Native Ads overlapped RecyclerView items

I try to implement Native Ads inside RecyclerView. The ad should be placed every 3 items in recycler view. I use a native ads template. Ads are loaded but they have overlapped items in RecyclerView. I try couple of solution but they didn't work. Please help me, thank you in advance.
Below is the code for Adapter class:
public class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
Context c;
ArrayList<Model> models;
private static final int CONTENT_TYPE = 1;
private static final int AD_TYPE = 0;
public MyAdapter(Context c, ArrayList<Model> models) {
this.c = c;
this.models = models;
}
#Override
public int getItemViewType(int position) {
if (position % 3 == 0) {
return AD_TYPE;
} else {
return CONTENT_TYPE;
}
}
class adViewHolder extends RecyclerView.ViewHolder {
TemplateView adTemplate;
public adViewHolder(#NonNull View itemView) {
super(itemView);
adTemplate = itemView.findViewById(R.id.native_ad);
}
}
#NonNull
#Override
public RecyclerView.ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
if (viewType == AD_TYPE) {
adViewHolder myadViewHolder = new adViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.item_ads, null, false));
return myadViewHolder;
} else {
MyHolder myHolder = new MyHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.single_list_item, null, false));
return myHolder;
}
}
#Override
public void onBindViewHolder(#NonNull final RecyclerView.ViewHolder holder, int position) {
if (getItemViewType(position) == CONTENT_TYPE) {
((MyHolder) holder).mTitle.setText(models.get(position).getTitle());
((MyHolder) holder).mDescription.setText(models.get(position).getDesc());
((MyHolder) holder).mImageView.setImageResource(models.get(position).getImage());
} else if (getItemViewType(position) == AD_TYPE) {
final AdLoader adLoader = new AdLoader.Builder(c, "ca-app-pub-3940256099942544/2247696110")
.forUnifiedNativeAd(new UnifiedNativeAd.OnUnifiedNativeAdLoadedListener() {
#Override
public void onUnifiedNativeAdLoaded(UnifiedNativeAd unifiedNativeAd) {
NativeTemplateStyle styles = new NativeTemplateStyle.Builder().build();
TemplateView template = ((adViewHolder) holder).adTemplate;
template.setStyles(styles);
template.setNativeAd(unifiedNativeAd);
}
})
.withAdListener(new AdListener() {
#Override
public void onAdFailedToLoad(int errorCode) {
}
})
.withNativeAdOptions(new NativeAdOptions.Builder()
.build())
.build();
adLoader.loadAd(new AdRequest.Builder().build());
}
}
#Override
public int getItemCount() {
return models.size();

Showing ads in RecyclerView paging with Firestore database

I am working with RecyclerView which support pagination with Firestore database.I want to showing into 10 items recylcerview an Ads,i try serveral times without succes,help me please to find the right code.
Here is my code of pagination.
//Initialize FirebasePagingOptions
DatabasePagingOptions<Pubs> options = new DatabasePagingOptions.Builder<Pubs>()
.setLifecycleOwner(this)
.setQuery(mDatabase, config, Pubs.class)
.build();
//Initialize Adapter
mAdapter = new FirebaseRecyclerPagingAdapter<Pubs, PubsViewHolder>(options) {
#Override
public int getItemViewType(int position)
{
if (position % 5 == 0)
return AD_TYPE;
return CONTENT_TYPE;
}
#NonNull
#Override
public PubsViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
return new PubsViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.item_pub, parent, false));
}
#Override
protected void onBindViewHolder(#NonNull PubsViewHolder holder,
int position,
#NonNull Pubs model) {
holder.setItem(model);
}

this is a full example to how to use multi type recyclerview with custom adapter with Model and Ads Type
and for paging issue you have to handle it outside adapter class it can be more easier.
public class SiteAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private List<SiteModel> dataList;
private Context context;
private static final int AD_TYPE = 1;
private static final int CONTENT_TYPE = 2;
public SiteAdapter(Context context) {
this.context = context;
dataList = new ArrayList<>();
}
#Override
public int getItemViewType(int position) {
if (dataList.get(position) == null)
return AD_TYPE;
return CONTENT_TYPE;
}
public List<SiteModel> getDataList() {
return dataList;
}
#NonNull
#Override
public RecyclerView.ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View v = null;
RecyclerView.ViewHolder vh = null;
if (viewType == AD_TYPE) {
v = LayoutInflater.from(parent.getContext()).inflate(R.layout.ad_view_item, parent, false);
vh = new AdViewHolder(v);
} else {
v = LayoutInflater.from(parent.getContext()).inflate(R.layout.site_list_item, parent, false);
vh = new SitesViewHolder(v);
}
return vh;
}
#Override
public void onBindViewHolder(#NonNull final RecyclerView.ViewHolder holder, int position) {
holder.setIsRecyclable(false);
if (getItemViewType(position) == CONTENT_TYPE) {
} else {
AdViewHolder adViewHolder = (AdViewHolder) holder;
AdRequest request = new AdRequest.Builder().build();
adViewHolder.adView.loadAd(request);
}
}
#Override
public int getItemCount() {
return dataList.size();
}
public void add(SiteModel siteModel, int i) {
dataList.add(siteModel);
notifyItemInserted(i);
}
public void add(List<SiteModel> moreData) {
dataList.addAll(moreData);
notifyDataSetChanged();
}
public void updateItem(String desc, boolean isFavourites, int adapterPosition) {
dataList.get(adapterPosition).setDesc(desc);
notifyItemChanged(adapterPosition);
}
public class SitesViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
public SitesViewHolder(View itemView) {
super(itemView);
}
#Override
public void onClick(View v) {
if (clickListener != null) {
switch (v.getId()) {
}
}
}
private class AdViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

