Estou tentando atualizar umViewHolder em umRecyclerView sem refazer a coisa toda. De acordo com os documentos, eu deveria fazer isso chamandoRecyclerView.Adapter.notifyItemChanged(int position, Object payload), Ondepayload é um objeto arbitrário que será passado paraRecyclerView.Adapter.onBindViewHolder(VH holder, int position, List<Object> payloads), onde poderei atualizar o ViewHolder.

Mas quando eu tento isso,onBindViewHolder sempre recebe uma lista vazia. Entre essas duas chamadas, a lista interna de cargas úteis é limpa. Após definir pontos de interrupção no código-fonte do RecyclerView, isso acontece devido a um retransmissão, que eventualmente chamaRecyclerView.ViewHolder.clearPayload()

Alguém mais conseguiu fazer isso funcionar? Isso é um bug na biblioteca de suporte ou é algo que eu fiz desencadeando uma retransmissão entre essas duas funções?

Aqui está o rastreamento de pilha para quando a carga útil é limpa:
