I am not getting any view from the recycler, I did some debug and the constructor of the adapter is called with items on its list, also the method 

> 
> getItemCount()
> 
> 
> 

but none of the rest seem to be executed.
I´ve been wandering around stack looking for this problem and i found different approaches to a solution, problem is none worked out for me, maybe I am just missing something i can´t see.

I read somewhere that it could be because the recycler view is inside an scroll view, but the solution given did not worked for me

my custom adapter:

```
public class CircumstancesAdapter extends RecyclerView.Adapter<CircumstancesAdapter.CircumstancesViewHolder> {
List<CatalogRespModel> circumList;
Context mContext;

public CircumstancesAdapter(List<CatalogRespModel> list, Context context) {
    this.circumList = list;
    this.mContext = context;
}

@Override
public CircumstancesViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(mContext).inflate(R.layout.row_item_circumstances, parent, false);
    return new CircumstancesViewHolder(view);
}

@Override
public void onBindViewHolder(CircumstancesViewHolder holder, int position) {
    holder.tvCircum.setText(circumList.get(position).get_Descripcion());
}

@Override
public int getItemCount() {
    if(circumList != null) return circumList.size();
    else return 0;
}

public  class CircumstancesViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
    RadioButton rbCircum;
    TextView tvCircum;
    private Context context;

    public CircumstancesViewHolder(View itemView) {
        super(itemView);
        rbCircum = (RadioButton) itemView.findViewById(R.id.rb_circ);
        rbCircum.setOnClickListener(this);
        tvCircum = (TextView) itemView.findViewById(R.id.tv_circ);
        this.context = itemView.getContext();
    }

    @Override
    public void onClick(View v) {

    }
}

```

}

and in my onCreateView inside the fragment:

```
recyclerView = (RecyclerView) rootView.findViewById(R.id.rview_circumstances);
recyclerView.setNestedScrollingEnabled(false);
recyclerView.setHasFixedSize(true);
if(Catalogs.circumstancesArray.size() > 0){
        adapter = new CircumstancesAdapter(Catalogs.circumstancesArray, getContext());
        recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
        recyclerView.setAdapter(adapter);

    }

```

Note: I checked the List size and is greater than 0
