3. java 代码

datePicker = (DatePicker) findViewById(R.id.datePicker);
        mBtnCommit = (Button) findViewById(R.id.btnCommit);
        mTvTimeShow = (TextView) findViewById(R.id.tvTimeShow);
calendar = Calendar.getInstance();
        dateFormat = new SimpleDateFormat("yyyy年MM月dd日");
        mTvTimeShow.setText("服务起始日期:  "+dateFormat.format(calendar.getTime()));
        datePicker.init(calendar.get(calendar.YEAR), calendar.get(calendar.MONTH), calendar.get(calendar.DAY_OF_MONTH),
                new OnDateChangedListener(){
                    @Override
                    public void onDateChanged(DatePicker view, int year,
                            int month, int day) {
                        calendar.set(year, month, day);
                        mTvTimeShow.setText("服务起始日期:  "+dateFormat.format(calendar.getTime()));
                    }
        });
        /*timePicker.setIs24HourView(false);
        timePicker.setOnTimeChangedListener(new OnTimeChangedListener(){
            @Override
            public void onTimeChanged(TimePicker view, int hour, int minute) {
                //calendar.set(year, month, day, hourOfDay, minute);
            }
