Android:Datepicker对话框放入选项卡时会导致崩溃

我已经成功地创建了一个日期选择器对话框，并在其中一个选项卡中添加了该对话框。但是我想要实现的是在一个选项卡中创建一个选项卡，该选项卡的内容就是我的日期选择器。问题是它崩溃了

所以基本上我想要实现的就是这样

日期选择器的代码段

inputDate.setOnClickListener(new OnClickListener() {

            public void onClick(View view)


            {
                int mYear, mMonth, mDay;

                final Calendar c = Calendar.getInstance();
                mYear = c.get(Calendar.YEAR);
                mMonth = c.get(Calendar.MONTH);
                mDay = c.get(Calendar.DAY_OF_MONTH);
                DatePickerDialog dpd = new DatePickerDialog(Act.this,
                    new DatePickerDialog.OnDateSetListener() {
                        public void onDateSet(DatePicker view, int year, int month, int day) {

                            c.set(year, month, day);
                            String date = new SimpleDateFormat("yyyy/MM/dd").format(c.getTime());
                            inputStart.setText(date);

                            int mYear = c.get(Calendar.YEAR);
                            int mMonth = c.get(Calendar.MONTH);
                            int mDay = c.get(Calendar.DAY_OF_MONTH);

                             }
                    }, mYear, mMonth, mDay);


                    dpd.show();

            }
        });

看起来日期选择器试图添加到错误的活动中。你能帮我发一些密码吗？就像你调用dialogfragment.Done的那部分。非常感谢。你能详细说明一下你对错误活动的看法吗？我应该在哪一部分检查？什么是VacLeave.class？活动？我粘贴了错误的代码对不起。该类名称为actSo，请重新编辑并粘贴相关代码？

inputDate.setOnClickListener(new OnClickListener() {

            public void onClick(View view)


            {
                int mYear, mMonth, mDay;

                final Calendar c = Calendar.getInstance();
                mYear = c.get(Calendar.YEAR);
                mMonth = c.get(Calendar.MONTH);
                mDay = c.get(Calendar.DAY_OF_MONTH);
                DatePickerDialog dpd = new DatePickerDialog(Act.this,
                    new DatePickerDialog.OnDateSetListener() {
                        public void onDateSet(DatePicker view, int year, int month, int day) {

                            c.set(year, month, day);
                            String date = new SimpleDateFormat("yyyy/MM/dd").format(c.getTime());
                            inputStart.setText(date);

                            int mYear = c.get(Calendar.YEAR);
                            int mMonth = c.get(Calendar.MONTH);
                            int mDay = c.get(Calendar.DAY_OF_MONTH);

                             }
                    }, mYear, mMonth, mDay);


                    dpd.show();

            }
        });
