SectionedRecyclerViewAdapter
An Adapter that allows a RecyclerView to be split into Sections with headers and/or footers.
In addition, each Section can have its state(Loading/Loaded/Failed/Empty) controlled individually.
Gradle Dependency
Add this to the dependencies section in your project-level build.gradle file:
compile 'io.github.luizgrp.sectionedrecyclerviewadapter:sectionedrecyclerviewadapter:1.1.3'Basic usage
1) Create a custom Section class extending StatelessSection
class MySection extends StatelessSection {
List<String> itemList = Arrays.asList("Item1", "Item2", "Item3");
public MySection() {
// call constructor with layout resources for this Section header and items
super(new SectionParameters.Builder(R.layout.section_item)
.headerResourceId(R.layout.section_header)
.build());
}
@Override
public int getContentItemsTotal() {
return itemList.size();
// number of items of this section
}
@Override
public RecyclerView.ViewHolder getItemViewHolder(View view) {
// return a custom instance of ViewHolder for the items of this section
return new MyItemViewHolder(view);
}
@Override
public void onBindItemViewHolder(RecyclerView.ViewHolder holder, int position) {
MyItemViewHolder itemHolder = (MyItemViewHolder) holder;
// bind your view here
itemHolder.tvItem.setText(itemList.get(position));
}
}
2) Create a custom ViewHolder for the section items:
class MyItemViewHolder extends RecyclerView.ViewHolder {
private final TextView tvItem;
public MyItemViewHolder(View itemView) {
super(itemView);
tvItem = (TextView) itemView.findViewById(R.id.tvItem);
}
}
3) Set up your ReclyclerView with the SectionedRecyclerViewAdapter
// Create an instance of SectionedRecyclerViewAdapter SectionedRecyclerViewAdapter sectionAdapter = new SectionedRecyclerViewAdapter();
// Add your Sections sectionAdapter.addSection(new MySection());
// Set up your RecyclerView with the SectionedRecyclerViewAdapter RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
recyclerView.setAdapter(sectionAdapter);
