Android: Custom listview on a fragment gets concatenated to previously appearing one, once created i want it to display the saved instance only

manpreet Best Answer 2 years ago

Everytime I go to some other fragment of my app Oncreate is called again and list duplicates itself. I'm a newbee to android soo it would be great to have some detailed solutions.

This is my Java code for the fragment:

public class Fragment_notice extends Fragment {
private static final String TAG = MainActivity2.class.getSimpleName();
private static final String STATE_NOTICE ="state_notice" ;
private ListView listView;
private JSONObject jobj;
private NoticeAdapter listAdapter;
int count=0;
ArrayList<NoticeItem> originalValues = new ArrayList<NoticeItem>();
private List<NoticeItem> feedItems;



private String URL_FEED = "http://calinfo.in/tiya/notice2.php";
@Nullable
@SuppressLint("NewApi")
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v=inflater.inflate(R.layout.noticereal_layout,container, false);
    listView = (ListView) v.findViewById(R.id.listnotice);
    if (savedInstanceState !=null)
    {
        feedItems=savedInstanceState.getParcelableArrayList(STATE_NOTICE);
        listAdapter = new NoticeAdapter(getActivity(), feedItems);
        listView.setAdapter(listAdapter);
    }
    else {

        feedItems = new ArrayList<NoticeItem>();

        listAdapter = new NoticeAdapter(getActivity(), feedItems);
        listView.setAdapter(listAdapter);


        // We first check for cached request
        ConnectionDetector cd = new ConnectionDetector(getActivity());

        Boolean isInternetPresent = cd.isConnectingToInternet();
        Cache cache = AppController.getInstance().getRequestQueue().getCache();

        Cache.Entry entry = cache.get(URL_FEED);
        if (!isInternetPresent) {
            AlertDialog showAlertDialog;
            showAlertDialog(getActivity(), "No Internet Connection",
                    "You don't have internet connection.", false);

            
                                                

                                                                                                        REPLY
                                                    
                                                
                                                


                                                    

                                                        
                                                            0
                                                            views 

                                                            0
                                                                likes 
                                                            
                                                            

                                                            0
                                                            shares
