A quick adapter library for RecyclerView, GridView, ListView, ViewPager, Spinner. It abstracts the boilerplate of item view types, item layouts, viewholders, span sizes , and more, in order to simplify building complex screens with multiple view types.
If you are using version 2.x please check here
- Support ViewBinding、DataBinding、DefaultBinding.
- Multiple view types without any ViewHolder
- Simple, flexible
implementation 'com.github.thepacific:adapter:{lastVersion}'class MyType1(val data: Any) : SimpleRecyclerItem()
class MyType2(val data: Any) : SimpleRecyclerItem()
class MyType3(val data: Any) : SimpleRecyclerItem()
val adapter = RecyclerAdapter()
adapter.onClickListener = View.OnClickListener { }
adapter.imageLoader = adapter.imageLoader = object : AdapterImageLoader {}
val item1 = MyType1(Any())
val list2 = mutableListOf<MyType2>()
val list3 = mutableListOf<MyType3>()
adapter.add(item1)
adapter.addAll(list2.toList())
adapter.addAll(list3.toList())Extend SimpleRecylcerItem. Optionally, you may implement RecyclerItem
class MovieItem(val data: Movie) : SimpleRecyclerItem() {
override fun getLayout(): Int {
return R.layout.item_movie
}
override fun bind(holder: AdapterViewHolder) {
val binding = holder.binding(ItemMovieBinding::bind)
binding.itemPosterTitle.text = data.name
binding.itemPosterRunningTime.text = data.showTime
// attach UI listeners
holder.attachOnClickListener(R.id.item_poster_post)
holder.attachOnLongClickListener(R.id.item_poster_post)
holder.attachOnCheckedChangeListener(R.id.item_poster_post)
holder.attachOnTouchListener(R.id.item_poster_post)
holder.attachImageLoader(R.id.item_poster_post)
holder.attachTextChangedListener(R.id.item_poster_post)
holder.detachTextChangedListener(R.id.item_poster_post)
}
override fun bindPayloads(holder: AdapterViewHolder, payloads: List<Any>?) {
}
override fun unbind(holder: AdapterViewHolder) {
}
// You may override other methods
}Set OnClickListener、OnLongClickListener、OnTouchListener、OnCheckedChangeListener、ImageLoader and TextWatcher
class HomeFragment : Fragment() {
private val adapter = RecyclerAdapter()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
// adapter.setOnTouchListener(OnTouchListener listener);
// adapter.setOnLongClickListener(OnLongClickListener listener);
// adapter.setOnCheckedChangeListener(OnCheckedChangeListener listener);
adapter.onClickListener = View.OnClickListener { v ->
// AdapterUtils
val holder: AdapterViewHolder = AdapterUtils.getHolder(v)// get ViewHolder
val textView = holder.itemView.findViewById<TextView>(R.id.item_poster_title)// find view
val item: MovieItem = holder.item()// get Item
val itemCount: Int = holder.itemCount// get adapter data size
val position = holder.bindingAdapterPosition // get item position
}
// load image
adapter.imageLoader = object : AdapterImageLoader {
override fun onImageLoad(imageView: ImageView, holder: AdapterViewHolder) {
GlideApp.with(this@HomeFragment)
.load(holder.item<MovieItem>().data.img)
.into(imageView)
}
}
// TextWatcher
adapter.textChangedListener = object : AdapterTextWatcher {
override fun beforeTextChanged(
v: TextView,
s: CharSequence?,
start: Int,
count: Int,
after: Int,
holder: AdapterViewHolder
) {
// AdapterUtils
}
override fun onTextChanged(
v: TextView,
s: CharSequence?,
start: Int,
before: Int,
count: Int,
holder: AdapterViewHolder
) {
// AdapterUtils
}
override fun afterTextChanged(v: TextView, s: Editable, holder: AdapterViewHolder) {
// AdapterUtils
}
}
}
}data set changed callback , it's useful to show or hide empty view
adapter.setOnDataSetChanged(OnDataSetChanged onDataSetChanged);
