Floating Action Button: Android Studio

Floating action buttons are the buttons which appear floating. These buttons can be used for primary actions set for the users. In order to implement floating action button ‘com.google.android.material:material:1.3.0-alpha02’ should be implemented in the dependencies of build.gradle(Module:app). The following code shows three different floating action button.

<androidx.constraintlayout.widget.ConstraintLayout 
   
    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"
    tools:context=".MainActivity">

    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/floatingActionButton1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginEnd="24dp"
        android:layout_marginRight="24dp"
        android:layout_marginBottom="24dp"
        android:clickable="true"
        android:tint="@android:color/black"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:srcCompat="@drawable/ic_add" />

    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/floatingActionButton2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginEnd="24dp"
        android:layout_marginRight="24dp"
        android:layout_marginBottom="24dp"
        android:clickable="true"
        android:tint="@android:color/black"
        app:layout_constraintBottom_toTopOf="@+id/floatingActionButton1"
        app:layout_constraintEnd_toEndOf="parent"
        app:srcCompat="@drawable/ic_check" />

    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/floatingActionButton3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginEnd="24dp"
        android:layout_marginRight="24dp"
        android:layout_marginBottom="24dp"
        android:clickable="true"
        android:tint="@android:color/black"
        app:layout_constraintBottom_toTopOf="@+id/floatingActionButton2"
        app:layout_constraintEnd_toEndOf="parent"
