I have a registration form in my application which I am trying to validate. I\'m facing some problems with my validation while validating the phone number and email fields.<

Answer 1

Try this

public class Validation {

    public final static boolean isValidEmail(CharSequence target) {
        if (target == null) {
        return false;
        } else {
        return android.util.Patterns.EMAIL_ADDRESS.matcher(target).matches();
        }
    } 

    public static final boolean isValidPhoneNumber(CharSequence target) {
        if (target.length()!=10) {
            return false;
        } else {
            return android.util.Patterns.PHONE.matcher(target).matches();
        }
    }

}
