클래스 캐스트 예외 ... 확장 가능한 목록보기에서 텍스트보기

Question

클래스 중 하나의 클래스 59에 classcastexception이 생깁니다. 로그에 확장 가능한 목록보기를 텍스트보기로 캐스팅하려고한다는 메시지가 표시됩니다.

다음

@Override 
    public View getView(int position, View convertView, ViewGroup parent) { 

     if (convertView == null) { 

      LayoutInflater inflater = (LayoutInflater) mContext 
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      convertView = inflater.inflate(R.layout.sms_status_list_item, null); 

      viewHolder = new ViewHolder(); 

      viewHolder.textView = (TextView) convertView.findViewById(R.id.tv_sms_status); 
      viewHolder.imageView = (ImageView) convertView.findViewById(R.id.iv_sms_status_icon); 

      convertView.setTag(viewHolder); 
     } else { 

      viewHolder = (ViewHolder) convertView.getTag(); 
     } 

     viewHolder.textView.setText(getStatusText()); // this is line 59 
     viewHolder.imageView.setImageResource(getImage()); 

     return convertView; 
    } 

    public class ViewHolder { 

     TextView textView; 
     ImageView imageView; 
    } 

이 sms_status_list_item.xml

입니다

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/linearLayout1" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:gravity="center_vertical" > 

    <TextView 
     android:id="@+id/tv_sms_status" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_centerVertical="true" 
     android:paddingLeft="@dimen/activity_horizontal_margin" 
     android:text="Status" 
     android:textAppearance="?android:attr/textAppearanceMedium" /> 

    <ImageView 
     android:id="@+id/iv_sms_status_icon" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:paddingRight="@dimen/activity_horizontal_margin" 
     android:layout_centerVertical="true" 
     android:clickable="false" 
     android:layout_alignParentTop="true" 
     android:layout_alignParentRight="true" 
     android:layout_alignParentEnd="true" /> 

</RelativeLayout>

때때로 컴파일러가 멈추고 xml 파일에 대한 변경 사항을 볼 수 없기 때문에 XML에서 뷰 (textview 및 imageview)를 바꿀 수 있습니다.
