Usage

Step 1. Create a class, It would be yourdata model/Java bean, for example:

publicclassTextItem {publicfinal@NonNullStringtext;publicTextItem(@NonNullStringtext) {this.text =text;    }}

Step 2. Create a class extendsItemViewBinder<T, VH extends ViewHolder>, for example:

publicclassTextItemViewBinderextendsItemViewBinder<TextItem,TextItemViewBinder.TextHolder> {staticclassTextHolderextendsRecyclerView.ViewHolder {private@NonNullfinalTextViewtext;TextHolder(@NonNullViewitemView) {super(itemView);this.text = (TextView)itemView.findViewById(R.id.text);        }    }@NonNull@OverrideprotectedTextHolderonCreateViewHolder(@NonNullLayoutInflaterinflater,@NonNullViewGroupparent) {Viewroot =inflater.inflate(R.layout.item_text,parent,false);returnnewTextHolder(root);    }@OverrideprotectedvoidonBindViewHolder(@NonNullTextHolderholder,@NonNullTextItemtextItem) {holder.text.setText("hello: " +textItem.text);Log.d("demo","position: " +getPosition(holder));Log.d("demo","adapter: " +getAdapter());    }}

Step 3. Justregister your types and setup yourRecyclerView andList<Object> in yourActivity, for example:

publicclassSampleActivityextendsAppCompatActivity {privateMultiTypeAdapteradapter;privateItemsitems;@OverrideprotectedvoidonCreate(BundlesavedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);RecyclerViewrecyclerView = (RecyclerView)findViewById(R.id.list);adapter =newMultiTypeAdapter();adapter.register(TextItem.class,newTextItemViewBinder());adapter.register(ImageItem.class,newImageItemViewBinder());adapter.register(RichItem.class,newRichItemViewBinder());recyclerView.setAdapter(adapter);TextItemtextItem =newTextItem("world");ImageItemimageItem =newImageItem(R.mipmap.ic_launcher);RichItemrichItem =newRichItem("小艾大人赛高",R.mipmap.avatar);items =newItems();for (inti =0;i <20;i++) {items.add(textItem);items.add(imageItem);items.add(richItem);        }adapter.setItems(items);adapter.notifyDataSetChanged();    }}

Advanced usage

adapter.register(Data.class).to(newDataType1ViewBinder(),newDataType2ViewBinder()).withLinker((position,data) ->data.type ==Data.TYPE_2 ?1 :0);

adapter.register(Data.class).to(newDataType1ViewBinder(),newDataType2ViewBinder()).withClassLinker((position,data) -> {if (data.type ==Data.TYPE_2) {returnDataType2ViewBinder.class;    }else {returnDataType1ViewBinder.class;    }});
