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".

• 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);
            }
        }
    };

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).

• Add HeaderView, FooterView

• Support for ply loading of the LinearLayout layout RecyclerView

• Support for paging loads of GridLayout layout RecyclerView

• Supports paging loads of StaggeredGridLayout layout RecyclerView

• The page load fails when the GridLayout layout is RecyclerView
