Step 1. Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}Step 2. Add the dependency
dependencies {
compile 'io.github.anderscheow:validator:1.1.3'
}1.1.3 (Newest)
-
Input can be any object, previously restrict to String (Along with proper validation with different object)
-
Added more test cases to validate input
1.1.2
- Updated ALPHA_NUMERIC_SYMBOLS regex on PasswordRule
1.1.1
- Fixed bug where overloading the constructor with errorMessage or errorRes does not override the default value
1.1.0
-
Added ability to add conditions (And or Or)
-
Added mode of validation (Single or Continuous)

1.0.3

1.0.2
-
Added success and failed callback instead of just success callback
-
Success callback return list of EditText values (Order by sequence of Validation object(s))
1.0.1
-
Added some common rules (LengthRule, MinRule, MaxRule, RegexRule etc.)
-
Able to use String as error message
1.0.0
- Introduce Validator library
- LengthRule
- MaxRule
- MinRule
- NotEmptyRule
- NotNullRule
- RegexRule
- AlphanumericRule
- DigitsRule
- EmailRule
- PasswordRule
- FutureRule
- PastRule
- CreditCardRule
- ContainRule
- NotContainRule
- EqualRule
- NotEqualRule
Beside from using the provided Rules, you can create your own Rule by extending BaseRule (Create as many as you want)
public class CustomRule extends BaseRule {
@Override
public boolean validate(Object value) {
if (value == null) {
throw new NullPointerException();
}
return value.equals("ABC");
}
// You can use this to return error message
@NonNull
@Override
public String errorMessage() {
return "Value doesn't match 'ABC'";
}
// or use this to return error message as StringRes
@Override
public int errorRes() {
return R.string.error_not_match;
}
}// Username
// Input: [email protected]
TextInputLayout usernameInput = findViewById(R.id.layout_username);
final Validation usernameValidation = new Validation(usernameInput)
.addRule(new NotEmptyRule() {
// You can also override the default error message
@Override
public int errorRes() {
return R.string.error_not_empty;
}
// Use either errorRes() or errorMessage()
// Note: errorRes() has higher priority
@NonNull
@Override
public String errorMessage() {
return "Value is empty";
}
})
.addRule(new CustomRule());
// You can also use the constructor to override errorRes or errorMessage
final Validation usernameValidation = new Validation(usernameInput)
.addRule(new NotEmptyRule(R.string.error_not_empty));
final Validation usernameValidation = new Validation(usernameInput)
.addRule(new NotEmptyRule("Value is empty"));
// Password
// Input: 12345abc
TextInputLayout passwordInput = findViewById(R.id.layout_password);
final Validation passwordValidation = new Validation(passwordInput)
.addRule(new NotEmptyRule())
.addRule(new PasswordRule(PasswordRegex.ALPHA_NUMERIC))
.addRule(new MinRule(8));// And Condition
final Validation usernameWithConditionValidation = new Validation(usernameInput)
.add(new And().add(new EmailRule()));
// Or Condition
final Validation usernameWithConditionValidation = new Validation(usernameInput)
.add(new Or().add(new MinRule(5)).add(new MaxRule(10)));
// Both
final Validation usernameWithConditionValidation = new Validation(usernameInput)
.add(new And().add(new EmailRule()))
.add(new Or().add(new MinRule(5)).add(new MaxRule(10)));Validator.getInstance(getApplicationContext())
/* Set your mode here, by default is CONTINUOUS */
.setMode(Mode.CONTINUOUS));| Single | Continuous |
|---|---|
 |
 |
// Order of the values on the success callback follow the sequence of your Validation object
Validator.getInstance(getApplicationContext())
.setMode(Mode.CONTINUOUS))
.validate(new Validator.OnValidateListener() {
@Override
public void onValidateSuccess(List<String> values) {
Log.d("MainActivity", Arrays.toString(values.toArray())); // Output: [[email protected], 12345abc]
Toast.makeText(getApplicationContext(), "Validate successfully", Toast.LENGTH_LONG).show();
}
@Override
public void onValidateFailed() {
}
},
usernameValidation, passwordValidation);I have added unit testing for Rules and Conditions, soon will provide test code on Validation and Validator, please check it out underTest code
