android - How to add SurfaceView on top of Google Map Streetview? -

how can display surfaceview on streetmaps view , draw bitmap on surfaceview? surfacecreated() override method not being called.

here surfaceview class

public class streetviewoverlay extends surfaceview implements surfaceholder.callback {      bitmap mbitmap;     context mcontext;      public streetviewoverlay(context context, int bitmap) {         super(context);          mbitmap = bitmapfactory.decoderesource(getresources(), bitmap);         this.mcontext = context;     }      public streetviewoverlay(context context) {         super(context);     }      public streetviewoverlay(context context, attributeset attrs) {         super(context, attrs);     }      public streetviewoverlay(context context, attributeset attrs, int defstyleattr) {         super(context, attrs, defstyleattr);     }      @override     public void surfacecreated(surfaceholder holder) {         canvas canvas = null;         try {             canvas = holder.lockcanvas(null);             synchronized (holder) {                 ondraw(canvas);             }         } catch (exception e) {             e.printstacktrace();         } {             if (canvas != null) {                 holder.unlockcanvasandpost(canvas);             }         }     }      @override     public void surfacechanged(surfaceholder holder, int format, int width, int height) {     }      @override     public void surfacedestroyed(surfaceholder holder) {     }      @override     protected void ondraw(canvas canvas) {         canvas.drawcolor(color.transparent);         canvas.drawbitmap(mbitmap, 30, 30, new paint());     }  } 

inside of fragment, displaying streetmap view this

@override public void onstreetviewpanoramaready(streetviewpanorama streetviewpanorama) {     if (streetviewpanorama != null) {         // instantiate street view panorama object         mstreetviewpanorama = streetviewpanorama;         // set user navigation enabled false         mstreetviewpanorama.setusernavigationenabled(false);         // set onstreetviewpanoramachangelistener         mstreetviewpanorama.setonstreetviewpanoramachangelistener(new streetviewpanorama.onstreetviewpanoramachangelistener() {             @override             public void onstreetviewpanoramachange(streetviewpanoramalocation streetviewpanoramalocation) {                 if (streetviewpanoramalocation != null &&                         streetviewpanoramalocation.links != null) {                      // location available                     streetviewpanoramacamera camera = new streetviewpanoramacamera.builder()                             .bearing((float) (sphericalutil.computeheading                                     (mstreetviewpanorama.getlocation().position, latlng)))                             .build();                     // set street view camera face stop                     mstreetviewpanorama.animateto(camera, 150);                  }             }         });     } } 

in oncreateview() of fragment instantiate surfaceview overlay

streetviewoverlay streetviewoverlay = new streetviewoverlay(mcontext, r.drawable.ic_launcher); 

my xml looks this

<!-- street view --> <fragment     android:id="@+id/frag_streetview"     class="com.google.android.gms.maps.supportstreetviewpanoramafragment"     android:layout_width="match_parent"     android:layout_height="match_parent"/>  <com.example.utilities.map.streetviewoverlay     android:id="@+id/street_overlay"     android:layout_height="match_parent"     android:layout_width="match_parent"/>
