java - Android如何在Android iframe Webview中传递URL？

android如何在android中传递url？
我正在尝试从服务器动态传递url，所以我要做的是

if(ResponseProduct.video!=null) {

                            String html = "<iframe width=\"450\" height=\"260\" src=\""+ResponseProduct.video+"\" ></iframe>";
                            WebView webView = (WebView) view.findViewById(R.id.video);
                            webView.setVisibility(View.VISIBLE);
                            webView.getSettings().setPluginState(WebSettings.PluginState.ON);
                            webView.getSettings().setPluginState(WebSettings.PluginState.ON_DEMAND);
                            webView.getSettings().setJavaScriptEnabled(true);
                            webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
                            webView.getSettings().setSupportMultipleWindows(true);
                            webView.setWebChromeClient(new WebChromeClient());
                            webView.setHorizontalScrollBarEnabled(false);
                            webView.loadData(html, "text/html; video/mpeg", "UTF-8");

                        }

最佳答案

您需要将Stringurl路径放入src中，例如：

 String videoPath="http://api.thingspeak.com/channels/31592/charts/1?width=450&height=260&results=60&dynamic=true\\";

 String html = "<iframe width=\"450\" height=\"260\" style=\"border: 1px solid #cccccc;\" src=\""+videoPath+" ></iframe>";

如果videourl为空或无效，则页面未加载，则需要隐藏webview
代码如下：

private boolean isValidUrl(String url) {
      Pattern p = Patterns.WEB_URL;
      Matcher m = p.matcher(url.toLowerCase());
      if(m.matches())
         return true;
      else
        return false;
}

然后加载到webView

 webview.getSettings().setJavaScriptEnabled(true);
if(videoPath!=null && isValidUrl(videoPath)
{
mWebView.setVisibility(View.VISIBLE);
webview.loadData(html, "text/html", null);
    }

else
webview.setVisibility(View.GONE);
