L'app Android Webview non consente al lettore video di andare a schermo intero

Question

Ciao Ho creato un'app Webview per il mio sito di video. Il design del sito è un ibrido che carica per gli utenti mobili. Solo i video compatibili con i dispositivi mobili vengono caricati sull'ibrido. I giocatori provengono da Vk, dailymotion, youtube, quicktime. I video vengono riprodotti solo su sdk 11 e versioni successive, ma quando faccio clic sul pulsante del lettore per andare a schermo intero, interrompe solo la riproduzione del video senza avviarlo mai in modalità a schermo intero. Sto includendo tutto il codice che posso, nella speranza che qualcuno possa aiutarmi. L'ho interrogato a morte senza alcun progresso. Qualsiasi aiuto sarebbe molto apprezzato.

(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;

È necessario implementare showCustomView & hideCustomView metodo WebChromeClient , inoltre è necessario android:hardwareAccelerated="true" i n il tuo file AndroidManifest. Sto postando il mio progetto di esempio qui. Quello che ho fatto è conservato un Framelayout (customContainer) nel mio main.xml, e aggiungendo la vista ricevuta in showCustomView qui, e rimuovendola in onHide. Anche nascondendo/mostrando di conseguenza la webview. Sotto il codice funziona perfettamente sul dispositivo.
