Hi all, I'm a beginner in Android development and I'm looking for some guides. I've tried also to read some ones in the Android developer site, but in this <http://developer.android.com/training/basics/firstapp/starting-activity.html> one I can see, in a void function, they use a findViewById to get a EditText element, but I don't know where is it, because it's not been declared in any layout file. Can you help me please? Thank you a lot.
