Is it possible to use BlurView with a Snackbar?

[elizavetamikhailova]

Hello! I want to use blurView as a background for my snackbar. I configure my snackbar background like this:

private fun createSnackbar(length: Int) {
    snackBar = Snackbar.make(view, "", length)
    val layout = snackBar.view as Snackbar.SnackbarLayout
    layout.findViewById<TextView>(com.google.android.material.R.id.snackbar_text).visibility =
        View.INVISIBLE
    layout.setBackgroundColor(Color.TRANSPARENT)
    layout.addView(snackView.root, 0)
    snackView.blurView.apply {
        if (isL()) {
            outlineProvider = ViewOutlineProvider.BACKGROUND
            clipToOutline = true
        }
        background = createGradientDrawable(R.color.uikit_neutral_100_50)
    }
    if (isJ1())
        setupBlurBackground()
}

And I configure blurView like this:

@RequiresApi(Build.VERSION_CODES.JELLY_BEAN_MR1)
private fun setupBlurBackground() {
    snackView.root.post {
        snackView.blurView
            .setupWith(snackView.root.parent as ViewGroup)
            .setBlurAlgorithm(RenderScriptBlur(context))
            .setBlurRadius(blurRadius)
            .setBlurAutoUpdate(true)
            .setHasFixedTransformationMatrix(false)
            .setBlurEnabled(true)
    }
}

But it doesn't work, and BlurView doesn't blur anything :(

I'm trying to figure out why this doesn't work and can I get it to work?

Hey, Could you try replacing .setupWith(snackView.root.parent as ViewGroup) with the root of your activity/fragment?

I guess the problem is that this particular ViewGroup snackView.root.parent might not have any background? You can also debug what snackView.root.parent is referencing exactly to be sure

Yes it worked! Thank you very much!
