Design and API Documentation

Using buttons

Before you can use Material buttons, you need to add a dependency to the Material Components for Android library. For more information, go to the Getting started page.

Note: <Button> is auto-inflated as <com.google.android.material.button.MaterialButton> via MaterialComponentsViewInflater when using a Theme.Material3.* theme.

Making buttons accessible

Buttons support content labeling for accessibility and are readable by most screen readers, such as TalkBack. Text rendered in buttons is automatically provided to accessibility services. Additional content labels are usually unnecessary.

For more information on content labels, go to the Android accessibility help guide.

Types

There are five types of common buttons: 1. Elevated button, 2. Filled button, 3. Filled tonal button, 4. Outlined button, 5. Text button.

Toggle button is an additional pattern using a segmented container or icon.

"Button types - elevated, filled, filled tonal, outlined and text."

Elevated button

Elevated buttons are essentially outlined buttons with a shadow. To prevent shadow creep, only use them when absolutely necessary, such as when the button requires visual separation from a patterned background.

Elevated button examples

API and source code:

The following example shows an elevated button with a text label.

"Elevated button with purple text 'Elevated button' over a white background."

In the layout:

xml
<Button
    style="@style/Widget.Material3.Button.ElevatedButton"
    android:id="@+id/elevatedButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Elevated button"
/>

In code:

kt
elevatedButton.setOnClickListener {
    // Respond to button press
}

Adding an icon to an elevated button

The following example shows an elevated button with an icon.

"Elevated button with purple text 'Elevated button', grey border and '+' icon
over a white background."

In the layout:

xml
<Button
    style="@style/Widget.Material3.Button.ElevatedButton.Icon"
    ...
    app:icon="@drawable/ic_add_24dp"
/>

Anatomy and key properties

An elevated button has a text label, a stroked container and an optional icon.

Filled button

Filled button's contrasting surface color makes it the most prominent button after the FAB. It’s used for final or unblocking actions in a flow.

Note The filled button is the default style if the style is not set.

Filled button examples

API and source code:

The following example shows a filled button with a text label and a filled container.

"Filled button with white text 'Filled button' and purple container over a
white background."

In the layout:

xml
<Button
    android:id="@+id/filledButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Filled button"
/>

Note: Since this is the default type, you don't need to specify a style tag as long as you are using a Material Components Theme. If not, set the style to @style/Widget.Material3.Button.

In code:

kt
filledButton.setOnClickListener {
    // Respond to button press
}

Adding an icon to a filled button

The following example shows a filled button with an icon.

"Filled button with white text 'Filled button', purple container and '+' icon
over a white background."

Button groups

Button groups organize buttons and add interactions between them.

There are two types of button groups based on their shapes:

Button group

The default button group contains multiple related individual buttons. The individual button's shape is preserved.

Examples of using default button group

        android:text="Button 3"
    />
</com.google.android.material.button.MaterialButtonGroup>

Connected button group

In addition to standard button groups, connected button group also overrides the individual button's shape to make them visually more belong to a group with 2dp spacing, 8dp inner corners, and fully rounded outer corners.

Examples of using connected button group

Connected button group examples

Source code:

The following example shows a connected button group with three buttons that have text labels. To correctly style a button group as connected button group, the specific style needs to be set.

Toggle button groups

Toggle button group (Segmented buttons) can be used to select from a group of choices.

There are two types of toggle buttons can be placed in a toggle button group:

Toggle button

To emphasize groups of related toggle buttons, a group should share a common container.

Toggle button examples

Icon

Icons can be used as toggle buttons when they allow selection, or deselection, of a single choice, such as marking an item as a favorite.

Icon example

API and source code:

Note: The CheckBox API is just one of several inputs that can implement the icon button. See other selection controls for more details.

The following example shows an icon that can be used independently or in items of a RecyclerView.

Toggle icon example showing 4 images, heart icon in the upper-right corner of
each image

In the layout:

xml
<CheckBox
    android:id="@+id/icon"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:button="@drawable/sl_favourite_24dp"
    app:buttonTint="@android:color/white"
/>

In res/drawable/sl_favourite_24dp.xml:

xml
<selector>
    <item
        android:drawable="@drawable/ic_favourite_outlined_24dp"
        android:state_checked="false"
    />
    <item
        android:drawable="@drawable/ic_favourite_filled_24dp"
        android:state_checked="true"
    />
    <item android:drawable="@drawable/ic_favourite_outlined_24dp" />
</selector>

In code:

kt
icon.setOnCheckedChangeListener { checkBox, isChecked ->
    // Respond to icon toggle
}

Icon button

Icon buttons help users take supplementary actions with a single tap. There are two types of icon buttons: standard and contained.

