Easy way to build RecyclerView.Adapter.
This adapter also has multiple ItemViewType, if needed.
- add JitPack repository to your project root
build.gradle.
repositories {
maven { url "https://jitpack.io" }
}- add the dependency
dependencies {
compile 'com.github.chuross.recyclerview-adapters:recyclerview-adapters:1.x.x'
}if you use RxJava2, you can use Rx support extension!
This extension provide databinding via Flowable.
dependencies {
compile 'com.github.chuross.recyclerview-adapters:recyclerview-adapters:1.x.x'
compile 'com.github.chuross.recyclerview-adapters:recyclerview-adapters-rx:1.x.x'
}if you use Android DataBinding, you can use binding support extension!
This extension provide databinding via ObservableList.
dependencies {
compile 'com.github.chuross.recyclerview-adapters:recyclerview-adapters:1.x.x'
compile 'com.github.chuross.recyclerview-adapters:recyclerview-adapters-databinding:1.x.x'
}See sample project.
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);
/**
* also can set ItemAdapter only.
* ex) list.setAdapter(itemAdapter);
*/LocalAdapterItem localItem = compositeAdapter.getLocalAdapterItem(100);
localItem.getLocalAdapter();
localItem.getLocalAdapterPosition();
// ex)
itemAdapter.get(localItem.getLocalAdapterPosition());CompositeRecyclerAdapter is nestable.
CompositeRecyclerAdapter compositeAdapter = new CompositeRecyclerAdapter();
// create nested adapter
CompositeRecyclerAdapter nestedAdapter = new CompositeRecyclerAdapter();
nestedAdapter.add(new ViewItem(context));
nestedAdapter.add(new ViewItem(context));
// add nested adapter
compositeAdapter.add(nestedAdapter);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) { ... }
});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);int dividerHeight = getResources().getDimensionPixelSize(R.dimen.divider_height);
recyclerView.addItemDecoration(new DividerItemDecorationBuilder(compositeAdapter)
.dividerHeight(dividerHeight)
.dividerColor(Color.BLACK)
.register(itemAdapter1)
.register(AppendButtonViewItem.class)
.build());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());ItemTouchHelper dragHelper = new DragItemTouchHelperBuilder(compositeAdapter)
.dragFlag(ItemTouchHelper.UP)
.dragFlag(ItemTouchHelper.DOWN)
.register(ItemAdapter3.class)
.build();
dragHelper.attachToRecyclerView(recyclerView);Copyright 2017 chuross
