如何从另一个java类调用私有函数?

我使用ExoPlayer并需要从另一个类调用私有函数:

调用函数:

getRendererBuilder(MediaSourceType, Uri, MediaUtil.MediaType)

我得到了MediaSourceType,Uri和MediaUtil.MediaType,因为这个函数隐藏在类中,它定义如下:

   public class EMVideoView
          extends RelativeLayout
          implements AudioCapabilitiesReceiver.Listener, VideoTextureView.OnSizeChangeListener {
   private RenderBuilder getRendererBuilder(MediaSourceType renderType, Uri uri, MediaUtil.MediaType defaultMediaType)
   {
       switch (renderType)
       {
           case HLS: 
               return new HlsRenderBuilder(getContext().getApplicationContext(), getUserAgent(), uri.toString());
           case DASH: 
               return new DashRenderBuilder(getContext().getApplicationContext(), getUserAgent(), uri.toString());
           case SMOOTH_STREAM: 
               return new SmoothStreamRenderBuilder(getContext().getApplicationContext(), getUserAgent(), uri.toString());
        }
        return new RenderBuilder(getContext().getApplicationContext(), getUserAgent(), uri.toString());
   }

我正在使用这个课程

  public class ExoPlayer extends ViewWrapper<EMVideoView> {
        // HERE I NEED TO CALL getRendererBuilder and pass the parameters
        EMVideoView.setVideoURI(Uri, getRendererBuilder(renderType, uri, defaultMediaType));
  }

如何从我的班级调用私函数getRendererBuilder? 我是初学者,需要完成包装库...所以示例代码将非常好学习。

感谢。
