Xamarin Adapter FindViewById returns null
Not sure what I'm doing wrong here but FindViewById always returns null for my custom row view:
public override View GetView(int position, View convertView, ViewGroup parent) {
var view = convertView;
var item = items[position];
if(view == null)
view = context.LayoutInflater.Inflate(Resource.Layout.listview_row, null);
var nameTextView = view.FindViewById<TextView>(Resource.Id.nameTextView);
var priceTextView = view.FindViewById<TextView>(Resource.Id.priceTextView);
nameTextView.Text = item.Name;
priceTextView.Text = (item.Price ?? 0M).ToString("#.00");
return view;
}
This is the view code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView id="@+id/nameTextView"
android:layout_height="wrap_content"
android:layout_width="0dp"
android:layout_weight="0.8"
android:layout_margin="5dp" />
<TextView id="@+id/priceTextView"
android:layout_height="wrap_content"
android:layout_width="0dp"
android:layout_weight="0.2"
android:layout_margin="5dp" />
</LinearLayout>
The view inflates correctly but for some reason both TextViews are always null after the call to FindViewById.
I have tried cleaning and rebuilding the project but that did not work. Not sure why this is not working.
Thank you for any pointers.

You are providing an id with the wrong way hence it is not getting registered in Resource designer
Try this :
android:id="@+id/nameTextView"
android:id="@+id/priceTextView"
