Android的 - dispatchTouchEvent给我的StackOverflowError

问题描述

在这里，我有工作正常一个setOnTouchListener一个ViewFlipper。然后我膨胀ReLayNewsItem，后来我把它添加到ViewFlipper。

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

现在我想的WebView（网络）侦听触摸事件，并将它们传递到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;
        }});

然而，它给了我这一点 -

Yet it gives me this -

...

任何想法？谢谢！ ;）

Any ideas? Thanks! ;)

推荐答案

如果您返回假这意味着该事件的未处理。

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

根据您的需要尝试返回真正或 VFnewsFeed.dispatchTouchEvent（事件）在 onTouch 方法，而不是假。

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