Victor, I am not entirely sure. But I can suggest a couple of experiments to debug. May be inheriting a View directly is too simplisitic. Try inheriting a TextView first. And if it works then you can look at what other base methods of the "View" you will need to inherit.
Take a look at this item from the docs http://developer.android.com/training/custom-views/custom-drawing.html to see what other methods you need to override. Also if you are intending to use some custom attributes you may want to look at some detailed notes I have gathered at http://satyakomatineni.com/item/4169 This goes into how attrs.xml and declare styleables work. Also let me know what you find.
