Fehler im Datenbindungs-Validator von Ilhasoft + Kotlin

Question

Ich versuche, die Android-Bibliothek "Data Binding Validator by Ilhasoft" mit Kotlin zu verwenden, aber ich bekomme diesen Fehler: Nicht aufgelöste Referenz: validate.

, dass meine Wurzel build.gradle ist:

buildscript { 
    ext.kotlin_version = '1.1.60' 
    ext.android_plugin_version = '3.0.0' 
    ext.data_binding_validator_verson = '1.0.0' 
    repositories { 
     jcenter() 
     google() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:3.0.0' 
     classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" 

    } 
} 

allprojects { 
    repositories { 
     jcenter() 
     maven { url 'https://jitpack.io' } 
    } 
} 

task clean(type: Delete) { 
    delete rootProject.buildDir 
} 

Das ist meine APP build.gradle ist:

Und zum Schluss, dass:

    }

    dataBinding { 
     enabled = true 
    } 
} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { 
     exclude group: 'com.android.support', module: 'support-annotations'

} 
repositories { 
    mavenCentral() 
    google() 
} 

kapt { 
    generateStubs = true 
} 

Das ist mein fragment_cadastrar_user ist ist mein onCreateView in meinem Fragment:

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? { 

    val view = inflater.inflate(R.layout.fragment_cadastrar_user, null) 

    //Binding Api 
    val binding: FragmentCadastrarUserBinding = DataBindingUtil.setContentView(activity as Activity, R.layout.fragment_cadastrar_user) 
    val validator = Validator(binding); 

    binding.validate.setOnClickListener(View.OnClickListener { 
     if (validator.validate()) { 
      registerUser() 
     } 
    }) 

    binding.setUser(user); 

    view.user_phone.addTextChangedListener(PhoneNumberFormattingTextWatcher()) 

    return view 
} 

And to complement this is a picture with my error.

Könnte mir jemand dabei helfen. Danke!

Answer 1

validate ist die ID der Schaltfläche im Beispiel der Bibliothek.

Sie sollten die ID der Schaltfläche verwenden, die Sie validieren möchten. Ich denke es ist new_user_button.

Also mit Bindung sollte es wie newUserButton sein.

So Ihr volles Beispiel wird wie:

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? { 

    val view = inflater.inflate(R.layout.fragment_cadastrar_user, null) 

    //Binding Api 
    val binding: FragmentCadastrarUserBinding = DataBindingUtil.setContentView(activity as Activity, R.layout.fragment_cadastrar_user) 
    val validator = Validator(binding); 

    // CHANGE IN BELOW LINE 
    binding.newUserButton.setOnClickListener(View.OnClickListener { 
     if (validator.validate()) { 
      registerUser() 
     } 
    }) 

    binding.setUser(user); 

    view.user_phone.addTextChangedListener(PhoneNumberFormattingTextWatcher()) 

    return view 
}
