I. Introduction

Slidingdrawer hides content outside the screen and allows users to display hidden content through handle. It can slide vertically or horizontally. It consists of two views. One is the handle that can be dragged, and the other is the view that hides the content. the layout must be set for the controls in the layout file, and handle and content must be specified in the layout file.

For example

<Slidingdrawer Android: Id = "@ + ID/slidingdrawer" Android: layout_width = "fill_parent" Android: layout_height = "fill_parent" Android: content = "@ + ID/content" Android: handle = "@ + ID/handle" Android: Orientation = "vertical"> <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: Id = "@ + ID/TV" Android: layout_width = "match_parent" Android: layout_height = "match_parent" Android: gravity = "center_vertical | center_horizontal" Android: text = "this is an example of a sliding drawer" Android: textcolor = "#000000" Android: textsize = "18px" Android: textstyle = "bold"> </textview> </linearlayout> </sshortingdrawer>
