一次创建多个时间选择器 class

Question

我需要创建 3 个时间选择器并将它们存储在 SQLite 中。但我不知道。任何意见和建议将不胜感激。

public class Main extends AppCompatActivity implements View.OnClickListener{
 private TimePick tp;

    public void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.tableworkdetails);
                setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
                tp = new TimePick();
                start = (EditText) findViewById(R.id.editTextTI1);
                end = (EditText) findViewById(R.id.editTextTO1);
                start1 = (EditText) findViewById(R.id.editTextTI2);
                end1 = (EditText) findViewById(R.id.editTextTO2);
                start2 = (EditText) findViewById(R.id.editTextTI3);
                end2 = (EditText) findViewById(R.id.editTextTO3);
                editTextH1=(EditText)findViewById(R.id.editTextH1); // display total hours based on user input 
                start.setOnClickListener(this);
                end.setOnClickListener(this);
                start1.setOnClickListener(this);
                end1.setOnClickListener(this);
                start2.setOnClickListener(this);
                end2.setOnClickListener(this);
        }

         public void onClick(View v) {
                int id = v.getId();
                if (id == R.id.editTextTI1){
                    tp.setFlag(TimePick.FLAG_START_DATE);
                    FragmentTransaction ft = getFragmentManager().beginTransaction();
                    tp.show(ft, "TimePicker");
                } else if (id == R.id.editTextTO1) {

                    FragmentTransaction ft = getFragmentManager().beginTransaction();
                    tp.show(ft, "TimePicker");
                }
            }

        public static class TimePick extends android.app.DialogFragment implements TimePickerDialog.OnTimeSetListener {

    public static final int FLAG_START_DATE = 0;
    public static final int FLAG_END_DATE = 1;
    private int flag = 0;
                @Override
                public Dialog onCreateDialog(Bundle savedInstanceState)
                {
                    final Calendar c= Calendar.getInstance();
                    int hour=c.get(Calendar.HOUR_OF_DAY);
                    int minute=c.get(Calendar.MINUTE);

                    return new TimePickerDialog(getActivity(),this,hour,minute, DateFormat.is24HourFormat(getActivity()));
                }

                public void setFlag(int i) {
                    flag = i;
                }

                @Override
                public void onTimeSet(TimePicker view,int hourofDay, int minute)
                {

                    if (flag == FLAG_START_DATE) {
                        start.setText(Integer.toString(hourofDay) + ":" + Integer.toString(minute));
                        b=start.getText().toString();
                    } else if (flag == FLAG_END_DATE) {
                        end.setText(Integer.toString(hourofDay) + ":" + Integer.toString(minute));

                    }

                    SimpleDateFormat format= new SimpleDateFormat("HH:mm");
                    try {
                        Date date1 = format.parse(b);
                        Date date2 = format.parse(c);
                        long difference = date2.getTime() - date1.getTime();
                        int minutes = (int) ((difference/ (1000*60)) % 60);
                        int hours   = (int) ((difference/ (1000*60*60)) % 24)-1;
                        editTextH1.setText((hours+":"+minutes));

                    }catch (Exception e)
                    {
                        ....
                    }


                }


            }

        }

我对 Android 平台完全陌生，找不到任何与我的主题相关的网站。
