i'm not sure regardin of why it doesn't call what it should. First of all you should know that the code including the layouts and resources of the SDK are available to you online here:http:// android.git.kernel.org/?p=platform/frameworks/base.git;a=tree;f=core/ res/res;hb=donut-release2, this is a link to donut version resources.
the drop down and the view supposed to be different, one is for the spinner itself, for the single item that is displayed, the other is for the items in the list one the spinner is 'opened'. I urge you to take a look on the theme.xml and styles.xml and layout directory to see which of the layouts is used originally in the Spinner class and try to build your layouts from there. I had in my blod a zip with the source for 1.6, 2.1 and 2.2 though you can still view them online i think i' can find the link: http://www.devfrustrated.com/devBlog/browsing-android-source-code-in-eclipse/ in there in the end you got 3 zips, in most cases you can debug the code... in the evening i'll have some more time i might be able to look into it so you can send me the layouts :-) On Dec 6, 1:49 pm, Danny Schimke <[email protected]> wrote: > Hi poohtbear, > > I have no android source and I am using windows as development platform.
