I ran into the same issue. The method call is not seen by the
compiler. Use an object of the class "Context" to make that method
call.
If you are continuing the HelloGallery Example, there is a Context
object already being used called mContext.
So my code looks like this:
public ImageAdapter2(Context c)
{
mContext = c;
TypedArray a = mContext.obtainStyledAttributes
(R.styleable.default_gallery);
mGalleryItemBackground = a.getResourceId
(R.styleable.default_gallery_android_galleryItemBackground, 0);
a.recycle();
}
After this change the example worked fine.
Hope this helps,
