Make gradient start further away from end of view with GradientDrawable

I am trying to set the background of a view to have a gradient whose color is generated from the Palette api

The gradient will go from a solid and fade out but I want the solid portion to take up a majority of the background. Right now it starts solid and then gradually fades out over the view width, I want it to where it will start fading out from around the center of the view width.

Here is what I do

            Palette.from(resource!!.toBitmap()).generate {
                if (it != null) {
                    val paletteColor = it.getDarkVibrantColor("#000000".toColorInt())

                    val gradientDrawable = GradientDrawable(
                        GradientDrawable.Orientation.LEFT_RIGHT,
                        intArrayOf(colorWithAlpha(paletteColor, 0f), colorWithAlpha(paletteColor, 1.0f))
                    )
                    gradientDrawable.cornerRadius = 0f
                    _contentTextBackground.background = gradientDrawable
                }
            }

Is there a way to set the gradient to start further away from the end of the view?
