Adding Floating Icon in Android Studio Kotlin

First of all, add the dependencies as shown in the given code below.

plugins {
    id 'com.android.application'
    id 'kotlin-android'
}

android {
    compileSdk 30

    defaultConfig {
        applicationId "com.shyptsolution.myresume"
        minSdk 23
        targetSdk 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }
}

dependencies {

    implementation 'androidx.core:core-ktx:1.6.0'
    implementation 'com.google.android.material:material:1.4.0'
    implementation 'androidx.appcompat:appcompat:1.3.1'
    implementation 'com.google.android.material:material:1.4.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.1'
    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
    implementation 'com.google.android.material:material:1.3.0-alpha03'
    implementation 'com.squareup.picasso:picasso:2.71828'
}

Then you need to add the floating icons in the XML as shown below.

First add the <com.google.android.material.floatingactionbutton.FloatingActionButton

then all the things such as icon, id, its position and everything else you want.

<?xml version="1.0" encoding="utf-8"?>
<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"

    android:background="@drawable/bgcol"
    tools:context=".MainActivity">

    <!--<com.google.android.material.bottomappbar.BottomAppBar-->
    <!--    android:layout_width="match_parent"-->
    <!--    android:layout_height="wrap_content"-->
    <!--    android:id="@+id/bottamappbar"-->
    <!--    app:layout_constraintBottom_toBottomOf="parent"-->

    <!--    >-->


    <!--</com.google.android.material.bottomappbar.BottomAppBar>-->

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:textColor="@color/white"
        android:textSize="20sp"
        app:layout_constraintBottom_toTopOf="@+id/floatinghome"

    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/floatinghome"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="10dp"
        android:src="@drawable/home"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent" />
    <!--        app:layout_anchor="@id/bottamappbar"-->
    <!--        app:layout_constraintBottom_toBottomOf="@+id/bottamappbar"-->
    <!--        app:layout_constraintEnd_toEndOf="@+id/bottamappbar"-->
    <!--        app:layout_constraintStart_toStartOf="@+id/bottamappbar" -->
    />

    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/contact"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="10dp"
        android:src="@drawable/contact_me"
        app:layout_constraintBottom_toBottomOf="parent"
        android:layout_marginLeft="20dp"
        app:layout_constraintStart_toStartOf="parent" />

    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/resume"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="10dp"
        android:src="@drawable/resume"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        android:layout_marginRight="20dp" />
</androidx.constraintlayout.widget.ConstraintLayout>
