  @xhen，使用下面的代码这完美，

  in xml layout add this

  <sg.xyz.test.util.CustomVideoView
      android:id="@+id/videoview"
      android:layout_width="0dp"
      android:layout_height="0dp"
      android:layout_alignParentLeft="true"
      android:layout_alignParentRight="true"
      android:layout_alignParentBottom="true"
      android:layout_alignParentTop="true"
       />
  

  in your Fragment class call these medthods

  private MediaController mediaController;
   private Uri uri;
  
   public void setupVideo(){
   if (mediaController == null) {
                  mediaController = new
                          MediaController(mContext);
  
                  mediaController.setAnchorView(mBinding.videoview);
                  mBinding.videoview.setMediaController(mediaController);
              }
              try {
                  uri = Util.buildURiPath(resourceID);
                  mBinding.videoview.setVideoURI(uri);
  
              } catch (Exception e) {
                  Logger.debug("Error: " + e.getMessage());
                  e.printStackTrace();
              }
              mBinding.videoview.requestFocus();
              mBinding.imageView.setOnClickListener(new View.OnClickListener() {
                  @Override
                  public void onClick(View view) {
  
                      mBinding.videoview.start();
  
                      mBinding.imageView.setVisibility(View.INVISIBLE);
  
                  }
              });
              mBinding.videoview.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                  @Override
                  public void onPrepared(MediaPlayer mp) {
  
                      mp.setOnVideoSizeChangedListener(new MediaPlayer.OnVideoSizeChangedListener() {
                          @Override
                          public void onVideoSizeChanged(MediaPlayer mediaPlayer, int width, int height) {
                              mediaController.setAnchorView(mBinding.videoview);
                          }
                      });
                      Logger.debug("Duration = " +
                              mBinding.videoview.getDuration());
  
                  }
              });
              mBinding.videoview.setOnErrorListener(new MediaPlayer.OnErrorListener() {
                  @Override
                  public boolean onError(MediaPlayer mp, int what, int extra) {
                      AlertDialogFactory.buildAlertDialog(mContext, 0, R.string.video_playing_error).show();
                      return false;
                  }
              });
   }
  
  
  public static Uri buildURiPath(int resourceID)
  {
      String uriPath = String.valueOf(Uri.parse("android.resource://" + LoginActivity.PACKAGE_NAME + "/"
              +resourceID));
      Uri uri = Uri.parse(uriPath);
      return uri;
  }
  

  将此 mBinding.videoview 替换为您的 video 对象 . Now, Create CustomVideoView class

  public class CustomVideoView extends VideoView {
  
  private int width;
  private int height;
  private Context context;
  private VideoSizeChangeListener listener;
  private boolean isFullscreen;
  
  public CustomVideoView(Context context) {
      super(context);
      init(context);
  }
  
  public CustomVideoView(Context context, AttributeSet attrs) {
      super(context, attrs);
      init(context);
  }
  
  /**
   * get video screen width and height for calculate size
   *
   * @param context Context
   */
  private void init(Context context) {
      this.context = context;
      setScreenSize();
  }
  
  /**
   * calculate real screen size
   */
  private void setScreenSize() {
      Display display = ((Activity) context).getWindowManager().getDefaultDisplay();
  
      if (Build.VERSION.SDK_INT >= 17) {
          //new pleasant way to get real metrics
          DisplayMetrics realMetrics = new DisplayMetrics();
          display.getRealMetrics(realMetrics);
          width = realMetrics.widthPixels;
          height = realMetrics.heightPixels;
  
      } else if (Build.VERSION.SDK_INT >= 14) {
          //reflection for this weird in-between time
          try {
              Method mGetRawH = Display.class.getMethod("getRawHeight");
              Method mGetRawW = Display.class.getMethod("getRawWidth");
              width = (Integer) mGetRawW.invoke(display);
              height = (Integer) mGetRawH.invoke(display);
          } catch (Exception e) {
              //this may not be 100% accurate, but it's all we've got
              width = display.getWidth();
              height = display.getHeight();
          }
  
      } else {
          //This should be close, as lower API devices should not have window navigation bars
          width = display.getWidth();
          height = display.getHeight();
      }
  
      // when landscape w > h, swap it
      if (width > height) {
          int temp = width;
          width = height;
          height = temp;
      }
  }
  
  /**
   * set video size change listener
   *
   */
  public void setVideoSizeChangeListener(VideoSizeChangeListener listener) {
      this.listener = listener;
  }
  
  public interface VideoSizeChangeListener {
      /**
       * when landscape
       */
      void onFullScreen();
  
      /**
       * when portrait
       */
      void onNormalSize();
  }
  
  @Override
  public void setVideoURI(Uri uri) {
      MediaMetadataRetriever retriever = new MediaMetadataRetriever();
      retriever.setDataSource(this.getContext(), uri);
      width = Integer.parseInt(retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_WIDTH));
      height = Integer.parseInt(retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_HEIGHT));
      super.setVideoURI(uri);
      super.setVideoURI(uri);
  }
  @Override
  protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
      if (context.getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
          // full screen when landscape
          setSize(height, width);
          if (listener != null) listener.onFullScreen();
          isFullscreen = true;
      } else {
          // height = width * 9/16
          setSize(width, width * 9 / 16);
          if (listener != null) listener.onNormalSize();
          isFullscreen = false;
      }
  }
  
  /**
   * @return true: fullscreen
   */
  public boolean isFullscreen() {
      return isFullscreen;
  }
  
  /**

  public class Tab1Helloworld extends Fragment 
  { 
    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
       { View rootView = inflater.inflate(R.layout.tab1helloworld,container, false); 
  
       VideoView video = (VideoView)rootView.findViewById(R.id.videoView);
  
         video.requestFocus();

  您添加的错误的问题

  flag    Error:(33, 54) error: incompatible types: Tab1Helloworld cannot be converted to Context
  

  在这一行

  更换

  video.setMediaController(new MediaController(this));
  

  同

  video.setMediaController(new MediaController(getActivity()));
  

  也动了

  return rootView;
  

  在启动视频后到方法结束
