先贴代码：

Java：

public class MainActivity extends Activity {    private int year;    private int month;    private int day;    private int hour;    private int minute;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        DatePicker datePicker = (DatePicker) findViewById(R.id.datePicker);        TimePicker timePicker = (TimePicker) findViewById(R.id.timePicker);        //获取当前的年、月、日、小时、分钟        Calendar c = Calendar.getInstance();        year = c.get(Calendar.YEAR);        month = c.get(Calendar.MONTH);        day = c.get(Calendar.DAY_OF_MONTH);        hour = c.get(Calendar.HOUR);        minute = c.get(Calendar.MINUTE);        //初始化DatePicker组件，初始化是指定监视器        datePicker.init(year, month ,day, new DatePicker.OnDateChangedListener()        {                    @Override                    public void onDateChanged(DatePicker arg0, int year, int month, int day) {                        MainActivity.this.year = year;                        MainActivity.this.month = month;                        MainActivity.this.day = day;                        //显示当前日期、时间                        showDate(year, month, day, hour, minute);                    }        }        );        //为TimerPicker指定监听器        timePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {            @Override            public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {                MainActivity.this.hour = hourOfDay;                MainActivity.this.minute = minute;                //显示当前日期、时间                showDate(year, month, day, hour, minute);            }        });    }    //定义在EditText中显示当前日期、时间的方法    private void showDate(int year, int month, int day, int hour, int minute)    {        EditText show = (EditText) findViewById(R.id.show);        show.setText("你选择的日期为：" + year + "年" + month + "月" + day + "日" + hour + "时" + minute + "分");    }}

xml：

<?xml version="1.0" encoding="utf-8"?><LinearLayout        xmlns:android="http://schemas.android.com/apk/res/android"        android:orientation="vertical"        android:layout_width="match_parent"        android:layout_height="match_parent">    <TextView        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="选择具体时间"/>    <!--定义一个DatePicker组件-->    <DatePicker        android:id="@+id/datePicker"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center_horizontal"        android:startYear="2000"        android:endYear="2030"        android:calendarViewShown="true"        android:spinnersShown="true"></DatePicker>        <!--定义一个TimePicker组件-->    <TimePicker        android:id="@+id/timePicker"        android:layout_width="wrap_content"        android:layout_height="100dp"        android:layout_gravity="center_horizontal"></TimePicker>    <!--显示用户的输入日期、时间的控件-->    <EditText        android:id="@+id/show"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:editable="false"        android:cursorVisible="false"/></LinearLayout>

代码很浅显，应该都看得懂，一开始跟着书里敲代码，中间的日历只显示出星期的那一行，排错之后发现是DatePicker的高度设置不对，修改为warp_content.

效果图如下：
