如何根据我在另一个日期选择器上选择的“FromDate”在日期选择器上设置“ToDate”的最小日期

Question

简而言之，我有两个日期选择器（从、到）。我选择“FromDate”和“ToDate”直到当前日期。

如果我选择 2019-04-04 到“FromDate”，当我选择“ToDate”时，它应该隐藏“FromDate”之前的日期。我怎样才能做到这一点？

mFromEditTextBox.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        DatePickerDialog fromPicker = new DatePickerDialog(getActivity(), date, myCalendar
                .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                myCalendar.get(Calendar.DAY_OF_MONTH));

        fromPicker.getDatePicker().setMaxDate(System.currentTimeMillis() - 1000);
        fromPicker.show();

        clickedView = (EditText) v;
    }
});

mToEditTextBox.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {

        DatePickerDialog toPicker = new DatePickerDialog(getActivity(), date, myCalendar
                .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                myCalendar.get(Calendar.DAY_OF_MONTH));
        toPicker.getDatePicker().setMaxDate(System.currentTimeMillis()-1000);
        toPicker.show();
        clickedView = (EditText) v;
    }
});

您需要为 toDate 选择器设置一个最短日期

mToEditTextBox.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {

        DatePickerDialog toPicker = new DatePickerDialog(getActivity(), date, myCalendar
                .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                myCalendar.get(Calendar.DAY_OF_MONTH));

        //set min date
        Date fromDate = parseFromDate();
        if (fromDate != null){
            toPicker.getDatePicker().setMinDate(fromDate.getTime());
        }

        toPicker.getDatePicker().setMaxDate(System.currentTimeMillis()-1000);
        toPicker.show();
        clickedView = (EditText) v;
    }
});

// returns date selected in mFromEditTextBox
private Date parseFromDate(){
    try{
        SimpleDateFormat f = new SimpleDateFormat("date format you used");
        return f.parse(mFromEditTextBox.getText().toString());
    } catch (Exception ex) {
        // from date is not selected
        // alert user to select from date
        return null;
    }
}

DatePicker

希望这会有所帮助！
