Android GridView 끌어서 놓기 ImageView

Question

안드로이드 용 라이브러리 "DraggableGridView"를 사용 중입니다. 일부 이미지를 수정하여 이미지를 만들려고하고 있지만 앱이 계속 충돌을 일으키지 만 여기에 코드를 남겨 두었습니다. 사람이 나를 도울 수있다 : S

public class HomeFragment extends Fragment { 

    private ImageView one; 
    private ImageView two; 
    private DraggableGridView dgv; 


    public HomeFragment(){} 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 


     View rootView = inflater.inflate(R.layout.fragment_home, container, false); 

     dgv = (DraggableGridView)rootView.findViewById(R.id.dgv); 

     one =(ImageView)rootView.findViewById(R.id.moodleLogo); 
     two =(ImageView)rootView.findViewById(R.id.aulawebLogo); 

     return rootView; 
    } 

    @Override 
    public void onActivityCreated(Bundle savedInstanceState) { 
     super.onActivityCreated(savedInstanceState); 
     setHasOptionsMenu(true); 

     setListeners(); 

    } 

    private void setListeners() { 


     dgv.setOnItemClickListener(new OnItemClickListener() { 

      public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3){ 

       String url = (String)dgv.getChildAt(arg2).getTag(); 
       Intent i = new Intent(Intent.ACTION_VIEW); 
       i.setData(Uri.parse(url)); 
       startActivity(i); 
      } 
     }); 

    }

덕분에

Answer 1

는 사용하지 마십시오

String url = (String)dgv.getChildAt(arg2).getTag(); 

getChildAt 메서드는 위치 (arg2)와 아무 관련이없는 int를 사용합니다. 대신 어댑터를 쿼리하여 URL을 찾으십시오. 어댑터를 가정

는 String의 포함

String url = arg0.getAdapter().getItem(arg2);
