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));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).
