导入闭包

将以下语句倒入目录下build.gradle文件内

 implementation 'com.github.WangcWj:WeSwipe:1.0.2'
 implementation 'cn.wang.we:network:1.0.0'

将以下语句倒入项目build.gradle文件内

创建RecyclerView子项布局文件

效果描述

整体效果图，因为使用RelativeLayout布局的缘故，将侧滑按钮给覆盖了

我们接下来选中侧滑按钮，由此我们可以看见按钮的位置

将侧滑按钮释放出来，看一下效果

创建RecyclerView适配器

描述

使用第三方API轮子时，不能像当初我们建立适配器一样继承一个RecyclerView.Adapter<VH>类，而要继承WeSwipeProxyAdapter<VH>抽象类
我们一般根据需求需要实现以下三个方法

 @Override
            public float getSwipeWidth() {
             //侧滑按钮的宽度
            }
            @Override
            public View needSwipeLayout() {
            //子项布局文件的最外层Layout
            }
            @Override
            public View onScreenView() {
             //子项布局文件的最外层Layout
            }

子项点击事件

//创建点击事件接口函数
public interface ParkingOnClick{
            void OnClickListener(View view,int Position);
        }

//点击事件调用
public void setOnclick(ParkingOnClick onclick) {
            this.onClick = onclick;
        }

//引入布局View中
return new ViewHolder(view,onClick);

//内部类实现点击事件
class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener

//构造函数
public ViewHolder(@NonNull View itemView,ParkingOnClick Listener)
this.Listener = Listener;

//点击事件外露
@Override
            public void onClick(View v) {
                if (Listener != null) {
                    Listener.OnClickListener(v, getPosition());
                }
            }

适配器代码

public class ParkingAdapter  extends WeSwipeProxyAdapter<ParkingAdapter.ViewHolder> {
        List<ParkingData> data = new ArrayList<>(  );
        private ParkingOnClick onClick;
        public ParkingAdapter(List<ParkingData> data ){
            this.data = data;
        }
        @NonNull
        @Override
        public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
            View view = LayoutInflater.from( parent.getContext() ).inflate( R.layout.parking_item,parent,false );
            return new ViewHolder(view,onClick);
        public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
            ParkingData bookingData = data.get(position);
            holder.BigPlace.setText(bookingData.getBigPlace());
            holder.SmallPlace.setText(bookingData.getSmallPlace());
            holder.ParkingNumber.setText(bookingData.getParkingNumber() + "");
            holder.Distance.setText(bookingData.getDistance());
             holder.SideText.setOnClickListener( new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Log.d( "Da",1+"" );
                    if (onClick != null){
                        onClick.OnClickListener( v,position );
                    }
                }
            } );
        public int getItemCount() {
            return data.size();
        class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener,WeSwipeHelper.SwipeLayoutTypeCallBack
        {
            private TextView BigPlace,SmallPlace,Distance,ParkingNumber,SideText;
            private LinearLayout SideLayout;
            private ParkingOnClick Listener;
            public ViewHolder(@NonNull View itemView,ParkingOnClick Listener) {
                super( itemView );
                this.Listener = Listener;
                BigPlace = itemView.findViewById( R.id.SimplePlace );
                SmallPlace = itemView.findViewById( R.id.detailPlace );
                Distance = itemView.findViewById( R.id.ParkingDistance );
                ParkingNumber = itemView.findViewById( R.id.ParkingNumber );
                SideText = itemView.findViewById( R.id.SideText );
                SideLayout = itemView.findViewById( R.id.SideLayout );
            }
            @Override
            public float getSwipeWidth() {
                return SideText.getWidth();
            public View needSwipeLayout() {
                return SideLayout;
            public View onScreenView() {
            public void onClick(View v) {
                if (Listener != null) {
                    Listener.OnClickListener(v, getPosition());
        //回调接口
        public interface ParkingOnClick{
            void OnClickListener(View view,int Position);
        //点击事件
        public void setOnclick(ParkingOnClick onclick) {
            this.onClick = onclick;
}

应用

解析xml数据

private void InitData(){
        String[] parkingArray = getResources().getStringArray(R.array.parking);
        for (int i = 0; i <parkingArray.length ; i+=4) {
            ParkingData data = new ParkingData(parkingArray[i],parkingArray[i+1],parkingArray[i+2],Integer.parseInt(parkingArray[i+3]));
            dataList.add(data);
        }
    }

绑定

WeSwipe.attach(ParkingRecycler);

private void InitRecycler(){
        LinearLayoutManager manager = new LinearLayoutManager(this);
        ParkingRecycler.setLayoutManager(manager);
        adapter = new ParkingAdapter(dataList);
        ParkingRecycler.setAdapter(adapter);
        WeSwipe.attach(ParkingRecycler);
    }

点击事件引用

adapter.setOnclick(new ParkingAdapter.ParkingOnClick() {
            @Override
            public void OnClickListener(View view, int Position) {
               //do anything...
            }
        });
