                    return super.shouldOverrideUrlLoading(view, url);

            });
}

You may use the below listed code:

public class YouTube extends Activity{

  public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
      WebView myWebView;
      myWebView = (WebView) findViewById( R.id.web);
      myWebView.setWebViewClient(new MyWebViewClient());
  String pre="<iframe class=youtube-player type=text/html width=";
  String height=" height=";
  String suffix=" src=http://www.youtube.com/embed/**xxxxxxxxxxx**?autoplay=1 frameborder=0>"; // replace xxxxxxxxxxx with the specific embed id of your video
      String playVideo=pre+260+height+150+suffix;
      myWebView.getSettings().setPluginsEnabled(true);
      myWebView.getSettings().setJavaScriptEnabled(true);
  myWebView.loadData(playVideo,"text/html","UTF-8");
}
// override default behaviour of the browser

private class MyWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }


        ProgressDialog dialog = ProgressDialog.show(getApplicationContext(), "", 
                "Loading. Please wait...", true);
        @Override
           public void onPageFinished(WebView view, String url) {
            dialog.dismiss();
          }


    } }
