java - 在 webview 中显示 youtube 视频显示空白页面；点击播放按钮时屏幕将变为空白

Question

我正在从我的服务器获取 youtube id 并将其制作为 youtube 嵌入 url，之后我在 ListView 中显示该 youtube url，同时单击列表项，youtube 视频必须在 webview 中播放，这是我的要求，我尝试了所有方法它对我不起作用，它显示空白页

像这样我从我的服务器获取并制作为 youtube url

app1.setUrlWiki("http://www.youtube.com/embed/"+json.getString("youtube_url")+"?fs=0");

这是我的mainactivity.java

lv2 =(ListView)findViewById(R.id.listV_main);   
        lv2.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> a, View v, int position, long id) { 
                Object o = lv2.getItemAtPosition(position);
                Application1 obj_itemDetails = (Application1)o;


                Intent intent1=new Intent(PoojaVideos.this,WebViewActivity.class);
                //Log.d("test","strContactList: "+strContactList);
                //intent1.putExtra("firstKeyName", Uri.parse(((Application1) o).getUrlWiki()));
                String link = Uri.parse(((Application1) o).getUrlWiki()).toString();
                intent1.putExtra("firstKeyName", link);
                startActivity(intent1);


            } 
        });

从那里我根据点击将 url 发送到 webview Activity

webviewactivity.java 音频单独出现，但视频不显示

 public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.webview);
             //wv = (WebView) findViewById(R.id.webView);

              mContentView = (FrameLayout) findViewById(R.id.main_content);
             wv = (WebView) findViewById(R.id.webView);
             mCustomViewContainer = (FrameLayout) findViewById(R.id.fullscreen_custom_content);

            wv.getSettings().setJavaScriptEnabled(true);
            wv.getSettings().setPluginsEnabled(true);
            wv.setWebChromeClient(new WebChromeClient() {
            });
            final String mimeType = "text/html";
            final String encoding = "UTF-8";
            String html = getHTML();
            System.out.println(".................."+html);
            wv.loadDataWithBaseURL("", html, mimeType, encoding, "");

        }

        public String getHTML() {

            Intent intent1= getIntent(); // gets the previously created intent
        String firstKeyName1 = intent1.getStringExtra("firstKeyName");
             Toast.makeText(this, firstKeyName1, 1000).show();
             System.out.println("kkkkk."+firstKeyName1);
             String html = "<iframe class=\"youtube-player\" style=\"border: 0; width: 100%; height: 95%; padding:0px; margin:0px\" id=\"ytplayer\" type=\"text/html\"  src="firstKeyName1" frameborder=\"0\">\n"
                        + "</iframe>\n";

                return html;

        }

WebView .xml

<WebView
    android:id="@+id/webView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" />

点击播放按钮时，音频正在运行，但视频不显示，显示黑屏。**

您必须以这种方式在 html 字符串中设置 url:

String html = "<iframe class=\"youtube-player\" style=\"border: 0; width: 100%; height: 95%; padding:0px; margin:0px\" id=\"ytplayer\" type=\"text/html\" src='"+firstKeyName1 +"' frameborder=\"0\">\n"
                        + "</iframe>\n";

现在您可以轻松地在该屏幕中看到 YouTube 视频。
