After all i found solution to my problem is to override the ontouch event of horizontal scrollview as like ...
public class CustomScrollView extends HorizontalScrollView {
public CustomScrollView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public boolean onTouchEvent(MotionEvent ev) {
return true;
}
public boolean onInterceptTouchEvent(MotionEvent ev) {
return false;
}
}
