如何从片段中检索gridview中的图像？

我只是从drawable中检索图像并使用基本适配器，但片段不显示任何图像 . 以下是我的代码......有任何问题或逻辑错误......有人能告诉我!!!这是片段代码..

public View onCreateView（LayoutInflater inflater，ViewGroup container，Bundle savedInstanceState）{//为此片段扩展布局View view = inflater.inflate（R.layout.fragment_all_question，container，false）; GridView gridview =（GridView）view.findViewById（R.id.gridview）; imageAdapter = new ImageAdapter（mContext）; gridview.setAdapter（imageAdapter）;

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

    return view;
}

这是适配器代码

        // if it's not recycled, initialize some attributes

        imageView = new ImageView(mContext);
        imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
        imageView.setPadding(8, 8, 8, 8);
    } else {
        imageView = (ImageView) convertView;
    }

    imageView.setImageResource(mThumbIds[position]);
    return imageView;
}
// references to our images
private Integer[] mThumbIds = {
        R.drawable.sample_2, R.drawable.sample_3,
