This is the xml file i have

<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"
    tools:context=".LoggedIn">


    <android.support.v4.view.ViewPager
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/pager">

        <com.google.android.material.tabs.TabLayout
            android:id="@+id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <com.google.android.material.tabs.TabItem
                android:icon="@drawable/b"
                android:text="tab1" />
            <com.google.android.material.tabs.TabItem
                android:icon="@drawable/b"
                android:text="tab2"/>
            <com.google.android.material.tabs.TabItem
                android:icon="@drawable/b"
                android:text="tab3"/>

        </com.google.android.material.tabs.TabLayout>

    </android.support.v4.view.ViewPager>

</RelativeLayout>

Main Activity i haven't added anything yet. this is totally practice , so if any small mistakes in code , do tell.

EDIT : i am also attaching my gradle file

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.vvdntech.design_material"
        minSdkVersion 19
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.android.support:design:28.0.0-alpha3'
}

& https://material.io/develop/android/components/tab-layout/ i am using this link where the tab is inside view pager.

thnx in advance

I found the answer from the maintainer.

theme must be android:theme="@style/Theme.AppCompat.Light.NoActionBar" or its inherit

I had the same problem with Tablayout(lib Masterial), and solved it as follows

Add style.xml

<style name="ThemeCustom.TabLayout" parent="Theme.MaterialComponents.Light"/>

layout.xml

<com.google.android.material.tabs.TabLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/ThemeCustom.TabLayout">

</com.google.android.material.tabs.TabLayout>

It solved my problem. Hope it helps others in the future.

On my activity_main it was saying only tablayout but I have changed to the com.google.android.material.tabs.TabLayout and the problem got fixed

It could be that it's looking for values which don't exist in your current app theme. Therefore, make sure your app theme starts with Theme.MaterialComponents instead of Theme.AppCompat.

The source of the error is that com.google.android.material.tabs.TabLayout does not come from the support libraries but rather from the material design library as @Doflaminhgo pointed out. 

dependencies {
    // ...
    implementation 'com.google.android.material:material:1.0.0'
    // ...
}

Reference https://github.com/material-components/material-components-android/blob/master/docs/getting-started.md

I am not sure why the Android reference documentation describes use of Material Components without apparently mentioning where to find it anywhere in the section.

As pointed here and here, your app should use a theme that inherits Theme.MaterialComponents themes or should have desired attributes.

this is a bit late, but for anyone who might be looking into this for the future:

the package you need to use is not com.google.android.material.tabs (although it is the one used in the material design website), but it is android.support.design.widget instead (both for TabLayout and TabItem). here is an example usage: 

<android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <android.support.design.widget.TabItem
            android:icon="@android:drawable/ic_menu_help"
            android:text="Active"
            android:layout_height="wrap_content"
            android:layout_width="wrap_content"/>
        <android.support.design.widget.TabItem
            android:icon="@android:drawable/ic_menu_help"
            android:text="History"
            android:layout_height="wrap_content"
            android:layout_width="wrap_content"/>
        <android.support.design.widget.TabItem
            android:icon="@android:drawable/ic_menu_help"
            android:text="Ignored"
            android:layout_height="wrap_content"
            android:layout_width="wrap_content"/>

    </android.support.design.widget.TabLayout>

Go through your support libraries in gradle file, all support libs must have the same version, probably issue of mixed versions.
