Android - dispatchTouchEvent gives me a StackOverflowError

Question

Here I have a ViewFlipper with a setOnTouchListener that works fine. Then I inflate ReLayNewsItem and later I add it to ViewFlipper.

Now I want WebView (web) to listen for touch events and pass them on to the ViewFlipper.

    final ViewFlipper VFnewsFeed = new ViewFlipper(this);

    VFnewsFeed.setOnTouchListener(new OnTouchListener(){
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (gestureDetectorLR.onTouchEvent(event)) { return true; }
            else { return true; }
        }});

    ///////////////////

    LayoutInflater inflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    RelativeLayout ReLayNewsItem = (RelativeLayout) inflater.inflate(R.layout.newsitem, null); 

    final WebView web = (WebView)ReLayNewsItem.findViewById(R.id.NewsItemWv);

    web.setOnTouchListener(new OnTouchListener(){
        @Override
        public boolean onTouch(View v, MotionEvent event) {

            VFnewsFeed.dispatchTouchEvent(event); /// ERROR HERE!
            return false;
        }});

Yet it gives me this -

07-14 21:12:43.600: E/AndroidRuntime(14048): FATAL EXCEPTION: main
07-14 21:12:43.600: E/AndroidRuntime(14048): java.lang.StackOverflowError

07-14 21:12:43.600: E/AndroidRuntime(14048):    at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:1320)
...

Any ideas? Thanks! ;)

"StackOverflow" errors are the best ;-) – Vinay W Aug 17 '12 at 08:30 — Vinay W, Aug 17 '12 at 08:30

If you return false it means that the event is unhandled.

Depending on your needs try to return true or VFnewsFeed.dispatchTouchEvent(event) in onTouch method instead of false.

didn't really get it. you think it should be done with onInterceptTouchEvent ? – Roger Travis Jul 15 '12 at 10:43
