I have some trouble with object in kotlin

I need to create a variable vVideo. This variable is a class type of SurfaceViewRenderer. This class extends View and implements another class who get a function onFrame. I need to override this onFrame.

Here is what I tried: 

private var vVideo: SurfaceViewRenderer? = null

    fun startConfigurationAudioVideo() {

        vVideo = object : SurfaceViewRenderer(this) {
            override fun onFrame(frame: VideoFrame?) {
                Log.d("vVideo", "onFrame")
                super.onFrame(frame)
            }
        }

        vVideo = findViewById<SurfaceViewRenderer>(R.id.activity_display_videocast)

...

But, If I do this:

vVideo = object : SurfaceViewRenderer(this) {
            override fun onFrame(frame: VideoFrame?) {
                Log.d("vVideo", "onFrame")
                super.onFrame(frame)
            }
        }

before this vVideo = findViewById<SurfaceViewRenderer>(R.id.activity_display_videocast) I don't have a surfaceRender. And if I do inverse I don't get the Listener.

The problem is that I don't arrive to declare vVideo with her method onFrame and its surface (its View). The issue is that I can't have both in the same time.

Thanks for help!

You are creating and instantiating an anonymous class of SurfaceViewRenderer and then you are getting the one on your interface, which is a different object.

To make this work, you would have to create a new class that extends SurfaceViewRenderer and then use it on your layout.

Something like this:

package your.package.name
class SurfaceViewRendererWithFrameListener:SurfaceViewRenderer
{
    override fun onFrame(frame: VideoFrame?)
    {
        Log.d("vVideo", "onFrame")
        super.onFrame(frame)
    }
}

Then use it on your layout:

<your.package.name.SurfaceViewRendererWithFrameListener
.../>
