First, Introduction

Slidingdrawer hides content outside the screen and allows users to display hidden content through handle. It can slide vertically or horizontally, it has two view components, one is the handle that can be dragged, the other is the view of the hidden content. The controls inside it must be laid out, and handle and content must be specified in the layout file.

For example, below

<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= "This is an example of a sliding drawer"
Android:id= "@+id/tv"
