BaseAdapter의 이미지 위치가 맞지 않습니다.

Question

5 개 섹션 (각 섹션은 목록의 항목 임)이있는 PullToRefresh ListView가 있으며 각 섹션에는 여러 개의 사진이 있습니다. 5 개의 섹션을 섹션 사진으로 채우는 BaseAdapter 클래스가 있습니다. 문제는 목록보기를 처음로드 할 때 사진이 올바르게 표시되지 않지만 스크롤 할 때 사진이 올바른 위치에 나타날 때입니다. 사진을로드 할 때 BitmapFun 코드를 사용합니다.

제가 가지고

private ArrayList<Pair<Integer, ArrayList<String>>> section_photos_url; 

제 값은 부이고, 두 번째는 각 섹션의 사진 배열이다.

의 getView 방법 :

public View getView(int position, View convertView, ViewGroup container) { 

    if (position < 5) { 

     ItemViewHolder viewHolder;

어떤 제안이 이미지를 제대로 보여? 그것들은 이미지들입니다. 모든 사진이 보라색 꽃 사진이어야하고 노란색이 아니기 때문에 첫 번째 사진은 잘못된 이미지입니다. 두 번째 것은 정확합니다. 이미지는

Answer 1

첫 번째 섹션의 일부, 어떤 view_array 것은 당신이 사용하는 경우 그 목록의 위치에 저장 볼 수 있습니다. 그렇다면 그 잘못입니다. 이 목록은보기를 다시 사용하기 위해 구현됩니다.

둘째, 목록보기에 다른 레이아웃을 사용하기 위해 getItemViewType() 및 getViewTypeCount()를 사용합니다.

아래

참조 예를 들어,

public class Adapter extends BaseAdapter { 

    private static final int SECTION1 = 0; 
    private static final int SECTION2 = 1; 
    private static final int SECTION3 = 2; 
    private static final int SECTION4 = 3; 
    private static final int SECTION5 = 4; 

    ... 

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

     View view; 

     int type = getItemViewType(position); 

     if (convertView == null) 
     { 
      switch (type) { 
      case SECTION1: 
       view = inflater.inflate(layout_id1, parent, false); 
       break; 
      case SECTION2: 
       view = inflater.inflate(layout_id2, parent, false); 
       break; 
      case SECTION3: 
       view = inflater.inflate(layout_id3, parent, false); 
       break; 
      case SECTION4: 
       view = inflater.inflate(layout_id4, parent, false); 
       break; 
      case SECTION5: 
       view = inflater.inflate(layout_id5, parent, false); 
       break; 
      } 
     } 
     else 
     { 
      // Based on value of getItemViewType the ListView will pass the 
      // corresponding layout which was inflated before by getView so no need to inflate again 
      view = convertView; 
     } 

     ... 

     return view; 
    } 

    // getItemViewType should return value from 0 to 4 since the count is 5 
    // See doc for more info 
    @Override 
    public int getItemViewType(int position) { 
     // return the section type which should be in range 0 to 4 
    } 

    @Override 
    public int getViewTypeCount() { 
     return 5; 
    } 
}
