# Menus
[Menus](https://m3.material.io/components/menus/overview) display a list of choices on
temporary surfaces. There are two variants of menus.
1. Dropdown menu
2. Exposed dropdown menu
Menus allow users to make a selection from multiple options. They appear when
users interact with a button, action, or other control.They are less prominent
and take up less space than selection controls, such as a set of radio
buttons.
**Note:** Images use various dynamic color schemes.

## Variants of menus
### Dropdown menus
Dropdown menus display a list of options, triggered by an icon, button, or
action. Their placement varies based on the element that opens them.
API and source code:
* `Menu`
* [Class definition](https://developer.android.com/reference/android/view/Menu)
* `MenuInflater`
* [Class definition](https://developer.android.com/reference/android/view/MenuInflater)
* `ContextMenu`
* [Class definition](https://developer.android.com/reference/android/view/ContextMenu)
* `PopupMenu`
* [Class definition](https://developer.android.com/reference/androidx/appcompat/widget/PopupMenu)
* `ListPopupWindow`
* [Class definition](https://developer.android.com/reference/androidx/appcompat/widget/ListPopupWindow)
#### Dropdown menu examples
Overflow menus
The following example shows an overflow menu.
In code:
```kt
override fun onCreateOptionsMenu(menu: Menu): Boolean {
val inflater: MenuInflater = menuInflater
inflater.inflate(R.menu.overflow_menu, menu)
return true
}
```
In `res/menu/overflow_menu.xml`:
```xml
```
Context menus
The following example shows a context menu that appears when a `TextView` is
pressed for a designated amount of time.
In code:
```kt
override fun onCreate(savedInstanceState: Bundle?) {
...
val contextMenuTextView = view.findViewById(R.id.context_menu_tv)
// Register context menu for TextView
registerForContextMenu(contextMenuTextView)
}
override fun onCreateContextMenu(menu: ContextMenu, v: View, menuInfo: ContextMenu.ContextMenuInfo?) {
val contextMenuTextView = v as TextView
val context = context
// Add menu items via menu.add
menu.add(R.string.option_1)
.setOnMenuItemClickListener { item: MenuItem? ->
// Respond to item click.
}
menu.add(R.string.option_2)
.setOnMenuItemClickListener { item: MenuItem? ->
// Respond to item click.
}
}
override fun onContextMenuClosed(menu: Menu) {
// Respond to context menu being closed.
}
```
In the layout:
```xml
```
Alternatively, you can inflate a context menu in `onCreateContextMenu` (as with
the overflow menu):
```kt
override fun onCreateContextMenu(menu: ContextMenu, v: View, menuInfo: ContextMenu.ContextMenuInfo?) {
super.onCreateContextMenu(menu, v, menuInfo)
val inflater: MenuInflater = menuInflater
inflater.inflate(R.menu.context_menu, menu)
}
// Then, to handle clicks:
override fun onContextItemSelected(item: MenuItem): Boolean {
val info = item.menuInfo as AdapterView.AdapterContextMenuInfo
return when (item.itemId) {
R.id.option_1 -> {
// Respond to context menu item 1 click.
true
}
R.id.option_2 -> {
// Respond to context menu item 2 click.
true
}
else -> super.onContextItemSelected(item)
}
}
```
with a `res/menu/context_menu.xml`:
```xml
```
Popup menus
The following example shows a popup menu that displays when a button is clicked.
In code:
```kt
override fun onCreate(savedInstanceState: Bundle?) {
...
val button = view.findViewById
List popup window menus
The following example shows a list popup window menu that appears when a button
is clicked.
In code:
```kt
val listPopupWindowButton = view.findViewById(R.id.list_popup_button)
val listPopupWindow = ListPopupWindow(context!!, null, R.attr.listPopupWindowStyle)
// Set button as the list popup's anchor
listPopupWindow.anchorView = listPopupWindowButton
// Set list popup's content
val items = listOf("Item 1", "Item 2", "Item 3", "Item 4")
val adapter = ArrayAdapter(requireContext(), R.layout.list_popup_window_item, items)
listPopupWindow.setAdapter(adapter)
// Set list popup's item click listener
listPopupWindow.setOnItemClickListener { parent: AdapterView<*>?, view: View?, position: Int, id: Long ->
// Respond to list popup window item click.
// Dismiss popup.
listPopupWindow.dismiss()
}
// Show list popup window on button click.
listPopupWindowButton.setOnClickListener { v: View? -> listPopupWindow.show() }
```
In the layout:
```xml
```
In the item layout `res/layout/list_popup_window_item.xml`:
```xml
```
### Exposed dropdown menu
Exposed dropdown menus display the currently selected menu item above a list of
options. Some variations can accept user-entered input.
**Note:** The exposed dropdown menu is implemented through the
`TextInputLayout`. For detailed information on
[Material text fields](https://material.io/design/components/text-fields.html)
and their usage, see the [TextInputLayout documentation](TextField.md).
API and source code:
* `TextInputLayout`
* [Class definition](https://developer.android.com/reference/com/google/android/material/textfield/TextInputLayout)
* [Class source](https://github.com/material-components/material-components-android/tree/master/lib/java/com/google/android/material/textfield/TextInputLayout.java)
* `AutoCompleteTextView`
* [Class definition](https://developer.android.com/reference/android/widget/AutoCompleteTextView)
* `MaterialAutoCompleteTextView`
* [Class definition](https://developer.android.com/reference/com/google/android/material/textfield/MaterialAutoCompleteTextView)
* [Class source](https://github.com/material-components/material-components-android/tree/master/lib/java/com/google/android/material/textfield/MaterialAutoCompleteTextView.java)
The exposed dropdown menu is an `AutoCompleteTextView` within a
`TextInputLayout`. It displays a dropdown menu below a text field.
