The id that is generated in the R class comes from a layout xml file... For example, in one of my programs I have a Gallery View that displays icons for currently running programs.. I have an xml file under /res/layout that contains the following:
<Gallery android:id="@+id/running_tasks_gallery" /> I then reference that particular view with: R.id.running_tasks_gallery Of course, this example is overly simplified and my actual Gallery tag contains much more than just the id... but the important elements are there. BTW... all this information is found in the Dev Guide. On Aug 27, 4:41 pm, ConquerWorm <[email protected]> wrote: > Hey, > > I am wondering if someone can explain this file to me and how it > works.
