# Selection controls: switches

[Selection controls](https://material.io/components/selection-controls#usage)
allow the user to select options.

[Switches](https://m3.material.io/components/switch/overview) toggle the state
of a single setting on or off. They are the preferred way to adjust settings on
mobile devices.

## Design and API Documentation

*   [Google Material3 Spec](https://material.io/components/switch/overview)
*   [API Reference](https://developer.android.com/reference/com/google/android/material/switchmaterial/package-summary)

## Using switches

Before you can use Material switches, you need to add a dependency on the
Material Components for Android library. For more information, go to the
[Getting started](https://github.com/material-components/material-components-android/tree/master/docs/getting-started.md)
page.

**Note:** The `MaterialSwitch` widget provides a complete implementation of
Material Design's switch component. It extends from the support library's
`SwitchCompat` widget, but not from the framework `Switch` widget. As such, it
does not auto-inflate, unlike other selection controls, and must be explicitly
specified in layouts.

Use switches to:

*   Toggle a single item on or off, on mobile and tablet
*   Immediately activate or deactivate something

### Making switches accessible

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

## Switch

A `Switch` represents a button with two states, on and off. Switches are most
often used on mobile devices to enable and disable options in an options menu. A
switch consists of a track and thumb; the thumb moves along the track to
indicate its current state.

API and source code:

*   `MaterialSwitch`
    *   [Class definition](https://developer.android.com/reference/com/google/android/material/materialswitch/MaterialSwitch)
    *   [Class source](https://github.com/material-components/material-components-android/tree/master/lib/java/com/google/android/material/materialswitch/MaterialSwitch.java)

**Note:** Since version 1.7.0, the new `MaterialSwitch` class will replace the
obsolete `SwitchMaterial` class. In most cases you should be able to just
replace all `SwitchMaterial` class reference with `MaterialSwitch` to achieve
the default look and feel. Please refer to the following sections if you need to
customize the new styles.

**Note:** For the old `SwitchMaterial` documentation, please refer to
[Switch (deprecated)](#switch-deprecated) and
[Theming switches (deprecated)](#theming-switches-deprecated).

### Switches example

The following example shows a list of five switches.

![Example of 5 switches, the first one is toggled and the last one is disabled.](assets/switch/switch_example.png)

In the layout:

```xml
<com.google.android.material.materialswitch.MaterialSwitch
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:checked="true"
    android:text="@string/label_1"/>
<com.google.android.material.materialswitch.MaterialSwitch
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:text="@string/label_2"/>
<com.google.android.material.materialswitch.MaterialSwitch
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:text="@string/label_3"/>
<com.google.android.material.materialswitch.MaterialSwitch
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:text="@string/label_4"/>
<com.google.android.material.materialswitch.MaterialSwitch
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:enabled="false"
    android:text="@string/label_5"/>
```

In code:

```kt
// To check a switch
materialSwitch.isChecked = true

// To listen for a switch's checked/unchecked state changes
materialSwitch.setOnCheckedChangeListener { buttonView, isChecked
    // Responds to switch being checked/unchecked
}
```

![Switch states in an array. Columns are enabled, disabled, hover, focused,
pressed. Rows are on or off](assets/switch/switch_states.png)

### Styles

Element           | Style
----------------- | ------------------------------------------------
**Default style** | `Widget.Material3.CompoundButton.MaterialSwitch`

Default style theme attribute: `?attr/materialSwitchStyle`

See the full list of
[styles](https://github.com/material-components/material-components-android/tree/master/lib/java/com/google/android/material/materialswitch/res/values/styles.xml)
and
[attrs](https://github.com/material-components/material-components-android/tree/master/lib/java/com/google/android/material/materialswitch/res/values/attrs.xml).

## Theming switches

Switches support
[Material Theming](https://material.io/components/selection-controls#theming),
which can customize color and typography.

### Switch theming example

The following example shows a list of switches with Material Theming.

!["5 switches with brown text: first switch is on and has pink thumb and track"](assets/switch/switch_theming.png)

#### Implementing switch theming

Use theme attributes in `res/values/styles.xml`, which applies to all switches
and affects other components:

```xml
<style name="Theme.App" parent="Theme.Material3.*">
    ...
    <item name="colorPrimary">@color/pink_200</item>
    <item name="colorSurfaceVariant">@color/pink_100</item>
</style>

```

Use default style theme attributes, styles and theme overlays, which apply to
all switches but do not affect other components:

```xml
<style name="Theme.App" parent="Theme.Material3.*">
    ...
    <item name="materialSwitchStyle">@style/Widget.App.Switch</item>
</style>

<style name="Widget.App.Switch" parent="Widget.Material3.CompoundButton.MaterialSwitch">
    <item name="materialThemeOverlay">@style/ThemeOverlay.App.Switch</item>
</style>

<style name="ThemeOverlay.App.Switch" parent="">
    <item name="colorPrimary">@color/pink_200</item>
    <item name="colorSurfaceVariant">@color/pink_100</item>
</style>
```

Use the styles in the layout, which affects only this switch:

```xml
<com.google.android.material.materialswitch.MaterialSwitch
        ...
    style="@style/Widget.App.Switch"
    />
```

