Add gesture listener to child view without hiding parent's touch event

I want to have an overlay view to receive gesture events but still keep receiving onTouch event of parent(below) view. However, The gesture in child view seems hide parent onTouch event.

Layout

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ParentView android:background="#FFFFFF" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ChildView android:background="#FF4433" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="200dp" android:layout_marginTop="100dp"> </ChildView> </ParentView> </LinearLayout> 

Parent View:

public class ParentView extends FrameLayout implements View.OnTouchListener { public ParentView(Context context, AttributeSet attrs) { super(context, attrs); setOnTouchListener(this); } @Override public boolean onTouch(View view, MotionEvent event) { Logger.write("Parent is touching"); return false; } } 

Client View:

public class ChildView extends FrameLayout implements View.OnTouchListener { private GestureDetector myGestureDetector; private boolean isTapping; public ChildView(Context context, AttributeSet attrs) { super(context, attrs); myGestureDetector=new GestureDetector(context, new MyGestureDetector()); setOnTouchListener(this); } @Override public boolean onTouch(View view, MotionEvent event) { return myGestureDetector.onTouchEvent(event); } class MyGestureDetector extends GestureDetector.SimpleOnGestureListener { @Override public boolean onDown(MotionEvent e) { return true; } @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { try { final ViewConfiguration vc = ViewConfiguration.get(getContext()); final int swipeMinDistance = vc.getScaledPagingTouchSlop(); final int swipeMaxOffPath = vc.getScaledTouchSlop(); final int swipeThresholdVelocity = vc.getScaledMinimumFlingVelocity() / 2; if (Math.abs(e1.getY() - e2.getY()) > swipeMaxOffPath) { return false; } // right to left swipe if (e2.getX() - e1.getX() > swipeMinDistance && Math.abs(velocityX) > swipeThresholdVelocity) { Logger.write("Swipe!!!!!!!!!!!!!!!!!!!!!!!"); } } catch (Exception e) { // nothing } return false; } } }
