GlideAppでListViewに画像を表示について教えてください。

class ListAdapter(context: Context, var dogList:ArrayList<RecordDB>) :ArrayAdapter<RecordDB>(context,0,dogList){

    private val layoutInflater=context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater

    lateinit var DBDB:RecordDB

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

        val rec=dogList[position]
        var view=convertView

        if (null==view){
            view=layoutInflater.inflate(R.layout.list_item,parent,false)
        }

        val Imageviewlist=view?.findViewById<ImageView>(R.id.image_list)
        //GlideにてFirebaseStoreから画像のURLを取得しImageViewに挿入する
        DBDB= RecordDB(ImageDataUrl = String())
        GlideApp.with(context)
            .load(DBDB.ImageDataUrl!![position])
            .into((Imageviewlist)view)

             val name=view?.findViewById<TextView>(R.id.text_Name)
        name?.text=rec.Name

        val time=view?.findViewById<TextView>(R.id.text_Time)
        time?.text=rec.Time.toString()

        val caption=view?.findViewById<TextView>(R.id.text_Caption)
        caption?.text=rec.Caption

        val image_name=view?.findViewById<TextView>(R.id.textView3)
        image_name?.text=rec.ImageName


        return view!!
    }

data class RecordDB(val uid:String?="",
                    val Time:String?="",
                    val Name:String?="",
                    val Caption:String?="",
                    val ImagePhoto:Int=0,
                    val ImageName:String?="",
                    val ImageDataUrl:String?="")

This view is not constrained vertically: at runtime it will jump to the top unless you add a vertical constraint
