How to implement a simple Syntax highlighting method for edittext?

I am making an app that involves coding and I need edittext to recognize if the word typed was 'something' then depending if it is registered to be colored, it will color the word. Here is what I want to do, when the user is typing and types 'function' I want it to automatically highlight. Same goes to any other 'function' word, '()', ' " ', and many other words the user types.
