Android Rafraichir GridView
Bonjour,
J'essaie de refraichir une Gridview après avoir ajouté un item à la liste. Mais je n'y parvient pas.
Voici mon code:

if(meslisteModels.get(position).getAvatar()!=null)
{
Log.e("getView",meslisteModels.get(position).getAvatar());
int loader = R.drawable.ic_loader;
String url = meslisteModels.get(position).getAvatar();
ImageLoader imageLoader = ImageLoader.getInstance();
DisplayImageOptions options = new DisplayImageOptions.Builder().cacheInMemory(true)
.cacheOnDisc(true).resetViewBeforeLoading(true)
.showImageForEmptyUri(loader)
.showImageOnFail(loader)
.showImageOnLoading(loader).build();
//download and display image from url
imageLoader.displayImage(url, imgView, options);
}
}
return rowView;
}
public ListListeModelAdapter(FragmentActivity activity, List<ListeModel> listsOffre) {
super();
// super(activity, R.layout.listview_listemodel, listsOffre);
mActivity=activity;
mContext = activity.getApplicationContext();
meslisteModels = listsOffre;
mInflater = LayoutInflater.from(mContext);
}
@Override
public int getCount() {
// TODO Auto-generated method stu
return meslisteModels.size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return meslisteModels.get(position);
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public void notifyDataSetChanged() {
// TODO Auto-generated method stub
super.notifyDataSetChanged();
}
} |
Je sais pas si le problème provient ImageLoader, car lorsque meslisteModels.get().getAvatar() est vide la GridView se rafraichi correctement avec l'image par défaut.
