Simple way to Validate Form
Add maven jitpack.io and dependencies in build.gradle (Project) :
// build.gradle project
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
// build.gradle app/module
dependencies {
...
implementation 'com.github.gzeinnumer:AndroidFormValidation:version'
implementation 'com.google.android.material:material:1.2.0'
}- Material.io (docs)
First Step. Use MaterialComponents in your style :
<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
<!-- Customize your theme here. -->
</style>- Import and start validation with make and object from class
Validator.
//import com.gzeinnumer.afv.Validator;
TextInputLayout formNamaParent = findViewById(R.id.form_nama_p);
TextInputEditText formNama = findViewById(R.id.form_nama);
Button btnSubmit = findViewById(R.id.btn_submit);
Validator validator = new Validator();
//Add your form that you want to validate.
//Add `EditText` or `TextInputEditText` to `validator`.
validator.addView(formNama); // Default TypeForm.TEXT
btnSubmit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
boolean result = validator.validate();
//true if validate success
//false if validate failed
if (result) {
Toast.makeText(this, "Done", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(this, "Not Done", Toast.LENGTH_SHORT).show();
}
}
});- Delete
form viewfrom 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,
new Rule(TypeForm.EMAIL)
);
//example 2
//Add `EditText` or `TextInputEditText` with `TextInputLayout`.
validator.addView(
new FormInput(formNamaParent, formNama)
); // Default TypeForm.TEXT
//example3
//Add `EditText` or `TextInputEditText` with `TextInputLayout` and custom `Rule`.
validator.addView(
new FormInput(formNamaParent, formNama),
new Rule(TypeForm.TEXT)
);Read More Custom Rule

Put your EditText or TextInputEditText to removeView(view).
validatorRealTime.removeView(formNama);- Realtime message error when focus changed.
Put this code before build().
validatorRealTime.setEnableRealtimeMessageError(true); //default value is false- Add view with custom configuration
//example 1
//Add `EditText` or `TextInputEditText` with custom `Rule`.
validatorRealTime.addView(
formUserName,
new Rule(TypeForm.EMAIL)
