How to use

@Validations
class TestActivity : Activity() {

    @NotEmpty(R.id.username, messageResId = R.string.err_username_validation)
    var editTextUsername: TextInputEditText? = null

    @Password(R.id.password, messageResId = R.string.err_password_validation)
    var editTextPassword: TextInputEditText? = null

    @ConfirmPassword(R.id.confirm_password, messageResId = R.string.err_confirm_password_validation)
    var editTextConfirmPassword: TextInputEditText? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_test)
        
        // Don't forget to bind your activity, fragment or view
        Validator.bind(this)
    }

    @ValidateOnClick(R.id.buttonActivityMainSubmit)
    fun onSubmitClicked() {
        Toast.makeText(this, "Validation succeeded", Toast.LENGTH_SHORT).show()
    }
}

Auto validate while typing

@Validations
class TestActivity : Activity() {

    @AutoValidate
    @NotEmpty(R.id.username, messageResId = R.string.err_username_validation)
    var editTextUsername: TextInputEditText? = null
    
    ....
}

Library Projects

For library projects add Butterknife's gradle plugin to your buildscript.

buildscript {
  repositories {
    mavenCentral()
   }
  dependencies {
    classpath 'com.jakewharton:butterknife-gradle-plugin:10.1.0'
  }
}

and then apply it in your module:

apply plugin: 'com.android.library'
apply plugin: 'com.jakewharton.butterknife'

Now make sure you use R2 instead of R inside all WinValidation annotations.

@Validations
class TestActivity : Activity() {

    @AutoValidate
    @NotEmpty(R2.id.username, messageResId = R2.string.err_username_validation)
    var editTextUsername: TextInputEditText? = null
    
    ....
}
