Not able to display items properly in recycler view (pagination issue)

When I try to load more items when the user had scrolled to the end, a progress dialog is displayed and removed and then again displayed and then more items are displayed but progress dialog is still not removed from recycler view. And sometimes progress dialog is removed but still, it takes more time to display more items in recycler view. I'm using firestore addOnSuccessListener to retrieve items from cloud firestore and adding it to an arraylist and then adding native ads advanced to that arraylist and add the data to the recycler adapter.

The short term answer: There's a lot going on in your code. If you just want to remove the loadingProgress, add a void viewsLoaded() method inside your LoadingViewHolder with progressbar.setVisibility(View.GONE), and inside onBindViewHolder method, on the if(myViewHolder instanceof LoadingViewHolder), call the viewsLoaded() method if viewHolder is not positioned as the last one on the Adapter.
The long term answer: If you want to enhance the performance, read about how to use DiffUtil.ItemCallback<> instead of using notifydatasetchanged(), which is used for simple small datasets. You have a list of objectData on your activity and another one on your adapter, read about using LiveData, databinding and MVVM pattern.

i suggest first of all you should get The linearLayoutManager inside The Scroll View Listener.
another suggestion is to not call movieListAdapter.notifyItemInserted(itemDatas.size() - 1); Async inside the Runnable because after you add a null into list The Adapter should be notify:
itemsData.add(null);
movieListAdapter.notifyItemInserted(itemsData.size() - 1);
another is in the line: itemDatas.remove(itemDatas.size()-1)
after you remove the item from list, The List size will decrease by one.
so this would be correct:
movieListAdapter.notifyItemRemoved(itemDatas.size());
i Hope these would help.

}
}
The ad has been initialized in MainActivity as:
MobileAds.initialize(this, getString(R.string.admob_app_id));
The code shows no error, and the SunList array (i.e. MENU_ITEM_VIEW_TYPE) is shown properly.
But the ad view (i.e. UNIFIED_NATIVE_AD_VIEW_TYPE) is showing no sign, not even as a place holder.
The fragment is called by the MainActivity as a viewpager (as generated by default tabbed activity) as:
SectionsPagerAdapter sectionsPagerAdapter = new SectionsPagerAdapter(this,
getSupportFragmentManager(), Lat, Long);
What I am doing wrong here?
NB: I am using firebase
Update
I suspect,
#Override
public int getItemViewType(int position) {
Object sunList = mSunsList.get(position);
if (sunList instanceof UnifiedNativeAd) {
System.out.println("==================Hello==============");
return UNIFIED_NATIVE_AD_VIEW_TYPE;
}
return MENU_ITEM_VIEW_TYPE;
}
is never true. The string has never printed
UPDATE Probably I have found the problem, but don't know how to solve it:
If I change the getItemViewType as:
public int getItemViewType(int position) {
Object sunList = mSunsList.get(position);
// if (sunList instanceof UnifiedNativeAd) {
if (position%3==0){
System.out.println("=================="+position+"==============");
return UNIFIED_NATIVE_AD_VIEW_TYPE;
}
return MENU_ITEM_VIEW_TYPE;
}
Then I get the error:
java.lang.ClassCastException: com.example.phocast.ui.main.SunSession cannot be cast to com.google.android.gms.ads.formats.UnifiedNativeAd
In this line in onBindViewHolder:
UnifiedNativeAd nativeAd = (UnifiedNativeAd) mSunsList.get(position);
Kindly help

you can load add when add show in recyclerview. not in activity

I think your native is not loading properly.
1) Make sure your ads inserting in recycleview. add log in all method and confirm it is loading properly.
2) During test app use testing ads id.
3) After LoadAds update recycleview with
adapter.notifyDataSetChanged();
4) There is no issue in below method.
#Override
public int getItemViewType(int position) {
Object sunList = mSunsList.get(position);
if (sunList instanceof UnifiedNativeAd) {
System.out.println("==================Hello==============");
return UNIFIED_NATIVE_AD_VIEW_TYPE;
}
return MENU_ITEM_VIEW_TYPE;
}
If still not getting ads please let me know.

RecycleView repeat action on one recycleview card on other

I am developing one quiz android application in which questions and their respective options and answer will be fetched from server and added to recycle view.
I have done coding of same and it is working except one problem that when i choose any option i turn its background green if it is right or i turn it to red if it is wrong but when i do same for any question same action is been transformed on other questions option in recycle view.
As i click on Option A
6th question from previous solved question have option A automatically selected

That is because Views are recycled by RecyclerView and you are setting background color to different color manually.
The solution is to set default color for background of your textFeed in BindViewHolder as:
textFeed.optionA_layout.setBackgroundColor(context.getResources().getColor(R.color.default_color));
textFeed.optionB_layout.setBackgroundColor(context.getResources().getColor(R.color.default_color));
textFeed.optionC_layout.setBackgroundColor(context.getResources().getColor(R.color.default_color));
textFeed.optionD_layout.setBackgroundColor(context.getResources().getColor(R.color.default_color));

How can I limit the number of native ads in recyclerview

How can I limit the number of native ads in recyclerview
I only want 5 native ads in first 100 lines in recyclerview (per every 20 lines).
My recyclerview have got 10000 row. It annoys the user on every 20 lines of ad output. So I want to limit the number of ads to 5. I made a lot of changes, but I could not.
Thank you in advance for your help
