Android Webview应用程序不会让video播放器全屏显示
您好，我为我的video网站创build了一个webview应用程序。 该网站的devise是一个混合加载移动用户。 只有与移动设备兼容的video才能加载到混合动力车上。 玩家来自VK，dailymotion，youtube，quicktime。 video只能播放sdk 11和更高，但是当我点击播放button去全屏，它只停止播放video，而不会启动到全屏模式。 我尽可能地包含尽可能多的代码，希望有人能帮助我。 我已经把这个search引擎无事化了。 任何帮助将不胜感激。
（Webviewactivity.java）
public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); getWindow().requestFeature(Window.FEATURE_PROGRESS); setContentView(R.layout.main); parentView = (RelativeLayout) findViewById(R.id.parent_rl); webviewProgress = (ProgressBar) findViewById(R.id.webview_progress); webview = (WebView) findViewById(R.id.webview); webview.getSettings().setJavaScriptEnabled(true); webview.getSettings().setBuiltInZoomControls(true); webview.getSettings().setAllowFileAccess(true); webview.setWebViewClient(new MyWebViewClient()); webview.getSettings().setPluginState(WebSettings.PluginState.ON); webview.loadUrl(URL); webviewProgress.setProgress(0); webview.setWebChromeClient(new MyWebChromeClient()); webview.setDownloadListener(new DownloadListener() { public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimetype, long contentLength) { mProgressDialog = new ProgressDialog(WebViewActivity.this); mProgressDialog.setMessage("Downloading..."); mProgressDialog.setIndeterminate(false); mProgressDialog.setMax(100); mProgressDialog .setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); DownloadFile downloadFile = new DownloadFile(); downloadFile.execute(url); } }); initSlider(); initAdmob(); } /** * When when file was chosen */ @Override protected void onActivityResult(int requestCode, int resultCode, Intent intent) { if (requestCode == FILECHOOSER_RESULTCODE) { if (null == mUploadMessage) return; Uri result = intent == null || resultCode != RESULT_OK ? null : intent.getData(); mUploadMessage.onReceiveValue(result); mUploadMessage = null; （main.xml中）

您需要实现showCustomView ＆ hideCustomView方法，您的AndroidManifest文件中还需要android:hardwareAccelerated="true" 。 我在这里发布我的示例项目。 我所做的是在main.xml中保留一个Framelayout（customContainer），并在showCustomView中添加接收的视图，并在onHide中移除它。 也相应地隐藏/显示webview。 下面的代码在设备上完美工作。
AndroidManifest.xml中
