android - swipe between activities,swipe from one activity to another -

i trying swipe activity failed so. below code doing nothing, not giving error. don't know do.

    final view lay_first=(view) findviewbyid(r.id.lay_first);      lay_first.setontouchlistener(new onswipetouchlistener(){         @override         public boolean onswipeleft() {             intent intent=new intent(slidewindow.this,mainactivity.class);             startactivity(intent);             overridependingtransition(r.anim.right_to_left, r.anim.rl2);                 return true;         }         @override         public boolean onswiperight() {         intent intent=new intent(slidewindow.this,mainactivity.class);         startactivity(intent);         overridependingtransition(r.anim.right_to_left, r.anim.rl2);             return true;         }         @override         public boolean onswipebottom() {             super.onswipebottom();             return true;         }         @override         public boolean onswipetop() {             super.onswipetop();             return true;         } }); } public class onswipetouchlistener implements ontouchlistener{             @suppresswarnings("deprecation")     gesturedetector gesturedetector=new gesturedetector(new gesturelistener());     @override     public boolean ontouch(view v, motionevent event) {                  if(gesturedetector.ontouchevent(event))         {             return true;         }         return false;     } private final class gesturelistener extends simpleongesturelistener{      private static final int swipe_threshold = 100;          private static final int swipe_velocity_threshold = 100;            @override         public boolean ondown(motionevent e) {             return super.ondown(e);         }           @override         public boolean onfling(motionevent e1, motionevent e2,                 float velocityx, float velocityy) {         boolean result=false;          try         {             float diffy=e2.gety()-e1.gety();             float diffx=e2.getx()-e1.getx();              if(math.abs(diffx)>math.abs(diffy))             {       if(math.abs(diffx)>swipe_threshold && math.abs(velocityx)>swipe_velocity_threshold)                 {                     if(diffx>0)                     {                         result=onswiperight();                     }                     else                     {                         result=onswipeleft();                     }                 }             }             else             {             if(math.abs(diffy)>swipe_threshold && math.abs(velocityy)>swipe_velocity_threshold)                 {                     if(diffy>0)                     {                         result=onswipebottom();                     }                     else                     {                         result=onswipetop();                     }       }             }         }catch(exception e)         {             e.printstacktrace();         }             return result;         }   }        public boolean onswiperight()          {     return false;           }          public boolean onswipeleft()          {     return false;                          }          public boolean onswipebottom() {              return false;      }          public boolean onswipetop() {              return false;      } }} 

but when doing slide on touchevent running.but when adding gestures not,as gesturedetector class depriciated reason program not running.
