问题 I am trying to make a class that uses the Jackson to deserialize POJO's.

What are the specific benefits of using DI on Android?

阅读更多关于 What are the specific benefits of using DI on Android?

What are the specific benefits or advantages of using a dependency injection framework for Android, like Dagger , Transfuse or RoboGuice ? For example, what kind of apps would benefit the most from using DI? is there more of a performance advantage, or is it more on the ease of extending an app, or even more about making it testable? One of the reasons for asking this is to gauge if an app I'm developing would actually benefit from it or not much. Since I intend the app to be serious at some point, testability and ease of extension would be great, even if costly to use (more time to setup,

Guice @Provides Methods vs Provider Classes

问题 I'm working on a fairly large project that has a lot of injections. We're currently using a class that implements Provider for each injection that needs one, and they mostly have one line get methods. It's starting to get annoying to create a new class every time I need a new provider.

Android & RoboGuice - Inject views on Fragment?

阅读更多关于 Android & RoboGuice - Inject views on Fragment?

问题 I have a fragment that I need to display on the screen. I want to be able to use InjectView to inject my UI elements. InjectView works fine on activities because the view (xml) is set during onCreate , however on fragments the view is set on onCreatView . So is there a way to use InjectView on fragments? I know that I could use findViewbyId to find each element, but I rather use InjectView public class ProfileFragment extends RoboDialogFragment { @InjectView(R.id.commentEditText) protected
