validation

How to use:

    edtNotBlankRequired = (EditText) findViewById(R.id.edt_name);
    edtEmailRequired = (EditText) findViewById(R.id.edt_email);
    edtPhoneRequired = (EditText) findViewById(R.id.edt_phone);
    edtNumberRequired = (EditText) findViewById(R.id.edt_number);
    edtLengthRequired = (EditText) findViewById(R.id.edt_text_length);
    edtInDateRangeRequired = (EditText) findViewById(R.id.edt_future);

And validate:

    VerifierBuilder builder = new VerifierBuilder();
    builder.registerVerifier(new RequiredVerifier(edtNotBlankRequired, "Your name"));
    builder.registerVerifier(new EmailVerifier(edtEmailRequired, "Email"));
    builder.registerVerifier(new PhoneVerifier(edtPhoneRequired, "Phone"));
    builder.registerVerifier(new NumberVerifier(edtNumberRequired, "Your ID card no."));
    builder.registerVerifier(new LengthVerifier(edtLengthRequired, "Address", 4, 300));
    builder.registerVerifier(new DateRangeVerifier(edtInDateRangeRequired, "Register date",
        DateTimeUtil.COMMON_DATE_FORMAT, "05/20/2016", "05/20/2017"));
    boolean verify = builder.verify();
    if(verify){
        Toast.makeText(this, "Validate success!", Toast.LENGTH_LONG).show();
    }
