The items added multiple times into the RecyclerView with pagining

I am working on android app with java. and now I have to do messaging activities. I use RecyclerView to display the messages items. Also my messages Api is work with pagining, every time I send the last id and the server return the previous 10 messages.(Page size is 10). For filling the RecyclerView I use an Adapter but my problem is, that the item is added multiple times into the RecyclerView.
I will put my activity code and the adapter code
My Activity:
public class ConversationsActivity extends RootActivity implements ConversationsAdapter.ConversationOnClickHandler {
RetrofitBuilder rB = new RetrofitBuilder();
IApi service = rB.retrofit.create(IApi.class);
String authorization;
RecyclerView rv;
ConversationsAdapter adapter;
ProgressBar progressBar;
LinearLayoutManager layoutManager;
//declare it as global var for future cancel refresh
private SwipeRefreshLayout swipeLayout;
boolean wasSwiped;
// initialise loading state
boolean mIsLoading, mIsLastPage = false;
// amount of items you want to load per page
final int pageSize = 10;
int mCurrentPage =0;
int lastId;
boolean f;
int p =1;
private AlphaAnimation buttonClick = new AlphaAnimation(1F, 0.7F);

any help or advice?
And thankyou

in your addAll() function on ConversationsAdapter class
int lastIndex = mConversation.size() - 1;
mConversation.clear();
mConversation.addAll(newList);
notifyItemRangeInserted(lastIndex, newList.size());
this should do the trick

Original List in adapter not updating once filtered something

When I scroll my list it follows the pagination as expected.
But when I open my search view and type something and reset the editText and try to load next list it does not update in adapter unless I swipe my fragments or hide the searchview.
In both the cases i set my edittext to null so it gets updated on that call thats where i think but need your help.
I did lots of search yesterday but unfortunately found nothing. Hope I'll find help here. Thanks

If you need any extra information please let me know.

Call feedsAdapter.notifyDataSetChanged(); after updating the List. You are calling notifyDataSetChanged() before the list gets updated when the edittext is reset. Your filter method updates the list in the adapter but you are doing notifyDataSetChanged before the list is getting updated. You need to do it after

I am not able to load more pages using Endless RecyclerView ScrollListener

I am using Recyclerview to achieve endless recyclerview scroll listener. Now it loading only page = 1 and page = 2 while scrolling but it not loading another pages, and I added EndlessRecyclerViewScrollListener class from github.

Try this you will get perfect result.
int pastVisiblesItems, visibleItemCount, totalItemCount;
recyclerView.addOnScrollListener(new
RecyclerView.OnScrollListener() {
#Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
if (dy > 0) {
visibleItemCount = layoutManager.getChildCount();
totalItemCount = layoutManager.getItemCount();
pastVisiblesItems = layoutManager.findFirstVisibleItemPosition();
if (loading && totalItemCount >= (pastVisiblesItems + 50)) {
userPage++;
callAccountStatementAPI(userPage);
Log.v("...", "Last Item Wow !");
//Do pagination.. i.e. fetch new data
}
}
}
});

Below the code will work But this code totally wrong way actually u are calling every api hit to creating new adapter and adding list. See more pagination examples and change it.. See reference here.
Write a method in Adapter Class:
public void addMoreItems(ArrayList<AccountStatementModel> newItems){
androidVersions.addAll(newItems);
}
Write Activity:
case ACCOUNT_STATEMENT:
androidVersions = (ArrayList<AccountStatementModel>) response.body();
AccountPaginationAdapter adapter = new AccountPaginationAdapter(getApplicationContext(), androidVersions);
androidVersions.addAll((Collection<? extends AccountStatementModel>) response.body());
adapter.addMoreItems(androidVersions);
adapter.notifyItemRangeInserted(adapter.getItemCount(), androidVersions.size()-2);
recyclerView.setAdapter(adapter);
break;
}

I want develop android application for one website. I read website posts from json and show its in RecyclerView every 10 posts and when user scrolling on RecyclerView show more 10 post and go to end! in this project i use okHTTP v3 and RecyclerView!
I want gonna put a button and when click on this button, load new data (if there was new data).

When use this method LoadData(); in button action, not load new data just copy fist 10 post and load again this first 10 post!
How can i fix it and when click on Button click action, load new data ?
Attention : Please don't give me negative points, help me and i really need you helps! thanks all <3

I dont understand your code but in your AsyncTask this method should like that :
public void getMainDataInfo(Context context,int page) {
mContext = context;
new getInfo().execute(ServerAddress + "page="+page);
}
In your code you always getting page=1, there is no paging parameter in method

You can use SwipeRefreshLayout for this.

Cannot scroll up because of endless scroll - setOnScrollListener

I'm making app with Swipe down to refresh functionality. And it works fine.
Here the code I used:
swipeRefreshLayout = (SwipeRefreshLayout) v.findViewById(R.id.swipe_container);
swipeRefreshLayout.setOnRefreshListener(this);
swipeRefreshLayout.setColorSchemeColors(Color.CYAN, Color.MAGENTA, Color.YELLOW, Color.BLUE, Color.CYAN);
mRecyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() {
#Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
}
#Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
int topRowVerticalPostion = (mRecyclerView == null || mRecyclerView.getChildCount() == 0) ? 0 : mRecyclerView.getChildAt(0).getTop();
swipeRefreshLayout.setEnabled(dx == 0 && topRowVerticalPostion >= 0);
}
});
Then I added Swipe up to load more functionality. But after that I noticed, that I cannot scroll up to previous item, when before I scrolled down to N-th item. When I tried scroll up, it call RefreshLayout.
Code I used (https://gist.github.com/ssinss/e06f12ef66c51252563e):
mRecyclerView.setOnScrollListener(new EndlessRecyclerOnScrollListener(mLayoutManager) {
#Override
public void onLoadMore(int current_page) {
Log.d("SCROLL PAST UPDATE", "You hit me");
//maintain scroll position
int lastFirstVisiblePosition = ((LinearLayoutManager) mRecyclerView.getLayoutManager()).findFirstCompletelyVisibleItemPosition();
((LinearLayoutManager) mRecyclerView.getLayoutManager()).scrollToPosition(lastFirstVisiblePosition);
loadMore(articles);
}
});

solved by deleting this:
mRecyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() {
#Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
}
#Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
int topRowVerticalPostion = (mRecyclerView == null || mRecyclerView.getChildCount() == 0) ? 0 : mRecyclerView.getChildAt(0).getTop();
swipeRefreshLayout.setEnabled(dx == 0 && topRowVerticalPostion >= 0);
}
});
And add this to mRecyclerView.setOnScrollListener(new EndlessRecyclerOnScrollListener(mLayoutManager) {
#Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
}
#Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
int topRowVerticalPostion = (mRecyclerView == null || mRecyclerView.getChildCount() == 0) ? 0 : mRecyclerView.getChildAt(0).getTop();
swipeRefreshLayout.setEnabled(dx == 0 && topRowVerticalPostion >= 0);
}

if you use this library 'com.lzy.widget:view-core:0.2.1' and integration with SwipeRefresh add this code, work for me.
scrollableLayout.setOnScrollListener(new HeaderViewPager.OnScrollListener() {
#Override
public void onScroll(int currentY, int maxY) {
pagerHeader.setTranslationY(currentY / 2);
int topRowVerticalPostion = (rvRestaurant == null || rvRestaurant.getChildCount() == 0) ? 0 : rvRestaurant.getChildAt(0).getTop();
mSwipeRefreshLayout.setEnabled(currentY == 0 && topRowVerticalPostion >= 0);
}
});
