Answer 1

You need to associate a TextWatcher to your EditText, and then, check in onTextChanged() if the character added was a number. You could use a regular expression for that :

if(s.matches("[0-9]")){
  doYourStuffMethod();
}

You can also use the Matcher class from Android SDK which is an helper for this kind of stuff.
