com.google.android.material:material:1.0.0-rc01

Layout

<com.google.android.material.chip.Chip
    android:id="@+id/chip"
    style="style/Widget.MaterialComponents.Chip.Entry"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/account"
    app:closeIconEnabled="true" />`

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

You can juste add @style/Theme.MaterialComponents.Light style attribut in xml layout like this:

<com.google.android.material.chip.Chip
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="chip"
android:theme="@style/Theme.MaterialComponents.Light"/>

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>

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 :
