Getting started with Material Components for Android ​

1. Migration guidance ​

Take a look at our guide and codelab to help you migrate your codebase using Material Components for Android to the new Material 3 system.

Additionally, if you are still using the legacy Design Support Library, take a look at our legacy guide to help you migrate your codebase to Material Components for Android.

2. Maven library dependency ​

Material Components for Android is available through Google's Maven Repository. To use it:

  1. Open the build.gradle file for your application.

  2. Make sure that the repositories section includes Google's Maven Repository google(). For example:

    groovy
      allprojects {
    repositories {
      google()
      mavenCentral()
    }
  }

  3. Add the library to the dependencies section:

    groovy
      dependencies {
    // ...
    implementation 'com.google.android.material:material:<version>'
    // ...
  }

Visit Google's Maven Repository or MVN Repository to find the latest version of the library.

Note: In order to use the new Material3 themes and component styles, you should depend on version 1.5.0 or later.

New Namespace and AndroidX ​

If your app currently depends on the original Design Support Library, you can make use of the Refactor to AndroidX… option provided by Android Studio. Doing so will update your app's dependencies and code to use the newly packaged androidx and com.google.android.material libraries.

If you don't want to switch over to the new androidx and com.google.android.material packages yet, you can use Material Components via the com.android.support:design:28.0.0 dependency.

Note: You should not use the com.android.support and com.google.android.material dependencies in your app at the same time.

3. Android SDK compilation ​

In order to use the latest versions of Material Components for Android and the AndroidX Jetpack libraries, you will have to install the latest version of Android Studio and update your app to meet the following requirements:

4. Java 8 compilation ​

The latest Material and AndroidX Jetpack libraries now require your app to be compiled with Java 8. See the Java 8 language features and APIs documentation for more information on Java 8 support and how to enable it for your app.

5. Gradle, AGP, and Android Studio ​

When using MDC-Android version 1.7.0 and above, you will need to make sure your project is built with the following minimum requirements, in order to support the latest build features such as XML macro:

6. AppCompatActivity ​

Use AppCompatActivity to ensure that all the components work correctly. If you are unable to extend from AppCompatActivity, update your activities to use AppCompatDelegate. This will enable the AppCompat or Material versions of components to be inflated (depending on your theme), among other important things.

7. Material3 theme inheritance ​

We recommend you perform an app-wide migration by changing your app theme to inherit from a Material3 theme. Be sure to test thoroughly afterwards, since this may change the appearance and behavior of existing layout components.

Check out the new Material Theme Builder which can be used to generate your Material3 app theme, with all of the Material Color System roles filled out based on your brand colors.

Note: If you can't change your theme, you can continue to inherit from an AppCompat or MaterialComponents theme and add some new theme attributes to your theme. See the AppCompat or MaterialComponents themes section for more details.

Material3 themes ​

Here are the Material3 themes you can use to get the latest component styles and theme-level attributes, as well as their MaterialComponents equivalents when applicable.

Material3MaterialComponents
Theme.Material3.LightTheme.MaterialComponents.Light
Theme.Material3.Light.NoActionBarTheme.MaterialComponents.Light.NoActionBar
Theme.Material3.DarkTheme.MaterialComponents
Theme.Material3.Dark.NoActionBarTheme.MaterialComponents.NoActionBar
Theme.Material3.DayNightTheme.MaterialComponents.DayNight
Theme.Material3.DayNight.NoActionBarTheme.MaterialComponents.DayNight.NoActionBar
Theme.Material3.DynamicColors.LightN/A
Theme.Material3.DynamicColors.Light.NoActionBarN/A
Theme.Material3.DynamicColors.DarkN/A
Theme.Material3.DynamicColors.Dark.NoActionBarN/A
Theme.Material3.DynamicColors.DayNightN/A
Theme.Material3.DynamicColors.DayNight.NoActionBarN/A
N/ATheme.MaterialComponents.Light.DarkActionBar
N/ATheme.MaterialComponents.DayNight.DarkActionBar

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

xml
<style name="Theme.MyApp" parent="Theme.Material3.DayNight.NoActionBar">
    <!-- ... -->
</style>

For more information on how to set up theme-level attributes for your app, take a look at our Theming guide, as well as our Dark Theme guide for why it's important to inherit from the DayNight theme.

Material3 themes enable a custom view inflater, which replaces default components with their Material counterparts. Currently, this replaces the following XML components:

AppCompat or MaterialComponents Themes ​

You can incrementally test new Material components without changing your app theme. This allows you to keep your existing layouts looking and behaving the same, while introducing new components to your layout one at a time.

However, you must add the following new theme attributes to your existing app theme, or you will encounter ThemeEnforcement errors:

xml
<style name="Theme.MyApp" parent="Theme.AppCompat OR Theme.MaterialComponents">

  <!-- Original AppCompat attributes. -->
  <item name="colorPrimary">@color/my_app_primary</item>
  <item name="colorPrimaryDark">@color/my_app_primary_dark</item>

</style>

8. Add Material components ​

Take a look at our documentation for the full list of available Material components. Each component's page has specific instructions on how to implement it in your app.

Let's use text fields as an example.

Implementing a text field via XML ​

The default outlined text field XML is defined as:

xml
<com.google.android.material.textfield.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="@string/textfield_label">

  <com.google.android.material.textfield.TextInputEditText
      android:layout_width="match_parent"
      android:layout_height="wrap_content"/>
</com.google.android.material.textfield.TextInputLayout>

Note: If you are not using a theme that inherits from a Material3 theme, you will have to specify the text field style as well, via style="@style/Widget.Material3.TextInputLayout.OutlinedBox"

Other text field styles are also provided. For example, if you want a filled text field in your layout, you can apply the Material3 filled style to the text field in XML:

xml
<com.google.android.material.textfield.TextInputLayout
    style="@style/Widget.Material3.TextInputLayout.FilledBox"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="@string/textfield_label">

  <com.google.android.material.textfield.TextInputEditText
      android:layout_width="match_parent"
      android:layout_height="wrap_content"/>
</com.google.android.material.textfield.TextInputLayout>