## Switch (deprecated)

### Switches example (deprecated)

API and source code:

switchmaterial.isChecked = true

// To listen for a switch's checked/unchecked state changes
switchmaterial.setOnCheckedChangeListener { buttonView, isChecked
    // Responds to switch being checked/unchecked
}
```

### Switch attributes (deprecated)

Element                    | Attribute                                  | Related method(s)                                          | Default value
-------------------------- | ------------------------------------------ | ---------------------------------------------------------- | -------------
**To use material colors** | `app:useMaterialThemeColors`               | `setUseMaterialThemeColors`<br/>`isUseMaterialThemeColors` | `true` (ignored if specific tint attrs are set)
**Min size**               | `android:minWidth`<br/>`android:minHeight` | `(set/get)MinWidth`<br/>`(set/get)MinHeight`               | `?attr/minTouchTargetSize`

The color of the switch defaults to using `?attr/colorPrimary`,
`?attr/colorPrimaryContainer`, `?attr/colorOnSurface`, and `?attr/colorOutline`
defined in your app theme. If you want to override this behavior, as you might
with a custom drawable that should not be tinted, set
`app:useMaterialThemeColors` to `false`:

```xml
<com.google.android.material.switchmaterial.SwitchMaterial
        ...
    app:useMaterialThemeColors="false"
    />
```

### Thumb attributes (deprecated)

Element       | Attribute       | Related method(s)                         | Default value
------------- | --------------- | ----------------------------------------- | -------------
**Thumb**     | `android:thumb` | `setThumbDrawable`<br/>`getThumbDrawable` | inherits from `SwitchCompat`
**Color**     | `app:thumbTint` | `setThumbTintList`<br/>`getThumbTintList` | `?attr/colorOnSurface` (unchecked)<br/>`?attr/colorPrimary` (checked)
**Elevation** | N/A             | N/A                                       | `4dp`

### Track attributes (deprecated)

Element   | Attribute       | Related method(s)                         | Default value
--------- | --------------- | ----------------------------------------- | -------------
**Track** | `app:track`     | `setTrackDrawable`<br/>`getTrackDrawable` | inherits from `SwitchCompat`
**Color** | `app:trackTint` | `setTrackTintList`<br/>`getTrackTintList` | `?attr/colorOutline` (unchecked)<br/>`?attr/colorPrimaryContainer` (checked)

### Text label attributes (deprecated)

Element        | Attribute                | Related method(s)                  | Default value
-------------- | ------------------------ | ---------------------------------- | -------------
**Text label** | `android:text`           | `setText`<br/>`getText`            | `null`
**Color**      | `android:textColor`      | `setTextColor`<br/>`getTextColors` | `?android:attr/textColorPrimaryDisableOnly`
**Typography** | `android:textAppearance` | `setTextAppearance`                | `?attr/textAppearanceBodyMedium`

### Switch states (deprecated)

Switches can be on or off. Switches have enabled, hover, focused, and pressed
states.

Display the outer radial reaction only on form factors that use touch, where
interaction may obstruct the element completely.

For desktop, the radial reaction isn't needed.

![Switch states in an array. Columns are enabled, disabled, hover, focused,
pressed. Rows are on or off](assets/switch/switch_states_deprecated.png)

### Styles (deprecated)

Element           | Style
----------------- | ----------------------------------------
**Default style** | `Widget.Material3.CompoundButton.Switch`

Default style theme attribute: `?attr/switchStyle`

See the full list of
[styles](https://github.com/material-components/material-components-android/tree/master/lib/java/com/google/android/material/switchmaterial/res/values/styles.xml)
and
[attrs](https://github.com/material-components/material-components-android/tree/master/lib/java/com/google/android/material/switchmaterial/res/values/attrs.xml).

## Theming switches (deprecated)

Switches support
[Material Theming](https://material.io/components/selection-controls#theming),
which can customize color and typography.

### Switch theming example (deprecated)

API and source code:

*   `SwitchMaterial`
    *   [Class definition](https://developer.android.com/reference/com/google/android/material/switchmaterial/SwitchMaterial)
    *   [Class source](https://github.com/material-components/material-components-android/tree/master/lib/java/com/google/android/material/switchmaterial/SwitchMaterial.java)

The following example shows a list of switches with Material Theming.

!["5 switches with brown text: first switch is on and has pink thumb and track"](assets/switch/switch_theming_deprecated.png)

#### Implementing switch theming (deprecated)

Use theme attributes in `res/values/styles.xml`, which applies to all switches
and affects other components:

```xml
<style name="Theme.App" parent="Theme.Material3.*">
    ...
    <item name="colorPrimaryContainer">@color/pink_100</item>
    <item name="colorPrimary">@color/pink_200</item>
</style>

```

Use default style theme attributes, styles and theme overlays, which apply to
all switches but do not affect other components:

```xml
<style name="Theme.App" parent="Theme.Material3.*">
    ...
    <item name="switchStyle">@style/Widget.App.Switch</item>
</style>

<style name="Widget.App.Switch" parent="Widget.Material3.CompoundButton.Switch">
    <item name="materialThemeOverlay">@style/ThemeOverlay.App.Switch</item>
</style>

<style name="ThemeOverlay.App.Switch" parent="">
    <item name="colorPrimaryContainer">@color/pink_100</item>
    <item name="colorPrimary">@color/pink_200</item>
</style>
```

Use the styles in the layout, which affects only this switch:

```xml
<com.google.android.material.switchmaterial.SwitchMaterial
        ...
    style="@style/Widget.App.Switch"
    />
```
