this java class in accessing list not clickable

public class showcases extends activity{   listview listshowcase; edittext search;   listviewadapter adapter;     @override protected void oncreate(bundle savedinstancestate) {     // todo auto-generated method stub        super.oncreate(savedinstancestate);     setcontentview(r.layout.screen4);      listshowcase = (listview) findviewbyid(r.id.licases);     adapter = new listviewadapter(this);       listshowcase.setadapter(adapter);     listshowcase.setclickable(true);     listshowcase.setonitemclicklistener(new adapterview.onitemclicklistener() {          @override         public void onitemclick(adapterview<?> arg0, view view, int arg2,                 long arg3) {             // todo auto-generated method stub             string name = ((textview) view.findviewbyid(r.id.name)).gettext().tostring();             string cost = ((textview) view.findviewbyid(r.id.email)).gettext().tostring();             string description = ((textview) view.findviewbyid(r.id.mobile)).gettext().tostring();             string id = ((textview) view.findviewbyid(r.id.id)).gettext().tostring();             // starting new intent             intent in = new intent(getapplicationcontext(), companydetail.class);             in.putextra("name", name);             in.putextra("email", cost);             in.putextra("ff", description);             in.putextra("fff", id);             startactivity(in);         }      });       search=(edittext)findviewbyid(r.id.etcaseseacrh);      search.addtextchangedlistener(new textwatcher() {          @override         public void ontextchanged(charsequence s, int start, int before, int count) {             // call adapter current character filter          }          @override         public void beforetextchanged(charsequence s, int start, int count,int after) {         }                  @override         public void aftertextchanged(editable arg0) {             // todo auto-generated method stub           }     });   } 

and getview of custom listadapter class

@override     public view getview(final int paramint, view paramview,          final viewgroup paramviewgroup) {       // todo auto-generated method stub       layoutinflater inflator = activity.getlayoutinflater();       if (paramview == null) {          view = new viewholder();          paramview = inflator.inflate(r.layout.list_item, null);          view.name = (textview) paramview.findviewbyid(r.id.name);          view.email = (textview) paramview.findviewbyid(r.id.email);          view.mobile = (textview) paramview.findviewbyid(r.id.mobile);          view.id = (textview) paramview.findviewbyid(r.id.id);         paramview.settag(view);        } else {          view = (viewholder) paramview.gettag();       }       view.name.settext(tag_name.get(paramint));      view.email.settext(tag_email.get(paramint));      view.mobile.settext(tag_phone_mobile.get(paramint));      view.id.settext(tag_id.get(paramint));      /*view.name.setfocusableintouchmode(false);      view.name.setfocusable(false);*/      /*view.setonclicklistener(myclicklistener);*/      view.name.setfocusable(false);      view.email.setfocusable(false);      view.mobile.setfocusable(false);      view.id.setfocusable(false);      return paramview;  }
