Android drawer Effect

Although the slidingdrawer class is no longer recommended, sometimes it can be used if the effect is simple. Anyway, I may miss it, mainly because it is easy to use and can only slide up or down or left or right, in addition, the direction cannot be specified at the beginning,

Layout File

<Linearlayout xmlns: Android = "http://schemas.android.com/apk/res/android"

Android: layout_width = "match_parent"

<LinearLayout

Android: layout_width = "match_parent"

Android: background = "#008800">
<TextView
Android: layout_width = "match_parent"
Android: layout_height = "match_parent"
Android: text = "hidden content"/>
</LinearLayout>
</SlidingDrawer>
<TextView
Android: layout_width = "match_parent"
Android: layout_height = "wrap_content"
Android: text = "bottom textView"
Android: textAppearance = "? Android: attr/textAppearanceLarge"
Android: gravity = "center_vertical | center_horizontal"/>
</LinearLayout>

You can slide without writing any code on the main interface,

If you want to write some methods, the following methods are used:

SlidingDrawer sd = (SlidingDrawer) findViewById (R. id. slidingdrawer );

Sd. setOnDrawerOpenListener (new OnDrawerOpenListener (){
Public void onDrawerOpened (){
// TODO Auto-generated method stub
}
});
Sd. setOnDrawerCloseListener (new OnDrawerCloseListener (){
Public void onDrawerClosed (){
// TODO Auto-generated method stub
}
});
Sd. setOnDrawerScrollListener (new OnDrawerScrollListener (){
Public void onScrollEnded (){
// TODO Auto-generated method stub
}
Public void onScrollStarted (){
// TODO Auto-generated method stub
}
});

The icon of the application on the hand machine in the lower drawer is displayed with a zoom icon in the drawer, Which is switched from the network. I think it may be useful in the future. If there is intrusion, please also inform
