General :: How To Map Accented Characters In Keyboard XML

I have to implement a simple custom soft-keyboard in my application and I want to show accented characters on the keyboard too.

These are: í, é, á, ű, ú, ő, ó, ü, ö

My question is how to map these in the keyboard xml? What are the key codes for these? I could not found them in the official KeyEvent document.

My current keyboard definition xml looks like this:

Code:
<Keyboard xmlns:android=""
android:keyWidth="10%p"
android:horizontalGap="0px"
android:verticalGap="0px"
