Try to add your string at the end of your class or remove all the parcelable generated code, add your string, then apply again the parcelable implementation.
This happens because you're not updating the parcel methods.

recycleview doesn't fetch json data

I have movie android app which contain recycleview with it's adapter and network it with api json data so when I run the app it installed and open but I get a white empty contain there is no data (images) in recycleview and don't now why

Type mismatch: cannot convert from String to List<Cmd>

I'm getting the follwoing error:
Type mismatch: cannot convert from String to List
on the line this.videos = videos; from the following code:
public void setVideos(String videos) {
this.videos = videos;
}
I've tried following both of Eclipse's suggestions:
Change type of videos to string
Change type of videos to List
However, neither seems to resolve the issue and both cause additonal errors.
I'm not sure exactly what I can do to resolve the issue at this point.

Update the setter method for variable List<Cmd> videos as below :

}

setVideos(String videos) should be defined as setVideos(List<Cmd> videos)

Android / Java - ListView Populated with XML Data Using ArrayList: Only Displays First Item

I'm attempting to populate a ListView with XML Data by using an ArrayList - which I've been able to accomplish thus far - the issue is the ArrayList does not seem to populate the ListView with data beyond the first item in the listView and I'm unsure why.

P.S.
If any additional information is required - please let me know (I will be at my desk working on this for the next few hours and will gladly answer any questions and accept any answers promptly)

In SAXXMLHandler.java's endElement() method you only add the cmd to the videos list if qName.equalsIgnoreCase("videos").
In all other cases you modify the cmd but you dont actually add it to the list. You want to add a videos.add(cmd) statement in the else if blocks as well so all the cmd's get added to the list.
This mistake right here is the cause of your List<Cmd> videos only having one item and thus only showing one item in your listview.

Try
Change

To
plistView = (ListView) getActivity().findViewById(R.id.plistView);
And also
public void onActivityCreated(Bundle state) {
super.onActivityCreated(state);
(new AsyncListViewLoader()).execute(url);
adapter = new AdaptadorPublicaciones(new ArrayList<Publicaciones>(), getActivity());
plistView = (ListView)getView().findViewById(R.id.plistView);
plistView.setAdapter(adapter);
}
To
public void onActivityCreated(Bundle state) {
super.onActivityCreated(state);
(new AsyncListViewLoader()).execute(url);
plistView = (ListView)getView().findViewById(R.id.plistView);
}
and
protected void onPostExecute(List<Publicaciones> result){
super.onPostExecute(result);
dialog.dismiss();
adapter.setItemList(result);
adapter.notifyDataSetChanged();
}
To
protected void onPostExecute(List<Publicaciones> result){
super.onPostExecute(result);
dialog.dismiss();
adapter = new AdaptadorPublicaciones(result, getActivity());
plistView.setAdapter(adapter);
}
Edited:-
Change
JSONArray arr = new JSONArray(JSONResp);
for (int i = 0; i < arr.length(); i++) {
result.add(convertItem(arr.getJSONObject(i)));
}
To
JSONObject json=new JSONObject(JSONResp);
JSONArray arr=json.getJSONArray("publicaciones");
for (int i = 0; i < arr.length(); i++) {
result.add(convertItem(arr.getJSONObject(i)));
}
