CounterFab

A FloatingActionButton subclass that shows a counter badge on right top corner

It's also used by Louvre library.

Installation

Include the library in your build.gradle (check badge at top for latest version)

dependencies{
    compile 'com.github.andremion:counterfab:x.y.z'
}

or in your pom.xml if you are using Maven

<dependency>
  <groupId>com.github.andremion</groupId>
  <artifactId>counterfab</artifactId>
  <version>x.y.z</version>
  <type>pom</type>
</dependency>

Usage

Add it as a regular FloatingActionButton on layout…

<com.andremion.counterfab.CounterFab
        android:id="@+id/counter_fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_add_white_24dp" />

and programmatically you can use one of these methods:

CounterFab counterFab = (CounterFab) findViewById(R.id.counter_fab);
counterFab.setCount(10); // Set the count value to show on badge
counterFab.increase(); // Increase the current count value by 1
counterFab.decrease(); // Decrease the current count value by 1

Customization

The recommended way to customize the background color is by using the app:backgroundTint attribute

<com.andremion.counterfab.CounterFab
        android:id="@+id/counter_fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:backgroundTint="@color/colorAccent"
        android:src="@drawable/ic_add_white_24dp" />

To change the badge style you can use these attributes:

• app:badgeBackgroundColor
• app:badgeTextColor
• app:badgePosition as RightTop, LeftBottom, LeftTop or RightBottom

For example:

<com.andremion.counterfab.CounterFab
        android:id="@+id/counter_fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:badgeBackgroundColor="@color/red"
        app:badgeTextColor="@color/white"
        app:badgePosition="RightTop"
        android:src="@drawable/ic_add_white_24dp" />
