#购物车圈子，adapter

这篇博客探讨了购物车圈子的实现，重点关注了一个名为Fragment2的Fragment类，它实现了ConteatInterface.Fragment2Interface接口，并包含了QuanAdpater的使用。在Fragment中，初始化了一个包含QuanBean.ResultBean对象的列表，以及一个页面计数器。同时，博客还介绍了QuanAdpater，这是RecyclerView的适配器，用于展示QuanBean.ResultBean数据。

public class Fragment2 extends Fragment implements ConteatInterface.Fragment2Interface {
List<QuanBean.ResultBean> list= new ArrayList<>();
ConteatInterface.PresenterInterface presenterInterface;
QuanAdpater adpater;
int page = 1;
@BindView(R.id.xrecyc_view)
XRecyclerView xrecycView;
Unbinder unbinder;

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.layout_fragment2, container, false);
    unbinder = ButterKnife.bind(this, view);
    return view;
}

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
    layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
    xrecycView.setLayoutManager(layoutManager);
    adpater = new QuanAdpater(list, getActivity());
    xrecycView.setAdapter(adpater);

    presenterInterface = new MyPresenter<>(this);
    presenterInterface.getQuanzi(page + "");

    xrecycView.setLoadingMoreEnabled(true);
    xrecycView.setPullRefreshEnabled(true);
    xrecycView.setLoadingListener(new XRecyclerView.LoadingListener() {
        @Override
        public void onRefresh() {
            presenterInterface.getQuanzi(page + "");
        }

        @Override
        public void onLoadMore() {
            page++;
            presenterInterface.getQuanzi(page + "");
        }
    });
}

@Override
public void showQuanzi(Object o) {
    list.clear();
    xrecycView.loadMoreComplete();
    xrecycView.refreshComplete();
    QuanBean quanBean = (QuanBean) o;
    list.addAll(quanBean.getResult());
    adpater.notifyDataSetChanged();
}

@Override
public void onDestroyView() {
    super.onDestroyView();
    unbinder.unbind();
    if (presenterInterface!=null){
        presenterInterface.getDatas();
    }

}

}
