How to put banner in recyclerview

I was able to put the banner in recylerview, but it is overlapping one of the items, it replaces one, instead of getting between them, does anyone know how to fix it?
I'm pulling an api, I do not know if that makes any difference. I searched for several tutorials, but I did not find it, what I need to do is add an admob native banner.

Edited answer to ignore the banner click event
Issue is with getItemCount. As you are adding ads in between items you also need to increase the count as well. So that the number of items not get replaced with ad item.
public static final int ITEM_PER_AD = 3;
#Override
public int getItemCount() {
int itemCount = capitulos.size();
itemCount += itemCount / ITEM_PER_AD ;
return itemCount;
}
Accordingly you also need to exclude positions for ads, to get the original item position.
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
if (!(holder instanceof MyViewHolder)) {
return;
}
int itemPosition = position - position / ITEM_PER_AD ; // need to adjust to get the list item position excluding ads
}
Below code is about to ignore click event for the ads.
#Override
public void onItemClick(View view, int position) {
if (position>1 && position % ITEM_PER_AD == 0) {
return;
}
// rest of the code keep as it is.
}

attempting to use incompatible return type

Can someone help me with this error that I keep getting? The program that I'm trying to implement admob banner ad between items in recyclerview. every thing is ok but still this one error that blocked me from go on.

The return type needs to be whatever ViewHolder type you declared for your adapter class.
For example, from the Android RecyclerView example page:
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {
// ^^^^^^^^^^^^^^^^^^^^^^
// It should return this type ^
public static class MyViewHolder extends RecyclerView.ViewHolder {
// your adapter
}
#Override
public MyAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent,int viewType) {
// Note: returns MyAdapter.MyViewHolder, not RecyclerView.ViewHolder
}
}
In your case, you have
public class RecipeAdapter extends RecyclerView.Adapter<RecipeAdapter.ViewHolder>
which means your onCreateViewHolder has to return RecipeAdapter.ViewHolder not RecyclerView.ViewHolder.
There is a separate issue too, which is that you have two ViewHolder types in the same adapter. To do this, you would need to change the ViewHolder type that your RecyclerView is based on to the generic type (RecyclerView.ViewHolder).
Please review this question, it has good answers for how to do this.

mAdapter.notifyItemChanged(i) crashes on Android

I am trying to update a single TextView in my RecyclerView. I tried using mAdapter.notifyItemChanged(1); but this crashes the app and I can't figure out why. Calling mNumbersList.setAdapter(mAdapter); works fine.
Here is my adapter:
public class GreenAdapter extends RecyclerView.Adapter<GreenAdapter.NumberViewHolder> {
private final String TAG = GreenAdapter.class.getSimpleName();
private int mNumberItems;
public GreenAdapter(int numberOfItems) {
mNumberItems = numberOfItems;
}
#Override
public NumberViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
Context context = viewGroup.getContext();
int layoutIdForListItem;
if (viewType==1) { layoutIdForListItem = R.layout.first; } else { layoutIdForListItem = R.layout.number_list_item; }
LayoutInflater inflater = LayoutInflater.from(context);
boolean shouldAttachToParentImmediately = false;
View view = inflater.inflate(layoutIdForListItem, viewGroup, shouldAttachToParentImmediately);
NumberViewHolder viewHolder = new NumberViewHolder(view);
return viewHolder;
}
#Override
public int getItemViewType(int position) {
int First;
switch (position) {
case 0: First=1;
break;
default:
First = 0;
}
return First;
}
#Override
public void onBindViewHolder(NumberViewHolder holder, int position) {
Log.d(TAG, "#" + position);
holder.bind(position);
}
#Override
public int getItemCount() {
return mNumberItems;
}
class NumberViewHolder extends RecyclerView.ViewHolder {
TextView listItemNumberView;
public NumberViewHolder(View itemView) {
super(itemView);
listItemNumberView = (TextView) itemView.findViewById(R.id.TV1);
}
void bind(int listIndex) {
//String[] messages = getResources().getStringArray(R.array.messageArray);
//listItemNumberView.setText(messages[listIndex]);
switch (listIndex) {
case 0: if (setStatusError) {Status="Cannot connect to eve-central";} listItemNumberView.setText(Status);
break;
case 1: listItemNumberView.setText(Buy[listIndex-1]+" "+Sell[listIndex-1]);
break;
case 2: listItemNumberView.setText(Buy[listIndex-1]+" "+Sell[listIndex-1]);
break;
default:listItemNumberView.setText(String.valueOf(listIndex));
}
}
}
}
EDIT: Nevermind I am stupid. I had a handler that does this but it already starts before the RecyclerView is called...

