如何获得HTML5视频的URI HTML5VFullScreen $ SurfaceVideoView在Android 4.0的？ [英] How to get HTML5 video URI in HTML5VFullScreen$SurfaceVideoView in Android 4.0?

问题描述

我想，当用户点击了视频控制栏上的全屏按钮来获得一个HTML5视频的URI。据<一href="http://grep$c$c.com/file/repository.grep$c$c.com/java/ext/com.google.android/android/4.0.1_r1/android/webkit/HTML5VideoFullScreen.java">this,在Android 4.0的HTML5视频的看法是一个SurfaceView，而不是VideoView。

有人能告诉我怎么走SurfaceVideoView的URI？这是我的code。非常感谢。

  webView.setWebChromeClient（新WebChromeClient（）{
  @覆盖
  公共无效onShowCustomView（查看视图，CustomViewCallback回调）{
    super.onShowCustomView（查看，回调）;
    如果（查看的instanceof的FrameLayout）{
      最后的FrameLayout帧=（的FrameLayout）视图;
      如果（frame.getFocusedChild（）的instanceof SurfaceView）{
        SurfaceView视频=（SurfaceView）frame.getFocusedChild（）;
      }
    }
  }）;
 

解决方案

很简单，用反射。把 onShowCustomView（）法这里面的：

  android.net.Uri穆里= NULL;

尝试
{
    @燮pressWarnings（rawtypes）
    类_VideoSurfaceView_Class_ =的Class.forName（android.webkit.HTML5VideoFullScreen $ VideoSurfaceView）;

    java.lang.reflect.Field中_HTML5VideoFullScreen_Field_ = _VideoSurfaceView_Class_.getDeclaredField（本$ 0）;

    _HTML5VideoFullScreen_Field_.setAccessible（真正的）;

    对象_HTML5VideoFullScreen_Instance_ = _HTML5VideoFullScreen_Field_.get（（（的FrameLayout）视图）.getFocusedChild（））;

    @燮pressWarnings（rawtypes）
    类_HTML5VideoView_Class_ = _HTML5VideoFullScreen_Field_.getType（）getSuperclass之（）。

    java.lang.reflect.Field中_mUri_Field_ = _HTML5VideoView_Class_.getDeclaredField（穆里）;

    _mUri_Field_.setAccessible（真正的）;

    穆里=（URI）_mUri_Field_.get（_HTML5VideoFullScreen_Instance_）;
}
赶上（例外前）
{
}

如果（穆里！= NULL）
{
    //有你有，穆里是视频的URI
}
 

I am trying to get a HTML5 video URI when the user clicks the fullscreen button in the video control bar. According to this, the HTML5 video view in Android 4.0 is a SurfaceView, not a VideoView.

Could someone tell me how to get the URI in SurfaceVideoView? This is my code. Thanks a lot.

webView.setWebChromeClient(new WebChromeClient(){
  @Override
  public void onShowCustomView(View view, CustomViewCallback callback) {
    super.onShowCustomView(view, callback);
    if (view instanceof FrameLayout){
      final FrameLayout frame = (FrameLayout) view;
      if (frame.getFocusedChild() instanceof SurfaceView){
        SurfaceView video= (SurfaceView) frame.getFocusedChild();
      }
    }
  });

解决方案

Easy, using reflection. Put this inside of the onShowCustomView() method:

android.net.Uri mUri = null;

try
{
    @SuppressWarnings("rawtypes")
    Class _VideoSurfaceView_Class_ = Class.forName("android.webkit.HTML5VideoFullScreen$VideoSurfaceView");

    java.lang.reflect.Field _HTML5VideoFullScreen_Field_ = _VideoSurfaceView_Class_.getDeclaredField("this$0");

    _HTML5VideoFullScreen_Field_.setAccessible(true);

    Object _HTML5VideoFullScreen_Instance_ = _HTML5VideoFullScreen_Field_.get(((FrameLayout) view).getFocusedChild());

    @SuppressWarnings("rawtypes")
    Class _HTML5VideoView_Class_ = _HTML5VideoFullScreen_Field_.getType().getSuperclass();

    java.lang.reflect.Field _mUri_Field_ = _HTML5VideoView_Class_.getDeclaredField("mUri");

    _mUri_Field_.setAccessible(true);

    mUri =  (Uri) _mUri_Field_.get(_HTML5VideoFullScreen_Instance_);
}
catch (Exception ex)
{   
}

if (mUri != null)
{
    // There you have, mUri is the URI of the video
}
