From setting up static wallpapers, to live wallpapers, to lock screen wallpapers, to themes, it's not that simple.

1. Set Static wallpaper

Mainactivity.java

public class Mainactivity extends Activity {@Overrideprotected void onCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview (r.layout.activity_main); Wallpapermanager = Wallpapermanager.getinstance (This ); Registerreceiver (Broadcastreceiver, New Intentfilter (intent.action_wallpaper_changed));} Wallpapermanager wallpapermanager;public void OnClick (View v) {switch (V.getid ()) {case R.id.btn_setwallpaper:file File = New File (environment.getexternalstoragedirectory () + "/pictures/field.png"); try {InputStream is = new FileInputStream (file);//contextwrapper method, readable bitmap, inputstream//need Set_wallpaper permission. Read files need write_external_storage permission SetWallpaper (IS);} catch (FileNotFoundException e) {e.printstacktrace ();} catch (IOException e) {e.printstacktrace ();} Break;case r.id.btn_setwallpaper2://can load res, InputStream, bitmaptry {wallpapermanager.setresource (R.drawable.frame) ;} catch (IOException e) {e.printstacktrace ();} Break;case r.id.btn_clearwallpaper://Clear Wallpaper try {wallpapermanager.clear ();} CATCH (IOException e) {e.printstacktrace ();}}} Receive wallpaper change broadcast private broadcastreceiver broadcastreceiver = new Broadcastreceiver () {@Overridepublic void OnReceive ( Context context, Intent Intent) {if (Intent.getaction (). Equals (intent.action_wallpaper_changed)) {Toast.maketext ( Mainactivity.this, "changed wallpaper", Toast.length_short). Show ();}};}

2. Set Live Wallpaper

Mywallpaperservice.java, selecting the current wallpaper from the Live wallpaper gallery will trigger the service instantiation and call Oncreateengine

/** * Wrapper service, used to instantiate and manage engine */public class Mywallpaperservice extends Wallpaperservice {private static final String TA G = MyWallpaperService.class.getSimpleName ();p ublic Mywallpaperservice () {super (); LOG.D (TAG, "Mywallpaperservice");} @Overridepublic Engine Oncreateengine () {LOG.D (TAG, "Oncreateengine"); return new Mywallpaperserviceengine (this);}}

Mywallpaperserviceengine.java

/** * Engine encapsulates a surfaceview * <p>surfaceview dual cache mechanism for displaying wallpaper: A front buffer, a back buffer. Assuming that the current display is front, if the content changes, * back on the original basis to draw the content. Then back and front swap positions. <P> */public class Mywallpaperserviceengine extends Wallpaperservice.engine {private static final String TAG = Mywal LpaperServiceEngine.class.getSimpleName ();//30 frameprivate/sec. static final int FPS = 5;private final Handler Handler = NE W Handler ();p ublic mywallpaperserviceengine (wallpaperservice wp) {wp.super ();p aint = new paint ();p Aint.setargb (255, 255, 255, 255);} @Overridepublic void OnCreate (Surfaceholder surfaceholder) {super.oncreate (surfaceholder);} @Overridepublic void onoffsetschanged (float xoffset, float yoffset,float xoffsetstep, float yoffsetstep, int Xpixeloffset,int ypixeloffset) {super.onoffsetschanged (Xoffset, Yoffset, Xoffsetstep, YOffsetStep, XPixelOffset, Ypixeloffset);} @Overridepublic void Ontouchevent (Motionevent event) {super.ontouchevent (event);} timer timer; @Overridepublic void onsurfacecreated (Surfaceholder holDer) {super.onsurfacecreated (holder); timer = new timer (); Timer.schedule (new TimerTask () {@Overridepublic void run () { Drawframe ();}}, 0, 1000/fps);} public void onsurfacedestroyed (Surfaceholder holder) {timer.cancel ();}; Paint paint;float y = 300f;private void Drawframe () {final Surfaceholder holder = Getsurfaceholder (); Canvas Canvas = Null;try{canvas = Holder.lockcanvas (new Rect (+, +, 1100)), if (canvas!=null) {//clear screen, Resets the pixel group Canvas.drawcolor (color.black);//Draw Canvas.drawcircle (300f, y, 200f, paint) on the canvas; y + = 20f;if (y>900f) {y = 300f;}}} Finally{if (canvas!=null) {holder.unlockcanvasandpost (canvas);}} Handler.removecallbacks (Drawsurface);//handler.postdelayed (Drawsurface, 1000/fps);} Private final Runnable drawsurface = new Runnable () {@Overridepublic void run () {drawframe ();}};}
