android - 重新选择日期选择器后的日期选择器对话框显示当前日期

Question

我试图在再次选择时在日期选择器对话框中显示所选日期。

这是我尝试过的。

 signup.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {


             Calendar mcurrentDate=Calendar.getInstance();
                year=mcurrentDate.get(Calendar.YEAR);
                month=mcurrentDate.get(Calendar.MONTH);
                day=mcurrentDate.get(Calendar.DAY_OF_MONTH);

                DatePickerDialog mDatePicker=new DatePickerDialog(CreateAccountActivity.this, new OnDateSetListener()
                {   
                    @Override
                    public void onDateSet(DatePicker datepicker, int selectedyear, int selectedmonth, int selectedday) 
                    {
                            year = selectedyear; 
                            month = selectedmonth; 
                            day = selectedday;
                     signup.setText(new StringBuilder().append(year).append("-").append(month+1).append("-").append(day));
                    }
                },year, month, day);
                mDatePicker.setTitle("Please select date");                
                mDatePicker.getDatePicker().setMaxDate(System.currentTimeMillis());
                mDatePicker.show();


        }
    });

但问题是当我再次选择我的约会对象时。它显示当前日期。我想在对话框中显示选定的日期。

我已经解决了答案...

答案在这里....

public void onClick(View v) {

             if (year == 0 || month == 0 || day == 0) {
             Calendar mcurrentDate=Calendar.getInstance();
                year=mcurrentDate.get(Calendar.YEAR);
                month=mcurrentDate.get(Calendar.MONTH);
                day=mcurrentDate.get(Calendar.DAY_OF_MONTH);
             }

                DatePickerDialog mDatePicker=new DatePickerDialog(CreateAccountActivity.this, new OnDateSetListener()
                {   
                    @Override
                    public void onDateSet(DatePicker datepicker, int selectedyear, int selectedmonth, int selectedday) 
                    {
                            year = selectedyear; 
                            month = selectedmonth; 
                            day = selectedday;
                     signup.setText(new StringBuilder().append(year).append("-").append(month+1).append("-").append(day));
                    }
                },year, month, day);
                mDatePicker.setTitle("Please select date");                
                mDatePicker.getDatePicker().setMaxDate(System.currentTimeMillis());
                mDatePicker.show();
