Galaxy Tab 10.1 automatically select EditText when activity is created

I just had a galaxy tab 10.1, (the last galaxy tab) and it is running Android 3.1. I installed the app I created and it is containing a lot of EditText to fill. The problem is the following :

When an activity is created, if there's EditText on the screen, it automatically open the virtual keyboard to fill the first EditText. Even if I didn't clicked on it. Same problem when I scroll a screen : if I scroll, even if I don't click on an EditText, it select one of the screen and open the keyboard automatically.

It's really annoying because it's always doing that.

Did somebody already encountered the same problem ? If so, how to correct it ?

Thank you very much !

If I remember correctly, creating an empty LinearLayout before the EditText consumes the focus.
