Learn how to work with layouts in Compose. \n[Card in Material 3 →](/develop/ui/compose/components/card) \n\n\u003cbr /\u003e\n\n| **Note:** For a better user experience, see [Material Design Cards](https://m3.material.io/components/cards/overview).\n\nApps often need to display data in similarly styled containers, such as\ncontainers that hold information about the items in a list. The system provides\nthe [`CardView`](/reference/androidx/cardview/widget/CardView) API for you to\nshow information in *cards* that have a consistent look across the platform. For\nexample, cards have a default elevation above their containing view group, so\nthe system draws shadows below them. Cards provide a way to contain a group of\nviews while providing a consistent style for the container.\n**Figure 1.** An app UI based on cards.\n\nAdd the dependencies\n--------------------\n\nThe `CardView` widget is part of [AndroidX](/jetpack/androidx). To use it in\nyour project, add the following dependency to your app module's `build.gradle`\nfile: \n\n### Groovy\n\n```groovy\ndependencies {\n implementation \"androidx.cardview:cardview:1.0.0\"\n}\n```\n\n### Kotlin\n\n```kotlin\ndependencies {\n implementation(\"androidx.cardview:cardview:1.0.0\")\n}\n```\n\nCreate cards\n------------\n\nTo use a `CardView`, add it to your layout file. Use it as a view group to\ncontain other views. In the following example, the `CardView` contains an\n`ImageView` and a few `TextViews` to display some information to the user: \n\n \u003c?xml version=\"1.0\" encoding=\"utf-8\"?\u003e\n \u003candroidx.constraintlayout.widget.ConstraintLayout\n xmlns:android=\"http://schemas.android.com/apk/res/android\"\n xmlns:app=\"http://schemas.android.com/apk/res-auto\"\n android:padding=\"16dp\"\n android:background=\"#E0F7FA\"\n android:layout_width=\"match_parent\"\n android:layout_height=\"match_parent\"\u003e\n\n \u003candroidx.cardview.widget.CardView\n android:layout_width=\"match_parent\"\n android:layout_height=\"wrap_content\"\n app:layout_constraintBottom_toBottomOf=\"parent\"\n app:layout_constraintEnd_toEndOf=\"parent\"\n app:layout_constraintStart_toStartOf=\"parent\"\n app:layout_constraintTop_toTopOf=\"parent\"\u003e\n\n \u003candroidx.constraintlayout.widget.ConstraintLayout\n android:padding=\"4dp\"\n android:layout_width=\"match_parent\"\n android:layout_height=\"match_parent\"\u003e\n\n \u003cImageView\n android:id=\"@+id/header_image\"\n android:layout_width=\"match_parent\"\n android:layout_height=\"200dp\"\n android:src=\"@drawable/logo\"\n app:layout_constraintEnd_toEndOf=\"parent\"\n app:layout_constraintStart_toStartOf=\"parent\"\n app:layout_constraintTop_toTopOf=\"parent\" /\u003e\n\n \u003cTextView\n android:id=\"@+id/title\"\n style=\"@style/TextAppearance.MaterialComponents.Headline3\"\n android:layout_width=\"match_parent\"\n android:layout_height=\"wrap_content\"\n android:layout_marginTop=\"4dp\"\n android:text=\"I'm a title\"\n app:layout_constraintEnd_toEndOf=\"parent\"\n app:layout_constraintStart_toStartOf=\"parent\"\n app:layout_constraintTop_toBottomOf=\"@id/header_image\" /\u003e\n\n \u003cTextView\n android:id=\"@+id/subhead\"\n style=\"@style/TextAppearance.MaterialComponents.Subtitle2\"\n android:layout_width=\"match_parent\"\n android:layout_height=\"wrap_content\"\n android:layout_marginTop=\"4dp\"\n android:text=\"I'm a subhead\"\n app:layout_constraintEnd_toEndOf=\"parent\"\n app:layout_constraintStart_toStartOf=\"parent\"\n app:layout_constraintTop_toBottomOf=\"@id/title\" /\u003e\n\n \u003cTextView\n android:id=\"@+id/body\"\n style=\"@style/TextAppearance.MaterialComponents.Body1\"\n android:layout_width=\"match_parent\"\n android:layout_height=\"wrap_content\"\n android:layout_marginTop=\"4dp\"\n android:text=\"I'm a supporting text.

You can provide a custom elevation\nfor a card with the `card_view:cardElevation` attribute. A card at a higher\nelevation has a more pronounced shadow, and a card at a lower elevation has a\nlighter shadow. `CardView` uses real elevation and dynamic shadows on Android\n5.0 (API level 21) and higher.\n\nUse these properties to customize the appearance of the `CardView` widget:\n\n- To set the corner radius in your layouts, use the `card_view:cardCornerRadius` attribute.\n- To set the corner radius in your code, use the `CardView.setRadius` method.\n- To set the background color of a card, use the `card_view:cardBackgroundColor` attribute."]]
