How to use Android's getString() without violating basic OOD principles?

I need to use getString() from most o开发者_运维知识库f the modules in my application.

But for some strange reason, it is tied to Application or Context, so that means I need to pass to each and every class in my application, the Application reference as a parameter.

This clearly violates one of the most basic principles of object oriented design.

Is there a way around this?

The 'strange reason' is that since the string resources are tied to your application, there is no way to access them without some sort of handle to it (the Context). If most of your classes that are not activities need to access string resources, you might want to rethink your design a bit. A simple way to not depend on a Context is to load the strings and pass them to your classes in the constructor.

Yes, there is a workaround - if you happen to (or can) pass a View (any View-derived class) to the constructor, and you assign it to a data member, then you can access the string resources from anywhere in your class:

String str_via_res = yourView.getContext().getString(R.string.str_via_res);

Otherwise, you will have to pass a Context to every class that needs access to these string resources.

you can extend android.app.Application class to create a static method to pass on the context across all classes in your application.
