kotlin中的过载分辨率模糊错误

Question

我如何解决这个重载错误,我有重载分辨率歧义错误,我在我的项目中同步并清理它并重建它但它让我吼了一下错误,我在kotlin添加主要活动代码2布局活动这里是一张照片错误

这是一个主要的活动.kt

class MainActivity : AppCompatActivity() {

var adapter:FoodAdapter?=null
var listOfFoods =ArrayList<Food>()
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    // load foods


 listOfFoods.add(Food("Coffee","   Coffee preparation is",R.drawable.a))
   .....

    gvListFood.adapter =adapter

}


class  FoodAdapter:BaseAdapter {
    var listOfFood= ArrayList<Food>()
    var context:Context?=null
    constructor(context:Context,listOfFood:ArrayList<Food>):super(){
        this.context=context
        this.listOfFood=listOfFood
    }
    override fun getView(p0: Int, p1: View?, p2: ViewGroup?): View {
        val food = this.listOfFood[p0]
        var inflator = context!!.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
        var foodView= inflator.inflate(R.layout.food_ticket,null)
        foodView.ivFoodImage.setImageResource(food.image!!)
        foodView.ivFoodImage.setOnClickListener {

            val intent = Intent(context,FoodDetails::class.java)
            intent.putExtra("name",food.name!!)
            intent.putExtra("des",food.des!!)
            intent.putExtra("image",food.image!!)
            context!!.startActivity(intent)
        }
        foodView.tvName.text = food.name!!
        return  foodView

    }

    override fun getItem(p0: Int): Any {
        return listOfFood[p0]
    }

    override fun getItemId(p0: Int): Long {
       return p0.toLong()
    }

    override fun getCount(): Int {

        return listOfFood.size
    }

    }
 }

这是一个布局xml

Answer 1

您ivFoodImage在两个布局中定义.而你正在导入他们的定义......

import kotlinx.android.synthetic.main.activity_food_details.view.*
import kotlinx.android.synthetic.main.food_ticket.view.*

考虑更改其中一个布局中的名称,或者在定义中明确更改名称foodView,或者activity_food_details如果未使用则删除导入.

编辑

澄清可能的解决方案......

1. "更改名称" - 在您的某个布局中,将ivFoodImage更改为其他类似的内容ivFoodImage_Details.
2. "删除未使用的导入" - 自我解释和良好做法.
3. "显式" - 删除你想要显式的那个的导入,然后执行OP正在做的事情,即,在这种情况下var foodView = inflator.inflate(R.layout.food_ticket,null)显式加载food_ticket.

在多个布局中使用相同名称的概念也不错(从接口和注入的角度来看).但这kotlinx.android.synthetic是一种语法糖果,使事情变得不那么冗长.它妨碍了这里的目标.

这是另一种选择.如果你想让一个布局实现一种"接口",考虑用自己的Kotlin类包装每个布局,让类实现接口.如果你有很多这样的布局,这可能会变得乏味,所以"选择你的毒药",这只是另一个想法.

最后,请参阅@Daniel Wilson的回答.它避免了编译器错误,并使您指定ivFoodImage要使用的命名空间.

Answer 2

引用此答案,您可以专门导入所需的ID,并使用Kotlin的as关键字为其命名

package XXX

import kotlinx.android.synthetic.main.num_info_inet_plus_pack.view.circle as inetViewCircle
import kotlinx.android.synthetic.main.num_info_pack.view as circle
//...
val inetView = activity.layoutInflater.inflate(R.layout.num_info_pack, parent, false)
inetViewCircle.setBackgroundResource(background)
