You need to use input filter and set it on Edit Text with setFilters method

You need to look at the reference. EditTest inherits from TextView: http://developer.android.com/reference/android/widget/TextView.html

There you can add an TextChangedListener:
addTextChangedListener(TextWatcher watcher)

Then you test for your special characters and remove them if they are found
