fragment

公共(public)类 MyFragment 扩展 fragment {

private static String bitmap = "thumbnailUrl";

    // TODO Auto-generated method stub
    View myFragmentView = inflater.inflate(R.layout.fragment_full, container, false);

    Bundle bundle = this.getArguments();
    String page = bundle.getString("images", bitmap);

    ImageLoader imageLoader = AppController.getInstance().getImageLoader();
    final NetworkImageView thumbNail = (NetworkImageView)myFragmentView.findViewById(R.id.thumbnail);
    thumbNail.setImageUrl(page, imageLoader);
 return myFragmentView;
    }

}

**注意:**Listview to fulldetail image getting properply but not getting to my frament from details Activity

Answer 1

通过 fragment 的 setArguments() 方法传递图像 url，并使用 getArguments() 在 fragment 中获取它。
