Yes.

Basic steps:

TextureView
See:

Create ExoPlayer with TextureView instead of SurfaceView

There are some cases where you need to create an ExoPlayer with TextureView. TextureView can be customized more easily. 1. Add to manifest editor: CreateResource(layout, layout1.xml, ) 2. Private Sub GetSimpleExoPlayerView As SimpleExoPlayerView Dim x As XmlLayoutBuilder...

or
Test

   Private SimpleExoPlayer1 As SimpleExoPlayer
   Private SimpleExoPlayerView1 As SimpleExoPlayerView
   ...
   ...
   ...
 
   Dim joView As JavaObject = SimpleExoPlayerView1
   joView.RunMethod("setUseTextureView", Array(True))

Configure gesture detector

 Dim jo As JavaObject = SimpleExoPlayerView1
    Dim TouchListener As Object = jo.CreateEvent("android.view.View$OnTouchListener", "TouchListener", False)
    jo.RunMethod("setOnTouchListener", Array(TouchListener))

    Dim ScaleListener As Object = jo.CreateEventFromUI("android.view.ScaleGestureDetector$OnScaleGestureListener", "ScaleListener", True)
    Dim ctxt As JavaObject
    ctxt.InitializeContext
    ScaleDetector.InitializeNewInstance("android.view.ScaleGestureDetector", Array(ctxt, ScaleListener))

Sub ScaleListener_OnScale(Detector As JavaObject) As Boolean
    Dim scaleFactor As Float = Detector.RunMethod("getScaleFactor", Null)
    Dim newScale As Float = CurrentScale * scaleFactor
    If newScale < MinScale Then newScale = MinScale
    If newScale > MaxScale Then newScale = MaxScale
    CurrentScale = newScale
    ApplyTransform '---> Sub:  ZOOM + PAN TO VIDEO
    Return True
End Sub

Sub ScaleListener_OnScaleBegin(Detector As JavaObject) As Boolean
    Return True
End Sub

Sub ScaleListener_OnScaleEnd(Detector As JavaObject)
End Sub
