입니다

내 문제는이 CustomAdapter를 호출 할 때마다 하나의 목록 항목 만 있으면 완벽하게 작동하지만 여러 목록 항목이있을 때마다 어댑터가 이상하게 작동하기 시작한다는 것입니다. 예를 들어, 두 개의 항목이있을 때마다 첫 번째 항목에 대해 "자세히보기"버튼을 누르면 두 번째 항목에 대해 트리거됩니다. 로그에서 작업중인 데이터가 첫 번째 항목임을 나타냅니다.

두 개 이상의 항목이있는 경우 위의 패턴이 관찰됩니다. 즉, 주어진 항목의 '자세히보기'버튼을 클릭 할 때마다 목록보기의 다음 항목을 트리거합니다. 때로는 이미지가로드되거나 "자세히 알아보기"버튼이 응답하지 않은 경우에도 "로드 중"에 멈추는 경우가 있습니다. 나는 지난 2 일 동안 내 머리를 치며 버그를 찾고있다. 너희들이 나를 도울 수 있기를 바랍니다. 사전에 감사합니다.

추 신 : "Load More"버튼이 작동하지 않습니다. 실례합니다.

모델 내에서 각 항목의 상태를 저장해야합니다 (자세히 읽었거나 읽지 않은 경우). 또한'readMoreFunction' 메쏘드는 오래된 데이터를 사용하고 있습니다. 항상 getView의 마지막 반복의 값을가집니다. –

현재 데이터를 사용하고 getView에서 부실 데이터를 방지하려면 어떻게해야합니까? – THGRoy

내부 GEvent 클래스는 getView 내부

class GEvent { 
    private boolean readMoreClicked; 

    public boolean isReadMoreClicked(){ 
     return readMoreClicked; 
    } 

    public void setReadMoreClicked(boolean readMoreClicked){ 
     this.readMoreClicked = readMoreClicked; 
    } 
}

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

    .... 

    if(gEvent.isReadMoreClicked()) { 
     Log.i("CA","Entered More Less Function"); 
     ... 
    } else { 
     Log.i("CA","Entered Less More Function"); 
     ... 
    } 

    readMoreButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      if(hasLoaded) { 
       Log.i("CA","Entered hasLoaded Function"); 

       // user has clicked Read More. Save the state 
       gEvent.setReadMoreClicked(!gEvent.isReadMoreClicked()); 
       notifyDataSetChanged(); 

      } else { 
       Toast.makeText(mContext,"Loading....",Toast.LENGTH_LONG).show(); 
      } 
     } 
    }); 

    ... 
}

그것은 약간의 편집이 필요할 수 있습니다하는 boolean 필드를 만듭니다. 그러나 당신이 아이디어를 얻길 바랍니다. :)