How to add dividers, spacers, or header with text to a recylerview

I've got a RecylerView that is displaying a list of data. I need to add dividers or spacers that I need to add two Dividers or spacers too that I can add text to as shown in the image below(with the text DEFAULT or OTHER).
*NOTE Headers are in the image below with the text "DEFAULT" and another that says "OTHER".
The CC's shown are drag and drop items but i don't want the "spaces or headers" marked as default and other to be moved.
I've started adding the divider as shown in the code below but I cannot figure out how to add text.
#Override
public void onViewCreated(#NonNull View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
ButterKnife.bind(this, view);
LinearLayoutManager mAdapterLayoutManager = new LinearLayoutManager(context);
recyclerView.setLayoutManager(mAdapterLayoutManager);
billingMethodRecyclerViewAdapter = new BillingMethodRecyclerViewAdapter(context, billingMethods, paymentService, ListPaymentMethods.this );
billingMethodRecyclerViewAdapter.setMasterpassService(masterpassService);
billingMethodRecyclerViewAdapter.setChoosePaymentMode(choosePaymentMode);
DividerItemDecoration itemDecor = new DividerItemDecoration(context, mAdapterLayoutManager.getOrientation());
recyclerView.addItemDecoration(itemDecor);
recyclerView.setAdapter(billingMethodRecyclerViewAdapter);
billingMethodRecyclerViewAdapter.clear();
if (!choosePaymentMode) {
setupSwipeListener(billingMethodRecyclerViewAdapter);
}
if (!BuildConfig.SHOW_AVAILABILITY_INRIX) {
parkmobileProAd.setVisibility(View.GONE);
}
if (getArguments() != null) {
isAddPaymentZoneDetails = getArguments().getBoolean(AddPaymentActivity.ADD_PAYMENT_FROM_ZONE_DETAIL);
}
}
and the xml for the recylcerview

This is it. This was able to solve your problem.
I am not able to explain you the complete code, I will take some time in future definitely and explain it.

public class MyAdapter extends RecyclerView.Adapter<MyViewHolder> {
// other methods..
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
// initialize your other views
if (your condition){
// display header
}else{
// hide header
}
}
}
You can do some thing like this by adding header view to the item and displaying for the required set and making it gone for un necessary items.

Simply coming towards what you need, just add an empty view with layout_height="1dp" and background="#bcbcbc" like:
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#bcbcbc"/>
it'll get a line drawn for you, use it as a divider, while for making format difference just use a change text size for texts.
Hope it'll help you.

How to create Chatting UI using Recycler with two view types but get nothing in the screen

I'm trying to get chatting data from the server and show it. I've created two xml, one for receiver and other for sender. I also tried to implement the logic in adapter class but when I call the API I got a blank screen.
Please help me to figure out the problem.

Sticky Header RecyclerView with multiple ArrayLists

I am implementing sticky header with RecyclerView. I have three sections (i.e 3 sticky headers) and they are working fine.Now I have taken three arraylists inside each section, I have initialized these list in my adapter and I am trying to get data of these lists on basis of header id inside onBindViewHolder. But it is not giving me the full list,just one string from each list (i.e under first section--data on first position of mylist,,,under second section-- data on second position of mylist1 ---under third section-- data on third position of mylist2)
Please Help !!
Code in Context:
StickyTestAdapter
public class StickyTestAdapter extends RecyclerView.Adapter<StickyTestAdapter.ViewHolder> implements
StickyHeaderAdapter<StickyTestAdapter.HeaderHolder> {
private Context mContext;
private ArrayList<String> mylist;
private ArrayList<String> mylist1;
private ArrayList<String> mylist2;
private static int countposition;
private String HEADER_FIRIST="HEADER_FIRIST";
private String HEADER_SECOND="HEADER_SECOND";
private String HEADER_THIRD="HEADER_THIRD";
public StickyTestAdapter(Context context) {
prepareData();
prepareData1();
prepareData2();
this.mContext=context;
}

Question is quite old. But that code looks complicated to read, personally I try to not reinvent what others did quite well by creating libraries.
GitHub is full of source that you can import. Some examples: FlexibleAdapter, FastAdapter, Epoxy and others.
I have build the first one, but you can try the others as well.
With mine, having multiple views and headers with sections is quite easy, I point here the wiki page where I define the section and how to initialize it.
Along with this feature, you have a lot more functionalities that makes your life easier.

