To add gradle dependency you need to open build.gradle (in your app folder,not in a project folder) then copy and add the dependencies there in the dependencies block;

2.Add HorizontalGridView in your layout

<app.com.tvrecyclerview.HorizontalGridView
        android:id="@+id/id_grid_first"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingLeft="45dp"
        android:paddingRight="45dp"
        android:paddingTop="20dp"
        android:clipChildren="false"
        android:clipToPadding="false" />

3.Set the presenter(adpter create child view)

public class RegularPresenter extends Presenter {
    RegularPresenter(Context context) {
        super(context);
    }
    @Override
    public View onCreateView() {
        ImageView view = new ImageView(getContext());
        view.setSelected(true);
        view.setFocusable(true);
        view.setLayoutParams(new ViewGroup.LayoutParams(423, 138));
        return view;
    }

    }
}

HorizontalGridView gridView = findViewById(R.id.id_grid_first);
gridView.addItemDecoration(new SpaceItemDecoration());
gridView.setNumRows(2);
GridObjectAdapter adapter = new GridObjectAdapter(new RegularPresenter(this));
gridView.setFocusZoomFactor(FocusHighlightHelper.ZOOM_FACTOR_SMALL);
gridView.setAdapter(adapter);
