Usage example

To attach a FabView to your target view, do the following.

1. Wrap target view with a FrameLayout.
2. Add de.halfbit.fabuless.FabView as the last child of that FrameLayout.
3. Configure size, location, color and icon of FabView.

That's it. Here is an example.

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:fabview="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <RelativeLayout
      android:id="@+id/fab_target"
	    android:layout_width="match_parent"
	    android:layout_height="170dp"
	    android:layout_gravity="top"
	    android:background="@color/color1">
    
      <!--
        This is yours target view with children (ommited for simplicity) 
        ... 
      -->
    
    </RelativeLayout>
    
    <!-- This is our FabView -->
    <de.halfbit.fabuless.FabView 
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@color/fab_color"
        android:paddingTop="3dp"
        android:src="@drawable/ic_favorite"
        fabview:fabuless_attachTo="@id/fab_target"
        fabview:fabuless_attachAt="bottom_right"
        fabview:fabuless_attachType="border"
        fabview:fabuless_size="normal"
        fabview:fabuless_padding="16dp"
        fabview:fabuless_revealAfterMs="300"
        />

</FrameLayout>
