Update your app theme to inherit from one of these themes:

Theme.MaterialComponents
Theme.MaterialComponents.NoActionBar
Theme.MaterialComponents.Light
Theme.MaterialComponents.Light.NoActionBar
Theme.MaterialComponents.Light.DarkActionBar

For example:

<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">

Note: Using a Material Components theme enables a custom view inflater

Finally Got a solution as how to generate chips dynamically using new material chips

Google has not provided any documentation for chipsInput layout or how to make a gmail address like layout. Using ChipDrawable won't give delete operation on chip option as can't call setOnCloseIconClickListener. I was able to do using HorizontalScrollView, ChipGroup and EditText

Here's my code sample :

Add the following new theme attributes to your existing app theme:

<style name="Theme.MyApp" parent="Theme.AppCompat">

    <!-- Original AppCompat attributes. -->
    <item name="colorPrimary">@color/my_app_primary_color</item>
    <item name="colorPrimaryDark">@color/my_app_primary_dark_color</item>
    <item name="colorAccent">@color/my_app_accent_color</item>

    <!-- New MaterialComponents attributes. -->
    <item name="colorSecondary">?attr/colorPrimary</item>
    <item name="scrimBackground">@color/mtrl_scrim_color</item>
    <item name="textAppearanceHeadline1">@style/TextAppearance.MaterialComponents.Headline1</item>
    <item name="textAppearanceHeadline2">@style/TextAppearance.MaterialComponents.Headline2</item>
    <item name="textAppearanceHeadline3">@style/TextAppearance.MaterialComponents.Headline3</item>
    <item name="textAppearanceHeadline4">@style/TextAppearance.MaterialComponents.Headline4</item>
    <item name="textAppearanceHeadline5">@style/TextAppearance.MaterialComponents.Headline5</item>
    <item name="textAppearanceHeadline6">@style/TextAppearance.MaterialComponents.Headline6</item>
    <item name="textAppearanceSubtitle1">@style/TextAppearance.MaterialComponents.Subtitle1</item>
    <item name="textAppearanceSubtitle2">@style/TextAppearance.MaterialComponents.Subtitle2</item>
    <item name="textAppearanceBody1">@style/TextAppearance.MaterialComponents.Body1</item>
    <item name="textAppearanceBody2">@style/TextAppearance.MaterialComponents.Body2</item>
    <item name="textAppearanceCaption">@style/TextAppearance.MaterialComponents.Caption</item>
    <item name="textAppearanceButton">@style/TextAppearance.MaterialComponents.Button</item>
    <item name="textAppearanceOverline">@style/TextAppearance.MaterialComponents.Overline</item>

</style>

Add chip component which is included in the android support library.

implementation 'com.android.support:design:28.0.0-rc01'

<android.support.design.chip.Chip
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 

    />

For More Reference

Edited

Add this to your gradle file

 implementation group: 'com.google.android.material', name: 'material', version: '1.0.0-alpha1'

xml

    <com.google.android.material.chip.Chip
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:chipText="MATERIAL CHIP" />
