Question

最近人们的应用开始出现问题。在webview中滚动页面时强制关闭。下面是他们发给我的堆栈跟踪。 请注意，空指针异常发生在系统提供的WebView代码中。任何人都知道可能出错了什么？如果需要，我会附上我的应用程序的任何部分的代码，这些代码可能与WebView代码中的失败有关。

感谢您的任何提示。

编辑：

我在页面加载时禁用了触摸侦听器，并在页面完成时启用它。

webView = new WebView(this);
        webView.addJavascriptInterface(this, "DragonLords");
        webView.setWebViewClient(webViewClient);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.setScrollBarStyle(1);
        webView.loadData("<body style='background-color: black'>&nbsp</body>", "text/html", "UTF-8");
        webView.setOnTouchListener(this.disablingTouchListener);


private final OnTouchListener disablingTouchListener = new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            return webviewDisabled;
        }
    };

空指针异常，触摸事件的Webview
