Usage

See sample project.

Header and footer RecyclerView

Basic sample

CompositeRecyclerAdapter compositeAdapter = new CompositeRecyclerAdapter();
  // header ViewItemAdapter header = new ViewItemAdapter(this) {

  @Override
  public int getAdapterId() {

return R.id.header;
  
}
 
}
; header.add(new ViewItem(this, R.layout.item_header_1));
 header.add(new ViewItem(this, R.layout.item_header_2));
  // footer ViewItemAdapter footer = new ViewItemAdapter(this) {
 ... 
}
; footer.add(new ViewItem(this, R.layout.item_footer_1));
  ItemAdapter itemAdapter = new ItemAdapter<String, SOMETHING_VIEW_HOLDER>(this) {

  // Override adapterId, onCreateViewHolder, onBindViewHolder 
}
 itemAdapter.add("hoge");
 itemAdapter.add("fuga");
 itemAdapter.add("piyo");
  // Add all adapters compositeAdapter.add(header);
 compositeAdapter.add(itemAdapter);
 compositeAdapter.add(footer);
  RecyclerView list = //ex (RecyclerView) findViewById(this, R.id.list);
  list.setLayoutManager(new LinearLayoutManager(this));
 list.setAdapter(compositeAdapter);
 // or list.setAdapter(itemAdapter);
 

get child items

LocalAdapterItem localItem = compositeAdapter.getLocalAdapterItem(100);
  localItem.getLocalAdapter();
 localItem.getLocalAdapterPosition();
  // ex) itemAdapter.get(localItem);
 

listeners

ItemAdapter itemAdapter = new ItemAdapter() {
 ... 
}
  // item click itemAdapter.setOnItemClickListener(new OnItemClickListener() {

  void onItemClicked(RecyclerView.ViewHolder holder, int position, String item) {
 ... 
}
 
}
);
  // item long click itemAdapter.setOnItemLongPressListener(new OnItemLongPressedListener() {

void onItemLongPressed(@NonNull RecyclerView.ViewHolder holder, int position, @NonNull T item) {
 ... 
}
 
}
);
 

Helpers

SpanSize Lookup support

GridLayoutManager gridLayoutManager = new GridLayoutManager(this, SPAN_SIZE);
  SpanSizeLookup spanSizeLookup =  new SpanSizeLookupBuilder(compositeAdapter)

.register(viewItem1, SPAN_SIZE)

.register(viewItemAdapter, SPAN_SIZE)

.register(itemAdapter2, SPAN_SIZE)

.build();
  gridLayoutManager.setSpanSizeLookup(spanSizeLookup);
  // You must use CompositeRecyclerAdapter!! recyclerView.setAdapter(compositeRecyclerAdapter);
 

Divider item decoration support

int dividerHeight = getResources().getDimensionPixelSize(R.dimen.divider_height);
  recyclerView.addItemDecoration(new DividerItemDecorationBuilder(compositeAdapter)

.dividerHeight(dividerHeight)

.dividerColor(Color.BLACK)

.register(itemAdapter1)

.register(AppendButtonViewItem.class)

.build());
 

Grid padding support

int padding = getResources().getDimensionPixelSize(R.dimen.padding);
  recyclerView.addItemDecoration(new GridPaddingItemDecorationBuilder(compositeAdapter, padding, SPAN_SIZE)

.paddingType(GridPaddingItemDecorationBuilder.PaddingType.BOTH)

.register(visibleChangeButton)

.register(itemAdapter2)

.register(AppendButtonViewItem.class)

.build());
 

Item drag support

ItemTouchHelper dragHelper = new DragItemTouchHelperBuilder(compositeAdapter)

.dragFlag(ItemTouchHelper.UP)

.dragFlag(ItemTouchHelper.DOWN)

.register(ItemAdapter3.class)

.build();

 dragHelper.attachToRecyclerView(recyclerView);
