一、简介
? SlidingDrawer隐藏屏外的内容，并允许用户通过handle以显示隐藏内容。它可以垂直或水平滑动，它有俩个View组成，其一是可以拖动的handle,其二是隐藏内容的View.它里面的控件必须设置布局，在布局文件中必须指定handle和content.
例如下面
<SlidingDrawer android:layout_width="fill_parent"
??android:layout_height="fill_parent" android:handle="@+id/handle"
??android:content="@+id/content" android:orientation="vertical"
??android:id="@+id/slidingdrawer">
??<ImageButton android:id="@id/handle" android:layout_width="50dip"
?? android:layout_height="44dip" android:src="@drawable/up" />
??<LinearLayout android:id="@id/content"
???android:layout_width="fill_parent" android:layout_height="fill_parent"?
???android:background="#ffffff">
???<TextView android:text="这是一个滑动式抽屉的示例"?
???android:id="@+id/tv"
???android:textSize="18px"
???android:textColor="#000000"
???android:gravity="center_vertical|center_horizontal"
???android:layout_width="match_parent"?
???android:textStyle="bold"
???android:layout_height="match_parent"></TextView>
??</LinearLayout>

二、重要属性
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（手柄）
三、重要方法
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
?android:layout_width="fill_parent" android:layout_height="fill_parent"
?android:orientation="vertical" android:background="@drawable/default_bg">
?<SlidingDrawer android:layout_width="fill_parent"
??android:layout_height="fill_parent" android:handle="@+id/handle"
??android:content="@+id/content" android:orientation="vertical"
??android:id="@+id/slidingdrawer">
??<ImageButton android:id="@id/handle" android:layout_width="50dip"
?? android:layout_height="44dip" android:src="@drawable/up" />
??<LinearLayout android:id="@id/content"
???android:layout_width="fill_parent" android:layout_height="fill_parent"?
???android:background="#ffffff">
???<TextView android:text="这是一个滑动式抽屉的示例"?
???android:id="@+id/tv"
???android:textSize="18px"
???android:textColor="#000000"
???android:gravity="center_vertical|center_horizontal"
