*  点击后出现一个Dialog,点击Dialog选择日期和时间:
 *  选择日期：

//Calender是为了获取当前系统时间
            Calendar calendar = Calendar.getInstance();
                    calendar.setTimeInMillis(System.currentTimeMillis());
                    int year = calendar.get(Calendar.YEAR);
                    int monthOfyear = calendar.get(Calendar.MONTH);
                    int dayOfMonth = calendar.get(Calendar.DAY_OF_MONTH);
            //弹出新的对话框以进行新的时间选择
                    DatePickerDialog datePickerDialog = new DatePickerDialog(MainActivity.this, new DatePickerDialog.OnDateSetListener() {
                        @Override
                        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                            String DateTime = (String.format("%d-%d-%d", year, monthOfYear+1, dayOfMonth));//对日期格式进行转换
                            //将选中的时间设置为TextView的Text
                TextView Date = (TextView) findViewById(R.id.tvDate);
                            Date.setText(DateTime);
                        }
                    }, year, monthOfyear, dayOfMonth);
                    datePickerDialog.show();

*  选择时间：

Calendar calendar = Calendar.getInstance();
                    int hourOfDay = calendar.get(Calendar.HOUR_OF_DAY);
                    int minute = calendar.get(Calendar.MINUTE);
                    new TimePickerDialog(MainActivity.this, new TimePickerDialog.OnTimeSetListener() {
                        @Override
                        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                            String Datetime = (String.format("%d:%d", hourOfDay, minute));//对时间格式进行转换
                //将选中的时间设置为TextView的Text
                            TextView Time = (TextView) findViewById(R.id.tvTime);
                            Time.setText(Datetime);
                        }
                    },hourOfDay,minute,true).show();
