android - Adapt chrisbanes ActionBar-PullToRefresh to Fragments(NavigationDrawer) -

okay here problem:

i want implement chrisbanes actionbar-pulltorefresh library fragments able use navigationdrawer.

https://github.com/chrisbanes/actionbar-pulltorefresh#fragments

.

chrisbanes says use fragments:

one thing note pulltorefreshattacher needs created in oncreate() phase of activity. if plan on using library fragments best practice activity create pulltorefreshattacher, , have fragments retrieve activity.

an example provided in fragment & tabs sample.

.

.

****here comes question: created pulltorefreshattacher in activity how hell pass pulltorefreshattacher fragments :s****

i have read bundles , getarguments() putserializable , parcelable :

passing object activity fragment

and read article in sth. ((myactivity ) getactivity()).getclassx() ; used.

call activity method fragment

but nothing understood/worked. :(

.

.

here navigationactivity , 1 example fragment.i have new android/java :)

    final string[] menuentries = {"start","datum","website","kunden"}; final string[] fragments = {         "com.blabla.mainfragment",         "com.blabla.onefragment",         "com.blabla.twofragment",         "com.blabla.kundenfragment", };  private actionbardrawertoggle drawertoggle; private drawerlayout draweradapter; private listview navlistadapter;     private pulltorefreshattacher mpulltorefreshattacher;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);       setcontentview(r.layout.navigation_layout);      mpulltorefreshattacher = pulltorefreshattacher.get(this);        arrayadapter<string> adapter = new arrayadapter<string>(getactionbar().getthemedcontext(), android.r.layout.simple_list_item_1, menuentries);      final drawerlayout drawer = (drawerlayout)findviewbyid(r.id.refresh_navwiev);     final listview navlist = (listview) findviewbyid(r.id.drawermenu);      draweradapter=drawer;     navlistadapter=navlist;      getactionbar().setdisplayhomeasupenabled(true);     getactionbar().sethomebuttonenabled(true);      drawertoggle = new actionbardrawertoggle(             this,              drawer,             r.drawable.navicon,             r.string.drawer_open,             r.string.drawer_close     ) {          /** called when drawer has settled in closed state. */         public void ondrawerclosed(view view) {          }          /** called when drawer has settled in open state. */         public void ondraweropened(view drawerview) {          }       };      drawer.setdrawerlistener(drawertoggle);        navlist.setadapter(adapter);     navlist.setonitemclicklistener(new onitemclicklistener(){         @override         public void onitemclick(adapterview<?> parent, view view, final int pos,long id){             drawer.setdrawerlistener( new drawerlayout.simpledrawerlistener(){                 @override                 public void ondrawerclosed(view drawerview){                     super.ondrawerclosed(drawerview);                     //runs on completly closed                 }             });              //runs onclick if not same fragment             if(getactionbar().gettitle()!= menuentries[pos])             {              bundle bundle=new bundle();             bundle.putstring("message", "from activity");              //fragment zusammenbauen             fragment myfragment=new fragment();             myfragment = fragment.instantiate(navigationactivity.this, fragments[pos]);             myfragment.setarguments(bundle);                   fragmenttransaction tx = getsupportfragmentmanager().begintransaction();                 tx.setcustomanimations(r.anim.fragmentfadein, r.anim.fragmentfadeout);                 tx.replace(r.id.navigationscreen, myfragment);                  tx.commit();                 getactionbar().settitle(menuentries[pos]);                 drawer.closedrawer(navlist);             }         }     });      bundle bundle=new bundle();  //     bundle.putint(pulltorefreshattacher., position);      //fragment zusammenbauen     fragment myfragment=new fragment();     myfragment = fragment.instantiate(navigationactivity.this, fragments[0]);     myfragment.setarguments(bundle);           fragmenttransaction tx = getsupportfragmentmanager().begintransaction();         tx.setcustomanimations(r.anim.fragmentfadein, r.anim.fragmentfadeout);         tx.replace(r.id.navigationscreen, myfragment);          tx.commit();  }  public boolean onkeyup(int keycode, keyevent event) {     if (keycode == keyevent.keycode_menu) {          log.i("flostemplate", "menu taste gedrückt");              if(draweradapter.isdraweropen(navlistadapter))             {             draweradapter.closedrawer(navlistadapter);             }             else             {             draweradapter.opendrawer(navlistadapter);             }          return true;     }     return super.onkeyup(keycode, event); }  @override protected void onpostcreate(bundle savedinstancestate) {     super.onpostcreate(savedinstancestate);     drawertoggle.syncstate(); }  @override public void onconfigurationchanged(configuration newconfig) {     super.onconfigurationchanged(newconfig);     drawertoggle.onconfigurationchanged(newconfig); }  @override public boolean onoptionsitemselected(menuitem item) {     if (drawertoggle.onoptionsitemselected(item)) {         return true;     }      return super.onoptionsitemselected(item); }  @override public boolean oncreateoptionsmenu(menu menu) {     getmenuinflater().inflate(r.menu.main, menu);     return true; }   } 

and fragment

public class mainfragment extends fragment  {  public static fragment newinstance(context context) {     mainfragment f = new mainfragment();     return f; }  @override public view oncreateview(layoutinflater inflater, viewgroup container,bundle savedinstancestate) {     view rootview = inflater.inflate(r.layout.fragment_main, container, false);        return rootview; }  } 

it kind if me ,i stuck @ point days :)

p.s. sorry bad language , not native speaker ;)

there demo code on github page:

https://github.com/chrisbanes/actionbar-pulltorefresh/blob/master/samples/actionbarcompat/src/java/uk/co/senab/actionbarpulltorefresh/samples/actionbarcompat/fragmenttabsactivity.java

add activity:

public pulltorefreshattacher getpulltorefreshattacher() {     return mpulltorefreshattacher; } 

and oncreateview in fragment:

pulltorefreshattacher mpulltorefreshattacher = ((navigationactivity) getactivity()).getpulltorefreshattacher(); 

a better approach use interface i'd recommend starting github example.
