android - onClickListener not letting onFling trigger -

i have both onclicklistener , onfling (using gesturedetector).

if click on button onclicklistener fires.

if fling on body of screen onfling fires.

however if start fling button, neither fire.

layout follows:

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"               xmlns:tools="http://schemas.android.com/tools"               android:layout_width="match_parent"               android:layout_height="match_parent">     <button             android:id="@+id/mybutton"             android:layout_margin="50dp"             android:layout_height="100dp"             android:layout_width="match_parent"             android:text="button"/> </linearlayout> 

and code looks like:

public class mylayout extends activity implements gesturedetector.ongesturelistener {     private gesturedetector gdetector;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.mylayout);          gdetector = new gesturedetector(getbasecontext(), this);         findviewbyid(r.id.mybutton).setonclicklistener(button_onclicklistener);     }      final view.onclicklistener button_onclicklistener = new view.onclicklistener() {         public void onclick(final view buttonview) {             toast.maketext(getapplicationcontext(), "button pressed", toast.length_long).show();         }     };      @override     public boolean ondown(motionevent motionevent) {         return true;     }      @override     public void onshowpress(motionevent motionevent) {     }      @override     public boolean onsingletapup(motionevent motionevent) {         return false;     }      @override     public boolean onscroll(motionevent motionevent, motionevent motionevent2, float v, float v2) {         return false;     }      @override     public void onlongpress(motionevent motionevent) {     }      @override     public boolean onfling(motionevent start, motionevent finish, float v, float v2) {         if (start.getrawy() < finish.getrawy()) {             toast.maketext(getapplicationcontext(), "fling detected", toast.length_long).show();         }         return false;     }      @override     public boolean ontouchevent(motionevent me) {         log.i("touch", "ontouchevent");         return gdetector.ontouchevent(me);     } } 

how can onfling run first?

i have looked @ other posts (e.g. onclick blocking onfling) not found suitable answer.

you should try using onintercepttouchevent() (or, maybe dispatchtouchevent(), @ point i'm not sure suit better) of button's parent (or higher in hierarchy) decide whether route touch button or gesture detector.

if motionevent's coordinates belong button's rect , action_down followed action_up shortly, it's click , should routed button, if receive action_move , movement continues extent know it's swipe - should handled gesture detector.
