public class menucatfragment extends listfragment {
       //android studio auto-generated code ommitted      public menucatfragment() {   }
         @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     if (getarguments() != null) {         mparam1 = getarguments().getstring(arg_param1);         mparam2 = getarguments().getstring(arg_param2);     }      myapp = (app)this.getactivity().getapplication();     currentrestosummary = myapp.getselectedrestosummary();     restoid = currentrestosummary.getrestoid();  try {        loadselectedresto();     } catch (exception e) {     }  }  private void loadselectedresto() throws jsonexception {       eatnowrestclient.get("resto", new requestparams("id", restoid), new jsonhttpresponsehandler() {           @override         public void onsuccess(int statuscode, header[] headers, jsonobject response) {              gson gson = new gson();             type listtype = new typetoken<resto>() {}.gettype();              try {                 resto = gson.fromjson(response.tostring(), listtype);                  myapp.setselectedresto(resto);                  filllistview();                  //progressdialog.dismiss();               } catch (exception e) {                  throw e;             }         }           @override         public void onfailure(int statuscode, header[] headers, throwable throwable, jsonobject errorresponse) {             super.onfailure(statuscode, headers, throwable, errorresponse);             //progressdialog.dismiss();             //log.d("failed: ", ""+statuscode);             //log.d("error : ", "" + throwable);         }      });  private void filllistview() {  listadapter adapter;  adapter  = new customadaptermenucat(getactivity(),r.layout.custom_row_menucat,resto.getmenu_categories());  setlistadapter(adapter);      }   }  //adapter code  public class customadaptermenucat extends arrayadapter<menucategory> {  menucategory[] menucat; context c;  public customadaptermenucat(context context, int resource, menucategory[] objects) {     super(context, resource, objects);      menucat = objects;     c = context; }  @override public int getcount() {     return menucat.length; }  @override public menucategory getitem(int position) {     return menucat[position]; }  @override public long getitemid(int position) {     return position; }  @override public view getview(int position, view convertview, viewgroup parent) {      view customview = view.inflate(c, r.layout.custom_row_menucat,null);      textview lblmenucatnameresto = (textview)customview.findviewbyid(r.id.lblmenucat);      lblmenucatnameresto.settext(menucat[position].getname());      return customview;   } 

}

i found solution...the issue fragmenttabhost layout xml...below working one.

<android.support.v4.app.fragmenttabhost      android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:id="@+id/tabresto">      <framelayout         android:id="@android:id/tabcontent"         android:layout_width="match_parent"         android:layout_height="wrap_content" />      <linearlayout         android:layout_width="match_parent"         android:layout_height="match_parent"         android:orientation="vertical">          <tabwidget             android:id="@android:id/tabs"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:layout_gravity="bottom"/>          <framelayout             android:id="@+id/realtabcontent"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:layout_weight="1"/>      </linearlayout> </android.support.v4.app.fragmenttabhost>
