Android: ArrayAdapter getView() method is not executed

In My Project I have to display a list of reports. So In Activity page I write the following code

super.onCreate(savedInstanceState);
         setContentView(R.layout.report_full);
          List<Employee> data = new ArrayList<Employee>();
             Employee eg=new Employee();
             ListView li=(ListView)findViewById(R.id.report_list);
             Intent myIntent = getIntent(); // this is just for example purpose
             Bundle b=myIntent.getExtras();
             Log.i("User Report", b.toString());
             Toast.makeText(getApplicationContext(), "User Report", Toast.LENGTH_LONG).show();
             if(b !=null)
             {
                 String username = b.getString("username");
                 String userid = b.getString("userid");
                 String startdate = b.getString("startdate");
                 String enddate = b.getString("enddate");
                 String mode=b.getString("mode");
                 Log.i("LOOP", userid+"-"+startdate+"-"+enddate+"-"+mode);
                 data=eg.getTimeEntryUserReports(username, userid, startdate, enddate,mode);
                 Log.i("Get Report",data.toString());
                 li.setAdapter(new UserReportArrayadapter(this, data));
             }
 

And In UserReportArrayadapter.java , I write the following code,

    private LayoutInflater inflater;
     private List<EmployeeGlobal> data;
     public UserHoursByReportArrayadapter(Context context, List<EmployeeGlobal> objects) {
         super(context, R.layout.list_time_mode_report, objects);
         Log.i("User Report by HoursAdapter","Inside constructor");
         inflater = LayoutInflater.from(context);
         this.data = objects;
 }
 
     @Override
     public int getCount() {
         // TODO Auto-generated method stub
         return 1;
     }
 
     @Override
     public View getView(int position, View convertView, ViewGroup parent) {
         ViewHolder holder;
         Log.i("User Report by HoursAdapter","Inside getView");
         //if it's not create convertView yet create new one and consume it
           if(convertView == null){
             //instantiate convertView using our employee_list_item
               convertView = inflater.inflate(R.layout.list_time_mode_report, null);
               //get new ViewHolder
                 holder =new ViewHolder();
                //get all item in ListView item to corresponding fields in our ViewHolder class
                  holder.project=(TextView)convertView.findViewById(R.id.time_entry_1);
                 holder.hours=(TextView)convertView.findViewById(R.id.time_entry_2);
 
               //set tag of convertView to the holder
               convertView.setTag(holder);
          }
         //if it's exist convertView then consume it
           else {
                holder =(ViewHolder) convertView.getTag();
            }      
              //set data to holder
           Log.i("User Report by HoursAdapter:data",data.get(position).getData());
             holder.project.setText(data.get(position).getData());
             holder.hours.setText(data.get(position).getNo_of_hrs());
 
            return convertView;
       }
          //ViewHolder class that hold over ListView Item
          static class ViewHolder{
              TextView hours;
              TextView project;
 
 
         }
 

On Running this application, there is no items displayed in screen. And I have noticed that getView() method is not being called.
Please provide me the solution for this problem
