android - Can't get my ListView items to be highlighted when they are selected -

i have app hits rest service, gets json , places listview. main activity extends activity , not listactivity. can scroll through list items, cannot select (at least touch). listview through findviewbyid , have adapter extends simpleadapter. have set convertview inside adapter's getview() clickable. when this, can no longer click on list items in listview? did wrong?

public class app extends activity {     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.main);         jobslistview = (listview) findviewbyid(r.id.jobs_list);         jobslistview.setadapter(new jobitemadapter(jobslistview.getcontext(),                  jobslist,                  r.layout.list_item,                  new string[] {"title","location"},                 new int[] {r.id.job_title, r.id.job_location}));         jobslistview.setonitemclicklistener(new adapterview.onitemclicklistener() {              @override             public void onitemclick(adapterview<?> arg0, view arg1, int arg2,                     long arg3) {                 // todo auto-generated method stub                 log.i("jobslistview.setonitemclicklistener()"," item clicked: " + arg0.getselecteditemposition());             }          });      }      public class jobitemadapter extends simpleadapter {         private list<hashmap<string,string>> jobslist;          public jobitemadapter(context context, list<hashmap<string,string>> jobs, int resource, string[] from, int[] to)         {                super(context, jobs, resource, from, to);             jobslist = jobs;                     }          public view getview(int position, view convertview, viewgroup parent){             log.i(tag," in  jobitemadapter getview() ");              if (convertview == null) {                 //no previous views, inflate views                 convertview = getlayoutinflater().inflate(r.layout.list_item, parent, false);             }              //update textviews in layout             textview title = (textview)convertview.findviewbyid(r.id.job_title);             title.settext(jobslist.get(position).get("title"));              textview location = (textview)convertview.findviewbyid(r.id.job_location);             location.settext(jobslist.get(position).get("location"));             //make view clickable             convertview.setclickable(true);             return convertview;         }      }  } 

probably can happening defining background color row, defined in r.layout.list_item, , background color not color defined in selector, example:

<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android">     <item android:state_pressed="true" >          <shape android:shape="rectangle">              <solid                 android:color="@color/blue_button_press"/>          </shape>      </item>      <item android:state_selected="true" >          <shape android:shape="rectangle">              <solid                 android:color="@color/blue_button_focus" />          </shape>      </item>      <item android:state_focused="true" >          <shape android:shape="rectangle">              <solid                 android:color="@color/blue_button_focus" />          </shape>      </item>      <item>          <shape android:shape="rectangle" >             <solid                 android:color="@color/white" />          </shape>      </item>  </selector> 

in it, can define color each state of view, in case: focused , pressed. in order use it, in r.layout.list_item, set background normaly, example

android:background="@drawable/list_row_background" 

considering xml file file described aboved named list_row_background , in drawable folder

and shouldn't set clickable, since clickable. hope solves problem :d cheers
