Question

大家好我想在开始日期选择日期之后显示日期选择器（结束日期）。结束日期选择器将显示从日期之后的日期。结束日期将显示从日期之后和之前的日期选择器约会不会显示。我该怎么办？我正在尝试的是

       fromdate = (EditText) findViewById(fromDate);
       todate = (EditText) findViewById(R.id.todate);
       fromdate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            showTruitonDatePickerDialog(view);
        }
    });
    todate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            showToDatePickerDialog(view);
        }
    });
    }
public void showTruitonDatePickerDialog(View v) {
    DialogFragment newFragment = new DatePickerFragment();
    newFragment.show(getSupportFragmentManager(), "datePicker");
   }
 public void showToDatePickerDialog(View v) {
    DialogFragment newFragment = new ToDatePickerFragment();
    newFragment.show(getSupportFragmentManager(), "datePicker");
}
 public static class DatePickerFragment extends DialogFragment implements
        DatePickerDialog.OnDateSetListener {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current date as the default date in the picker
        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);

        // Create a new instance of DatePickerDialog and return it
        return new DatePickerDialog(getActivity(), this, year, month, day);
    }

    public void onDateSet(DatePicker view, int year, int month, int day) {
        // Do something with the date chosen by the user

        fromdate.setText(day + "/" + (month + 1) + "/" + year);
           }   }

public static class ToDatePickerFragment extends DialogFragment implements
       DatePickerDialog.OnDateSetListener {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current date as the default date in the picker
        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);

        // Create a new instance of DatePickerDialog and return it
        return new DatePickerDialog(getActivity(), this, year, month, day);
    }
   public void onDateSet(DatePicker view, int year, int month, int day) {
        // Do something with the date chosen by the user
        view.setMinDate(fromDate);
        todate.setText(day + "/" + (month + 1) + "/" + year); } }

Answer 1

尝试使用此代码

    public static boolean isDateAfter(String startDate,String endDate)
    {
    try
    {
        String myFormatString = "yyyy-M-dd"; // for example
        SimpleDateFormat df = new SimpleDateFormat(myFormatString);
        Date date1 = df.parse(endDate));
        Date startingDate = df.parse(startDate);

        if (date1.after(startingDate))
            return true;
        else
            return false;
    }
    catch (Exception e) 
    {

        return false;
    }
}

如果enddate在开始日期之后，则返回true。

     fromdate = (EditText) findViewById(fromDate);
    todate = (EditText) findViewById(R.id.todate);
    fromdate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            showTruitonDatePickerDialog(view);
        }
    });
    todate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            showToDatePickerDialog(view);
        }
    });
}
public void showTruitonDatePickerDialog(View v) {
    DialogFragment newFragment = new DatePickerFragment();
    newFragment.show(getSupportFragmentManager(), "datePicker");
}

public void showToDatePickerDialog(View v) {
    DialogFragment newFragment = new ToDatePickerFragment();
    newFragment.show(getSupportFragmentManager(), "datePicker");
}

public static class DatePickerFragment extends DialogFragment implements
        DatePickerDialog.OnDateSetListener {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current date as the default date in the picker
        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);
        DatePickerDialog datePickerDialog;
        datePickerDialog = new DatePickerDialog(getActivity(),this, year, 
        month,day);
        return datePickerDialog;
    }

    public void onDateSet(DatePicker view, int year, int month, int day) {
        // Do something with the date chosen by the user
        fromdate.setText(day + "/" + month  + "/" + year);
    }

}

public static class ToDatePickerFragment extends DialogFragment implements
        DatePickerDialog.OnDateSetListener {
   // Calendar startDateCalendar=Calendar.getInstance();
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current date as the default date in the picker
          String getfromdate = fromdate.getText().toString().trim();
          String getfrom[] = getfromdate.split("/");
        int year,month,day;
             year= Integer.parseInt(getfrom[2]);
             month = Integer.parseInt(getfrom[1]);
            day = Integer.parseInt(getfrom[0]);
        final Calendar c = Calendar.getInstance();
        c.set(year,month,day+1);
        DatePickerDialog datePickerDialog = new DatePickerDialog(getActivity(),this, year,month,day);
       datePickerDialog.getDatePicker().setMinDate(c.getTimeInMillis());
        return datePickerDialog;
    }
    public void onDateSet(DatePicker view, int year, int month, int day) {

        todate.setText(day + "/" + month  + "/" + year);
    }
}

我选择开始日期为.... 2009年1月1日然后我打开它显示的结束日期.... 2009年9月2日

Answer 3

定义startDateCalendar，如

Calendar startDateCalendar=Callendar.getInstance();

并更新片段代码

public static class DatePickerFragment extends DialogFragment implements
            DatePickerDialog.OnDateSetListener {

        @Override
        public Dialog onCreateDialog(Bundle savedInstanceState) {
            // Use the current date as the default date in the picker
            final Calendar c = Calendar.getInstance();
            int year = c.get(Calendar.YEAR);
            int month = c.get(Calendar.MONTH);
            int day = c.get(Calendar.DAY_OF_MONTH);
            DatePickerDialog datePickerDialog = new DatePickerDialog(mActivity,this, year, month,day);
            datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis());
            // Create a new instance of DatePickerDialog and return it
            return datePickerDialog;
        }

        public void onDateSet(DatePicker view, int year, int month, int day) {
            // Do something with the date chosen by the user

            fromdate.setText(day + "/" + (month + 1) + "/" + year);
            startDateCalendar.set(Calendar.YEAR, year);
            startDateCalendar.set(Calendar.MONTH, month);
            startDateCalendar.set(Calendar.DAY_OF_MONTH, day);
        }   }

    public static class ToDatePickerFragment extends DialogFragment implements
            DatePickerDialog.OnDateSetListener {

        @Override
        public Dialog onCreateDialog(Bundle savedInstanceState) {
            // Use the current date as the default date in the picker
            final Calendar c = Calendar.getInstance();
            int year = c.get(Calendar.YEAR);
            int month = c.get(Calendar.MONTH);
            int day = c.get(Calendar.DAY_OF_MONTH);

            DatePickerDialog datePickerDialog = new DatePickerDialog(getActivity(),this, startDateCalendar.get(Calendar.YEAR), startDateCalendar.get(Calendar.MONTH), startDateCalendar.get(Calendar.DAY_OF_MONTH));
            datePickerDialog.getDatePicker().setMinDate(startDateCalendar.getTimeInMillis());
            // Create a new instance of DatePickerDialog and return it
            return datePickerDialog;
        }
        public void onDateSet(DatePicker view, int year, int month, int day) {
            // Do something with the date chosen by the user
            view.setMinDate(fromDate);
            todate.setText(day + "/" + (month + 1) + "/" + year); } }

Answer 4

您可以将setMinDate和setMaxDate方法用于datepickerdialog。

例如： DatePicker toPicker = Util.getDatePicker（getActivity（），toDateSetListener，toYear，toMonth，toDay） .getDatePicker（）; toPicker.setMinDate（getToMinDate（））; toPicker.setMaxDate（System.currentTimeMillis的（））;

Answer 5

因此，当您关闭fromDate对话框时，只需将变量存储在类级别中。

fromYear fromMonth fromDay

然后当你启动toDate（fromYear，fromMonth，fromDay）到对话框而不是日历。获取当前日期，只需使用from并在当天添加+1以便在第二天启动选择器。有意义吗？

有一个名为MaterialDateRangePicker的库可以完全解决您的问题请找到链接 https://github.com/borax12/MaterialDateRangePicker

Android显示的datepicker（结束日期）是否大于开始日期？
