Android - SurfaceViewRenderer on a floating window gets rendered out of its containing layout.

[Miguel del Amor]

I'm creating a floating popup with a surface view into it, in this manner:

 LayoutInflater.from(contextWeak.get()).inflate(R.layout.layout_floating_widget, null); int type;
 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
 type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
 } else {
 type = WindowManager.LayoutParams.TYPE_TOAST;
 }

 WindowManager.LayoutParams params = new WindowManager.LayoutParams(
 WindowManager.LayoutParams.WRAP_CONTENT,
 WindowManager.LayoutParams.WRAP_CONTENT,
 type,
 WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
 PixelFormat.TRANSLUCENT);

 //Specify the view position
 params.gravity = Gravity.LEFT | Gravity.CENTER; //Initially view will be added to top-left corner
 params.x = 0;
 params.y = 0;

 //Add the view to the window
 mWindowManager = (WindowManager) contextWeak.get().getSystemService(WINDOW_SERVICE);
 mWindowManager.addView(mFloatingView, params);

 localVideoView = mFloatingView.findViewById(R.id.local_gl_surface_view);
 remoteVideoView = mFloatingView.findViewById(R.id.remote_gl_surface_view);
 localVideoView.setZOrderOnTop(true);
 remoteVideoView.setZOrderOnTop(true);

And the xml
<?xml version="1.0" encoding="utf-8"?> 
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="wrap_content" android:layout_height="wrap_content"> 
   <!--Root container--> 
   <RelativeLayout android:id="@+id/root_container" android:layout_width="wrap_content" android:layout_height="wrap_content" tools:ignore="UselessParent">
      <RelativeLayout android:id="@+id/collapse_view" android:layout_width="wrap_content" android:visibility="visible" android:layout_height="wrap_content" android:orientation="vertical" android:background="#ccc">
      <LinearLayout android:id="@+id/video" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical"> 
          <org.webrtc.SurfaceViewRenderer android:id="@+id/remote_gl_surface_view" android:layout_width="150dp" android:layout_height="100dp" /> 
          <org.webrtc.SurfaceViewRenderer android:id="@+id/local_gl_surface_view" android:layout_width="150dp" android:layout_height="100dp" /> 
      </LinearLayout>
      <!--Close button--> 
      <ImageView android:id="@+id/close_btn" android:layout_width="20dp" android:layout_height="20dp" android:src="@drawable/ic_close" tools:ignore="ContentDescription" android:layout_toEndOf="@id/video"/> 
   </RelativeLayout> 
</RelativeLayout> 
</FrameLayout>

On Android 9 it's properly rendered and I can drag it with its content, but on Android 6 I'm seeing the SurfaceView being rendered like out of the layout and I can drag it but it drags the popup without the SurfaceView.
