Form validation library for Android?

Question

Is there any mature form validation API / library for Android? I\'ve found http://code.google.com/p/android-binding/ but it seems that is under heavy development.

Answer 1

This will be the simple and mature way to validate the input texts or forms:

private EditText et_first_name;
et_first_name = (EditText)findViewById(R.id.et_first_name);
et_first_name = (EditText)findViewById(R.id.et_first_name);
first_name.matches("^(?i)(?=.{1,20}$)([A-Za-z]+[A-Za-z0-9-_.]*$)"); // use the regex expression inside brackets and returns the error status .
