String text question

Why when we add a new screen of the app clicking the button, we do don't have to change the "Did you know?" text, it always there, what tells Android studio to keep showing it on every new screen?

you arent adding a new screen each time you press the button. its the same screen every time, you just change the text of the button and change the color of the background. the textView that says "Did you know" never goes away, its always on the screen because we never change the screen.

Ohh now I understand, thanks a lot!, now when I run the app the emulator lets me edit the textView that has the fun fact, is that normal?

probably dont want the text view to be editable. in the xml file for the layout you can add some attributes to your edit text node to make it not editable:

<YourTextView>
        android:clickable="false" 
        android:cursorVisible="false" 
        android:focusable="false" 
        android:focusableInTouchMode="false">
</YourTextView>
