java - Clickable View Pager in Android -

i want set on click event in view pager. viewpageradapter looks this-

public class viewpageradapder extends pageradapter {      activity activity;     string image[];      public viewpageradapder(activity act, string[] imgarra) {         image = imgarra;         activity = act;     }      public int getcount() {         return image.length;     }      public object instantiateitem(view collection, final int position) {         imageview view = new imageview(activity);          view.setlayoutparams(new viewgroup.layoutparams(viewgroup.layoutparams.match_parent,                                     viewgroup.layoutparams.match_parent));         new imagedownloadertask(view).execute(image[position]);         view.setscaletype(imageview.scaletype.center_crop);         view.setadjustviewbounds(true);         ((viewpager) collection).addview(view, 0);      //  view.setbackgroundresource(imagearray[position]);          return view;     }      @override     public void destroyitem(view arg0, int arg1, object arg2) {         ((viewpager) arg0).removeview((view) arg2);     }      @override     public boolean isviewfromobject(view arg0, object arg1) {         return arg0 == ((view) arg1);     }      @override     public parcelable savestate() {         return null;     } } 

and setting onclicklistener in main activity

 mypager = (viewpager) view.findviewbyid(r.id.viewpager);          mypager.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                 toast.maketext(getactivity(), "ckecking success",                         toast.length_short).show();             } } 

my viewpager works fine. tried implement onclicklistener in both main activity in viewpageradapter class. not work either way.

use class view pager click.

clickableviewpager.java

public class clickableviewpager extends viewpager {     private onitemclicklistener monitemclicklistener;      public clickableviewpager(context context) {         super(context);         setup();     }      public clickableviewpager(context context, attributeset attrs) {         super(context, attrs);         setup();     }      private void setup() {         final gesturedetector tapgesturedetector = new    gesturedetector(getcontext(), new tapgesturelistener());          setontouchlistener(new ontouchlistener() {             @override             public boolean ontouch(view v, motionevent event) {                 tapgesturedetector.ontouchevent(event);                 return false;             }         });     }      public void setonitemclicklistener(onitemclicklistener onitemclicklistener) {         monitemclicklistener = onitemclicklistener;     }      public interface onitemclicklistener {         void onitemclick(int position);     }      private class tapgesturelistener extends gesturedetector.simpleongesturelistener {          @override         public boolean onsingletapconfirmed(motionevent e) {             if(monitemclicklistener != null) {                 monitemclicklistener.onitemclick(getcurrentitem());             }             return true;         }     } } 

click event

clickablepager.setonitemclicklistener(new clickableviewpager.onitemclicklistener() {             @override             public void onitemclick(int position) {     }  });
