First Step. Use MaterialComponents in your style :

<stylename="AppTheme"parent="Theme.MaterialComponents.Light.NoActionBar">
<!-- Customize your theme here. -->
</style>

Validation Form

• Import and start validation with make and object from class Validator.

//import com.gzeinnumer.afv.Validator;TextInputLayoutformNamaParent = findViewById(R.id.form_nama_p);
TextInputEditTextformNama = findViewById(R.id.form_nama);
ButtonbtnSubmit = findViewById(R.id.btn_submit);
Validatorvalidator = newValidator();
//Add your form that you want to validate.//Add `EditText` or `TextInputEditText` to `validator`.validator.addView(formNama); // Default TypeForm.TEXTbtnSubmit.setOnClickListener(newView.OnClickListener() {
@OverridepublicvoidonClick(Viewv) {
booleanresult = validator.validate();
//true if validate success//false if validate failedif (result) {
Toast.makeText(this, "Done", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(this, "Not Done", Toast.LENGTH_SHORT).show();
}
}
});

• Delete form view from validate process

Put your EditText or TextInputEditText to removeView(view).

validator.removeView(formNama);

• Add view with custom configuration

//example 1//Add `EditText` or `TextInputEditText` with custom `Rule`.validator.addView(
formNama,
newRule(TypeForm.EMAIL)
);
//example 2//Add `EditText` or `TextInputEditText` with `TextInputLayout`.validator.addView(
newFormInput(formNamaParent, formNama)

//true if validate success//false if validate failedbtnSubmit.setEnabled(isDone);
}
});
//Trigger with onClickListenerbtnValidate.setOnClickListener(newView.OnClickListener() {
@OverridepublicvoidonClick(Viewv) {
booleanresult = validatorRealTime.getResult();
//true if validate success//false if validate failedif (result){
Toast.makeText(SecondActivity.this, "Success", Toast.LENGTH_SHORT).show();

formUserName,
newRule(TypeForm.EMAIL)
