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>
