我想限制未来的时间

Question

这是我的代码，我想限制将来的时间。

private TimePickerDialog.OnTimeSetListener timePickerListener = new TimePickerDialog.OnTimeSetListener() {

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minutes) {
            // TODO Auto-generated method stub

            hour = hourOfDay;
            minute = minutes;
            updateTime(hour, minute);
        }
    };
    private static String utilTime(int value) {
        if (value < 10)
            return "0" + String.valueOf(value);
        else
            return String.valueOf(value);
    }
    // Used to convert 24hr format to 12hr format with AM/PM values
    private void updateTime(int hours, int mins) {
        String timeSet = "";
        if (hours > 12) {
            hours -= 12;
            timeSet = "PM";
        } else if (hours == 0) {
            hours += 12;
            timeSet = "AM";
        } else if (hours == 12)
            timeSet = "PM";
        else
            timeSet = "AM";

        String minutes = "";
        if (mins < 10)
            minutes = "0" + mins;
        else
            minutes = String.valueOf(mins);
        // Append in a StringBuilder
        String aTime = new StringBuilder().append(hours).append(':')
                .append(minutes).append(" ").append(timeSet).toString();
        txttime.setText(aTime);
        SimpleDateFormat displayFormat = new SimpleDateFormat("HH:mm");
        SimpleDateFormat parseFormat = new SimpleDateFormat("hh:mm a");
        Date date = null;
        try {
            date = parseFormat.parse(aTime.toString());
        } catch (ParseException e) {
            e.printStackTrace();
        }
        System.out.println(parseFormat.format(date) + " = " + displayFormat.format(date));
        Log.e("date :", "date is " + displayFormat.format(date));
        timeconvert = displayFormat.format(date).toString();
        Log.e("timeconvert :", "time is " + timeconvert.toString());
    }**strong text**

最佳解决方案是使用此材料设计库选择时间或日期并设置最小值。

 TimePickerDialog tpd = TimePickerDialog.newInstance(
        new TimePickerDialog.OnTimeSetListener() {
            @Override 
            public void onTimeSet(TimePickerDialog view, int hourOfDay, int minute, int second) {
                //put some interesting code 
            } 
        }, 
        now.get(Calendar.HOUR_OF_DAY),
        now.get(Calendar.MINUTE),
        true 
    ); 
       Calendar now = Calendar.getInstance();
        Timepoint mTimepoint = new Timepoint( now.get(Calendar.HOUR),now.get(Calendar.MINUTE),now.get(Calendar.SECOND));
        tpd.setMaxTime(mTimepoint);
    tpd.show(getFragmentManager(), "TimePickerDialog");

将材料DateTime Picker库添加到您的项目的最简单方法是将其添加为您的build.gradle

dependencies {
    compile 'com.wdullaer:materialdatetimepicker:3.0.0'
}

Answer 2

Calendar now = Calendar.getInstance();
 timePickerDialog.setMaxTime(now.get(Calendar.HOUR_OF_DAY), now.get(Calendar.MINUTE),now.get(Calendar.SECOND));}
