在片段生命周期中调用REST服务的正确位置

Question

What is the best place in fragment lifecycle to call REST service for example to fill ListView with received data ? There are onCreateView , onActivityCreated and onResume . My first thought was to call network service as soon as possible, so on the end onCreateView , but i'm confused about this.

Answer 1

Just don't bind REST calls to your UI. You should split up UI and business logic responsible for getting and updating data. UI is just a facade so you shouldn't try to call any network services from UI. You can implement any of the patterns described by Virgil Dobjanshi in IO Talk
