Android Saripaar v2
சரிபார் - sari-paar (Tamil for "to check", "verify" or "validate")
Android Saripaar is a simple, feature-rich and powerful rule-based UI form validation library for Android.
It is the SIMPLEST UI validation library available for Android.
Step 1 - Annotate your widgets using Saripaar Annotations
```java
@NotEmpty
@Email
private EditText emailEditText;
@Password(min = 6, scheme = Password.Scheme.ALPHA_NUMERIC_MIXED_CASE_SYMBOLS)
private EditText passwordEditText;
@ConfirmPassword
private EditText confirmPasswordEditText;
@Checked(message = "You must agree to the terms.")
private CheckBox iAgreeCheckBox;
```
The annotations are self-explanatory. The @Order
annotation is required ONLY when performing ordered validations usingValidator.validateTill(View)
and Validator.validateBefore(View)
or in IMMEDIATE
mode.
Step 2 - Instantiate a new Validator
```java
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Code…
validator = new Validator(this);
validator.setValidationListener(this);
// More code…
}``
Validator
You will need aand a
ValidationListener` for receiving callbacks on validation events.
Step 3 - Implement a ValidationListener
```java
public class RegistrationActivity extends Activity implements ValidationListener {
// Code…
@Override
public void onValidationSucceeded() {
Toast.makeText(this, "Yay! we got it right!", Toast.LENGTH_SHORT).show();
}
@Override
public void onValidationFailed(List<ValidationError> errors) {
for (ValidationError error : errors) {
View view = error.getView();
String message = error.getCollatedErrorMessage(this);
// Display error messages ;)
if (view instanceof EditText) {
((EditText) view).setError(message);
} else {
Toast.makeText(this, message, Toast.LENGTH_LONG).show();
}
}
}
}``
onValidationSucceeded()
-- Called when all your views pass all validations.
onValidationFailed(List errors)` - Called when there are validation error(s).
-
Step 4 - Validate
```java
registerButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
validator.validate();
}
});``
Validator.validate()
Thecall runs the validations and returns the result via appropriate callbacks on the
ValidationListener. You can run validations on a background
AsyncTaskby calling the
Validator.validate(true)` method.
If you are looking for country-specific annotations, checkout the Saripaar X project. The extensions project is in its early stages and needs contributors. Feel free to contribute.

file.
-keep class com.mobsandgeeks.saripaar.** {*;}
-keep @com.mobsandgeeks.saripaar.annotation.ValidateUsing class * {*;}
