使用DatePickerDialog和TimePickerDialog設置時間

在點擊Button後彈出的DatePickerDialog中設置好日期後，調用onDateSet()函數，在onDateSet()中又顯示一個TimePickerDialog，實現“同時”設置日期和時間。

        Button.setOnClickListener(new OnClickListener(){
            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub

                //獲取一個現在時間
                final Time now = new Time();
                now.setToNow();

                new DatePickerDialog(MainActivity.this, new OnDateSetListener(){

                    @Override
                    public void onDateSet(DatePicker arg0, int year, int month, int day) {
                        // TODO Auto-generated method stub
                        now.year = year;
                        now.month = month;
                        now.monthDay = day;

                        new TimePickerDialog(MainActivity.this, new OnTimeSetListener(){
                            @Override
                            public void onTimeSet(TimePicker arg0, int hour, int minute) {
                                // TODO Auto-generated method stub
                                now.hour = hour;
                                now.minute = minute;
                            }} , now.hour, now.minute, true).show();
                    }}, now.year, now.month, now.monthDay).show();
            }
        });
