A FloatingActionButton subclass that shows a counter badge on right top corner
It's also used by Louvre library.
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>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 1The 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:badgeBackgroundColorapp:badgeTextColorapp:badgePositionasRightTop,LeftBottom,LeftToporRightBottom
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" />See more at the sample
