android - How to use ListFragment with BaseAdpater and Json file -

i have json displaying fine in listview when using customadapter extends baseadpater. in tests, can parse , inflate listview fine when reading json file when not loading fragment.

i need move this/display in fragment. fragment extending listfragment. cannot listfragment display.

this code fragment:

public class activitysearchresultstwo extends listfragment {  private listfragment mlistview;  public static activitysearchresultstwo newinstance() {     activitysearchresultstwo fragment = new activitysearchresultstwo();     return fragment; }  public activitysearchresultstwo() { }  @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {     view root = inflater.inflate(r.layout.fragment_session_row, null);     return root; }  @override public void onactivitycreated(bundle savedinstancestate) {     super.onactivitycreated(savedinstancestate);     mlistview = (listview) findviewbyid(r.id.list);     arraylist<sessions> sessionslist = sessions.getrecipesfromfile("recipes.json",getactivity());     sessionslistadapter adapter = new sessionslistadapter(getactivity(),sessionslist);     setlistadapter(adapter);     //getlistview().setonitemclicklistener(this); } 

}

my listview declared follows:

  <listview     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:id="@+id/list"     android:background="@color/colorprimarylight"/> 

this relevant extract object class

public class sessions {   public static arraylist<sessions> getrecipesfromfile(string filename, context context){     final arraylist<sessions> recipelist = new arraylist<>(); 

// rest of parsing of json file....//

and adapter listing....

public class sessionslistadapter extends baseadapter {  private context mcontext; private layoutinflater minflater; private arraylist<sessions> mdatasource;  public sessionslistadapter(context context, arraylist<sessions> items) {     mcontext = context;     mdatasource = items;     minflater = (layoutinflater) mcontext.getsystemservice(context.layout_inflater_service); }  //1 @override public int getcount() {     return mdatasource.size(); }  //2 @override public object getitem(int position) {     return mdatasource.get(position); }  //3 @override public long getitemid(int position) {     return position; }  //4 @override public view getview(int position, view convertview, viewgroup parent) {      viewholder holder;      // 1     if(convertview == null) {          // 2         convertview = minflater.inflate(r.layout.fragment_session_row, parent, false);           // 3         holder = new viewholder();          //holder.noofplacestextview = (textview) convertview.findviewbyid(r.id.noofplaces);         holder.remainingplacestextview = (textview) convertview.findviewbyid(r.id.remainingplaces);         holder.activitytimetextview = (textview) convertview.findviewbyid(r.id.activitytime);         holder.activitypricetextview = (textview) convertview.findviewbyid(r.id.activityprice);          // 4         convertview.settag(holder);     }     else{         // 5         holder = (viewholder) convertview.gettag();     }      // 6    // textview noofplacestextview = holder.noofplacestextview;     textview remainingplacestextview = holder.remainingplacestextview;     textview activitytimetextview = holder.activitytimetextview;     textview activitypricetextview = holder.activitypricetextview;       sessions session = (sessions) getitem(position);      // 2    // noofplacestextview.settext(session.places);     remainingplacestextview.settext(session.remaining + " / " + session.places + " left");     activitytimetextview.settext(session.eventtime);     activitypricetextview.settext(session.price);      // 3     //picasso.with(mcontext).load(provider.imageurl).placeholder(r.mipmap.ic_launcher).into(thumbnailimageview);      return convertview; }  private static class viewholder {     public textview remainingplacestextview;     public textview activitytimetextview;     public textview activitypricetextview; } 

}

any appreciated list displaying in fragment. thanks

found problem, did not update oncreateview in fragment activity list layout...i still had set show previous layout using test.

view root = inflater.inflate(r.layout.fragment_session_list, container, false);

setting below solved issue.
