How remove spacing Horizontal GridLayoutManager recyclerview android

Question

I use recyclerview with grid layoutmanager I don't add ItemDecoration

GridLayoutManager gridLayoutManager = new GridLayoutManager(TestResultActivity.this, 4, GridLayoutManager.HORIZONTAL, false);
            gridLayoutManager.setAutoMeasureEnabled(true);
            grid.setLayoutManager(gridLayoutManager);

But between two rows, have a row and I don't add it. I want to remove it.
