SelectDateFragment

SelectDateFragment

public static class SelectDateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

        @Override
        public Dialog onCreateDialog(Bundle savedInstanceState) {
            final Calendar calendar = Calendar.getInstance();
            int yy = calendar.get(Calendar.YEAR);
            int mm = calendar.get(Calendar.MONTH);
            int dd = calendar.get(Calendar.DAY_OF_MONTH);
            return new DatePickerDialog(getActivity(), this, yy, mm, dd);
        }

        public void onDateSet(DatePicker view, int yy, int mm, int dd) {
            populateSetDate(yy, mm + 1, dd);
        }

        public void populateSetDate(int year, int month, int day) {
            if (iCal == 1) {
                txtDate1.setText(month + "/" + day + "/" + year);
            } else {
                txtDate2.setText(month + "/" + day + "/" + year);
            }

        }
    }

推荐答案

SelectDateFragment.onCreateDialog（FilteringFragment.java ：744）

SelectDateFragment.onCreateDialog(FilteringFragment.java:744)

            if (iCal == 1) {
                txtDate1.setText(month + "/" + day + "/" + year);
            } else {
                txtDate2.setText(month + "/" + day + "/" + year);
            }

        }
    }

试试这个。



声明这些变量

Try this.

Declare these variables

private DateDialog dialog;
boolean click=false;

处理时 imgCal1 点击 onCreate 方法

Handle this when imgCal1 is clicked in onCreate method

imgCal1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View arg0) {
                click=true;
                iCal = 1;
                Dialog dialogFrg=dialog.getDialog();
               if(dialogFrg!=null && dialogFrg.isShowing()) {
            // no need to call dialog.show(ft, "DatePicker");
        } else {
            FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
            dialog.show(ft, "DatePicker");
        }
            }
        });

之后只需加上这个

After that only add this

public static class DateDialog extends android.support.v4.app.DialogFragment implements DatePickerDialog.OnDateSetListener {

        public DateDialog() {
        }

        public Dialog onCreateDialog(Bundle savedInstanceState) //display calender
        {
            final Calendar c=Calendar.getInstance();
            int year=c.get(Calendar.YEAR);
            month=c.get(Calendar.MONTH);
            int day=c.get(Calendar.DAY_OF_MONTH);
            return new DatePickerDialog(getActivity(),this,year, month,day);
        }

        public void onDateSet(DatePicker view,int yy, int month, int day)
        {
           populateSetDate(yy, mm + 1, dd);
        }

        public void populateSetDate(int year, int month, int day) {
            if (iCal == 1) {
                txtDate1.setText(month + "/" + day + "/" + year);
            } else {
                txtDate2.setText(month + "/" + day + "/" + year);
            }
 
        }
    }

您的布局XML文件包含 DatePicker widget？

What does your layout XML file look like that contains the DatePicker widget?
