Grid Support

EpoxyAdapter can be used with RecyclerView's GridLayoutManager to allow EpoxyModels to change their span size. EpoxyModels can claim various span sizes by overriding int getSpanSize(int totalSpanCount, int position, int itemCount) to vary their span size based on the span count of the layout manager as well as the model's position in the adapter. EpoxyAdapter.getSpanSizeLookup() returns a span size lookup object that delegates lookup calls to each EpoxyModel.

int spanCount = 2;
GridLayoutManager layoutManager = new GridLayoutManager(getContext(), spanCount);
epoxyAdapter.setSpanCount(spanCount);
layoutManager.setSpanSizeLookup(epoxyAdapter.getSpanSizeLookup());
