选择日期后，显示错误的月份 [英] After selecting date, its showing wrong month

问题描述

我正在使用日期选择器，但是无论何时选择显示-1个月份的任何日期。
例如-如果我选择12/12/2016，它将显示在文本框中12/11/2016
如果我选择3/1/2017，它将显示3/0/2017

I'm using datepicker, but whenever I'm selecting any date its showing -1 moneth. For example- If I select 12/12/2016, it'll display in textbox 12/11/2016 If I select 3/1/2017, it'll display 3/0/2017

这是我的日期选择器对话框的代码：

Here is my piece of code of datepicker dialog:

editStartDate.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Calendar mcurrentDate = Calendar.getInstance();
                    int mYear = mcurrentDate.get(Calendar.YEAR);
                    int mMonth = mcurrentDate.get(Calendar.MONTH);
                    int mDay = mcurrentDate.get(Calendar.DAY_OF_MONTH);

                    DatePickerDialog mDatePicker = new DatePickerDialog(TourActivity.this, new DatePickerDialog.OnDateSetListener() {
                        public void onDateSet(DatePicker datepicker, int selectedyear, int selectedmonth, int selectedday) {
                            Calendar newDate = Calendar.getInstance();
                            newDate.set(selectedyear, selectedmonth, selectedday);
                            editStartDate.setText(selectedday + "/" + selectedmonth + "/" + selectedyear);
                        }
                    }, mYear, mMonth, mDay);
                    mDatePicker.setTitle("Select date");
                    mDatePicker.show();

                }
            });

请建议我在哪里输入错误的代码。

Please suggest where I'm putting wrong code.

推荐答案

在这种情况下，月份计数从0开始。因此，您必须添加1才能显示。

In this case, the month count is started at 0. So you have to add 1 for display.

  editStartDate.setText(selectedday + "/" + (selectedmonth + 1) + "/" + selectedyear);

另请参阅以下问题以供参考：为什么Java日历中的1月为0？