SetExpandAdapter in RecycleViewAdapter

I have RecycleView List with an ExpandableLinearLayout ( i use a third party library). In my ExpandableLinearLayout I have a ListView, with an custom ArrayAdapter.
I set my Adapter in the RecycleViewAdapter and submit one ArrayList that contains 4 ArrayLists and the position from the onBindViewHolder() method , too fill the different sections in the RecycleView.
I pass the data in the correct section but i get only the first element of each ArrayList. I Log some stuff and the problem is the position from the getView method in my ArrayAdapter is always 0..
I search and played around a bit but i didnt found a solution.. I hope somebody can help..

final RadioButton itemcheck = (RadioButton) item_view

}
itemcheck.setChecked(true);
}

}
public interface OnCheckedRadioButon {
void onCheckedButton(Details pr);
}
class ViewHolder {
RadioButton radiobutton;
TextView listview_name;
}
}
It is working but if I click on another position of the listview then the previous radiobutton position is not unchecked.I want to uncheck all the previous ones and mark only one at a time.
Any help will be appreciated.

Use POJO classes (Setter or Getter) to manage this type of condition. Use boolean variable in that class and change its values according to the position true or false.
POJO Class Like :
public class CheckListSource {
public boolean isSelected;
public boolean isSelected() {
return isSelected;
}
public void setSelected(boolean selected) {
isSelected = selected;
}
}
In your adapter :
private ArrayList<CheckListSource > itemsData;
public ChildListAdapter(Activity activity, ArrayList<ChildListResponse> baseResponse) {
this.itemsData = baseResponse;
this.activity = activity;
}
In BindViewHolder Like :
viewHolder.checkParentView.setTag(itemsData.get(position));
viewHolder.checkParentView.setOnClickListener(checkedListener);
private View.OnClickListener checkedListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
CheckListSource childListResponse = (CheckListSource ) v.getTag();
if (childListResponse.isSelected())
childListResponse.setSelected(false);
else
childListResponse.setSelected(true);
notifyDataSetChanged();
}
};

Use a boolean array in your Activity. Each boolean value corresponds to a RadioButton.
If a RadioButton is checked, set its boolean value to true, and set all other boolean values in the array to false.
In the getView() of your Adapter, call your_radio_button.setChecked(your_boolean_array[position]).
Once the boolean array is modified, call your_adapter.notifyDataSetChanged().

Checkout this it works for me..
public class ProgramAdapter extends ArrayAdapter<KeyInformation> {
private final String TAG = "ProgramAdapter";
private List<KeyInformation> mList;
private Context mContext;
private LayoutInflater mInflater;
private int mSelectedPosition = -1;
private RadioButton mSelectedRB;

public ProgramAdapter(Context context, List<KeyInformation> objects) {
super(context, R.layout.program_item, objects);
mContext = context;
mList = objects;
mInflater = ( LayoutInflater ) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mUserApllication = Settings.System.getString(mContext.getContentResolver(),
Settings.System.PROGRAMMABLE_KEY_ACTION);
}
#Override

if (convertView == null) {
holder = new ViewHolder();
convertView = mInflater.inflate(R.layout.program_item, parent, false);
holder.mImageView = (ImageView) convertView.findViewById(R.id.icon);
holder.mTextView = (TextView) convertView.findViewById(R.id.text);
holder.mSeparator = (TextView) convertView.findViewById(R.id.title_separator);
holder.mRadioButton = (RadioButton) convertView.findViewById(R.id.radioBtn);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.mRadioButton.setOnClickListener( new View.OnClickListener() {
#Override
public void onClick(View view) {
if(position != mSelectedPosition && mSelectedRB != null){
mSelectedRB.setChecked(false);
}
mUserApllication ="";
mSelectedPosition = position;
mSelectedRB = (RadioButton) view;
}
});
String userApp = mList.get(position).packageName;
if(mUserApllication.equals(userApp)) {
mSelectedPosition = position;
}
if (mSelectedPosition != position) {
holder.mRadioButton.setChecked(false);
} else {
holder.mRadioButton.setChecked(true);
mSelectedRB = holder.mRadioButton;
}
holder.mImageView.setImageDrawable(mList.get(position).icon);
holder.mTextView.setText(mList.get(position).lable);
if (position == 5) {
holder.mSeparator.setVisibility(View.VISIBLE);
} else {
holder.mSeparator.setVisibility(View.GONE);
}
return convertView;
}
public int getmSelectedPosition () {
return mSelectedPosition;
}
private static class ViewHolder {
