如何在时间选择器中设置自定义时间

Question

TimePicker在TimePicker中显示当前时间作为默认时间，但是如果我想根据我的要求在时间选择器中设置默认时间呢?

当我写这篇文章的时候，它是11:10，但是在TimePicker中，我喜欢显示01:00作为默认值(我的平均2小时差，分钟应该只有00)

static final int TIME_DIALOG_ID = 1;
    public  int year,month,day,hour,minute;  
    private int mYear, mMonth, mDay,mHour,mMinute; 
    public TimePickerActivity() {
            // Assign current Date and Time Values to Variables
            final Calendar c = Calendar.getInstance();
            mYear = c.get(Calendar.YEAR);
            mMonth = c.get(Calendar.MONTH);
            mDay = c.get(Calendar.DAY_OF_MONTH);
            mHour = c.get(Calendar.HOUR_OF_DAY);
            mMinute = c.get(Calendar.MINUTE);
    }
    private TimePickerDialog.OnTimeSetListener mTimeSetListener =
        new TimePickerDialog.OnTimeSetListener() {
        public void onTimeSet(TimePicker view, int hourOfDay, int min) {
            hour = hourOfDay;
            minute = min;
            String formattedMinutes = "" + min;
            String formattedHour = "" + hourOfDay;
            if (hourOfDay < 10) {
                formattedHour = "0" + hourOfDay;
            }
            if (min < 10) {
                formattedMinutes = "0" + min;
            }
            textTime.setText(formattedHour + ":" + formattedMinutes);
        }
    };
  @Override
  protected Dialog onCreateDialog(int id) {
    switch (id) {
    case TIME_DIALOG_ID:
        TimePickerDialog timePickerDialog = new TimePickerDialog(this, mTimeSetListener, mHour, mMinute, false);
        return timePickerDialog;
    }
    return null;
}

Answer 1

您可以使用以下代码:

private TimePicker timePicker;
    timePicker = (TimePicker) dialog.findViewById(R.id.timePickerDialog);
    if(DateFormat.is24HourFormat(getActivity()){
        timePicker.setIs24HourView(true);
    }else {
        timePicker.setIs24HourView(false);
    }
    // here you can define your hour and minute value.
    timePicker.setCurrentHour(hour);
    timePicker.setCurrentMinute(minute);

Answer 2

你可以试试下面的代码

     SimpleDateFormat sdf = new SimpleDateFormat("hh:ss");
    Date date = null;
    try {
        date = sdf.parse("07:00");
    } catch (ParseException e) {
    }
    Calendar c = Calendar.getInstance();
    c.setTime(date);
    TimePicker picker = new TimePicker(getApplicationContext());
    picker.setCurrentHour(c.get(Calendar.HOUR_OF_DAY));
    picker.setCurrentMinute(c.get(Calendar.MINUTE));
