附：一些相关的布局文件

PopupWindow弹出菜单

activity_popupwindow_main.xml 
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    android:background="#fff" >    <Button android:id="@+id/popBtn" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="弹出左侧菜单" /> </LinearLayout>

activity_popupwindow_left.xml 
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:background="@android:color/darker_gray"    android:orientation="vertical"    android:gravity="center"    android:paddingTop="50dp">    <Button        android:id="@+id/open"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_weight="1"        android:background="@android:color/darker_gray"        android:text="打开" />    <Button        android:id="@+id/save"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_weight="1"        android:background="@android:color/darker_gray"        android:text="保存" />    <Button        android:id="@+id/close"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_weight="1"        android:background="@android:color/darker_gray"        android:text="关闭" />    <Button        android:id="@+id/open"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_weight="1"        android:background="@android:color/darker_gray"        android:text="打开" />    <Button        android:id="@+id/save"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_weight="1"        android:background="@android:color/darker_gray"        android:text="保存" />    <Button        android:id="@+id/close"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_weight="1"        android:background="@android:color/darker_gray"        android:text="关闭" />        <Button        android:id="@+id/open"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_weight="1"        android:background="@android:color/darker_gray"        android:text="打开" />    <Button        android:id="@+id/save"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_weight="1"        android:background="@android:color/darker_gray"        android:text="保存" />    <Button        android:id="@+id/close"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_weight="1"        android:background="@android:color/darker_gray"        android:text="关闭" />    </LinearLayout>

弹出动画XML

在res文件夹下，建立anim文件夹。写入如下两个文件。
弹出动画
in_lefttoright.xml 
<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" >    <!-- 定义从左向右进入的动画 -->    <translate        android:duration="500"        android:fromXDelta="-100%"        android:toXDelta="0" /></set>

弹回动画
out_righttoleft.xml 
<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" >    <!-- 定义从右向左动画退出动画 -->    <translate        android:duration="500"        android:fromXDelta="0"        android:toXDelta="-100%" /></set>

动画管理

在styles.xml中，添加如下管理代码。 
    <style name="AnimationFade">        <!-- PopupWindow左右弹出的效果 -->        <item name="android:windowEnterAnimation">@anim/in_lefttoright</item>        <item name="android:windowExitAnimation">@anim/out_righttoleft</item>    </style>
