Changing Resources.StyledAttributes to TypedArray is enough to make it work.

Thanks for the easy-to-follow tutorial!

I was correct about Resources.StyledAttributes, but the second thing I thought was a mistake actually wasn’t. Passing in R.styleable.TextOnlyButton works – I actually mistyped the schema name in the XML. I managed to access android:text (which was in another namespace) by passing in the new int[]{android.R.attr.text}. This made me think that I needed to pass in an array of specific attributes rather than just using R.styleable.MyStyleableDeclaration. Of course, if you want to access attributes that aren’t defined in attrs.xml, then you will have to individually specify them.

Thanks Chris,

As you probably noticed, this tutorial is nearly 2 years old so what worked then probably changed. I’ll have to update this tutorial when I have the chance.

Your advice saves me some research though so much appreciated.

Cheers,
Anthony

Your code isn’t correct:

Resources.StyledAttributes a = getContext().obtainStyledAttributes(attrs,R.styleable.TextOnlyButton);

Returns a TypedArray rather than a Resources.StyledAtttributes. Additionally, you can’t just pass in R.styleable.TextOnlyButton as the numbers will be incorrect. You have to individually select the attributes you want (or call a function to subtract a constant from each value).

Hi Hanjo,

How can I use these customized attributes in styles.xml.

I’m getting error “attribute not found”

Thanks in advance.