I divide arraylist into 3 section based on alphabet like contactlist.
For that i use SectionedRecyclerViewAdapter
MainActivity.java
public class MainActivity extends AppCompactActivity {
private SectionedRecyclerViewAdapter sectionAdapter;
#Override
public View onCreate(Bundle savedInstanceState) {
setContentView(R.layout.activity_main);
sectionAdapter = new SectionedRecyclerViewAdapter();
for(char alphabet = 'a'; alphabet <= 'z';alphabet++) {
List<String> contacts = getContactsWithLetter(alphabet);
if (contacts.size() > 0) {
sectionAdapter.addSection(new ContactsSection(String.valueOf(alphabet), contacts));
}
}
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
recyclerView.setAdapter(sectionAdapter);
return view;
}
#Override
public void onResume() {
super.onResume();
if (getActivity() instanceof AppCompatActivity) {
AppCompatActivity activity = ((AppCompatActivity) getActivity());
if (activity.getSupportActionBar() != null)
activity.getSupportActionBar().setTitle(R.string.nav_example1);
}
}
private List<String> getContactsWithLetter(char letter) {
List<String> contacts = new ArrayList<>();
for (String contact : getResources().getStringArray(R.array.names_)) {
if (contact.charAt(0) == letter) {
contacts.add(contact);
}
}
return contacts;
}
private class ContactsSection extends StatelessSection {
String title;
List<String> list;
ContactsSection(String title, List<String> list) {
super(new SectionParameters.Builder(R.layout.section_ex1_item)
.headerResourceId(R.layout.section_ex1_header)
.build());
this.title = title;
this.list = list;
}
#Override
public int getContentItemsTotal() {
return list.size();
}
#Override
public RecyclerView.ViewHolder getItemViewHolder(View view) {
return new ItemViewHolder(view);
}
#Override
public void onBindItemViewHolder(RecyclerView.ViewHolder holder, int position) {
final ItemViewHolder itemHolder = (ItemViewHolder) holder;
String name = list.get(position);
itemHolder.tvItem.setText(name);
itemHolder.imgItem.setImageResource(name.hashCode() % 2 == 0 ? R.drawable.ic_face_black_48dp : R.drawable.ic_tag_faces_black_48dp);
itemHolder.rootView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getContext(), String.format("Clicked on position #%s of Section %s", sectionAdapter.getPositionInSection(itemHolder.getAdapterPosition()), title), Toast.LENGTH_SHORT).show();
}
});
}
#Override
public RecyclerView.ViewHolder getHeaderViewHolder(View view) {
return new HeaderViewHolder(view);
}
#Override
public void onBindHeaderViewHolder(RecyclerView.ViewHolder holder) {
HeaderViewHolder headerHolder = (HeaderViewHolder) holder;
headerHolder.tvTitle.setText(title);
}
}
private class HeaderViewHolder extends RecyclerView.ViewHolder {
private final TextView tvTitle;
HeaderViewHolder(View view) {
super(view);
tvTitle = (TextView) view.findViewById(R.id.tvTitle);
}
}
private class ItemViewHolder extends RecyclerView.ViewHolder {
private final View rootView;
private final ImageView imgItem;
private final TextView tvItem;
ItemViewHolder(View view) {
super(view);
rootView = view;
imgItem = (ImageView) view.findViewById(R.id.imgItem);
tvItem = (TextView) view.findViewById(R.id.tvItem);
}
}
}

use structure similar to
public class MultiArray<T> {
List<ItemGroup> lists = new ArrayList<>();
public void addList(String headerText, List<T> list) {
lists.add(new ItemGroup(headerText, list));
}
public int itemCount() {
int count = 0;
for (ItemGroup group : lists) {
count += group.count();
}
return count;
}
public T getItem(int position) {
int count = 0;
for (ItemGroup group : lists) {
if (count + group.count() >= position) {
return group.item(position - count);
}
count += group.count();
}
return null;
}
public int getGroupIndex(int position) {
int count = 0;
int groupIndex = 0;
for (ItemGroup group : lists) {
if (count + group.count() >= position) {
return groupIndex;
}
count += group.count();
groupIndex++;
}
return -1;
}
public String getHeaderText(int position){
int count = 0;
for (ItemGroup group : lists) {
if (count + group.count() >= position) {
return group.headerText;
}
count += group.count();
}
return "";
}
class ItemGroup {
public final String headerText;
public final List<T> list;
public ItemGroup(String headerText, List<T> list) {
this.headerText = headerText;
this.list = list;
}
public int count() {
return list.size();
}
public T item(int position) {
return list.get(position);
}
}
}
you can optimize it for faster performance
