Could you please explain in more detail which part of the task presents difficulties for you? Are you building an Android application?

What do you mean by “I don’t get any resource”? You can use any Java libraries in Kotlin, including Volley.

this is my adapter.kt

class testAdapter( val context: Context, var rowItems: ArrayList) : BaseAdapter() {

```
override fun getCount(): Int {
    return rowItems.size
}

override fun getItem(i: Int): ArtGallery {
    return rowItems[i]
}

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

constructor(rowItems: ArrayList<ArtGallery>) : this(context , rowItems) {
    this.rowItems = rowItems;
}

override fun getView(i: Int, convertView: View?, parent: ViewGroup): View {
    var convertView = convertView
    if (convertView == null) {
       convertView= LayoutInflater.from(parent.getContext()).inflate(R.layout.listview_row, parent, false);
    }

```

}

and here where i’m set adapter to listview…like this…  
{  
val restaurant\_list: ListView = findViewById(R.id.restaurant\_lv) as ListView

```
    rowItems = ArrayList()
    val list_adapter = testAdapter(applicationContext,rowItems)
    restaurant_list.adapter = list_adapter

```

}

using volley

{  
val repoName = jsonObject.getString(“Restaturant\_name”)  
val fullName = jsonObject.getString(“Category”)  
val img\_url = jsonObject.getString(“img”)

```
                    val items = ArtGallery(repoName, fullName, img_url)
                    items.artist = repoName
                    items.title = fullName
                    items.main_image = img_url

                    rowItems.add(items)

```

}  
but i didn’t get data i adapter nor in arraylist…where i’m doing mistake…?

Hello,

Download source code from ([Listview in Kotlin Android](http://deepshikhapuri.blogspot.in/2017/09/listview-in-kotlin-android.html)).

**Model.kt:**

> public class Model\_flower{  
> var str\_name:String =“”  
> var str\_des:String =“”  
> var int\_image:Int=0
> 
> ```
> constructor(str_name:String,int_image:Int,str_des:String){
> this.int_image=int_image
> this.str_name=str_name
> this.str_des=str_des
> 
> }
> 
> ```

**CustomAdapter.kt:**

> package com.deepshikha.listviewinkotlin
> 
> import android.content.Context  
> import android.view.LayoutInflater  
> import android.view.View  
> import android.view.ViewGroup

> import android.widget.ImageView  
> import android.widget.TextView
> 
> class CustomAdapter(context: Context,al\_flower:ArrayList\<Model\_flower\>) : BaseAdapter(){

> private val mInflator: LayoutInflater
> private val al_flower:ArrayList<Model_flower>
> 
> init {

> this.al_flower=al_flower
> }
> 
> override fun getCount(): Int {

> 
> override fun getItem(position: Int): Any {

> 
> override fun getItemId(position: Int): Long {

> vh = view.tag as ListRowHolder
> }
>

> vh.iv_image.setImageResource(al_flower.get(position).int_image)
> return view
> }
> 
> ```
> 
> }
> 
> private class ListRowHolder(row: View?) {
