Kotlin gridView is not displayed in fragment

Question

i would like to use a grind view in a fragment but i couldn't find how to do it. so i tried to adapte the way i did it in an activity but even if i don't get a crash, the grid is not displayed. Here is my code : Fragment

class DashboardFragment : Fragment() {

private var _binding: FragmentDashboardBinding? = null

private val binding get() = _binding!!

lateinit var courseGRV: GridView
lateinit var courseList: List<GridViewModal>

override fun onCreateView(
    inflater: LayoutInflater,
    container: ViewGroup?,
    savedInstanceState: Bundle?
): View {
    val dashboardViewModel =
        ViewModelProvider(this).get(DashboardViewModel::class.java)

    _binding = FragmentDashboardBinding.inflate(inflater, container, false)
    val root: View = binding.root

    //courseGRV = findViewById(R.id.idGRV)
    val view: View = inflater.inflate(R.layout.fragment_dashboard, container, false)
    courseGRV = view!!.findViewById(R.id.idGRV) as GridView
    courseList = ArrayList<GridViewModal>()

    courseList = courseList + GridViewModal("Art", R.drawable.art)
    courseList = courseList + GridViewModal("Culture", R.drawable.culture)
    courseList = courseList + GridViewModal("Hobbies", R.drawable.hobbies)

    println(courseList.size) //this work and give me 3
    val courseAdapter = GridRVAdapter(courseList = courseList, this.requireContext()

    courseGRV.adapter = courseAdapter
    //courseGRV.get(0) //this give me java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
   
    courseGRV.onItemClickListener = AdapterView.OnItemClickListener { _, _, position, _ ->
 
        Toast.makeText(
            this.requireContext(), courseList[position].courseName + " selected",
            Toast.LENGTH_SHORT
        ).show()
    }

    return root
}

override fun onDestroyView() {
    super.onDestroyView()
    _binding = null
}

}

adapter

    internal class GridRVAdapter(
    private val courseList: List<GridViewModal>,
    private val context: Context) :BaseAdapter() {

    private var layoutInflater: LayoutInflater? = null
    private lateinit var courseTV: TextView
    private lateinit var courseIV: ImageView

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

    // below function is use to return the item of grid view.
    override fun getItem(position: Int): Any? {
        return null
    }

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

    override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View? {
        var convertView = convertView
     
        println("getview")// never called
        if (layoutInflater == null) {
            layoutInflater =
                context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
        }
     
        if (convertView == null) {
            convertView = layoutInflater!!.inflate(R.layout.gridview_item, null)
        }
        courseIV = convertView!!.findViewById(R.id.idIVCourse)
        courseTV = convertView!!.findViewById(R.id.idTVCourse)

        courseIV.setImageResource(courseList.get(position).courseImg)
        
        
        courseTV.setText(courseList.get(position).courseName)
        
        return convertView
    }
}

data class GridViewModal(

    val courseName: String,
    val courseImg: Int
)

So i don't get why my grid is not displayed, with some print i tried, i saw that the adapter is full before i add it to my gridView, but the getView of the adapter is never called. Also if i want to access to item inside my gridView i get an index out of bound so i assume that it's not fully initialize or populate.

If someone could help me with my problem i would really appreciate.
