android - How to refresh a Fragment with a View object -

i'm building classic menu/detail fragment tablet activity.

my detail fragment graph generate external library. libray giving me intent or view of graph.

when i'm clicking on menu want refresh graph.

this activity code :

public class myactivity extends fragmentactivity {  context context; graphical graphical;  @override protected void oncreate(bundle savedinstancestate) {      super.oncreate(savedinstancestate);     context = this;     setcontentview(r.layout.fragment_suivi_conso_graph); }  /**  * called when clicking on menu fragment  */ public void onchoosegraph(urlaction urlaction){     graphfragment graphfragment = (graphfragment)                         getsupportfragmentmanager().findfragmentbyid(r.id.graph_fragment);      if (graphfragment == null || !graphfragment.isinlayout()) {         intent intentgraph;     intentgraph = graphical.executeforintent(this, urlaction);     startactivity(intentgraph);     }      else {        view graphview = graphfragment.loadgraph(urlaction);            // don't know view !     } } 

this detail fragment code :

public class graphfragment extends fragment {  private context context; private graphical graphical;  @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate)  {     super.oncreate(savedinstancestate);      context = this.getactivity();     graphical = new graphical();      view graphview = null;         graphview = graphical.executeforview(context, urlaction.conso_weeks);     return graphview; }  public view loadgraph(urlaction urlaction) {     log.d("graphfragment","[loadgraph] start");     view graphview = graphical.executeforview(context, urlaction);             //this graphview contains graph want display in graphfragment     return graphview; }  } 

i don't know if can reload fragment view loadgraph function of fragment. or need on activity onchoosegraph function.

in both case, don't know how refresh.

i found solution :

on detail fragment : graphfragment, here proper loadgraph methode :

    public void loadgraph(urlaction urlaction) {     log.d(tag,"[loadgraph] start, urlaction : " + urlaction);      view graphview = null;     try {         graphview = graphical.executeforview(context, urlaction);     } catch (exception e) {         log.e(tag, "[loadgraph] error during parsing : "+e.getmessage());         e.printstacktrace();         if(e.getmessage().equals(xmlparsersuivitconso.xml_is_error)){             toast.maketext(context, getstring(r.string.checkyouparameters), toast.length_long).show();             intent intentsettings = new intent(context, settingsactivity.class);             startactivity(intentsettings);             getactivity().finish();         }     }      setfragmentcontentview(graphview); }  void setfragmentcontentview(view view) {     linearlayout.layoutparams layoutparams =              new linearlayout.layoutparams(viewgroup.layoutparams.fill_parent,                                            viewgroup.layoutparams.fill_parent);     mrootlayout.removeallviews();     mrootlayout.addview(view, layoutparams); } 

and on activity myactivity using following code call loadgraph :

    public void onchoosegraph(urlaction urlaction){     graphfragment graphfragment = (graphfragment) getsupportfragmentmanager().findfragmentbyid(r.id.graph_fragment);     // on essaye de récupérer notre fragment.      // s'il n'est pas présent, on le crée en lançant son activity     if (graphfragment == null || !graphfragment.isinlayout())      {         intent intentgraph;         try {             intentgraph = graphical.executeforintent(this, urlaction);             startactivity(intentgraph);         } catch (exception e) {             log.e(tag, "[onlistitemclick] error during parsing : "+e.getmessage());             e.printstacktrace();             if(e.getmessage() == null || e.getmessage().equals(xmlparsersuivitconso.xml_is_error)){                 toast.maketext(this, getstring(r.string.checkyouparameters), toast.length_long).show();                 intent intentsettings = new intent(this, settingsactivity.class);                 startactivity(intentsettings);                 finish();                 return;             }         }     }      else      // sinon on met à jour le choix de l'utilisateur     {        graphfragment.loadgraph(urlaction);     } 

i hope 1 !
