Android中实现日期时间选择器(DatePicker和TimePicker)

利用Android应用框架提供的DatePicker（日期选择器）和TimePicker（时间选择器），实现日期时间选择器。

Dialog的Content布局文件（date_time_dialog.xml）：

<span style="font-size:18px;"><?xml version="1.0" encoding="utf-8"?>  
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" 
    android:padding="10dip" >  

    <TextView 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:singleLine="true" 
        android:text="请选择日期" 
        android:textColor="#FFFFFF" 
        android:textSize="16sp" />  

    <DatePicker 
        android:id="@+id/date_picker" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:layout_marginTop="5dip" />  

    <TextView 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:layout_marginTop="10dip" 
        android:singleLine="true" 
        android:text="请选择时间" 
        android:textColor="#FFFFFF" 
        android:textSize="16sp" />  

    <TimePicker 
        android:id="@+id/time_picker" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:layout_marginTop="5dip" />  

</LinearLayout>
</span>
