SlidingDrawer

  SlidingDrawer(隐藏式抽屉),它配置上采用了水平展开和垂直展开两种（android：orientation）方式，在XML里必须指定其使用的android:handle和android:content,前者委托要展开的图片（点击的那个控件来打开抽屉），后者则是要展开的Layout Content（打开抽屉后的内容）。还是很简单的。
配置文件：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
<SlidingDrawer
    android:id="@+id/drawer1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:handle="@+id/myImage1"
    android:content="@+id/myContent1"
    android:orientation="horizontal"
    >
    <LinearLayout
    	android:id="@+id/layout1"
    	android:layout_width="35px"
    	android:layout_height="fill_parent"
    	android:gravity="center">
    	<ImageView
    		android:id="@id/myImage1"
    		android:layout_width="wrap_content"
    		android:layout_height="wrap_content"
    		android:src="@drawable/left"/>
    </LinearLayout>
    <GridView
        android:id="@id/myContent1"
        android:layout_width="wrap_content"
    	android:layout_height="wrap_content"
    	android:numColumns="2"
    	android:gravity="center"
    	android:background="@color/black"/>
</SlidingDrawer>
</RelativeLayout>
