Android中實現日期時間選擇器(DatePicker和TimePicker)

利用Android應用框架提供的DatePicker（日期選擇器）和TimePicker（時間選擇器），實現日期時間選擇器。

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

    <?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="請選擇日期"  
            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="請選擇時間"  
            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>
