Usage

    //the adapter is the original (这个 adapter 是原有的, 不改动它)
    LoadMoreWrapper.with(adapter)
        .setFooterView(...) // view or layout resource
        .setShowNoMoreEnabled(true) // enable show NoMoreView，default false
        .setListener(new LoadMoreAdapter.OnLoadMoreListener() {
             @Override
             public void onLoadMore(LoadMoreAdapter.Enabled enabled) {
                 // do something
                 // you can enabled.setLoadMoreEnabled(false) when do not need load more
             })
        .into(recyclerView);

in the original adapter: demo

    private static class AnotherAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

        private LoadMoreWrapper mWrapper;

        // code..

        @Override
        public void onAttachedToRecyclerView(RecyclerView recyclerView) {
            super.onAttachedToRecyclerView(recyclerView);

            mWrapper = LoadMoreWrapper.with(this);
            mWrapper.setListener(
                    new LoadMoreAdapter.OnLoadMoreListener() {
                        @Override
                        public void onLoadMore(LoadMoreAdapter.Enabled enabled) {
                            // do something
                        }
                    })
                    .setShowNoMoreEnabled(true)
                    .into(recyclerView);
        }

    }

方法名	备注
setLoadMoreEnabled(boolean enabled)	设置是否启用加载更多，默认 true
setShowNoMoreEnabled(boolean enabled)	设置全部加载完后是否显示没有更多视图，默认 false
getOriginalAdapter()	获取原来的 adapter
getFooterView	获取加载更多视图
getNoMoreView	获取没有更多视图

注意：当加载完全部后且已 setLoadMoreEnabled(false)，但如果由于生命周期或其他问题而导致 View 重建，mLoadMoreEnabled 依然为 true。这时候应该需要保存 mLoadMoreEnabled 的状态，如果是 ViewPager + Fragment，可以使用 setOffscreenPageLimit 进行解决。
