java - 更改日期选择器对话框当前日期 - android java

Question

我可以更改当天的突出显示(以红色圈出)。这显示了当天的系统，但我的应用程序在不同的时区工作，所以我如何取消突出显示这一天或将其更改为另一天。

private void setDateTimeField() {
    billDate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            billDateDialog.show();
            billDateDialog.updateDate(billDateCal.get(Calendar.YEAR), billDateCal.get(Calendar.MONTH), billDateCal.get(Calendar.DAY_OF_MONTH));
        }
    });


    billDateDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {

        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {

            // Bills need to be set to 00.00 hours. DST needs to be ignored because changing to other timezones with no DST will cause problems with days changing to the day before.
            long correctedTime = new DayLightSavings(year, monthOfYear, dayOfMonth, timeZone).getCorrectedTime();
            billDateCal.setTimeInMillis(correctedTime);
            billDate.setText(dateFormatter.format(billDateCal.getTimeInMillis()));
        }

    },billDateCal.get(Calendar.YEAR), billDateCal.get(Calendar.MONTH), billDateCal.get(Calendar.DAY_OF_MONTH));

    // Do not allow selection of <= today's date.
    // TODO Dialogue needs to be based on timezone selection.
    long oneDay = TimeUnit.MILLISECONDS.convert(1, TimeUnit.DAYS);

    long oldRawOffset = TimeZone.getDefault().getRawOffset();
    long newRawOffset = timeZone.getRawOffset();
    long rawOffset = oldRawOffset - newRawOffset;
    // TODO fix dialogue to display the correct timezone current day.
    billDateDialog.getDatePicker().setMinDate(Calendar.getInstance().getTimeInMillis() + oneDay - rawOffset);
}

您需要做的是在显示对话框之前使用应用程序良好日期初始化对话框。此代码来自 Android 应用程序。

DatePicker datePicker = (DatePicker) billDateDialog.getDatePicker();
TimePicker timePicker = (TimePicker) findViewById(R.id.timepicker);

DateTime apptime = DateTime.now() ; //From your app, db or other 
int y    = apptime.getYear() ;
int m   = apptime.getMonthOfYear() - 1;      // Need to subtract 1 here.
int d     = apptime.getDayOfMonth();  
int h    = apptime.getHourOfDay();
int min = apptime.getMinuteOfHour();

//setters
datePicker.updateDate(y, m, d);            
timePicker.setCurrentHour(h);                    
timePicker.setCurrentMinute(min);
