Removing the default interval in the recycler view layout

Question

I am using the StaggeredGridLayout manager to view the recycler

 mStaggerGridLayoutManager = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager .VERTICAL); 

Now I want to remove the spacing between columns and rows. Something like this image, but with only two columns.

You need to play with margin. Not filling out.

StaggeredGridLayoutManager sets the default value to "30dp" for each grid item.

It can be changed as follows:

 class StaggeredListDecoration extends RecyclerView.ItemDecoration { public StaggeredListDecoration() { } @Override public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) { super.getItemOffsets(outRect, view, parent, state); BaseCard.CARD_TYPE viewType = (BaseCard.CARD_TYPE)view.getTag(); ((StaggeredGridLayoutManager.LayoutParams) view.getLayoutParams()).leftMargin = 0; ((StaggeredGridLayoutManager.LayoutParams) view.getLayoutParams()).rightMargin = 0; ((StaggeredGridLayoutManager.LayoutParams) view.getLayoutParams()).topMargin = 0; ((StaggeredGridLayoutManager.LayoutParams) view.getLayoutParams()).bottomMargin= 0; } }
