4、对话框与菜单的使用：

DatePickerDialog的使用方法

首先调用Calendar类获取年月日

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

然后将获取到的年月日放进new出来的DatePickerDialog中

        DatePickerDialog datePickerDialog = new DatePickerDialog(getContext(),
                new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                        mYear = year;
                        mMonth = month;
                        mDay = dayOfMonth;
                        final String data =  (month+1) + "月-" + dayOfMonth + "日 ";
                         }
                },
                mYear, mMonth, mDay);
        datePickerDialog.show();
