我正在使用本教程制作gridview: https://developer.android.com/guide/topics/ui/layout/gridview.html

我已将mThumbIds从array更改为List<Integer>,并且我尝试使用通过Bundle从MainActivity传入dataGridFragment的数据初始化它,但它不起作用。如果我手动添加元素,它可以工作。我认为捆绑包来得太晚但不知道如何同步它。

public class GameFragment extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.sudoku_game_fragment,
                container, false);
        ImageAdapter adapter = new ImageAdapter(getActivity());
        List<Integer> array ;

        GridView gridview = (GridView) view.findViewById(R.id.gridview);
        gridview.setAdapter(adapter);
        if(getArguments() != null) {
             array =getArguments().getIntegerArrayList("values");
            adapter.mThumbIds.add(0, R.drawable.zero);
            }

        adapter.notifyDataSetChanged();
        gridview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View v,
                                    int position, long id) {
                Toast.makeText(getActivity(), "" + position,
                        Toast.LENGTH_SHORT).show();
            }
        });

        return view;
    }



public class ImageAdapter extends BaseAdapter {
    private Context mContext;

    public List<Integer> mThumbIds = new ArrayList<Integer>();
  //  public Integer[] mThumbIds;

    public ImageAdapter(Context c) {
        mContext = c;






    }

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

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

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

    // create a new ImageView for each item referenced by the Adapter
    public View getView(int position, View convertView, ViewGroup parent) {
    //    populateImages();
        ImageView imageView;
        if (convertView == null) {
            // if it's not recycled, initialize some attributes
            imageView = new ImageView(mContext);
            imageView.setLayoutParams(new GridView.LayoutParams(100, 100));
            imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            imageView.setPadding(1, 1, 1, 1);
            imageView.setImageResource(R.drawable.one);

        } else {
            imageView = (ImageView) convertView;
        }
        //imageView.setImageResource(R.drawable.two);
       // Log.d("getView", String.valueOf(values[position]));
        imageView.setImageResource(mThumbIds.get(position));

        return imageView;
    }





}
