Leanback VerticalGridFragment remove top spacing

Question

I am using VerticalGridFragment to display items in a grid-like layout I don\'t need to show search or title and I want the rows to start from top of the screen without any marg

Answer 1

I found a way to do it by overriding the VerticalGridPresenter of the VerticalGridFragment then getting the VerticalGridView, and setting top padding to a smaller value. In the CustomVerticalGridPresenter class (that extends VerticalGridPresenter), override this method:

@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 the VerticalGridFragment, assign the new CustomVerticalGridPresenter as following:

 CustomVerticalGridPresenter gridPresenter = new CustomVerticalGridPresenter();
    gridPresenter.setNumberOfColumns(NUM_COLUMNS);
    setGridPresenter(gridPresenter);
