android - How can I disable a thread with an onClickListener? -

i working on splash screen test , implemented click listener layout can skipped clicking on screen. problem intent called twice, because loading thread not interrupted when screen clicked. doing wrong , how avoid error?

public class splashscreen extends activity {     final thread loading = new thread();  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setrequestedorientation(activityinfo.screen_orientation_portrait);     setcontentview(r.layout.splashscreen);     imageview splashscreenview = (imageview) findviewbyid(r.id.splashscreenanimation);     splashscreenview.setbackgroundresource(r.drawable.flashscreenanimation);     animationdrawable splashscreenanimation = (animationdrawable) splashscreenview.getbackground();     splashscreenanimation.start();     relativelayout ontouchskipscreen = (relativelayout)findviewbyid(r.id.splashscreenview);     ontouchskipscreen.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view view) {             loading.interrupt();             loading.isinterrupted();             intent splashscreen = new intent(splashscreen.this, homescreen.class);             startactivity(splashscreen);             overridependingtransition(r.anim.fade_in, r.anim.fade_out);             finish();         }     });     thread loading = new thread() {         public void run() {             try {                 sleep(2573);                 intent splashscreen = new intent(splashscreen.this, homescreen.class);                 startactivity(splashscreen);                 overridependingtransition(r.anim.fade_in, r.anim.fade_out);             } catch (exception e) {                 e.printstacktrace();             } {                 finish();             }         }     };     loading.start(); } } 

go it

public class splashscreen extends activity {     thread loading ;     boolean flag = true;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setrequestedorientation(activityinfo.screen_orientation_portrait);         setcontentview(r.layout.splashscreen);         imageview splashscreenview = (imageview) findviewbyid(r.id.splashscreenanimation);         splashscreenview.setbackgroundresource(r.drawable.bontactbook);         animationdrawable splashscreenanimation = (animationdrawable) splashscreenview.getbackground();         splashscreenanimation.start();         relativelayout ontouchskipscreen = (relativelayout) findviewbyid(r.id.flashscreenanimation);         ontouchskipscreen.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view view) {                 flag = false;                 intent splashscreen = new intent(splashscreen.this, homescreen.class);                 startactivity(splashscreen);                 finish();             }         });         thread loading = new thread() {             public void run() {                 try {                     sleep(5000);                     if (flag) {                         intent splashscreen = new intent(splashscreen.this, homescreen.class);                         startactivity(splashscreen);                         overridependingtransition(r.anim.fade_in, r.anim.fade_out);                     }                 } catch (exception e) {                     e.printstacktrace();                 } {                     finish();                 }             }         };         loading.start();     } }
