这是正常/建议在Android应用超过一个活动？在我看来，这在某种程度上奇怪有内部应用程序的数据交换

Is it normal/recommended to have more than one activity in Android app? in my opinion, it's somehow strange to have this model of data exchange inside application

推荐答案

还有就是Android开发者页面上的介绍：

There is an overview on the Android developer page:

要总结一下，这取决于你的数据要通过什么类型的。但一般来说，如果可能的话，我会选择意图，因为他们是速度快，专为这一点。

To summarize it, it depends on what type of data your going to pass. But generally speaking, if possible, I would choose Intents, because they are fast and built for that.

<一个href="http://thedevelopersinfo.word$p$pss.com/2009/10/15/passing-data-between-activities-in-android/">Here是说明如何使用意图活动之间传递数据的例子。

Here is an example that explains how to pass data between activities using Intents.
