Trying to add images to my recycler view, can't assign drawable-CodePudding

`package com.truuce.anotherrvtest
 
import android.media.Image
 
data class Item (
    val title:String,
    val image: Int    
        )            // I can change image type to Drawable to get .setImageDrawable to be accepted by IDE but then the "R.drawable.ashbringer" all need to be changed to something else`

`package com.truuce.anotherrvtest
 
object ItemList {
    val itemList = listOf<Item>(
        Item("Ashbringer", R.drawable.ashbringer),  
        Item("Citadel", R.drawable.ashbringer),        
        Item("Stonewall", R.drawable.ashbringer),    
        Item("Tainted Blade", R.drawable.ashbringer)
    )
}
 
// these are of type Int so they do not work when image is set to Drawable`

`package com.truuce.anotherrvtest
 
import android.view.ViewGroup
import androidx.recyclerview.widget.RecyclerView
import com.truuce.anotherrvtest.databinding.RecyclerItemBinding
 
class ItemAdapter:RecyclerView.Adapter<ItemAdapter.MainViewHolder>() {
 
    inner class MainViewHolder(val itemBinding: RecyclerItemBinding) :
        RecyclerView.ViewHolder(itemBinding.root) {
        fun bindItem(item: Item){
            itemBinding.itemNameTV.text = item.title
            itemBinding.image.setImageDrawable(item.image)   // what do I need here??
        }
    }

 
}`

I've tried changing the val image: Int to type drawable instead, but then I have to change the "R.drawable.ashbringer" to something else, but idk what.

I'm sure this is an easy fix for ya'll on here, but I'm stumped.

CodePudding user response：

Use setImageResource instead, it accepts an integer as the drawable resource id

Further more you can mark your image variable as @DrawableRes to identify it as an drawable resource, not a normal integer.

CodePudding user response：

Use ContextCompat to get the drawable first, then try setting it

I figured it out.. just needed to use .setImageResource(). This works with R.drawable.ashbringer

`package com.truuce.anotherrvtest
 
import android.view.ViewGroup
import androidx.recyclerview.widget.RecyclerView
import com.truuce.anotherrvtest.databinding.RecyclerItemBinding
 
class ItemAdapter:RecyclerView.Adapter<ItemAdapter.MainViewHolder>() {
 
    inner class MainViewHolder(val itemBinding: RecyclerItemBinding) :
        RecyclerView.ViewHolder(itemBinding.root) {
        fun bindItem(item: Item){
            itemBinding.itemNameTV.text = item.title
            itemBinding.image.setImageResource(item.image)  //here
        }
    }

 
}`
