You can register validation on any view which extends TextView component. SheenValidator has default error message like Email is required, email is not valid, etc if you dont use errorListener, but if you want to custom error message you can do it like this ...

Usage with Error Listener to custom Error

sheenValidator.setOnErrorValidatorListener { list ->
    list.forEach {
         when(it.id){
             R.id.txt_username -> til_username.error = "Oops!... looks like your username is not valid"
             R.id.txt_password -> til_password.error = "Hmm... password is required"
                }
            }
        }

Usage with Annotation

   lateinit var sheenValidator: SheenValidator

   @RegisterValidation(ValidationType.REQUIRED, 
   ValidationType.EMAIL)
   lateinit var txtUsername: TextInputEditText
   @RegisterValidation(ValidationType.REQUIRED)
   lateinit var txtPassword: TextInputEditText
   ...
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        ...
        txtUsername = findViewById(R.id.txt_email)
        txtPassword = findViewById(R.id.txt_password)

        sheenValidator = SheenValidator(this)
        sheenValidator.setOnValidatorListener {
            til_email.error = ""
            til_password.error = ""
            Toast.makeText(this@SheenValidatorAnnotationActivity, "Your form is valid, good job!", Toast.LENGTH_SHORT)
                .show()
        }
        ValidationBinder.bindValidator(sheenValidator, this)
        btn_login.setOnClickListener { sheenValidator.validate() }

 }
