使用方式

1. 使用方法
CanRefresh是一个刷新控件，可适配任何view，可下拉刷新上拉加载。OnRefreshListener是下拉监听，OnLoadMoreListener是上拉监听。refresh.setStyle(type, type)中第一个参数是下拉的风格，第二个参数是上拉的风格。风格有四种，经典风格、在视图前面、在视图后面、居于拉动间隔的中间。预置五种刷新效果，经典效果、旋转效果、google效果、StoreHouse效果、Yalantis效果。可自由组合。若不想要预置的效果，只需要将CanRefresh类和CanRefreshLayout类拷入自己项目中，继承CanRefresh类自己写效果即可。

public class RVRefreshFragment extends Fragment implements CanRefreshLayout.OnRefreshListener, CanRefreshLayout.OnLoadMoreListener {


    public final static String TYPE = "type";

    @Bind(R.id.can_content_view)
    RecyclerView recyclerView;
    @Bind(R.id.refresh)
    CanRefreshLayout refresh;
    CanRVAdapter adapter;

    int type;
    LinearLayoutManager mLayoutManager;

    public static RVRefreshFragment newInstance(int type) {
        RVRefreshFragment fragment = new RVRefreshFragment();
        Bundle bundle = new Bundle();
        bundle.putInt(TYPE, type);
        fragment.setArguments(bundle);
        return fragment;
    }

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        type = getArguments().getInt(TYPE, 0);

    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        int layoutId;
        switch (type) {
            case 0:
                layoutId = R.layout.fragment_rv_classic;
                mLayoutManager = new LinearLayoutManager(getContext(), LinearLayoutManager.VERTICAL, false);
                break;

            case 1:
                layoutId = R.layout.fragment_rv_google;
                mLayoutManager = new GridLayoutManager(getContext(), 2);
                break;
            case 2:
                layoutId = R.layout.fragment_rv_yalantis;
                mLayoutManager = new LinearLayoutManager(getContext(), LinearLayoutManager.VERTICAL, false);
                break;

            case 3:
                layoutId = R.layout.fragment_rv_store;
                mLayoutManager = new GridLayoutManager(getContext(), 3);
                break;

            default:
                layoutId = R.layout.fragment_rv_classic;
                mLayoutManager = new LinearLayoutManager(getContext(), LinearLayoutManager.VERTICAL, false);
                break;
        }


        View v = inflater.inflate(layoutId, container, false);
        ButterKnife.bind(this, v);


        if (type==3){

            StoreHouseRefreshView storeHouseRefreshView = (StoreHouseRefreshView) v.findViewById(R.id.can_refresh_header);

            storeHouseRefreshView.initWithString("Hello World");
        }

        initView();
        return v;


    }


    private void initView() {

        refresh.setOnLoadMoreListener(this);
        refresh.setOnRefreshListener(this);


        refresh.setStyle(type, type);


        recyclerView.setLayoutManager(mLayoutManager);

        adapter = new CanRVAdapter<MainBean>(recyclerView, R.layout.item_main) {


            @Override
            protected void setView(CanHolderHelper helper, int position, MainBean model) {
                helper.setText(R.id.tv_title, model.title);
                helper.setText(R.id.tv_content, model.content);

            }

            @Override
            protected void setItemListener(CanHolderHelper helper) {

                helper.setItemChildClickListener(R.id.tv_title);
                helper.setItemChildClickListener(R.id.tv_content);

            }
        };

        recyclerView.setAdapter(adapter);


        adapter.setOnItemListener(new CanOnItemListener() {

            public void onItemChildClick(View view, int position) {

                MainBean bean = (MainBean) adapter.getItem(position);
                switch (view.getId()) {


                    case R.id.tv_title:

                        App.getInstance().show(bean.title);
                        break;

                    case R.id.tv_content:
                        App.getInstance().show(bean.content);
                        break;
                }


            }

        });


        adapter.setList(MainBean.getList());


    }


    @Override
    public void onDestroyView() {
        super.onDestroyView();
        ButterKnife.unbind(this);
    }

    @Override
    public void onRefresh() {

        refresh.postDelayed(new Runnable() {
            @Override
            public void run() {
                adapter.setList(MainBean.getList());
                refresh.refreshComplete();
            }
        }, 1000);

    }

    @Override
    public void onLoadMore() {

        refresh.postDelayed(new Runnable() {
            @Override
            public void run() {

                adapter.addMoreList(MainBean.getList());
                refresh.loadMoreComplete();
            }
        }, 1000);

    }
}

2. 注意事项
虽说能适配任何view，但用法还是有一些规则的。不能使用RelativeLayout里面包一个RecyclerView，然后给RelativeLayout添加下拉刷新，这样的用法会出问题。
3. 更新日志
2016.7.14
1.适配了开源项目CanRecyclerView里面的CanRecyclerViewHeaderFooter，使RecyclerView支持自动加载。

2016.6.30
1.添加对CoordinatorLayout的支持。
2.自定义下拉上拉的背景颜色。

2016.4.7
1.解决下拉刷新中依然可下拉的bug。
