android - Multiple horizontalgridview with title

I want to create multiple horizontalgridview and each gridview have title above it. I already successfully made and the result is according what I want, but my app becomes so heavy.

My current view is like this:

I have a LinearLayout which contains a textview and a horizontalgridview. let's call it item_layout

I will dynamically add multiple item_layout to a custom LinearLayout (I named it SectionedView) in the main_layout. The code is roughly like this (not my real code):

public class SectionedView extends LinearLayout{
    ...
    public void setData(ArrayList<Object> object){
        for(Object o:object){
            View view = ...
            title = (TextView)view.findViewById(R.id.title);
            gridView = (GridView)view.findViewById(R.id.content); 
            title.setText(o.getTitle());
            adapter = new Adapter(o.getItems());
            gridView.setAdapter(adapter);
            addView(view);
        }
    }
    ...
}

That custom LinearLayout in the main_layout is located inside a ScrollView.

This is example of the main_layout

and this one is example of the LinearLayout inside main_layout(basically is the same with previous image).

My question is does anyone know better workaround for this, how, and why ? Thanks!

Edit: I am creating an Android TV app so I need to get focus for every item to navigate. but I have tried RecyclerView inside RecyclerView, the inner RecyclerView couldn't get focus :(
