android postDelayed method doesn't work -

-

i'm trying splash screen app. used postdelayed method. code:

   public class splashscreenactivity extends activity {      private static final int splash_duration_ms = 1500;      private static final string tag = splashscreenactivity.class.getsimplename();      private handler mhandler = new handler();      public static final int sdkversion = build.version.sdk_int;      @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.splash_screen);          random r = new random();         int imagenumber = r.nextint(2 - 0) + 0;          imageview splashscreenbackground = (imageview)findviewbyid(r.id.splash_screen_image);         switch (imagenumber){             case 0:                 if(sdkversion > 20)                     splashscreenbackground.setbackground(getdrawable(r.drawable.splash_screen_back));                 else                     splashscreenbackground.setbackgrounddrawable(getresources().getdrawable(r.drawable.splash_screen_back));                 return;             case 1:                 if(sdkversion > 20)                     splashscreenbackground.setbackground(getdrawable(r.drawable.buffon));                 else                     splashscreenbackground.setbackgrounddrawable(getresources().getdrawable(r.drawable.buffon));                 return;         }          mhandler.postdelayed(mendsplash, splash_duration_ms);     }      @override     public boolean ontouchevent(motionevent event) {         mendsplash.run();         return super.ontouchevent(event);     }      private runnable mendsplash = new runnable() {         public void run() {             if (!isfinishing()) {                 mhandler.removecallbacks(this);                  log.d(tag, "debugging before intent");                 startactivity(new intent(                         splashscreenactivity.this, mainactivity.class                 ));                 log.d(tag, "debugging after intent");                 finish();             }         };     };  }

and call in oncreate method:

mhandler.postdelayed(mendsplash, splash_duration_ms);

the problem activity doesn't chnage until press on screen.

another thing, class mainactivity charged , logs showed don't in screen !!! want know what's problem. thanks

you using return in switch instead of break, therefore code handler never reached.
