SlidingDrawer是一种抽屉型的组件，当用户选中抽屉之后，会得到一些可以使用的“程序集”，这样当一个界面要摆放多个组件的时候，使用此组件就可以很好的解决布局空间紧张的问题。
在main.xml中
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<SlidingDrawer
android:id="@+id/slidingdrawer"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:handle="@+id/handle"
android:content="@+id/content">
<ImageView
android:id="@+id/handle"
android:src="@drawable/ico_left"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/content"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_horizontal">
</LinearLayout>
</SlidingDrawer>
</LinearLayout>
