I didn't know how to call it but I'll try to explain what I mean -
How can I build an interface in android that can print some letters and then the user can pick some letters and form a word or a sentence.
Example: for those of you who know "Draw Something", when you have to guess what your friends drew, you have some scrambled letters from which you can pick some and form a sentence.
Here is an image of that: http://i.gyazo.com/033b5c9a2864c6a17d7445e0a1a3079e.png
How can I achieve that?
