Content
ViewHolder
public class DataGetter<T> {
final public T previous;
final public T next;
final public T data;
public DataGetter(T previous, T data, T next) {
this.previous = previous;
this.next = next;
this.data = data;
}
}
public interface IViewHolder<T> {
// create view and bind to this view holder
void bind(View view);
// position: item position in list
// getter: access current item and previous and next, this is useful when decide show or hide some view depened on previous item or next item or all
void onDataChange(DataGetter<T> getter, int position);
}
ViewCreator
public interface IViewCreator<T> {
// call in getView
View view(ViewGroup container);
// call in getItemViewType
int viewTypeFor(T data, int position, int itemCount);
// call in getViewTypeCount
int viewTypeCount();
}
Single Layout
// ViewCreator just a implement of IViewCreator, accept layout id and view holder factory
new AutoListAdapter(items, new ViewCreator(R.layout.list_item, () -> new ViewHolder());
Multiple Layout
// ViewCreatorCollection just another implement of IViewCreator, it create different view depends on values of item and position and itemCount.
// It useful when getViewTypeCount > 1
ViewCreatorCollection<DataType> collection = new ViewCreatorCollection.Builder<DataType>()
.addFilter((data, position, itemCount) -> position == 1, R.layout.list_item_1, ViewHolder1::new)
.addFilter((data, position, itemCount) -> position == 2, R.layout.list_item_2, ViewHolder2::new).build();
new AutoListAdapter(items, collection);
Paging ListView
ViewCreatorCollection collection = new ViewCreatorCollection.Builder<DataType>()
.loadingResId(R.layout.list_item_loading)
.addFilter((data, position, itemCount) -> data != null, R.layout.list_item, ViewHolder::new)
.build();
// pagingListener will be called when arrive the last position in ListView
new AutoListPagingAdapter<DataType>(stocks, collection, pagingListener);
