Question

我正在编写一个使用WebView从youtube播放视频的应用程序。播放没有问题，但视频有自己的标题，对我来说不是那么有用。如何删除它？

Answer 1

你可以有一个javascript文件来完成这个动作，然后在onPageFinished reference

上使用loadUrl方法注入它

我有自定义iftube视频iframe的完整解决方案

WebView webView;
    ProgressBar progressBar;
    ImageView back_btn;

    String video_url = "KK9bwTlAvgo", html = "";

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.full_screen_youtube_video_screen);

        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

        back_btn = (ImageView) findViewById(R.id.full_videoview_btn);
            back_btn.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    webView.loadData("", "text/html", "UTF-8");
                    finish();
                }
            });

            webView = (WebView) findViewById(R.id.webView);
               progressBar = (ProgressBar) findViewById(R.id.progressBar);

            if (video_url.equalsIgnoreCase("")) {
                finish();
                return;
            }

            WebSettings ws = webView.getSettings();
            ws.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.SINGLE_COLUMN);
            ws.setPluginState(WebSettings.PluginState.ON);
            ws.setJavaScriptEnabled(true);
            webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
            webView.reload();

            if (networkUtil.isConnectingToInternet(Act_VideoPlayer.this)) {
                html = getHTML(video_url);
            } else {
                html = "" + getResources().getString(R.string.The_internet_connection_appears_to_be_offline);
                CustomToast.animRedTextMethod(Act_VideoPlayer.this, getResources().getString(R.string.The_internet_connection_appears_to_be_offline));
            }

            webView.loadData(html, "text/html", "UTF-8");

            WebClientClass webViewClient = new WebClientClass(progressBar);
            webView.setWebViewClient(webViewClient);
            WebChromeClient webChromeClient = new WebChromeClient();
            webView.setWebChromeClient(webChromeClient);
    }




    @Override
    protected void onDestroy() {
        super.onDestroy();
        try {
            webView.loadData("", "text/html", "UTF-8");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onBackPressed() {
        super.onBackPressed();
        try {
            webView.loadData("", "text/html", "UTF-8");
            finish();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }


    public class WebClientClass extends WebViewClient {
        ProgressBar ProgressBar = null;

        WebClientClass(ProgressBar progressBar) {
            ProgressBar = progressBar;
        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
            ProgressBar.setVisibility(View.VISIBLE);
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);
            ProgressBar.setVisibility(View.GONE);
        }

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            LogShowHide.LogShowHideMethod("webview-click :", "" + url.toString());
            view.loadUrl(getHTML(video_url));
            return true;
        }
    }

    public String getHTML(String videoId) {
        String html = "<iframe class=\"youtube-player\" " + "style=\"border: 0; width: 100%; height: 96%;"
                + "padding:0px; margin:0px\" " + "id=\"ytplayer\" type=\"text/html\" "
                + "src=\"http://www.youtube.com/embed/" + videoId
                + "?&theme=dark&autohide=2&modestbranding=1&showinfo=0&autoplay=1\fs=0\" frameborder=\"0\" "
                + "allowfullscreen autobuffer " + "controls onclick=\"this.play()\">\n" + "</iframe>\n";
        LogShowHide.LogShowHideMethod("video-id from html url= ", "" + html);
        return html;
    }
