UI form validation library for Android
default
- Built on top of [Apache Commons Validator], a validation framework with proven track record on the web, desktop and mobile platforms.
- Declarative style validation using **Annotations**.
- **Extensible**, now allows Custom Annotations.
- **Synchronous** and **Asynchronous** validations, you don't have to worry about threading.
- Supports both BURST and IMMEDIATE modes.
- Works with **Stock Android Widgets**, no custom view dependencies.
- Isolates validation logic using rules.
- Compatible with other annotation-based libraries and frameworks such as [ButterKnife], [AndroidAnnotations], [RoboGuice], etc.,
Quick Start
-----------
**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 using
`Validator.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…
}
```
You will need a `Validator` and 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<ValidationError> errors)` - Called when there are validation error(s).
**Step 4 - Validate**
```java
registerButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
validator.validate();
}
});
```
The `Validator.validate()` call runs the validations and returns the result via appropriate callbacks on the `ValidationListener`. You can run validations on a background `AsyncTask` by calling the `Validator.validate(true)` method.

QUESTION
Cannot resolve symbol 'validator' while using android library
Asked 2019-Dec-27 at 10:04I want to use this library - https://github.com/ragunathjawahar/android-saripaar for form validation in my android app
I have included the dependencies
dependencies {
implementation 'com.mobsandgeeks:android-saripaar:2.0.3'
}
I also added this to the build.gradle project (app)
maven {
url "https://oss.sonatype.org/content/repositories/snapshots/"
}
I added all the codes required in the library but when I add this line of code:
validator = new Validator(this);
validator.setValidationListener(this);
......
validator.validate();
in super.OnCreate method in my activity
I get this error -
Cannot resolve symbol 'validator'
error: cannot find symbol variable validator
I have tried to clean project and rebuild project, its not working.
ANSWER
Answered 2019-Dec-27 at 10:04Check the proper example they have provided in github.
Validator validator = new Validator(this);
validator.setValidationListener(this);
validator.validate();
