布局文件activity_main.xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context="com.example.android_datepicker.MainActivity" >    <TextView        android:id="@+id/textView"        android:layout_width="fill_parent"        android:layout_height="wrap_content" />    <DatePicker        android:id="@+id/datePicker"        android:layout_width="match_parent"        android:layout_height="wrap_content" />    <TimePicker        android:id="@+id/timePicker"        android:layout_width="match_parent"        android:layout_height="wrap_content" /></LinearLayout>
