Xaml Floating Action Button

A Floating Action Button implementation designed for Xamarin Forms XAML for Android

Based on James Montemagno's Floating Action Button examples here: https://github.com/jamesmontemagno/FloatingActionButton-for-Xamarin.Android

Known Issues

• When the list of objects being bound to contains duplicates the FAB will display weird hiding and showing behaviour.

How to use it

Best place to start is to clone this repo and take a look at how its used.

At this stage the control is not encapsulated in any way other than copying the necessary files from this example into your App. Steps

1. Include the Nuget Package Refractored.FloatingActionButton. This example uses v1.3.
2. Copy the following code classes into your PCL: FloatingActionButtonSize.cs, FloatingActionButtonView.cs
3. Copy the following files into your Droid project: FloatingActionButtonViewRenderer.cs. Also copy the image ic_add.png into /Resources/drawable_*
4. Use the FAB in Xaml as demonstrated below:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:fabTest1="clr-namespace:FABTest1;assembly=FABTest1"
             x:Class="FABTest1.Page1">
    <AbsoluteLayout VerticalOptions="FillAndExpand"
                    HorizontalOptions="FillAndExpand">
        <StackLayout AbsoluteLayout.LayoutFlags="All"
                     AbsoluteLayout.LayoutBounds="0,0,1,1">
            <Label Text="FAB Test 1"
                   VerticalOptions="Center"
                   HorizontalOptions="Center" />
            <ListView x:Name="MainList" 
                      ItemsSource="{Binding MyItems}"
                      VerticalOptions="FillAndExpand"/>
        </StackLayout>
        <fabTest1:FloatingActionButtonView x:Name="Fab" 
                                           AbsoluteLayout.LayoutFlags="PositionProportional" 
                                           AbsoluteLayout.LayoutBounds="1,1,AutoSize,AutoSize"
                                           ImageName="ic_add.png"
                                           ColorNormal="#ff3498db"
                                           ColorPressed="Black"
                                           ColorRipple="#ff3498db"
                                           Command="{Binding FabExecuteCommand}"
                                           ParentList="{Binding Source={x:Reference MainList}, Path=.}"/>
       
    </AbsoluteLayout>
</ContentPage>

Far from perfect

There's more than a few rough edges here. If you'd like to help improve it, be my guest. I'm also going to explore the new-ish Android Support Design. This may or may not make this better.
