Re: [android-developers] findViewById returning NULL
Thanks No I only have a single landscape layout. The biggest baffle is that is works and then does not work All I do is re-type the findViewByID part and in the layout xml re-type the android:id line and 95% that fixes it. But this case where it does and does not work, while I am working on another section is frustrating to say the least Thanks again On Mar 25, 2011, at 3:13 PM, B Lyon wrote: Not sure if it applies in your case, but do you have a separate layouts for landscape and portrait and that view is defined in only one of them?

Re: [android-developers] findViewById returning NULL
pretty weird eclipse didn't insert an import to (something I forgot).R.* did it? Seems like it will do that sometimes. Of course, you can do a Project--Clean, but it may come back anyway in this case let me know when you figure it out what it is On Sat, Mar 26, 2011 at 8:19 AM, New Developer secur...@isscp.com wrote: Thanks No I only have a single landscape layout.

Re: [android-developers] findViewById returning NULL
What version of eclipse are you using? And on what operating system? I have read that eclipse versions 3.6, sometimes gives some kind of weird errors, like the one you are describing... Just to be on the safe side, you could donwload any 3.5.X eclipse version and check if this still happens...

Not sure if it applies in your case, but do you have a separate layouts for landscape and portrait and that view is defined in only one of them? I think the eclipse android plugin might not catch this kind of thing, and so you wouldn't find out until runtime that it wasn't in both layouts.
