我正在尝试在SurfaceTexture上绘制WebView,以便我可以在OpenGL中渲染它.

到目前为止,我成功地在WebView中以标准方式播放了youtube视频:

  ...
  webView.getSettings().setJavaScriptEnabled(true);

  if (Build.VERSION.SDK_INT < 8) 
  {
     webView.getSettings().setPluginsEnabled(true);
  } 
  else 
  {
     webView.getSettings().setPluginState(WebSettings.PluginState.ON);
  }
  webView.setWebChromeClient(new WebChromeClient() { });
  webView.setWebViewClient(new WebViewClient());
  ...

还打开了硬件加速:

 <application
        android:hardwareAccelerated="true"
 ...

我还基于本教程在OpenGL中成功渲染了WebView(除了播放视频):http://anuraagsridhar.wordpress.com/2013/03/13/rendering-an-android-webview-or-for-that-物质-任何-机器人-视图-直接到的OpenGL /

WebView的附加初始化(因此它始终是"纵向"并适合纹理):

 Point p = new Point();
 activity.getWindow().getWindowManager().getDefaultDisplay().getSize(p);
 webView.setLayoutParams(new ViewGroup.LayoutParams(p.x, p.y));
 surfaceTexture.setDefaultBufferSize(p.x, p.y);

Overriden WebView的onDraw方法:

@Override
public void onDraw(Canvas c)
{
   try
   {
      Point p = new Point();
      activity.getWindow().getWindowManager().getDefaultDisplay().getSize(p);
      Canvas canvas = surfaceTexture.lockCanvas(new Rect(0,0,p.x,p.y));
      canvas.save();
      canvas.translate(-scrollL, -scrollT);
      super.onDraw(canvas);
      canvas.restore();
      surfaceTexture.unlockCanvasAndPost(canvas);
   }
   catch (Surface.OutOfResourcesException e)
   {
      throw new RuntimeException(e);
   }
} …
