android : getView에서 오류가 발생했습니다.

Question

ThAdapter 클래스에 오류가 하나 있습니다. imageView에 이미지를 표시하고 textView에 이미지 이름을 표시하려고하지만 오류가 표시됩니다. 오류가 getView()에 있음을 알고 있지만 변경 방법을 알지 못합니다. 누군가가 나를 도울 수 있습니까 ??

public class Th extends BaseAdapter { 

// Context required for performing queries 
private final Context mContext; 

// Cursor for thumbnails 
private final Cursor cursor; 
private final int imgId; 
private final int imgData; 
private final int count; 

public Th(Context c) { 
    this.mContext = c; 

    // Get list of all images, sorted by last taken first 
    final String[] projection = { 
      MediaStore.Images.Media._ID, 
      MediaStore.Images.Media.DATA 
    }; 
    cursor = mContext.getContentResolver().query(
      MediaStore.Images.Media.EXTERNAL_CONTENT_URI, 
      projection, 
      null, 
      null, 
      MediaStore.Images.Media.DATE_TAKEN + " DESC" 
    ); 

    // Set constants (column indices and image count) 
    imgId = cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID); 
    imgData = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); 
    count = cursor.getCount(); 
    Log.d("ThumbnailAdapter", count + " images found"); 
} 

@Override 
public int getCount() { 
    return count; 
} 

@Override 
public Object getItem(int position) { 
    return position; 
} 

@Override 
public long getItemId(int position) { 
    return position; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    ImageView imageView; 
    TextView textView; 
    if (convertView == null) { // if it's not recycled, initialize some attributes 
     imageView = new ImageView(mContext); 
     textView = new TextView(mContext); 

    } else { 
     imageView = (ImageView) convertView; 
     textView = (TextView) convertView; 
    } 

    // Move cursor to image position, fetch id, and generate/view thumbnail 
    cursor.moveToPosition(position); 
    final Bitmap thumbnail = MediaStore.Images.Thumbnails.getThumbnail(
      mContext.getContentResolver(), 
      cursor.getInt(imgId), 
      MediaStore.Images.Thumbnails.MICRO_KIND, 
      null 
    ); 

    imageView.setImageBitmap(thumbnail); 
    textView.setText(cursor.getString(imgData)); 


    return imageView; 
} 

/** 
* Get the image path from the given position 
* @param position 
* @return 
*/ 
public String getImagePath(int position) { 
    cursor.moveToPosition(position); 
    return cursor.getString(imgData); 
}

getView는 이미지보기 만 리턴합니다. 따라서 텍스트 뷰는 사용되지 않습니다.