**Note:** `MaterialComponentsViewInflater` auto-inflates
`` to
`` when
using `Theme.Material3.*` themes.
The following is an example of a filled exposed dropdown menu:
In the layout:
```xml
```
The string array specified by `app:simpleItems` will be used as the default
item strings for auto-completion. Or you can also set it programmatically:
```kt
val items = arrayOf("Item 1", "Item 2", "Item 3", "Item 4")
(textField.editText as? MaterialAutoCompleteTextView)?.setSimpleItems(items)
```
Alternatively, to have more control over the auto-completion items rendering,
you can also provide a custom item adapter by:
```kt
val items = listOf("Item 1", "Item 2", "Item 3", "Item 4")
val adapter = ArrayAdapter(requireContext(), R.layout.list_item, items)
(textField.editText as? AutoCompleteTextView)?.setAdapter(adapter)
```
And a custom item layout (`list_item.xml`):
```xml
```
To use the exposed dropdown menu with an outlined text field, set the `style` to
`@style/Widget.Material3.TextInputLayout.OutlinedBox.ExposedDropdownMenu`:
#### Non editable variation
For a non-editable menu, disable the user input in the `AutoCompleteTextView` by
setting `android:inputType="none"` on the `AutoCompleteTextView`.
#### Setting a default value
In order to have a pre-selected value displayed, you can call
`setText(CharSequence text, boolean filter)` on the `AutoCompleteTextView` with
the filter set to `false`.
## Code implementation
Before you can use Material menus, you need to add a dependency to 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.
### Menu examples
A typical menu resource looks like this:
```xml
```
A typical exposed dropdown menu looks like this:
```xml
```
### Making menus accessible
Menus are readable by most screen readers, such as TalkBack. Text rendered in
menus is automatically provided to accessibility services. Additional content
labels are usually unnecessary.
Android's exposed dropdown menu component APIs support both label text and
helper text, which tell the user what information is requested for a menu. While
optional, their use is strongly encouraged. For more information about this
component's accessibility, check out
[the text field's a11y section](TextField.md#making-text-fields-accessible).
## Customizing menus
### Theming menus
Menus drawers support the customization of color, typography, and shape.
#### Dropdown menu theming examples
Popup, overflow, and list popup window menus support the customization of
typography.
API and source code:
* `Menu`
* [Class definition](https://developer.android.com/reference/android/view/Menu)
* `MenuInflater`
* [Class definition](https://developer.android.com/reference/android/view/MenuInflater)
* `ContextMenu`
* [Class definition](https://developer.android.com/reference/android/view/ContextMenu)
* `PopupMenu`
* [Class definition](https://developer.android.com/reference/androidx/appcompat/widget/PopupMenu)
* `ListPopupWindow`
* [Class definition](https://developer.android.com/reference/androidx/appcompat/widget/ListPopupWindow)
The following example shows a menu with Material theming.

##### Implementing menu theming
Use default style theme attributes, which affect all menus but do not affect
other components:
```xml
```
In `res/drawable/custom_popup_background`:
```xml
```
Use a custom style instead of overriding `?attr/popupMenuBackground` if you want
to set a custom background for one type of menu:
```xml
```
#### Exposed dropdown menu theming examples
Exposed dropdown menus support
[Material theming](https://material.io/components/chips/#theming) which can
customize color, typography, and shape.
**Note:** The exposed dropdown menu is implemented through the
`TextInputLayout`. For detailed information on how
[Material text fields](https://material.io/design/components/text-fields.html)
work, see the [TextInputLayout documentation](TextField.md).
API and source code:
* `TextInputLayout`
* [Class definition](https://developer.android.com/reference/com/google/android/material/textfield/TextInputLayout)
* [Class source](https://github.com/material-components/material-components-android/tree/master/lib/java/com/google/android/material/textfield/TextInputLayout.java)
* `AutoCompleteTextView`
* [Class definition](https://developer.android.com/reference/android/widget/AutoCompleteTextView)
* `MaterialAutoCompleteTextView`
* [Class definition](https://developer.android.com/reference/com/google/android/material/textfield/MaterialAutoCompleteTextView)
* [Class source](https://github.com/material-components/material-components-android/tree/master/lib/java/com/google/android/material/textfield/MaterialAutoCompleteTextView.java)
The following example shows filled and outlined exposed dropdown menu types with
Material theming.

##### Implementing exposed dropdown menu theming
Use default style theme attributes, styles and theme overlays which adds themes
to all menus but does not affect other components:
```xml
```
or use the style in the layout, which affects only this menu:
```xml
...
```
**Note:** When setting a `materialThemeOverlay` on a custom `TextInputLayout`
style, set `autoCompleteTextViewStyle` to either a
`@style/Widget.Material3.AutoCompleteTextView.*` style or to a custom one that
inherits from that. The `TextInputLayout.*.ExposedDropdownMenu` styles set
`materialThemeOverlay` to override `autoCompleteTextViewStyle` with the
specific `AutoCompleteTextView` style needed. Therefore, you don't need to
specify a style tag on the `AutoCompleteTextView`.
