New page

*Create a List View to display your items
*In a separate layout file create an item view
*Create a new file with Kotlin Class, call it XXXAdapter or whatever. eg
<pre>
class CategoryAdapter(context:Context, categories:List<Category>): BaseAdapter() {}
</pre>
You will have to override getView, getItem, getItemId, getCount
<pre>
class CategoryAdapter(context:Context, categories:List<Category>): BaseAdapter() {

val context = context
val categories = categories

override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View {
val categoryView :View

categoryView = LayoutInflater.from(context).inflate(R.layout.category_list_item,null)

val resourceID = context.resources.getIdentifier(categories[position].image,"drawable",context.packageName)
categoryView.categoryImage.setImageResource(resourceID)
categoryView.categoryText.text = categories[position].title
return categoryView
}

override fun getItem(position: Int): Any {
return categories[position]
}

override fun getItemId(position: Int): Long {
return 0
}

override fun getCount(): Int {
return categories.count()
}

}
</pre>
