this(context.getResources().getDimensionPixelSize(itemOffsetId));
}
@Override
public void getItemOffsets(Rect outRect, View view, RecyclerView parent,
RecyclerView.State state) {
super.getItemOffsets(outRect, view, parent, state);
outRect.set(itemOffset, itemOffset, itemOffset, itemOffset);
}
}

Shopping.java
public class Shopping extends Fragment implements InstaPukkeiRecyclerViewAdapter.ItemClickListener {
InstaPukkeiRecyclerViewAdapter adapter;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.tab_shopping, container, false);
processRV(rootView);
return rootView;
}
private void processRV(View layout) {
RecyclerView recyclerView = (RecyclerView) layout.findViewById(R.id.shoppingRV);
int noOfColumns = 3;
recyclerView.setLayoutManager(new GridLayoutManager(getContext(), noOfColumns));
adapter = new InstaPukkeiRecyclerViewAdapter(getContext(), LogoIds.SHOPPING_SITE_LOGOS);
adapter.setClickListener(this);
recyclerView.setAdapter(adapter);
recyclerView.addItemDecoration(new ItemOffsetDecoration(getContext(), R.dimen.grid_horizontal_spacing));
}
}
