Usage

Add a dependency to your build.gradle:

dependencies {
    compile 'com.github.clans:fab:1.2.0'
}

Add the com.github.clans.fab.FloatingActionButton to your layout XML file.

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

    <ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <com.github.clans.fab.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|right"
        android:layout_marginBottom="8dp"
        android:layout_marginRight="8dp"
        android:src="@drawable/ic_menu"
        fab:fab_colorNormal="@color/app_primary"
        fab:fab_colorPressed="@color/app_primary_pressed"
        fab:fab_colorRipple="@color/app_ripple"/>

</FrameLayout>

You can set an icon for the FloatingActionButton using android:src xml attribute. Use drawables of size 24dp as specified by guidlines. Icons of desired size can be generated with Android Asset Studio.

Floating action button

Here are all the FloatingActionButton's xml attributes with their default values which means that you don't have to set all of them:

<com.github.clans.fab.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|right"
        android:layout_marginBottom="8dp"
        android:layout_marginRight="8dp"
        android:src="@drawable/your_icon_drawable"
        app:fab_colorNormal="#DA4336"
        app:fab_colorPressed="#E75043"
        app:fab_colorRipple="#99FFFFFF"
        app:fab_showShadow="true"
        app:fab_shadowColor="#66000000"
        app:fab_shadowRadius="4dp"
        app:fab_shadowXOffset="1dp"
        app:fab_shadowYOffset="3dp"
        app:fab_size="normal"
        app:fab_showAnimation="@anim/fab_scale_up"
        app:fab_hideAnimation="@anim/fab_scale_down"
        app:fab_label="" />

All of these FloatingActionButton's attributes has their corresponding getters and setters. So you can set them programmatically.

Floating action menu

Here are all the FloatingActionMenu's xml attributes with their default values which means that you don't have to set all of them:

<com.github.clans.fab.FloatingActionMenu
        android:id="@+id/menu"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_marginRight="10dp"
        android:layout_marginBottom="10dp"
        android:layout_marginLeft="10dp"
        fab:menu_fab_size="normal"
        fab:menu_showShadow="true"
        fab:menu_shadowColor="#66000000"
        fab:menu_shadowRadius="4dp"
        fab:menu_shadowXOffset="1dp"
        fab:menu_shadowYOffset="3dp"
        fab:menu_colorNormal="#DA4336"
        fab:menu_colorPressed="#E75043"
        fab:menu_colorRipple="#99FFFFFF"
        fab:menu_animationDelayPerItem="50"
        fab:menu_icon="@drawable/fab_add"
        fab:menu_buttonSpacing="0dp"
        fab:menu_labels_margin="0dp"
        fab:menu_labels_showAnimation="@anim/fab_slide_in_from_right"
        fab:menu_labels_hideAnimation="@anim/fab_slide_out_to_right"
        fab:menu_labels_paddingTop="4dp"
        fab:menu_labels_paddingRight="8dp"
        fab:menu_labels_paddingBottom="4dp"
        fab:menu_labels_paddingLeft="8dp"
        fab:menu_labels_padding="8dp"
        fab:menu_labels_textColor="#FFFFFF"
        fab:menu_labels_textSize="14sp"
        fab:menu_labels_cornerRadius="3dp"
        fab:menu_labels_colorNormal="#333333"
        fab:menu_labels_colorPressed="#444444"
        fab:menu_labels_colorRipple="#66FFFFFF"
        fab:menu_labels_singleLine="false"
        fab:menu_labels_ellipsize="none"
        fab:menu_labels_maxLines="-1"
        fab:menu_labels_style="@style/YourCustomLabelsStyle">

        <com.github.clans.fab.FloatingActionButton
            android:id="@+id/menu_item"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_star"
            fab:fab_size="mini"
            fab:fab_label="Menu item 1" />

    </com.github.clans.fab.FloatingActionMenu>

If you're using custom style for labels - other labels attributes will be ignored.

Labels shadow preferences depends on their corresponding FloatingActionButtons' shadow preferences.
