView.Adapter() {
private var mOnItemClickListener: OnItemClickListener? = null
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
val view = LayoutInflater.from(parent.context).inflate(R.layout.tab_item, null)
return ViewHolder(view)
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
val entity = entityList[position]
try {
holder.item_intnbname.text = entity.bname
} catch (e: Exception) {
e.printStackTrace()
}
//判斷是否設定了監聽器
if (mOnItemClickListener != null) {
//為ItemView設定監聽器-
holder.itemView.setOnClickListener {
val position = holder.layoutPosition // 1
mOnItemClickListener!!.onItemClick(holder.itemView, position) // 2
}
}
}
override fun getItemCount(): Int {
return entityList.size
}
inner class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
var item_intnbname = itemView.findViewById(R.id.tab_tv) as TextView
}
// 删除 打勾 全選
fun cleckAll(is_checked: Int) { //全選 删除多少那裡要删除全部
for (a in entityList.indices) {
if (is_checked == a) {
entityList.get(a).bname = "選中了"
} else {
}
}
notifyDataSetChanged()
}
interface OnItemClickListener {
fun onItemClick(view: View, position: Int)
}
fun setOnItemClickListener(onItemClickListener: OnItemClickListener) {
this.mOnItemClickListener = onItemClickListener
}
}
3、添加recyclerview依賴
compile('com.android.support:recyclerview-v7:25.1.1') {
force = true
}
4、加載資料實作kotlin 代碼
private val barEntityList = ArrayList()
private var barAdapter: InternetBarAdapter? = null
private var lastposion: Int = 0
private var pagenum = 1
private var pageContent:Int = 0
private var pageSize = 10
public fun initrecycleView(){
var internentBarEntity2:InternentBarEntity= InternentBarEntity()
internentBarEntity2.badddata = "位址122"
internentBarEntity2.bname="名稱111222"
barEntityList.add(internentBarEntity2)
for (a in 0..19) {
var internentBarEntity:InternentBarEntity=InternentBarEntity()
internentBarEntity.badddata = "位址1"
internentBarEntity.bname="名稱111=="+a
barEntityList.add(internentBarEntity)
// if (a==6){
// break
// }
}
barAdapter = InternetBarAdapter( barEntityList)
barAdapter!!.setOnItemClickListener(object : InternetBarAdapter.OnItemClickListener {
override fun onItemClick(view: View, position: Int) {
barAdapter!!.cleckAll(position)
LgqLogutil.e("ITEM"+position)
}
})
mRecyclerView.layoutManager = LinearLayoutManager(context)
mRecyclerView.adapter = barAdapter
mRecyclerView.isNestedScrollingEnabled = false//禁止滑動
mRecyclerView.isFocusable = false//導航欄切換不再focuse
mRecyclerView.addOnScrollListener(object : RecyclerView.OnScrollListener() {
//用來标記是否正在向最後一個滑動，既是否向右滑動或向下滑動
internal var isSlidingToLast = false
override fun onScrollStateChanged(recyclerView: RecyclerView?, newState: Int) {
val manager = recyclerView!!.layoutManager as LinearLayoutManager
// 當不滾動時
if (newState == RecyclerView.SCROLL_STATE_IDLE) {
//擷取最後一個完全顯示的ItemPosition
lastposion = manager.findLastCompletelyVisibleItemPosition()
// Log.i("lgq","..........dddddd====="+"....."+lastposion);
val totalItemCount = manager.itemCount
if (lastposion == totalItemCount - 1 && isSlidingToLast) {
pagenum++
if (pagenum > pageContent) {
Toast.makeText(activity,"yidaodi",Toast.LENGTH_LONG).show()
return
}
}
}
}
override fun onScrolled(recyclerView: RecyclerView?, dx: Int, dy: Int) {
super.onScrolled(recyclerView, dx, dy)
//dx用來判斷橫向滑動方向，dy用來判斷縱向滑動方向
//大于0表示，正在向右滾動；小于等于0 表示停止或向左滾動
isSlidingToLast = dy > 0
}
})
}
