更改日期選擇器對話框當前日期 - android java

Question

我可以更改當天的突出顯示（用紅色圈出）。這是當天顯示系統，但我的應用程序工作在不同的時區，所以我如何取消突出顯示當天或將其更改爲另一天。

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); 
}

你需要做的是顯示您的對話框初始化與應用程序很好的日期對話框之前。此代碼來自android應用程序。

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);
