1、抽屉功能，自己看很简单，代码拷贝自己跑一遍就知道了

2、注意点：

SlidingDrawer 这个值的xml中的属性中

SlidingDrawer控件的一些属性：

android:allowSingleTap 指示是否可以通过handle打开或关闭

android:animateOnClick 指示是否当使用者按下手柄打开/关闭时是否该有一个动画。

android:content 隐藏的内容
android:handle handle 点击内容

----xml--部分图片自己造几个

<? xml version= "1.0" encoding = "utf-8"?>

< RelativeLayout xmlns:android ="http://schemas.android.com/apk/res/android"

android:layout_width= "fill_parent"

android:layout_height= "fill_parent" >

<TextView android:layout_height = "wrap_content"

android:layout_width= "fill_parent"

android:text ="123456789\n 12312312312\n12312312312\n1312312312132"

android:gravity= "center_vertical|center_horizontal"

<SlidingDrawer

android:id= "@+id/sliding"

android:layout_width= "match_parent"

android:layout_height ="match_parent"

android:content= "@+id/allApps"

android:handle= "@+id/imageViewIcon"

android:orientation= "vertical" >

<GridView

android:id= "@+id/allApps"

android:layout_width= "wrap_content"

android:layout_height ="wrap_content"

android:background= "@drawable/one"

android:columnWidth= "60dp"

android:gravity= "center"

android:horizontalSpacing ="10dp"

android:numColumns= "auto_fit"

android:padding= "10dp"

<ImageView

android:id= "@+id/imageViewIcon"

android:layout_width= "wrap_content"

android:layout_height ="wrap_content"

android:src= "@drawable/two" />

</SlidingDrawer >

</ RelativeLayout>
