class MyAdapter : AdapterRecyclerView<String?>(R.layout.my_item, R.layout.progress_view, R.layout.item_error,R.id.btnTrayAgain) {
override fun onBindView(viewHolder: ItemViewHolder, position: Int, context: Context, element: String?) {
val itemView = viewHolder.itemView
itemView.txt_title.setText("$element $position")
}
}
val myAdapter = MyAdapter()
// onClick Error Button
myAdapter.onRetryClicked = {
myAdapter.loadingState()
// fake request or load other items...
recyclerView.postDelayed({
myAdapter.loadedState(tempItems)
}, 2000)
}
// set Data in List
myAdapter.loadedState(tempItems)
recyclerView.layoutManager = GridLayoutManager(this@MainActivity, 2)
recyclerView.adapter = myAdapter
// set onLoad More Listener for Pagination
recyclerView.onLoadMoreListener {
if (myAdapter.mustLoad) {
myAdapter.loadingState()
// failed state
recyclerView.postDelayed({
myAdapter.failedState()
}, 2000)
}
}
// Set onClick Item Listener
recyclerView.onItemClickListener({ position ->
if (position == myAdapter.itemCount - 1 && !myAdapter.mustLoad) {
return@onItemClickListener
}
Toast.makeText(applicationContext, "item click : ${myAdapter.getItem(position)}$position", Toast.LENGTH_SHORT).show()
}, { position ->
if (position == myAdapter.itemCount - 1 && !myAdapter.mustLoad) {
return@onItemClickListener
