Answer 1

You have change input type like..

 android:inputType="phone"

Answer 2

You can not. This is your android keyboard app and you cant change it. The keyboard settings can be modified in the android settings. But obviously it depends on the user, not the developer.

The only way I think it will allow you to do that is that you include in your app a fake numeric keypad as a layer (Similar to the keyboard that appears when you have to type the pin of the app of your bank). However, I don't think this is worth it. With...

android:inputType = "numberSigned"

you are already blocking the user from entering letters or other characters, even if they change their keyboard.
