Ошибка сборки Gradle в Android Studio for Dependent Spinner

0 голосов
/ 05 мая 2020

Я писал код для своего мобильного приложения.

Мое приложение написано на Kotlin вместо Java, но если было сказано, то я тоже буду декомпилировать Java.

Мой главный мотив в настоящее время - добавить в мое приложение параметр просмотра зависимого списка с помощью параметра Spinner и привязки данных. Итак, я создал несколько счетчиков в моем activity_order. xml.

Это мой activity_order. xml

</androidx.constraintlayout.widget.ConstraintLayout>

В этом упражнении я хотел сначала создать зависимый список с идентификатором прядильщика spinner_district , а все остальные зависят от верхнего прядильщика.

Поэтому я сначала добавил следующий код в свой файл Gradle 

 viewBinding
             {
                 enabled=true
             }

, а затем начал создавать команду привязки для списка в моем Kotlin файле следующим образом: 

 val binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)

        val arrayList_District= arrayListOf<String>("Hapur","Meerut","Noida")
        val arrayAdapter_District=ArrayAdapter(applicationContext,R.layout.list_district,arrayList_District)
        binding.spParent.adapter=arrayAdapter_District

Это мой полный kotlin файл для activity_order. xml с именем Order.kt 

package com.example.e_dukan

import android.app.Activity
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.view.LayoutInflater
import android.view.View
import android.widget.AdapterView
import android.widget.ArrayAdapter
import android.widget.Spinner
import com.example.e_dukan.databinding.ActivityMainBinding

class Order : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_order)

////////////////////////////////////////////////////////////////////////////////////////////////////

        val binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)

        val arrayList_District= arrayListOf<String>("Hapur","Meerut","Noida")
        val arrayAdapter_District=ArrayAdapter(applicationContext,R.layout.list_district,arrayList_District)
        binding.spParent.adapter=arrayAdapter_District

////////////////////////////////////////////////////////////////////////////////////////////////////

        val spinner: Spinner = findViewById(R.id.spinner_district)
// Create an ArrayAdapter using the string array and a default spinner layout
        ArrayAdapter.createFromResource(
            this,
            R.array.spinner_district,
            android.R.layout.simple_spinner_item
        ).also { adapter ->
            // Specify the layout to use when the list of choices appears
            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item)
            // Apply the adapter to the spinner
            spinner.adapter = adapter
        }

////////////////////////////////////////////////////////////////////////////////////////////////////

    }
}
/*
class Order : Activity(), AdapterView.OnItemSelectedListener {
    override fun onItemSelected(parent: AdapterView<*>, view: View, pos: Int, id: Long) {
        // An item was selected. You can retrieve the selected item using
        // parent.getItemAtPosition(pos)
        val spinner: Spinner = findViewById(R.id.spinner_district)
        spinner.onItemSelectedListener = this
    }

    override fun onNothingSelected(parent: AdapterView<*>) {
        // Another interface callback
    }
}
*/

Но когда я собираю градиент, он показывает следующую ошибку:

Созданный класс для использования в привязке данных будет иметь то же имя, что и имя макета

: Неразрешенная ссылка: ActivityMainBinding

Поэтому вам следует использовать ActivityOrderBinding вместо ActivityMainBinding

Другое, замените 

setContentView(R.layout.activity_order)
  val binding = ActivityMainBinding.inflate(layoutInflater)
  setContentView(binding.root)

на 

val binding : ActivityOrderBinding =
DataBindingUtil.setContentView(this, R.layout.activity_order)

И чтобы получить представление используйте binding.root

Чтобы узнать больше о привязке данных, взгляните на это code lab tuto
