Question

我在Html开发了一个媒体播放器。现在我的工作是在来自streaming Url活动的Html编码媒体播放器中播放Android。所以我需要将网址从android activity传递到Html媒体播放器文件，然后播放。我搜索了很多但没有找到任何好的解决方案。请指教我。感谢

Java代码

setContentView(R.layout.main);
//      String LocalFile = "file:///android_asset/android.html";

        WebView webView = (WebView) findViewById(R.id.webView1);
        String html = "<embed src=\"file:///android_asset/"
                + "android.html"
                + " \"play=\"true\" loop=\"true\" width=\"100%\" height=\"100%\"> <embed>";
        webView.getSettings().setPluginState(WebSettings.PluginState.OFF);
        webView.getSettings().setPluginsEnabled(true);
        webView.getSettings().setAllowFileAccess(true);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadDataWithBaseURL("file:///android_asset/", html,
                "text/html", "utf-8", null);
        String str = "rtmp://23.21.155.146:554/9016012507701502509011502505116016019xm150.sdp";
        webView.loadUrl("javascript:passWebUrl('" + str + "')");

要将变量的值从java类传递到html页面中的javascript函数，必须使用此代码。试试这个：

String str = "variable_value";
webView.loadUrl("javascript:functionName('"+ str +"')");

编辑： -

 function passWebUrl(url)
 {
        alert(url);
 }

与Html和Android接口
