Java 如何在WebView或VideoView中播放Youtube url

我只是想在WebView或VideoView中播放youtube url。假设。我已经学习了很多教程，但是我找不到一个方法

WebViewActivity

在onCreate（）中

而MyOwnWebViewClient是

public class MyOwnWebViewClient extends WebViewClient
    {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view , String url)
        {
            view.loadUrl(url);

            return true;
        }
    }

视频活动

在onCreate（）中

VideoViewTask.java在哪里

public class VideoViewTask extends AsyncTask<String, Void, String>
{
    ProgressDialog progressDialog;

    Context contexto;

    VideoView videoViewo;

    public VideoViewTask(Context context,VideoView videoView)
    {
        contexto = context;

        videoViewo = videoView;
    }

    @Override
    protected void onPreExecute()
    {
        super.onPreExecute();

        progressDialog = ProgressDialog.show(contexto, "", "Loading Video wait...", true);
    }
    @Override
    protected String doInBackground(String... arg0)
    {
        String videoUrl = "";
        try
        {
            String url =  "http://www.androidbegin.com/tutorial/AndroidCommercial.3gp";//"http://www.youtube.com/watch?v=1FJHYqE0RDg";
            videoUrl = getUrlVideoRTSP(url);
            //Log.e("Video url for playing=========>>>>>", videoUrl);
        }
        catch (Exception e)
        {
            //Log.e("Login Soap Calling in Exception", e.toString());
        }
        return videoUrl;
    }


    @Override
    protected void onPostExecute(String result)
    {
        super.onPostExecute(result);

        progressDialog.dismiss();

        videoViewo.setVideoURI(Uri.parse(result));
        MediaController mc = new MediaController(contexto);
        videoViewo.setMediaController(mc);
        videoViewo.requestFocus();
        videoViewo.start();          
        mc.show();


    }

    public static String getUrlVideoRTSP(String urlYoutube)
    {
        try
        {
            String gdy = "http://gdata.youtube.com/feeds/api/videos/";

            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            Document doc = documentBuilder.parse(connection.getInputStream());
            Element el = doc.getDocumentElement();
            NodeList list = el.getElementsByTagName("media:content");///media:content
            String cursor = urlYoutube;
            for (int i = 0; i < list.getLength(); i++)
            {
                Node node = list.item(i);
                if (node != null)

请按照下面的例子。我试过android开发者的视频。效果很好。只在应用程序中玩

 WebView wv=(WebView)findViewById(R.id.webview);
     wv.getSettings().setJavaScriptEnabled(true);
    //wv.getSettings().setPluginsEnabled(true);
    final String mimeType = "text/html";
    final String encoding = "UTF-8";
    String html = getHTML();
    wv.setWebChromeClient(new WebChromeClient() {
    });
    wv.loadDataWithBaseURL("", html, mimeType, encoding, "");

在oncreate中添加上述代码

public String getHTML() {
String html = "<iframe class=\"youtube-player\" style=\"border: 0; width: 100%; height: 95%; padding:0px; margin:0px\" id=\"ytplayer\" type=\"text/html\" src=\"http://www.youtube.com/embed/"
        + "s-4J7cijPAo"
        + "?fs=0\" frameborder=\"0\">\n"
        + "</iframe>\n";
return html;

公共字符串getHTML（）{
字符串html=“\n”
+“\n”；
返回html；

插入您的youtube视频id，如上所述。

您是否尝试在不使用youtube API的情况下使用youtube android apiNo。我想在不使用youtube API的情况下播放该视频。@Nepster使用intentPlease Reference和在WebView中加载youtube视频会发生什么？Rambau我没有安装youtube player，因此它会转到catch block。哪一个所以不要播放itRamBabu youtube在我们地区是被禁止的。它显示图像，但我无法播放。当我播放它时，它说“视频包含UMG的内容。它被限制在某些网站上播放。”您是否尝试使用上述确切代码。我的应用程序中也有相同的视频。它说网站无法访问。禁止在您的区域内观看

public void watchYoutubeVideo(String id)
    {
        try
        {
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("vnd.youtube:" + id));

            startActivity(intent);

        }
        catch (ActivityNotFoundException ex)
        {
            Intent intent = new Intent(Intent.ACTION_VIEW,
                    Uri.parse("http://www.youtube.com/watch?v=" + id));
            startActivity(intent);
        }
    }

 WebView wv=(WebView)findViewById(R.id.webview);
     wv.getSettings().setJavaScriptEnabled(true);
    //wv.getSettings().setPluginsEnabled(true);
    final String mimeType = "text/html";
    final String encoding = "UTF-8";
    String html = getHTML();
    wv.setWebChromeClient(new WebChromeClient() {
    });
    wv.loadDataWithBaseURL("", html, mimeType, encoding, "");

public String getHTML() {
String html = "<iframe class=\"youtube-player\" style=\"border: 0; width: 100%; height: 95%; padding:0px; margin:0px\" id=\"ytplayer\" type=\"text/html\" src=\"http://www.youtube.com/embed/"
        + "s-4J7cijPAo"
        + "?fs=0\" frameborder=\"0\">\n"
        + "</iframe>\n";
return html;
