HeaderAndFooterRecyclerView

Introduction: HeaderAndFooterRecyclerView 是支持 addHeaderView、 addFooterView、分页加载数据的 RecyclerView。它可以对 RecyclerView 控件进行拓展,给 RecyclerView 增加 HeaderView、FooterView,并且不需要对你的 Adapter 做任何修改。同时,通过修改 FooterView State,可以动态为 FooterView 赋予不同状态(加载中、加载失败、滑到最底等),可以实现 RecyclerView 分页加载数据时的 loading/theEnd/NetWorkError 效果。

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).
