I think the link supplied by TDS is broken. To see your threads and posts, simply click on your forum name to the right of your avatar. You will be sent to a page where you can select your threads or posts. To see someone else's threads, type their forum name in the customary search box.

I guess the link expires after a while.
There are many ways to search though. I usually do the way Mahares suggests.
Another way is to use this link: Android Development Forum - Basic4android - Search Forums
