私のアプリケーションでページ分割の概念を実装しています。細かいプログレスバーが非表示になっている場所が非表示になっていないことが表示されています続きを表示
問題がある：がある場合のみ4または5には、プログレスバーが、私はどのようにすることができ、より多くのデータ
を取得するためにスクロールしたときにのみプログレスバーが来なければならないことのように実行しないべき進展し続けるで記録修正する
final RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(mContext);
recyclerView.setLayoutManager(mLayoutManager);
recyclerView.setItemAnimator(null);
parishNewsAdapter = new ParishNewsAdapter(recyclerView, listParishNews, mActivity, mContext);
recyclerView.setAdapter(parishNewsAdapter);
parishNewsAdapter.setOnLoadMoreListener(new OnLoadMoreListener() {
@Override
public void onLoadMore() {
finalList.add(null);
parishNewsAdapter.notifyItemInserted(finalList.size() - 1);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
ArrayList<ParishNewsModel> mList = new ArrayList<>();
finalList.remove(finalList.size() - 1);
parishNewsAdapter.notifyItemRemoved(finalList.size());
index = index + 15;
int end = index + 1;
mList = tableHelper.getParishNews(end);
if (mList.size() == 0) {
ParishNewsAdapter.LoadingViewHolder.progressBar.setVisibility(View.GONE);
}
parishNewsAdapter.addObjectToList(mList);
parishNewsAdapter.notifyDataSetChanged();
parishNewsAdapter.setLoaded();
}
}, 1000);
}
});
This is where i just call the adapter where the progress should show when i swipe to see more data
here is my adapter
