}

//this populated listview

 private void populateemploymenthistorylist() {     listemployeehistory = (listview) findviewbyid(r.id.listemployeehistory);      emphistory = dbhelper.getallemploymenthistory();     employmenthistoryadapter = new employmenthistoryadapter(emphistory,this);     listemployeehistory.setadapter(employmenthistoryadapter); } 

//this layout file added listview , have custom design list_row

you need specify height listview in xml code. wrap_content not expand listview when data inflated it. specify height 200dp or something.
