ExpandableFab

A highly customizable Android widget that displays the available actions of a UI via an expandable set of floating action buttons - with optional labels and fluid animations.

Designed to be screen orientation aware, so it can display different elements from portrait to landscape.

Examples

A working Android app filled with some common use cases and customizations of the ExpandableFab widget can be found and built under examples. Below are a few gifs of the widget in use (this isn’t an exhaustive list - the ExpandableFab can do so much more!).

Usage

Consider reading our Medium articles on what the ExpandableFab is and how to use it if you prefer a more in-depth walkthrough.

Otherwise, simply include the ExpandableFab widget in your project via Gradle (replace X.X.X with the latest version shown here ):

implementation 'com.nambimobile.widgets:expandable-fab:X.X.X'

or Maven:

<dependency>
  <groupId>com.nambimobile.widgets</groupId>
  <artifactId>expandable-fab</artifactId>
  <version>X.X.X</version>
  <type>aar</type>
</dependency>

Then easily add some of the ExpandableFab widget views to your layout like so:

<!-- This is NOT a root view, but should be a child of whatever root view you choose (CoordinatorLayout, ConstraintLayout, etc) -->
<com.nambimobile.widgets.efab.ExpandableFabLayout
  android:layout_width="match_parent"
  android:layout_height="match_parent">
  <!-- The next 3 Views will only display in portrait orientation -->          
  <com.nambimobile.widgets.efab.Overlay
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:overlay_orientation="portrait"></com.nambimobile.widgets.efab.Overlay>
  <com.nambimobile.widgets.efab.ExpandableFab
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_marginBottom="@dimen/ui_margin_medium"
    android:layout_marginEnd="@dimen/ui_margin_medium"
    android:layout_marginRight="@dimen/ui_margin_medium"
    app:efab_orientation="portrait"></com.nambimobile.widgets.efab.ExpandableFab>
  <com.nambimobile.widgets.efab.FabOption
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:fab_orientation="portrait"
    app:label_text="Portrait Option 1"
    android:onClick="onClickPortraitOption1"></com.nambimobile.widgets.efab.FabOption>
  <!-- The next 3 Views will only display in landscape orientation -->
  <com.nambimobile.widgets.efab.Overlay
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:overlay_orientation="landscape"></com.nambimobile.widgets.efab.Overlay>
  <com.nambimobile.widgets.efab.ExpandableFab
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    android:layout_marginBottom="@dimen/ui_margin_medium"
    android:layout_marginEnd="@dimen/ui_margin_medium"
    android:layout_marginRight="@dimen/ui_margin_medium"
    app:efab_orientation="landscape"></com.nambimobile.widgets.efab.ExpandableFab>
  <com.nambimobile.widgets.efab.FabOption
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:fab_orientation="landscape"
    app:label_text="Landscape Option 1"
    android:onClick="onClickLandscapeOption1"></com.nambimobile.widgets.efab.FabOption>
</com.nambimobile.widgets.efab.ExpandableFabLayout>

Usage Notes

• Make sure to include the xmlns:app="http://schemas.android.com/apk/res-auto namespace in each layout file that uses the ExpandableFab widget in order to have access to custom properties.
• Setting ExpandableFabLayout’s width and height to match_parent will not impede the viewability, clickability or focusability of any other views in your layout (and is needed for children like Overlay who may need the ability to use the full screen).
• Defining separate widgets for portrait and landscape orientations is not necessary and was done above simply to showcase the widget’s orientation awareness. By default, if you only define one widget, it will automatically be used for both portrait and landscape orientations.
• Every property in every View within the ExpandableFab widget can be accessed or set programmatically and via XML layout files.
• None of the customizable properties for the widget Views were set in the example above, so they will all assume their default values automatically.
  • See the library website for a full list of every customizable property for each View, the full Kotlin/Java Docs and many more helpful notes and tips on using the ExpandableFab.
