Xamarin이 Android 인플레이 트보기와 동기화되지 않은 리소스 ID를 생성했습니다.

Question

ListView에 표시 할보기를 부 풀리는 ListView 어댑터가 있습니다. 내가 같이 findViewById (Resource.Id.ItemId)를 사용하여보기에서 항목의 일부를 얻을 때 디버거가 발생하고 오류가 말하는 :

"System.InvalidCastException : 'Android.Widget 유형의 인스턴스를 변환 할 수 없습니다. TableRow '를 입력하여'Android.Widget.TextView ' "을 입력하십시오.

내가 사용하는 리소스 ID가 TextView에 매핑되어야한다는 것을 알고 있습니다.

또한 일부 항목에는 값을 가져 오지 못하므로 항상 기본값을 표시하는 다른 문제가 있습니다. 코드 여기

누군가가 자동으로 생성 된 이유를 알고 있나요을 리소스가 Android의 확장 된보기와 동기화되지 않습니까?

Answer 1

확실치 않지만 잘못된보기를보고있을 수 있습니다.

var Row = convertView ?? Context.LayoutInflater.Inflate(Resource.Layout.TripListViewRow, null);

실제로, 당신에게 TableLayout을 포기하지 않을 중 하나 TableRow의의입니다. 실제 TableRow의를 얻으려면 다음 actualRow1 및 actualRow2에 등 당신의 TextView의, 찾아

TableRow actualRow1 = Row.FindViewById<TableRow>(Resource.Id.tripViewTableRow1); 
TableRow actualRow2 = Row.FindViewById<TableRow>(Resource.Id.tripViewTableRow2); 

을 할 필요가 있습니다.
