This is an Android project allowing to animate a Floating Action Button menu with "lava" animation.

Just add LavaFab view in your layout XML and LavaFab library in your project via Gradle:

dependencies {
  implementation 'com.bitvale:lavafab:1.0.1'
}

<com.bitvale.lavafab.LavaFab
    android:id="@+id/lava_fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:lavaBackgroundColor="@color/color_pink"
    app:lavaChild="left|top"
    app:lavaParentSize="@dimen/fab_size"
    app:lavaParentIcon="@drawable/ic_parent"
    app:lavaLeftIcon="@drawable/ic_left"
    app:lavaTopIcon="@drawable/ic_right" 
    app:lavaDrawShadow="true" />

You must use the following properties in your XML to change your LavaFab.

• app:lavaBackgroundColor (color) -> default ?attr/colorAccent
• app:lavaParentSize (dimension) -> default 56dp
• app:lavaDrawShadow (boolean) -> default false
• app:lavaChild (flag) -> default left|top
• app:lavaParentIcon (drawable) -> default none
• app:lavaLeftIcon (drawable) -> default none
• app:lavaLeftTopIcon (drawable) -> default none
• app:lavaTopIcon (drawable) -> default none
• app:lavaRightTopIcon (drawable) -> default none
• app:lavaRightIcon (drawable) -> default none
• app:lavaRightBottomIcon (drawable) -> default none
• app:lavaBottomIcon (drawable) -> default none
• app:lavaLeftBottomIcon (drawable) -> default none

with(lava_fab) {
    setLavaBackgroundResColor(R.color.fab_color)
    setParentOnClickListener { lava_fab_center.trigger() }
    setChildOnClickListener(Child.TOP) { lava_fab_center.collapse() }
    setChildOnClickListener(Child.LEFT) { // some action }
    enableShadow()
    setParentIcon(R.drawable.ic_parent)
    setChildIcon(Child.TOP, R.drawable.ic_child_top)
    setChildIcon(Child.LEFT, R.drawable.ic_child_left)
}
