RecycleView嵌套

效果视图

1.写协议Contract

public interface IShopContract {
public interface IShopView{
    public void LeftData(TypeBean type);
    public void RightData(ClothesBean clothesBean);
}
public interface IShowPresenter<IShopView>{
    public void attachView(IShopView iShopView);
    public void detachView(IShopView iShopView);
    public void getRseponseLeft();
    public void getRseponseRight();
}
public interface IShopModel{
    public void constantResponseData(MyCallBack callBack);
    public interface MyCallBack{
        public void ResponseLeftData(TypeBean type);
        public void ResponseRightData(ClothesBean clothesBean);
    }
}

2.V层

public class Fragment_fl extends Fragment implements IShopContract.IShopView {

@BindView(R.id.recycle_left)
RecyclerView recycleLeft;
@BindView(R.id.recycle_right)
RecyclerView recycleRight;
Unbinder unbinder;
private View view;
private IShopContract.IShowPresenter shopPresenter;

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    view = inflater.inflate(R.layout.fragment_fl, null);
    unbinder = ButterKnife.bind(this, view);
    shopPresenter = new ShopPresenter();
    shopPresenter.attachView(this);
    shopPresenter.getRseponseLeft();
    shopPresenter.getRseponseRight();
    return view;
}

@Override
public void onDestroyView() {
    super.onDestroyView();
    unbinder.unbind();
    shopPresenter.detachView(this);
}

@Override
public void LeftData(final TypeBean type) {
    getActivity().runOnUiThread(new Runnable() {

        private TypeAdapter typeAdapter;

        @Override
        public void run() {
            final List<TypeBean.DataBean> data = type.getData();
            typeAdapter = new TypeAdapter();
            typeAdapter.setData(data,getActivity());
            LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity());
            recycleLeft.setLayoutManager(linearLayoutManager);
            recycleLeft.setAdapter(typeAdapter);
            typeAdapter.setCallBack(new TypeAdapter.CallBack() {
                @Override
                public void setOnItemClick(View v, int position) {
                    data.remove(position);
                    typeAdapter.notifyDataSetChanged();
                }
            });
        }
    });
}

@Override
public void RightData(final ClothesBean clothesBean) {
    getActivity().runOnUiThread(new Runnable() {
        @Override
        public void run() {
            List<ClothesBean.DataBean> data = clothesBean.getData();
            ClothesAdapter adapter = new ClothesAdapter();
            adapter.setData(getActivity(),data);
            LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity());
            recycleRight.setLayoutManager(linearLayoutManager);
            recycleRight.setAdapter(adapter);
            adapter.notifyDataSetChanged();
        }
    });
}

3.P层

 public class ShopPresenter implements IShopContract.IShowPresenter<IShopContract.IShopView> {
IShopContract.IShopView shopView;
private IShopContract.IShopModel shopModel;
private SoftReference<IShopContract.IShopView> reference;

@Override
public void attachView(IShopContract.IShopView iShopView) {
    this.shopView=iShopView;
    shopModel = new ShopModel();
    reference = new SoftReference<>(shopView);
}

@Override
public void detachView(IShopContract.IShopView iShopView) {
    reference.clear();
}

@Override
public void getRseponseLeft() {
    shopModel.constantResponseData(new IShopContract.IShopModel.MyCallBack() {
        @Override
        public void ResponseLeftData(TypeBean type) {
            shopView.LeftData(type);
        }

        @Override
        public void ResponseRightData(ClothesBean clothesBean) {
            shopView.RightData(clothesBean);
        }
    });
}

@Override
public void getRseponseRight() {

}

4.M层

public class ShopModel implements IShopContract.IShopModel {

private void requestEnqueue(MyCallBack callBack) {
    requestEnqueue(callBack);
}

@Override
public void constantResponseData(final MyCallBack callBack) {
    OkGo.<String>get(Constant.lefturlString).execute(new StringCallback() {
        @Override
        public void onSuccess(Response<String> response) {
            String json = response.body().toString();
            Gson gson = new Gson();
            TypeBean typeBean = gson.fromJson(json, TypeBean.class);
            callBack.ResponseLeftData(typeBean);
        }
    });
    OkGo.<String>get(Constant.righturlString).execute(new StringCallback() {
        @Override
        public void onSuccess(Response<String> response) {
            String json = response.body().toString();
            Gson gson = new Gson();
            ClothesBean clothesBean = gson.fromJson(json, ClothesBean.class);
            callBack.ResponseRightData(clothesBean);
        }
    });
}

}

5.Adapter

public class TypeAdapter extends RecyclerView.Adapter<TypeAdapter.SubViewHolder> {
List<TypeBean.DataBean> data;
FragmentActivity activity;
private CallBack callBack;

@NonNull
public void setData(List<TypeBean.DataBean> data, FragmentActivity activity) {
    this.data = data;

}

    subViewHolder.textType.setText(data.get(position).getName());
    subViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            callBack.setOnItemClick(v,position);
        }
    });
}

        super(itemView);
        ButterKnife.bind(this,itemView);
    }
}
public interface CallBack{
    public void setOnItemClick(View v,int position);
}

public void setCallBack(CallBack callBack) {
    this.callBack = callBack;
}}

public class ClothesAdapter extends RecyclerView.Adapter<ClothesAdapter.SubViewHolder> {

    View inflate = View.inflate(activity, R.layout.right_item, null);
    SubViewHolder subViewHolder = new SubViewHolder(inflate);
    return subViewHolder;
}

@Override
public void onBindViewHolder(@NonNull SubViewHolder subViewHolder, int i) {
    subViewHolder.textBrand.setText(data.get(i).getName());
    RecycleItemAdapter recycleItemAdapter = new RecycleItemAdapter(activity, data);

    RecyclerView recycleClothes;
    public SubViewHolder(@NonNull View itemView) {
        super(itemView);
        ButterKnife.bind(this,itemView);
    }
}}

//嵌套里的recycleView

public class RecycleItemAdapter extends RecyclerView.Adapter<RecycleItemAdapter.SubViewHolder> {
FragmentActivity activity;
List<ClothesBean.DataBean> data;


public RecycleItemAdapter(FragmentActivity activity, List<ClothesBean.DataBean> data) {
    this.activity = activity;
    this.data = data;
}

@NonNull
@Override
public SubViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
    View inflate = View.inflate(activity, R.layout.recycle_item, null);
    SubViewHolder subViewHolder = new SubViewHolder(inflate);
    return subViewHolder;
}

@Override
public void onBindViewHolder(@NonNull SubViewHolder subViewHolder, int i) {
    List<ClothesBean.DataBean.ListBean> list = data.get(i).getList();
    subViewHolder.textClothes.setText(list.get(i).getName());
    Glide.with(activity).load(list.get(i).getIcon()).into(subViewHolder.imageClothes);
}

@Override
public int getItemCount() {
    return data.size();
}

public class SubViewHolder extends RecyclerView.ViewHolder {

    @BindView(R.id.image_clothes)
    ImageView imageClothes;
    @BindView(R.id.text_clothes)
