GridView 내부에서 ImageView를 동적으로 바꾸는 방법 (안드로이드)?

Question

그래서 간단한 보드 게임을 만들어야합니다. 그것은 조각 내의 Gridview (10x10)를 기반으로합니다. 활동은 또한 컨트롤이있는 다른 조각을 표시합니다 (왼쪽 아래로). 컨트롤 조각의 버튼을 눌렀을 때 GridView 내부로 이미지를 이동해야합니다. 지금까지 GridView를 채울 수 있었지만 이미지를 내부로 이동하는 방법을 알 수 없습니다.

이 그리드 조각

 public class Grid extends Fragment{ 
     GridView gridView; 
     private View rootView; 
     public PhotoImageAdapter mAdapter; 
     Integer[] image = { 
       R.drawable.pucman, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, 
       R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, 
       R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, 
       R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, 
       R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, 
       R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, 
       R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, 
       R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, 
       R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, 
       R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, R.drawable.ground, 
     }; 


     @Override 


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

      rootView = inflater.inflate(R.layout.fragment_grid, container, false); 
      gridView = rootView.findViewById(R.id.GridView); 
      gridView.setAdapter(new PhotoImageAdapter(this.getActivity(), image)); 
      return rootView; 


     } 


    public void goRight()// this function is called by the control fragment. 
    { 
    // here is my not so fructuous attempt to replace the image in the 
    //second cell with the image of my character 

    image[1]=R.drawable.pucman; 
    image[0]=R.drawable.ground; 

    } 

에게 인이 내 어댑터입니다 :

public class PhotoImageAdapter extends BaseAdapter { 
    private Context mContext; 
    public Integer[] mThumbIds; 



    public PhotoImageAdapter(Context c, Integer[] image) { 
     mContext = c; 
     mThumbIds = image; 


    } 

    public int getCount() { 
     return mThumbIds.length; 
    } 

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

    public long getItemId(int position) { 
     return 0; 
    } 

    public View getView(int position, View convertView, ViewGroup parent) { 
     ImageView imageView; 
     if (convertView == null) { // if it's not recycled, initialize some attributes 
      imageView = new ImageView(mContext); 
      imageView.setLayoutParams(new GridView.LayoutParams(80, 80)); 
      imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); 
      imageView.setPadding(8, 8, 8, 8); 
     } else { 
      imageView = (ImageView) convertView; 
     } 


     imageView.setImageResource(mThumbIds[position]); 
     return imageView; 
    } 

} 

어떤 도움이 크게 감사합니다! 주셔서 감사합니다 :)

Answer 1

나는 마침내 그것을 알아 냈어! 난 그냥 조각을 대체하고 goRight()를 호출 할 때 트랜잭션을 커밋해야했습니다. 그것이 누군가를 도울 수 있기를 바랍니다.

Answer 2

난 당신이 각 이동에 어댑터를 업데이트 할 필요가 있다고 생각 업데이트 된 이미지 배열로 이미지의 배열을 변경 한 후이 줄을 추가하려고 :

gridView.setAdapter(new PhotoImageAdapter(this.getActivity(), image));
