하지만 세로로 1개씩만 나오네요,

어느 부분이 잘못된걸까요 ㅠ_ㅠ;;

 class ImageAdapter extends BaseAdapter {
 private Context mContext;
 
//테스트용으로 같은 이미지만 배열에 3개 가져왔습니다.
 int[] picture = { R.drawable.back_frame, R.drawable.back_frame, R.drawable.back_frame};
 
 public ImageAdapter(Context c) {
  mContext = c;
 }
 
 public int getCount() {
  return 10;
 }
 
 public Object getItem(int position) {
  return picture[position % 3];
 }
 
 public long getItemId(int position) {
  return position;
 }
 
 public View getView (int position, View convertView, ViewGroup parent) {
  ImageView imageView;
 if (convertView == null) {
   imageView = new ImageView(mContext);
   imageView.setAdjustViewBounds(false);
  } else {
   imageView = (ImageView) convertView;
  }
  imageView.setImageResource(picture[position % 3]);
  return imageView;
 }
