Android的活动和观点 [英] Android Activities and Views

问题描述

当开发一个Android应用程序，有没有经验的时候，你应该停止改变布局，而是切换到新的活动规则？可能会影响哪些因素决定？

When developing an Android app, is there a rule of thumb for when you should stop changing layouts and instead switch to a new activity? What factors might influence the decision?

推荐答案

有没有硬性规定，但我有一些个人的：

There are no hard and fast rules, but I've got a few personal ones:

我主要是想我如何将用户使用后退按钮。在一个最佳的应用程序，自然用回要经过活动是我瞄准。每次用户可能要使用背，这应该是一个新的活动。当然，规则是为了打破，有时候你需要自己重载后退按钮来控制更复杂的界面。

I primarily think of how my users will use the back button. In an optimal app, the natural use of "back" to go through Activities is what I aim for. Each time a user might want to use back, that should be a new Activity. Of course, rules are meant to broken and sometimes you'll need to override the back button yourself to control a more complex interface.

此外，你应该不会被诱惑的setContentView（）再打电话。如果你很想重做页面的整个布局，也许你应该移动到一个新的活动代替。

Also, you shouldn't be tempted to call setContentView() again. If you are tempted to redo the entire layout of the page, maybe you should move to a new Activity instead.

我也想看看本指南。
