resolved. see singularhum's answer below.

i have sliding menu option points fragment. fragment inflates layout using oncreateview. update values of list in onactivitycreated . here source.

my listview

public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {     this.dateformat = new simpledateformat("dd/mm/yyyy hh:mm", locale.getdefault());     this.portfolio = new portfolio();     this.portfolio.addcompanynoupdate("yhoo");      // specify fragment layout file fragment class     view view = inflater.inflate(r.layout.fragment_stock, container, false);     progresstext = (textview) view.findviewbyid(r.id.progresstextview);      // assign our cursoradapter     adapter = new quoteadapter(getactivity(), portfolio.getquotes());     listview list = (listview) view.findviewbyid(r.id.list);     list.setadapter(adapter);      adapter.notifydatasetchanged();       return view; } 

then have onactivitycreated doing update.

public void onactivitycreated(bundle savedinstancestate) {     super.oncreate(savedinstancestate);       this.update(); } 

my update class

private void update() {     // if network connection available, update stock information     if (utils.isnetworkavailable(getactivity())) {         // start custom task downloads data on thread ui not lock         new updatequotestask().execute(portfolio);     }     else {         // otherwise display error message user         this.progresstext.settext(this.getresources().getstring(r.string.no_internet_connection));     } } 

my adapter

public class quoteadapter extends baseadapter {    private context     context;   private list<quote> quotes;     public quoteadapter(context c, list<quote> quotes) { this.context = c; this.quotes = quotes; }   public void addquote(quote q) { this.quotes.add(q); }  @override public int getcount() { return this.quotes.size(); }  @override public object getitem(int position) { return this.quotes.get(position); } public long getitemid(int position) { // can return default value adapter return 0; }   @override public view getview(int position, view convertview, viewgroup parent) { miniquoteview miniquoteview = new miniquoteview(this.context,     this.quotes.get(position)); miniquoteview.setlayoutparams(new listview.layoutparams(listview.layoutparams.fill_parent, listview.layoutparams.wrap_content));  return miniquoteview; }  public void removeitem(int position) { this.quotes.remove(position); } } 

and xml standard listview

<relativelayout     android:layout_width="fill_parent"     android:layout_height="fill_parent">      <textview          android:id="@+id/progresstextview"          android:layout_width="match_parent"          android:layout_height="wrap_content"          android:text="@string/none" />      <listview         android:id="@+id/list"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:gravity="center"         android:verticalspacing="2dp"         android:layout_below="@+id/progresstextview" /> </relativelayout> 

for reason listview turns out empty. see image. can see debugger has values adapter.

here related miniquoteview class , xml

i believe issue in filldata method in miniquoteview class.

your first if statement is:

if (this.quote == null) 

but not have else or else if statement when quote object not null.

then if @ second if statement (which reads quote data , sets views) inside first one, is:

if (this.quote.name != null) 

which never true because quote null within if. why not seeing in list view because nothing being set displayed.

so should this:

if (this.quote == null) {     // displaying not available message } else if (this.quote.name != null){     // code display data }
