Android Apidemos Sample resolution (App->activity->setwallpaper)

SetWallpaper describes how to get the current wallpaper on Android, make some changes to wallpaper, and then reset wallpaper with the modified image.

Wallpapermanager is used to manage Android wallpaper. The following code uses Wallpapermanager to get the current wallpaper and then display it on the imageview of the screen layout.

Final Wallpapermanager Wallpapermanager     
 = wallpapermanager.getinstance (this);     
Final drawable wallpaperdrawable     
 = wallpapermanager.getdrawable ();     
Final ImageView ImageView     
 = (imageview) Findviewbyid (R.id.imageview);     
Imageview.setdrawingcacheenabled (true);     
Imageview.setimagedrawable (wallpaperdrawable);

Reset wallpaper, also through Wallpapermanager.

Wallpapermanager.setbitmap (Imageview.getdrawingcache ());
