android - Custom ListView does not show up -

i trying use custom listview inside fragment using custom cursoradapter, far unable display listview.

what doing wrong?

my fragment

import android.app.fragment; import android.os.bundle; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup; import android.widget.listview;  public class mylistfragment extends fragment {      private customcursoradapter mcustomcursoradapter;     private listview mlistview;      @override     public view oncreateview(layoutinflater inflater,                              viewgroup container,                              bundle savedinstancestate) {         view view = inflater.inflate(r.layout.fragment_mylist, container, false);          //cursoradapter         mcustomcursoradapter = new customcursoradapter(view.getcontext(), null, 0);          //listview         mlistview = (listview) view.findviewbyid(r.id.itemslist);         mlistview.setadapter(mcustomcursoradapter);          return view;     }      @override     public void onactivitycreated(bundle savedinstancestate) {         super.onactivitycreated(savedinstancestate);     } } 

my mainactivity

import android.app.activity; import android.app.fragmentmanager; import android.os.bundle;  public class mainactivity extends activity {      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          fragmentmanager fragmentmanager = getfragmentmanager();         if (fragmentmanager.findfragmentbyid(android.r.id.content) == null) {             mylistfragment mylistfragment = new mylistfragment();             fragmentmanager.begintransaction().add(android.r.id.content, mylistfragment).commit();         }     } } 

customcursoradapter

import android.content.context; import android.database.cursor; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup; import android.widget.cursoradapter; import android.widget.textview;  public class customcursoradapter extends cursoradapter {      private layoutinflater mlayoutinflater;      public customcursoradapter(context context, cursor c, int flags) {         super(context, c, flags);         mlayoutinflater = (layoutinflater) context.getsystemservice(context.layout_inflater_service);     }      @override     public void bindview(view view, context context, cursor cursor) {         textview textview = (textview) view.findviewbyid(r.id.itemtextview);         textview.settext(cursor.getstring(cursor.getcolumnindex(databasehelper.column_name_item)));     }      @override     public view newview(context context, cursor cursor, viewgroup parent) {         return mlayoutinflater.inflate(r.layout.itemslist, parent, false);     } } 

here's doing.

in fragment, doing in onactivitycreated() this:

@override     public view oncreateview(layoutinflater inflater, viewgroup container,             bundle savedinstancestate) {          view campainview = inflater.inflate(r.layout.campaignview, container, false);          return campainview;     }      public void onactivitycreated(bundle savedinstancestate) {             // todo auto-generated method stub             super.onactivitycreated(savedinstancestate);              string[] s = {"a","b","c","d","b","c","d","b","c","d","b","c","d","b","c","d","b","c","d"};              arraylist<string> alist = new arraylist<string>();              for(string s1:s){                  alist.add(s1);              }              listview lv1= (listview)getactivity().findviewbyid(r.id.campaignlistview);             lv1.setadapter(new arrayadapter<string>(getactivity(), android.r.layout.simple_list_item_1,alist));          } 

this work's me , can instead of using adapter iv'e used, can use cursor adapter. if it's still not working, issue cursor adapter or values null that's coming database.

let me know if working.. luck .. :)
