android - Intercepted ScrollView interfering with child onClick events -

i've layout in custom scrollview has horizontal viewpager , textview below it. onclick of textview stops working if use interpretedscrollview instead of scrollview. need interpretedscrollview allow horizontal scroll in viewpager.

<com.package.interceptedscrollview    <viewpager     // scrolls horizontally interceptedscrollview      />    ...    <textview       // try scrolling vertically touching imageview , doesn't scroll       onclick="something"/> </com.package.interceptedscrollview> 

and custom scrollview

public class interceptedscrollview extends scrollview {     gesturedetector mgesturedetector;      private class verticalscrolldetector extends simpleongesturelistener {         @override         public boolean onscroll(motionevent e1, motionevent e2, float x, float y) {             if (math.abs(y) > math.abs(x)) {                 // scrolling in y direction essentially. should scroll                 // vertically.                 return true;             }             // not of scroll in y. don't scroll.             return false;         }     }      public interceptedscrollview(context ctx, attributeset as) {         super(ctx, as);         mgesturedetector = new gesturedetector(ctx, new verticalscrolldetector());         setfadingedgelength(0);     }      @override     public boolean onintercepttouchevent(motionevent event) {         return super.onintercepttouchevent(event) && mgesturedetector.ontouchevent(event);     } } 

why interceptedscrollview eating onclick of textview? how fix it?

my custom scrollview use totalsize of xscroll , yscroll. record current xpoint , ypoint,when click down. calculate when moving .

public class pagescrollview extends scrollview {      private float xdistance, ydistance, lastx, lasty;  public pagescrollview(context context, attributeset attrs) {     super(context, attrs); }  @override public boolean onintercepttouchevent(motionevent ev) {      switch (ev.getaction()) {         case motionevent.action_down:             xdistance = ydistance = 0f;             lastx = ev.getx();             lasty = ev.gety();             break;         case motionevent.action_move:             final float curx = ev.getx();             final float cury = ev.gety();             xdistance += math.abs(curx - lastx);             ydistance += math.abs(cury - lasty);             lastx = curx;             lasty = cury;             if(xdistance > ydistance)                 return false;     }      return super.onintercepttouchevent(ev); } }
