DataBinding RecyclerView的万能Adapter

RecyclerView万能的Adapter

如果使用了Data Binding Library框架,并使用了RecyclerView.可以使用这个Adapter
不用在为每一个不同的布局写单独的Adapter

功能

• 添加HeaderView和FooterView
• Item的Click事件处理
• 也可以添加额外的逻辑处理

源码地址 https://github.com/Doudada/DataBinding-Librar-RecyclerView-all-purpose-Adapter

使用

RecyclerView.setAdapter

item.xml

DataBindingRecyclerViewAdapter adapter = new DataBindingRecyclerViewAdapter
(mContext,R.layout.item,BR.yourVariable,variableList);
mRecyclerView.setAdapter(adapter);

setOnItemClick

adapter.setOnItemCkickListener(new DataBindingRecyclerViewAdapter.ItemClickListener(){
                        @Override
                        public void itemClick(View view, int position) {
                            //..................
                        }
                      });

addHeader And addFooter

mRecyclerView.setAdapter(adapter);
.....
LayoutInflater inflater = LayoutInflater.from(getContext());
View footerView = inflater.inflate(R.layout.recycler_view_load_more,binding.recyclerView,false);
adapter.addFooterView(footerView);
adapter.notifyDataSetChanged();

LayoutInflater inflater = LayoutInflater.from(getContext());
View footerView = inflater.inflate(R.layout.recycler_view_load_more,binding.recyclerView,false);
adapter.addFooterView(footerView);
mRecyclerView.setAdapter(adapter);

额外的逻辑处理

如果只给item添加一个variable还不够的话可以另外添加

adapter.setOnBindingViewHolderListener(new DataBindingRecyclerViewAdapter.OnBindingViewHolderListener() {
                            @Override
                            public void onHolderBinding(DataBindingRecyclerViewAdapter.DataBindingViewHolder holder, int position) {
                                ViewDataBinding binding = DataBindingUtil.getBinding(holder.itemView);
                                binding.setVariable(BR.presenter,new MyPresenter());

                            }
                        });

item.xml
