listview中的android评级栏:如何保存对象中多个列表的评级?

标签: android ratingbar

我正在设计教师反馈活动。下面是我的片段活动,我从webservice获取教师姓名作为对象,并在listview中显示它们。并且每个教师都有评级栏。

我想在对象数组中收集评级和教员姓名的值,并且当我点击提交按钮时想要将每个教师的反馈发送到webservice存储。我该怎么办?

FragmentTab2.java

public class TabFragment2 extends android.support.v4.app.Fragment implements View.OnClickListener {
    ListView FacultyList;
    View rootView;
    LinearLayout courseEmptyLayout;

    FacultyListAdapter facultyListAdapter;
Button upButton;
    String feedbackresult,programtype,programname;
    Boolean FeedBackResponse;

    String FacultiesList[];
   public ArrayList<Faculty> facultylist = new ArrayList<Faculty>();

    SharedPreferences pref;
    FacultyListAdapter adapter;
    SessionSetting session;

    public TabFragment2(){
    }



    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        pref = getActivity().getSharedPreferences("prefbook", getActivity().MODE_PRIVATE);
        programtype = pref.getString("programtype", "NOTHINGpref");

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {


        rootView = inflater.inflate(R.layout.activity_studenttab2, container, false);
        upButton = (Button) rootView.findViewById(R.id.btnSubmit);

        session = new SessionSetting(getActivity());

        new FacultySyncerBg().execute("");

        courseEmptyLayout = (LinearLayout) rootView.findViewById(R.id.feedback_empty_layout);

                courseEmptyLayout.setVisibility(LinearLayout.GONE);
        }


        @Override
        public View getView(final int position, View convertView,

                    else
                    {
                        facultyListAdapter.notifyDataSetChanged();
                    }
                }
                else
                {
                    FacultyList.setAdapter(facultyListAdapter);
                }

            {
                courseEmptyLayout.setVisibility(LinearLayout.VISIBLE);
               // FacultyList.setVisibiltity(View.GONE) ;

            }



            progressDialog.dismiss();

        }
    }

这是我的对象类

Faculty.java

public class Faculty {
    private float ratingStar;
    String employeeid;
    String employeename;

    //public List<Faculty> facultylist= new ArrayList<>();

    public Faculty()
    {

    }
    public Faculty(int ratingStar,String employeeid,String employeename)
    {
        this.ratingStar = ratingStar;
        this.employeeid =employeeid;
        this.employeename =employeename;
    }

    public float getRatingStar() {
        return ratingStar;
    }

    public void setRatingStar(float ratingStar) {
        this.ratingStar = ratingStar;
    }

    public  void setEmployeeid(String employeeid)
    {
        this.employeeid = employeeid;
    }

    public String getEmployeeid()
    {
        return this.employeeid;
    }

    public  void setEmployeename(String employeename)
    {
        this.employeename = employeename;
    }

    public String getEmployeename()
    {
        return this.employeename;
    }
}
