Question

I have an Adnroid library project that defines XML resource.

Let’s use a selector drawable as an example (but I have problems with strings, styles, etc).

LibProject/res/drawable/button_selector.xml … defines a selector

LibProject/res/layout/view.xml …. uses the selector, with no problems

 `<TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/sign_up_fly_buttons"
        android:background="@drawable/button_selector"/>`

Then I want to refer to it in a layout in my App

AppProject/res/layout/view.xml …

`<TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/sign_up_fly_buttons"
        android:background="@drawable/button_selector"/>`

But in the App it won’t compile or let me reference it.
I’ve tried various namespace incantations to try and refer to it with no luck…

Any ideas?

Addition:
I have read that the full-form for such references is:
@[packagename:]type/id
and if you leave out the package name then the package where this resource file is used.

This an example would be:
@com.mylibrary:drawable/button_selector

But it doesn’t work for me! There must be something wrong with my library setup/import?

My library is in a separate Eclipse Android project, marked as a Library project, and is referenced from my app as a “Dependent Project” and code is built and links in fine.

Answer 1

OK, found the problem!

In Eclipse, in my Project Properties -> Java Build Path -> “Projects” ‘tab’ I had the library project added.

BUT, I also had to add it to Project Properties -> Android -> Library area as Library Project.

I had done this for others, but had forgotten to do it here.

Thanks to all who tried to figure out my mistake.

Now the resources are merged in correctly and I can refer to them using the “short-form” format without the package name.
