Badge count on Floating action button

Question

I would like to show count badge in front of Floating Action Button in android. I used FrameLayout in order to achieve that. My code is here

Answer 1

One can simply use TextView by giving custom style for floating.

        <TextView
                android:id="@+id/fabCounter"
                style="@style/Widget.Design.FloatingActionButton"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentEnd="true"
                android:layout_centerVertical="true"
                android:layout_marginEnd="10dp"
                android:padding="5dp"
                android:text="10"
                android:textColor="@android:color/black"
                android:textSize="14sp" />

        android:layout_height="wrap_content"
        android:layout_gravity="end|bottom"
        android:id="@+id/frameLayout">

        <android.support.design.widget.FloatingActionButton
            xmlns:app="http://schemas.android.com/apk/res-auto"
            android:id="@+id/listen_button"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:src="@android:color/transparent"
            app:backgroundTint="#e3e3e3" />

       <TextView
            android:id="@+id/textOne"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="10"
            android:textColor="#FFF"
            android:textSize="10sp"
            android:textStyle="bold"
            android:background="@drawable/badge_circle"/>

    </FrameLayout>

For this problem solution is android:elevation="7dp". But you are looking for something like this then use bellow code:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
     <RelativeLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:layout_alignParentBottom="true"
            android:layout_margin="@dimen/margin.2">
            <android.support.design.widget.FloatingActionButton
                android:id="@+id/fab_cart"
                android:layout_width="wrap_content"
                android:layout_height="match_parent"
                android:layout_alignParentRight="true"
                android:layout_margin="@dimen/margin.2"
                app:srcCompat="@drawable/ic_add_shopping_cart"
                app:backgroundTint="@color/colorPrimaryDark" />
            <TextView
                android:id="@+id/text_count"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:elevation="7dp"
                android:gravity="center"
                android:textColor="@color/white"
                android:layout_alignParentRight="true"
                android:textSize="@dimen/text.size.small"
                android:background="@drawable/bg_fab"
                tools:text="10" />
        </RelativeLayout>
</RelativeLayout>

Answer 4

I used the CounterFab library to achieve this.

It is as simple as adding it to your XML layout file instead of the regular FloatingActionButton and calling counterFab.setCount(10); (See usage example here).

Answer 5

As suggested by Daniel, you should not add badges to Floating Action Buttons. However, if you really have to do it, try adding this property to your TextView:

android:elevation="7dp"

Answer 6

You can use the BadgeDrawable provided by the Material Components Library.

Something like:

    fab.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            BadgeDrawable badgeDrawable = BadgeDrawable.create(MainActivity.this);
            badgeDrawable.setNumber(2);
            //Important to change the position of the Badge
            badgeDrawable.setHorizontalOffset(30);
            badgeDrawable.setVerticalOffset(20);

            BadgeUtils.attachBadgeDrawable(badgeDrawable, fab, null);

            fab.getViewTreeObserver().removeOnGlobalLayoutListener(this);
        }
    });

Currently (1.3.0-alpha02) there isn't a method to change the radius, but you can override this dimen in your project (dimens.xml):

<dimen name="mtrl_badge_with_text_radius">12dp</dimen>
