Get resource ID (R.string.name) of string value from Android attr in custom view

My application has a custom view, styled by attrs.xml entry:

<resources>
    <declare-styleable name="MyView">
        <attr name="title" format="reference" />
        <attr name="image" format="reference" />
    </declare-styleable>
</resources>

In my custom view, I need to retreive the resource ID of resource specified as title in attrs.xml, but I can only retreive the content of string specified as title. Fo far, I've tried using:

attrs.getAttributeResourceValue(R.styleable.MyView_title, 0)

And

getSourceResourceId(R.styleable.MyView_title, 0)

But in both cases, the returned value is the default 0.

I've tries the same approach with other types of attributes, and for example, Drawable ID can be easilly retrieved by:

getResourceId(R.styleable.MyView_image, 0)

Is there any way to check what R.string was provided in XML?

getResourceId(R.styleable.MyView_title, 0) doesn't work? – jana Nov 28 '20 at 16:03
No, it only returns `0`, the specified default value – ikurek Nov 30 '20 at 11:33
can you add the xml for the layout? – jana Nov 30 '20 at 11:55
it seems as though you are setting the title value with a string, rather than a reference.. – jana Nov 30 '20 at 12:03
