Overview

HeaderAndFooterRecyclerView

Introduction

HeaderAndFooterRecyclerView is a RecyclerView solution that supports addHeaderView, addFooterView to a RecyclerView.

Through this library, you can implement RecyclerView's Page Loading by dynamically modify the FooterView's State, such as "loading", "loading error", "loading success", "slipping to the bottom".

How to Use It

Add HeaderView, FooterView

    mHeaderAndFooterRecyclerViewAdapter = new HeaderAndFooterRecyclerViewAdapter(mDataAdapter);
    mRecyclerView.setAdapter(mHeaderAndFooterRecyclerViewAdapter);
    mRecyclerView.setLayoutManager(new LinearLayoutManager(this));

    //add a HeaderView
    RecyclerViewUtils.setHeaderView(mRecyclerView, new SampleHeader(this));

    //add a FooterView
    RecyclerViewUtils.setFooterView(mRecyclerView, new SampleFooter(this));

LinearLayout / GridLayout / StaggeredGridLayout layout of RecyclerView paging load

mRecyclerView.addOnScrollListener(mOnScrollListener);

private EndlessRecyclerOnScrollListener mOnScrollListener = new EndlessRecyclerOnScrollListener() {

        @Override
        public void onLoadNextPage(View view) {
            super.onLoadNextPage(view);

            LoadingFooter.State state = RecyclerViewStateUtils.getFooterViewState(mRecyclerView);
            if(state == LoadingFooter.State.Loading) {
                Log.d("@Cundong", "the state is Loading, just wait..");
                return;
            }

            mCurrentCounter = mDataList.size();

            if (mCurrentCounter < TOTAL_COUNTER) {
                // loading more
                RecyclerViewStateUtils.setFooterViewState(EndlessLinearLayoutActivity.this, mRecyclerView, REQUEST_COUNT, LoadingFooter.State.Loading, null);
                requestData();
            } else {
                //the end
                RecyclerViewStateUtils.setFooterViewState(EndlessLinearLayoutActivity.this, mRecyclerView, REQUEST_COUNT, LoadingFooter.State.TheEnd, null);
            }
        }
    };

Attention

If you have already added a HeaderView for RecyclerView by RecyclerViewUtils.setHeaderView(mRecyclerView, view); , then call the ViewHolder 's getAdapterPosition()、getLayoutPosition(), ,the returned value will be affected by the addition of the HeaderView (the return position is the real position + headerCounter).

Therefore, in this case, please use: RecyclerViewUtils.getAdapterPosition(mRecyclerView, ViewHolder.this), RecyclerViewUtils.getLayoutPosition(mRecyclerView, ViewHolder.this).

Demo

setHeaderView 不支持 GridLayoutManager 吗？

        layoutManager = new GridLayoutManager(getContext(), 3);
        cateCommodityList.setLayoutManager(layoutManager);

        adapter = new CategoryAdapter(getContext(), categories);
//        cateCommodityList.setAdapter(adapter);

        mHeaderAndFooterRecyclerViewAdapter = new HeaderAndFooterRecyclerViewAdapter(adapter);
        cateCommodityList.setAdapter(mHeaderAndFooterRecyclerViewAdapter);

        View headerView = LayoutInflater.from(getContext()).inflate(R.layout.layout_cate_header, null);
        //add a HeaderView
        RecyclerViewUtils.setHeaderView(cateCommodityList, headerView);

结果 header 并不能出现在顶部，而是一个普通的item..

EndlessLinearLayoutActivity 横向加载有问题。

LinearLayoutManager lm = new LinearLayoutManager(this); lm.setOrientation(LinearLayoutManager.HORIZONTAL); mRecyclerView.setLayoutManager(lm);

如果设置为横向，中能加载一页数据。

RecyclerViewStateUtils

` public static LoadingFooter.State getFooterViewState(RecyclerView recyclerView) {

    RecyclerView.Adapter outerAdapter = recyclerView.getAdapter();
    if (outerAdapter != null && outerAdapter instanceof HeaderAndFooterRecyclerViewAdapter) {
        if (((HeaderAndFooterRecyclerViewAdapter) outerAdapter).getFooterViewsCount() > 0) {
            LoadingFooter footerView = (LoadingFooter) ((HeaderAndFooterRecyclerViewAdapter) outerAdapter).getFooterView();
            return footerView.getState();
        }
    }

    return LoadingFooter.State.Normal;
}`

你好，当我添加了一个不是LoadingFooter类型的FootView时，loadNextPage时调用 LoadingFooter footerView = (LoadingFooter) ((HeaderAndFooterRecyclerViewAdapter) 强制转换会出问题。
