如何删除间距Horizo​​ntal GridLayoutManager recyclerview android

Question

我将recyclerview与grid layoutmanager一起使用 我没有添加ItemDecoration

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

但是在两行之间，有一行，我不添加它。我想删除它。
