This project derives from toshikurauchi/MaskedEditText, but it's been adapted for gradle build system and has additional features:
- filter allowed chars
- filter denied chars
- user can use chars from mask in his input (in original version of this library user couldn't use digit '7' in the '+7(XXX)XXX-XX-XX' pattern).
- You can keep hints even when user started typing.
So it allows you to use masks for phones, urls, etc.
