/**
* SlidingDrawer hides content out of the screen and allows the user to drag a handle to bring the content on screen. SlidingDrawer can be used
* vertically or horizontally.
*
* A special widget composed of two children views: the handle, that the users drags, and the content, attached to the handle and dragged with it.
*
* SlidingDrawer should be used as an overlay inside layouts. This means SlidingDrawer should only be used inside of a FrameLayout or a RelativeLayout
* for instance. The size of the SlidingDrawer defines how much space the content will occupy once slid out so SlidingDrawer should usually use
* match_parent for both its dimensions.
*
* Inside an XML layout, SlidingDrawer must define the id of the handle and of the content:
*
* <pre class="prettyprint">
* &lt;SlidingDrawer
* android:id="@+id/drawer"
* android:layout_width="match_parent"
* android:layout_height="match_parent"
*
* android:handle="@+id/handle"
* android:content="@+id/content"&gt;
*
* &lt;ImageView
* android:id="@id/handle"
* android:layout_width="88dip"
* android:layout_height="44dip" /&gt;
*
* &lt;GridView
* android:id="@id/content"
* android:layout_width="match_parent"
* android:layout_height="match_parent" /&gt;
*
* &lt;/SlidingDrawer&gt;
