Add a layout between Recycler View rows?

What I want to achieve is if I could detect a string within a recycler view item I would inflate something after it and before the next recycler view item is shown.

For example like you have CustomObject class. Take boolean (isCustomView) to add custom layout.

public class YourObject {
String customString ="";
boolean isCustomView=false;

public String getCustomString() {
    return customString;
}

public void setCustomString(String customString) {
    this.customString = customString;
}

public boolean isCustomView() {
    return isCustomView;
}

public void setCustomView(boolean customView) {
    isCustomView = customView;
}

}

Before sending data to Adapter make this changes to your data

 ArrayList<YourObject> yourObjectArrayList = new ArrayList<>();

    // Assume You have yourObjectArrayList with data filled

    // Take temp object 
    YourObject object = new YourObject();
    object.setCustomView(true);

    for (int i = 0; i < yourObjectArrayList.size(); i++) {
        if(yourObjectArrayList.get(i).getCustomString().equals("YOUR CUSTOM STRING")){

            // Adding a custom object before That Position
            if (i==0)
                yourObjectArrayList.add(0,object);
            else
                yourObjectArrayList.add(i-1,object);

            // Adding a custom object After That Position. Note here i+2 is a must
            yourObjectArrayList.add(i+2,object);
        }
    }
    // Add data to RecyclerView adapter & notify

Override getItemViewType() in recycler adapter

@Override
public int getItemViewType(int position) {
    return (yourObjectArrayList.get(position).isCustomView()) ? R.layout.your_custom_layout : R.layout.your_raw_layout;
}

Make below changes to override method onCreateViewHolder

 @Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView;


    if(viewType == R.layout.your_custom_layout){
        itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.your_custom_layout, parent, false);
    }
    else {
        itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.your_raw_layout, parent, false);
    }

    return new ViewHolder(itemView);

}

holder.dynamicLinearLayout.removeAllViews()
View view = LayoutInflater.from(context).inflate(R.layout.new_layout,null);
holder.dynamicLinearLayout.addView(view);

Try this on onBind

you can use the int getItemViewType(int); override method of the RecyclerView.Adapter<> class.

@Override
public int getItemViewType(int position){
    if (data.get(position).contains("Your string"))
        return 007; // any random integer you can use
    return super.getItemViewType(position);
}

And in the onCreateViewHolder method

@Override
public void onCreateViewHolder(ViewGroup parent, int viewType){
    if (viewType == 007){ // the view type you returned
        return #special_view // inflate your other layout here which you want to inflate if it contains your special string.
    else 
        return #normal_view;// inflate the normal view here and return
    }
}
