Answer 1

With API 28 you can simply add text to Fabs using:

Visit: https://material.io/develop/android/components/extended-floating-action-button/

 <com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_margin="8dp"
      android:contentDescription="@string/extended_fab_content_desc"
      android:text="@string/extended_fab_label"
      app:icon="@drawable/ic_plus_24px"
      app:layout_anchor="@id/app_bar"
      app:layout_anchorGravity="bottom|right|end"/>

I was needing text in a FAB but instead I just went with a TextView with a circular drawable background:

  <TextView
        android:layout_margin="10dp"
        android:layout_gravity="right"
        android:gravity="center"
        android:background="@drawable/circle_background"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#FFF"
        android:textStyle="bold"
        android:fontFamily="sans-serif"
        android:text="AuthId"
        android:textSize="15dp"
        android:elevation="10dp"/>

Here is the drawable(circle_backgroung.xml):

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">

<solid
    android:color="#666666"/>

<size
    android:width="60dp"
    android:height="60dp"/>
</shape>

Thanks to all.

Here is easy workaround which I found for this question. Works correctly for Android 4+, for Android 5+ is added specific parameter android:elevation to draw TextView over FloatingActionButton.

<FrameLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|right">

    <android.support.design.widget.FloatingActionButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@android:color/transparent" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:text="@android:string/ok"
        android:elevation="16dp"
        android:textColor="@android:color/white"
        android:textAppearance="?android:attr/textAppearanceMedium" />
</FrameLayout>
