FloatingActionButton

A port of Faiz Malkani's FloatingActionButton backport, which backports the Floating Action Button from Android L to API 15 and up.

Drawables contained in the FAB are 24dp, and this is the preferred size.

Instructions

1. Use a FrameLayout to layer your layouts, and place the FAB in the bottom to make it appear on top:

   <FrameLayout
       xmlns:android="http://schemas.android.com/apk/res/android"
       xmlns:tools="http://schemas.android.com/tools"
       android:layout_width="match_parent"
       android:layout_height="match_parent">
   
       <!--
       Your layouts here. Do not put anything below the FAB layout,
       unless you want it to overlap it.
       -->
   
   
       <dk.ostebaronen.floatingactionbutton.Fab
           android:id="@+id/fabbutton"
           android:layout_width="72dp"
           android:layout_height="72dp"
           android:layout_gravity="bottom|right"
           android:layout_marginBottom="16dp"
           android:layout_marginRight="16dp" />
   
   </FrameLayout>
   

2. Initialize FAB in your Activity's OnCreate() method:

   var fab = FindViewById<Fab>(Resource.Id.fabbutton);
   

3. Use the FabColor and FabDrawable methods to change the color and image inside of it:

   fab.FabColor = Color.Blue;
   fab.FabDrawable = Resources.GetDrawable(Resource.Drawable.ic_my_fab);
   

4. Use Hide() and Show() to hide and show the FAB. Use the Alpha property to set the transparency. Assign the Click event to handle user clicks on the FAB.
