MVVM项目结构整理

基于Kotlin/Dagger2/RxJava/RxAndroid/Retrofit/Okhttp/ViewModel/LiveData等来实现

  1. 框架结构整理

MVVM – Model View ViewModel 的方式来实现

                next = nextPage,
                nextKey = { if (it.list.isEmpty()) it.pageIndex else it.pageIndex + 1 },
                dataTransformation = { it.list },
                loadInitial = {
                    client.getOrderBySortPerson(1).toObservable()
                },
                loadAfter = { params, key ->
                    client.getOrderBySortPerson(key).toObservable()
                },
                pipeErrorsTo = { error(it) }
            )
