Class intance problem

Indoor Location
1

Hi there.
I’m adapting this void in another class because in the class IndoorLocationView is private:

private fun realXtoViewX(x: Double): Float {
val vectorToCenterX = mDrawParams.centerX - mDrawParams.locationWidth / 2 * mDrawParams.scale
return (x * mDrawParams.scale + vectorToCenterX).toFloat()
}

private fun realYtoViewY(y: Double): Float {
    val vectorToCenterY = mDrawParams.centerY - mDrawParams.locationHeight / 2 * mDrawParams.scale
    return (mDrawParams.viewHeight - (y * mDrawParams.scale + vectorToCenterY)).toFloat()
}

But when instantiating the drawParams class in the class where I want to use it:

private val mDrawParams = DrawParams()

can’t find the class reference, help me please
Best regards.
