Minimal steps needed to implement speed dial about android-extensions

With regards to the first icon that shows up, that code blocks sets it up, you can use the unfold icon there instead of the first one from the speed dial items.

        _fabExtensionAnimator = FabExtensionAnimator(expandable_fab).apply {
            speedDialItems[1].run { updateGlyphs("Hello", R.drawable.ic_unfold_less_24dp) }
        }

Next, the run guard prevents the animation from running while it is currently animating. I use a immutable UiState for this, and you're right that you don't need it in your project. You also don't need to call configure spring, that's just for the demo to change the bounciness of the spring.

Change your declaration of

expandable_fab.setOnClickListener {
            _fabExtensionAnimator.isExtended = !_fabExtensionAnimator.isExtended
        }

to

expandable_fab.setOnClickListener(_fabClickListener)

That should at least get the speed dial showing.

Finally, the mappings you have for your dismiss listener have to be updated.

dismissListener = {
                when (it) {
                    null -> Unit // means it was dismissed with no selection
                    0 -> Unit // The first item was clicked, you may want to collapse your fab here.
                    else -> Unit // Some other item was clicked
                }
            }
