Answer 1

You need create new class with name CustomVerticalGridPresenter and put followig code in it.

public class CustomVerticalGridPresenter extends VerticalGridPresenter {

    VerticalGridView gridView;

    CustomVerticalGridPresenter(int zoom, boolean val){
        super(zoom, val);
    }

    @Override
    protected void initializeGridViewHolder(ViewHolder vh) {
        super.initializeGridViewHolder(vh);
        gridView = vh.getGridView();
        int top = 20;//this is the new value for top padding
        int bottom = gridView.getPaddingBottom();
        int right = gridView.getPaddingRight();
        int left = gridView.getPaddingLeft();
        gridView.setPadding(left,top,right,bottom);
    }
}

Then in verticalgridfragment class use

CustomVerticalGridPresenter videoGridPresenter = new 
CustomVerticalGridPresenter(ZOOM_FACTOR, false);

instead of

VerticalGridPresentervideoGridPresenter = new VerticalGridPresenter(ZOOM_FACTOR, false);
