RecyclerView没有像GridView那样有提供verticalSpacing属性，上StackOverflow找到了一种替代方法，代码如下
public class SpacesItemDecoration extends RecyclerView.ItemDecoration { private int mVerticalSpacing, mHorizontalSpacing; public SpacesItemDecoration(int verticalSpacing, int horizontalSpacing){ mHorizontalSpacing = horizontalSpacing; mVerticalSpacing = verticalSpacing; } @Override public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) { outRect.left = mHorizontalSpacing; outRect.right = mHorizontalSpacing; outRect.bottom = mVerticalSpacing; outRect.top = mVerticalSpacing; } }
在RecyclerView中使用
int verticalSpacing = getResources().getDimensionPixelSize(R.dimen.my_items_grid_vertical_spacing); int horizontalSpacing = getResources().getDimensionPixelSize(R.dimen.my_items_grid_horizontal_spacing); recyclerView.addItemDecoration(new SpacesItemDecoration(verticalSpacing, horizontalSpacing));
RecyclerView设置verticalSapcing等
