layout文件下 activity_main.xml (布局文件的代码)

<RelativeLayout 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: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=".MainActivity" >    <android.support.v4.widget.DrawerLayout        xmlns:android="http://schemas.android.com/apk/res/android"        android:id="@+id/drawer_layout"        android:layout_width="match_parent"        android:layout_height="match_parent" >        <FrameLayout                        android:id="@+id/content_frame"            android:layout_width="match_parent"            android:layout_height="match_parent" />                  <ListView                       android:id="@+id/left_drawer"            android:layout_width="240dp"            android:layout_height="match_parent"            android:layout_gravity="left"            android:background="#ffffff"            android:choiceMode="singleChoice"            android:divider="@android:color/transparent"            android:dividerHeight="0dp" />            </android.support.v4.widget.DrawerLayout></RelativeLayout>

values 文件下 strings.xml （包含一个数组）

<?xml version="1.0" encoding="utf-8"?><resources>    <string name="app_name">Android_v4_DrawerLayout</string>    <string name="action_settings">Settings</string>    <string name="hello_world">Hello world!</string>    <string name="drawer_open">打开</string>    <string name="drawer_close">关闭</string>    <string-array name="allCity">        <item>北京</item>        <item>上海</item>        <item>深圳</item>        <item>广州</item>        <item>郑州</item>        <item>香港</item>></string-array></resources>
