+Colt McAnlis Supposing you have a FrameLayout containing 10 LinearLayout, where only one is visible per time. Each LinearLayout is a complex view, containing Button, EditText, TextView, ImageView, etc.

Thus changing the LinearLayout visibility, in order to show another item, would be a huge performance issue, correct?

Supposing you are using a list of @IntDef instead of Enum and they are used several types in switch-clauses in order to call (or not) some functions.

Would there be space reduction replacing replacing the switch-clauses by and strategy pattern implemented with Enums? Does it compensate the extra space consumed by the Enums?

In this article, Toptal engineer Stefan Varga challenges the popular notion of Java as a complicated platform for simple needs, and walks us through a step by step tutorial to building a simple MVC application with the Spring Framework and JPA.

Pessoal,

Eu criei o Google Developers Group no #Slack  e gostaria de convidar todos vocês :-)

Eu gostaria que uma ou duas pessoas de cada GDG fosse administrador, preferencialmente alguém ativo nos grupos, pro controle da comunidade ficar organizado mas não centralizado.

Quem quiser entrar, acesse https://gdgbrazil.slack.com

Fully testing user interactions is notoriously difficult. Front-end views aren't well-suited for traditional automated testing frameworks. Or they weren't, until React.js came along.

In today's article, Toptal guest author Swizec Teller shows us how React brings UI testing into the twenty-first century, with well-formed components and powerful testing tools.