  • Standard icon button: By default icon buttons will not have a container.
  • Contained icon button: Optionally, it is possible to have a container around the icon.

See Icon button examples section below for more information.

Usage

  • Icon buttons should be used when a compact button is required, such as in a toolbar.
  • Icon buttons can take the form of a wide range of system icons.
  • Ensure the meaning of the icon is unambiguous.
  • Ensure that the tooltip describes the button’s action, rather than the icon.

Note: The examples below show how to create an icon button using Button which will be inflated to MaterialButton when using a Material theme. There is a known performance issue where MaterialButton takes longer to initialize when compared to ImageButton or AppCompatImageButton, in large part because MaterialButton extends from AppCompatButton which supports more than just icon buttons. Consider using those pure icon button alternatives if the extra latency causes a noticeable issue for your app.

Theming buttons

Buttons support Material Theming and can be customized in terms of color, typography and shape.

Button theming example

API and source code:

The following example shows text, outlined and filled button types with Material Theming.

"Button theming with three buttons - text, outlined and filled - with pink
color theming and cut corners."

Implementing button theming

Use theme attributes and styles in res/values/styles.xml to add the theme to all buttons. This affects other components:

xml
<style name="Theme.App" parent="Theme.Material3.*">
    ...
    <item name="colorPrimary">@color/shrine_pink_100</item>
    <item name="colorOnPrimary">@color/shrine_pink_900</item>
    <item name="textAppearanceLabelLarge">@style/TextAppearance.App.Button</item>
    <item name="shapeAppearanceSmallComponent">@style/ShapeAppearance.App.SmallComponent</item>
</style>

<style name="TextAppearance.App.Button" parent="TextAppearance.Material3.LabelLarge">
    <item name="fontFamily">@font/rubik</item>
    <item name="android:fontFamily">@font/rubik</item>
</style>

<style name="ShapeAppearance.App.SmallComponent" parent="ShapeAppearance.Material3.SmallComponent">
    <item name="cornerFamily">cut</item>
    <item name="cornerSize">4dp</item>
</style>

Use default style theme attributes, styles and theme overlays. This adds the theme to all buttons but does not affect other components:

xml
<style name="Theme.App" parent="Theme.Material3.*">
    ...
    <item name="borderlessButtonStyle">@style/Widget.App.Button.TextButton</item>
    <item name="materialButtonOutlinedStyle">@style/Widget.App.Button.OutlinedButton</item>
    <item name="materialButtonStyle">@style/Widget.App.Button</item>
</style>

<style name="Widget.App.Button.TextButton" parent="Widget.Material3.Button.TextButton">
    <item name="materialThemeOverlay">@style/ThemeOverlay.App.Button.TextButton</item>
    <item name="android:textAppearance">@style/TextAppearance.App.Button</item>
    <item name="shapeAppearance">@style/ShapeAppearance.App.SmallComponent</item>
</style>

<style name="Widget.App.Button.OutlinedButton" parent="Widget.Material3.Button.OutlinedButton">
    <item name="materialThemeOverlay">@style/ThemeOverlay.App.Button.TextButton</item>
    <item name="android:textAppearance">@style/TextAppearance.App.Button</item>
    <item name="shapeAppearance">@style/ShapeAppearance.App.SmallComponent</item>
</style>

<style name="Widget.App.Button" parent="Widget.Material3.Button">
    <item name="materialThemeOverlay">@style/ThemeOverlay.App.Button</item>
    <item name="android:textAppearance">@style/TextAppearance.App.Button</item>
    <item name="shapeAppearance">@style/ShapeAppearance.App.SmallComponent</item>
</style>

<style name="ThemeOverlay.App.Button.TextButton" parent="ThemeOverlay.Material3.Button.TextButton">
    <item name="colorOnContainer">@color/shrine_pink_900</item>
</style>

<style name="ThemeOverlay.App.Button" parent="ThemeOverlay.Material3.Button">
    <item name="colorContainer">@color/shrine_pink_100</item>
    <item name="colorOnContainer">@color/shrine_pink_900</item>
</style>

Use one of the styles in the layout. That will affect only this button:

xml
<Button
    style="@style/Widget.App.Button"
    ...
/>
