我在 webview 中加载了其他系统给出的 url。但它不显示所有内容，它在页面中留下一个空白窗口。我检查源代码，它有一个框架集标签和一些 iframe 标签。att src 是正确的。为什么它不能从 src 加载内容？webchromeclient 是否支持 php iframe 标签？

<frameset id ="dispframeset" rows="*,6%" frameborder="NO" border="0" framespacing="0">
    <frame id="articleFrame" src="/csp/kbs/showKngContent.action?inRecycle=&kngTblFlag=0&kngId=20130228152142812001&dispId=&articleFlag=true&relativeKngFlag=true&buttonFlag=true&coluKngType=2&kngPath=&coluKngName=&kngPointId=&kngPointName=&kngPointPath=&showType=1&backBtnFlag=&dispTmpPreview=&channelId=0&curChannelId=&currentChannelId=&isBackOrGoahead=&clickingLogFlag=" name="articleFrame" scrolling="no" resize/>
    <frame id="articleButtonFrame" src="/csp/kbs/showKngButton.action?kngId=20130228152142812001&dispId=&kngTblFlag=0&buttonFlag=true&showType=1&channelId=0" name="articleButtonFrame" scrolling="auto" resize/>
</frameset>

顺便说一句，网络应用在 IE 浏览器中运行良好，但在 chrome 中很糟糕。

提前考虑。

就我而言，WebChromeClient 支持 iframe 标签。在我的情况下，我通过以下方式将 iframe 标签提供给 webview。

<iframe width=\"480\" height=\"270\" src=\"http://staging.snagfilms.com/modules/html5player.jsp?filmId=ed9195a0-a748-11e0-a92a-0026bb61d036&w=500\" frameborder=\"0\" allowfullscreen></iframe>

上面是 iframe 标签，我是从服务器获取的

myWebView = (CustomFacedWebView) findViewById(R.id.web_wrap_browser);
myWebView.getSettings().setPluginsEnabled(true);
        myWebView.getSettings().setJavaScriptEnabled(true);
        myWebView.getSettings().setPluginState(PluginState.ON);
        chromeClient = new MyChromeClient();
        myWebView.setWebChromeClient(chromeClient);
myWebView.loadUrl(URL)
webRoot = (ViewGroup) findViewById(R.id.web_root_view);
        systemRoot = (ViewGroup) webRoot.getParent();



private final class MyChromeClient extends WebChromeClient implements OnCompletionListener, OnErrorListener {
        CustomViewCallback fullscreenCallback;
        VideoView htmlVideoView;

        @Override
        public void onShowCustomView(final View view, final CustomViewCallback callback) {
            super.onShowCustomView(view, callback);

            fullscreenCallback = callback;
            systemRoot.removeAllViews();
            setContentView(view);
            fullScreen = true;
            ............    

        }


        @TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
        @Override
        public void onShowCustomView(final View view, final int requestedOrientation,
                final CustomViewCallback callback) {
            super.onShowCustomView(view, requestedOrientation, callback);

            systemRoot.removeAllViews();
            setContentView(view);
            setRequestedOrientation(requestedOrientation);
            fullscreenCallback = callback;

        }

        @Override
        public void onHideCustomView() {
            super.onHideCustomView();
            if(htmlVideoView != null) {
                htmlVideoView.stopPlayback();
            }
            if(webRoot != null) {
                systemRoot.removeAllViews();
                setContentView(webRoot);
            }
            try{
            if(fullscreenCallback != null)
                fullscreenCallback.onCustomViewHidden();
            } catch(Exception e) {
                e.printStackTrace();
            }
            fullScreen = false;

        }

        @Override
        public boolean onError(MediaPlayer mp, int what, int extra) {
            onHideCustomView();
            return false;
        }

        @Override
        public void onCompletion(MediaPlayer mp) {
            onHideCustomView();
        }
    }
