Floating Action Button Expandable

An android library that brings the float action button expandable. You can include optional contents and use everywhere.

Note: The Extended FAB is one of #MaterialDesign’s 🔥🔥🔥 components. You can get the code for implementing it on Android in the 1.1.0-alpha04 release, out now! http://bit.ly/ex_fab

Code

val fab = findViewById<FloatActionButtonExpandable>(R.id.fab)
recyclerView.addOnScrollListener(object : RecyclerView.OnScrollListener() {
    override fun onScrolled(recyclerView: RecyclerView, dx: Int, dy: Int) {
        if (dy > 0) {
            fab.collapse()
        } else {
            fab.expand()
        }
    }
})
// toggle expand, collapse
fab.toggle()
// expand
fab.expand()
// collapse
fab.collapse()

fab.setExpanded(true)
fab.setDuration(100L)
fab.setContent("Start Chat")
// drawable, resId, bitmap
fab.setIconActionButton(R.drawable.ic_message_white_24dp)
fab.setTextColor(ContextCompat.getColor(this, android.R.color.white))
fab.setBackgroundButtonColor(ContextCompat.getColor(this, R.color.bg_float_action))
// padding between the icon and text
fab.setPaddingTextIcon(resources.getDimensionPixelSize(R.dimen.padding_text_icon))
// padding inside the button
fab.setPaddingInsideButton(resources.getDimensionPixelSize(R.dimen.padding_fab))
// pixel
fab.setTextSize(resources.getDimensionPixelSize(R.dimen.text_size_fab).toFloat())
// or
fab.setTextSize(TypedValue.COMPLEX_UNIT_SP, 14f)
