日期选择器和时间选择器-设置最大值和最小值

试试这个：

btnDate.setonClickListener(new View.onClickListener() {    @Override    public void onClick(View v) {        final DatePickerDialog.onDateSetListener datePickerListener = new DatePickerDialog.onDateSetListener() { @Override public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { }        };        Calendar c = Calendar.getInstance();        int mYear = c.get(Calendar.YEAR);        int mMonth = c.get(Calendar.MONTH);        int mDay = c.get(Calendar.DAY_OF_MONTH);        final DatePickerDialog datePickerDialog = new DatePickerDialog(     Main23Activity.this, datePickerListener,     mYear, mMonth, mDay);        DatePicker datePicker = datePickerDialog.getDatePicker();        c.add(Calendar.MONTH, +1);        long oneMonthAhead = c.getTimeInMillis();        datePicker.setMaxDate(oneMonthAhead);        datePicker.setMinDate(System.currentTimeMillis() - 1000);        datePickerDialog.show();    }});btnTime.setonClickListener(new View.onClickListener() {    @Override    public void onClick(View v) {        TimePickerDialog.onTimeSetListener timePickerListener = new TimePickerDialog.onTimeSetListener() { @Override public void onTimeSet(TimePicker view, int hour, int minute) { }        };        Calendar c = Calendar.getInstance();        final TimePickerDialog timePickerDialog = new TimePickerDialog(Main23Activity.this,timePickerListener,     c.get(Calendar.HOUR_OF_DAY),c.get(Calendar.MINUTE)+5,false);        timePickerDialog.show();    }});

但是，您需要检查用户是否选择了今天的日期，并且时间是否小于当前时间条件。
