java - lambda 回调多个接口的写法是怎样的

new ProgressSubscriber>(activity) {
       @Override
       public void onError(Throwable e) {
       getTokenListener.onError();
       }

       @Override
       public void onNext(BaseResponseBody tokenBaseResponseBody) {
 getTokenListener.onSucess(tokenBaseResponseBody.result.content.token);
      }
}

怎么转成

(activity)->{
         (Throwable e)->{
          getTokenListener.onError();
         }

         (BaseResponseBody tokenBaseResponseBody)->{
         getTokenListener.onSucess(tokenBaseResponseBody.result.content.token);
       }
 }
