}
}
这是在Application里的配置
public class HeadFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
View view = inflater.inflate(R.layout.headfragment,container,false);
ImageView iv = (ImageView) view.findViewById(R.id.head_iv);
Bundle bundle = getArguments();
String headImageUrl = bundle.getString("headImageUrl");
Log.e("headImageUrl", headImageUrl);
GlobalApplication.imageLoader.displayImage(headImageUrl, iv,GlobalApplication.options);
return view;
}
}
这是用到的时候ImageLoader的时候。
但是老是报错，怎么回事啊
