### Beside from using the provided Rules, you can create your own Rule by extending Rule (Create as many as you want)
```kotlin
class CustomRule : Rule("Value doesn't match 'ABC'") {
override fun validate(value: String?): Boolean {
if (value == null) {
throw NullPointerException()
}
return value == "ABC"
}
}
```
### Add it to your Activity class
```kotlin
// Username
// Input: [email protected]
val usernameInput = findViewById(R.id.layout_username)
val usernameValidation = validation(usernameInput) {
conditions {
+and(errorMessage = "Does not match 'And' condition") {
+email(errorMessage = "")
+endsWith(keyword = ".com", errorMessage = "")
}
+or(errorMessage = "Does not match 'Or' condition") {
+minimumLength(minLength = 8, errorMessage = "")
+contain(keyword = "hello", errorMessage = "")
}
}
}
// Password
// Input: 12345abc
val passwordInput = findViewById(R.id.layout_password)
val passwordValidation = validation(passwordInput) {
rules {
+notEmpty(errorMessage = "Input is empty")
+minimumLength(minLength = 8, errorMessage = "Must have at least 8 characters")
}
}
```
### Mode
```kotlin
validator(applicationContext) {
/* Set your mode here, by default is CONTINUOUS */
mode = Mode.SINGLE
}
```
| Single | Continuous |
| --- | --- |
|  |  |
### Validate the input field
```kotlin
// Order of the values on the success callback follow the sequence of your Validation object
validator(applicationContext) {
mode = Mode.SINGLE
listener = object : Validator.OnValidateListener {
override fun onValidateSuccess(values: List) {
Log.d("MainActivity", values.toTypedArray().contentToString())
Toast.makeText(
applicationContext,
"Validate successfully",
Toast.LENGTH_LONG
).show()
}
override fun onValidateFailed(errors: List) {
Log.e("MainActivity", errors.toTypedArray().contentToString())
}
}
validate(usernameValidation, passwordValidation)
}
```
* Introduce Validator library
## Testing
