问题 New to Android here, so I apologize if this is a simplistic question. I am attempting to use a switch based on string resources in my XML.

How to reference a string in strings.xml of an Android library in code?

阅读更多关于 How to reference a string in strings.xml of an Android library in code?

问题 To reference string foo in strings.xml (in res\values) of an app project, one can simply use getString(R.string.foo) getString is a method of Context. Suppose an Android library has a string foo in its strings.xml. How can it be used in a method of the library? Edited: It has been suggested to pass a reference of Context to the library method so getString() can be used. Since it is a context of an app's project, there is potential conflict that can be illustrated as following: Suppose: The

Switch between reference and value preview of string resources in the xml editor

阅读更多关于 Switch between reference and value preview of string resources in the xml editor

Any idea? Couldn't find any reference to this in the help file. 回答1: Click and bring the

阅读更多关于 Robolectric throws Resources$NotFoundException when trying to access resource in raw folder

问题 When I try to access a raw resource I receive an android.content.res.Resources$NotFoundException: Unable to find resource ID #0x7f060000 error. The resource is a .bks certificate, used for server validation. It is stored on the res/raw folder. The most awkward thing is that when I copied the certificate (and the validation architecture) to a fresh project (that I built just to test this), it worked! I'm using nenick's custom runner, so Robolectric can correctly find the folders for manifest,
