Menus display a list of choices on temporary surfaces.
Contents
A menu displays a list of choices on a temporary surface. They appear when users interact with a button, action, or other control.
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 page.
A typical menu resource looks like this:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/option_1"
android:title="@string/option_1" />
<item android:id="@+id/option_2"
android:title="@string/option_2" />
<item android:id="@+id/option_3"
android:title="@string/option_3" />
</menu>
A typical exposed dropdown menu looks like this:
<com.google.android.material.textfield.TextInputLayout
android:id="@+id/menu"
style="@style/Widget.MaterialComponents.TextInputLayout.FilledBox.ExposedDropdownMenu"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/label">
<AutoCompleteTextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="none"
/>
</com.google.android.material.textfield.TextInputLayout>
See the dropdown menus and exposed dropdown menus sections for detailed usage information.
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 for informing the user as to 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.
Menus allow users to make a selection from multiple options. They are less prominent and take up less space than selection controls, such as a set of radio buttons.
There are two types of menus: 1. Dropdown menus (overflow, context, popup, and list popup window menus), 2. Exposed 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
MenuInflater
ContextMenu
PopupMenu
ListPopupWindow
The following example shows an overflow menu.
In code:
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
:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/option_1"
android:title="@string/option_1" />
<item android:id="@+id/option_2"
android:title="@string/option_2" />
<item android:id="@+id/option_3"
android:title="@string/option_3" />
</menu>
The following example shows a context menu that appears when a TextView
is
long pressed.
In code:
override fun onCreate(savedInstanceState: Bundle?) {
...
val contextMenuTextView = view.findViewById<TextView>(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:
<TextView
android:id="@+id/context_menu_tv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="16dp"
android:text="@string/menu_context_menu_description"/>
Alternatively, you can inflate a context menu in onCreateContextMenu
(similarly to the overflow menu):
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
:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/option_1"
android:title="@string/option_1" />
<item android:id="@+id/option_2"
android:title="@string/option_2" />
</menu>
The following example shows a popup menu when a button is clicked.
In code:
override fun onCreate(savedInstanceState: Bundle?) {
...
val button = view.findViewById<Button>(R.id.menu_button)
button.setOnClickListener { v: View ->
showMenu(v, R.menu.popup_menu)
}
}
private fun showMenu(v: View, @MenuRes menuRes: Int) {
val popup = PopupMenu(context!!, v)
popup.menuInflater.inflate(menuRes, popup.menu)
popup.setOnMenuItemClickListener { menuItem: MenuItem ->
// Respond to menu item click.
}
popup.setOnDismissListener {
// Respond to popup being dismissed.
}
// Show the popup menu.
popup.show()
}
In the layout:
<Button
android:id="@+id/menu_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/show_menu"/>
In res/menu/popup_menu.xml
:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/option_1"
android:title="@string/option_1" />
<item android:id="@+id/option_2"
android:title="@string/option_2" />
<item android:id="@+id/option_3"
android:title="@string/option_3" />
</menu>
Currently, there is no public API to add icons on popup menus. The following workaround is for API 21+, and uses library-only APIs, and is not guaranteed to work in future versions.
The following example shows a popup menu with icons.
In code:
//In the showMenu function from the previous example:
private fun showMenu(v: View, @MenuRes menuRes: Int) {
val popup = PopupMenu(context!!, v)
popup.menuInflater.inflate(menuRes, popup.menu)
...
if (popup.menu is MenuBuilder) {
val menuBuilder = popup.menu as MenuBuilder
menuBuilder.setOptionalIconsVisible(true)
for (item in menuBuilder.visibleItems) {
val iconMarginPx =
TypedValue.applyDimension(
TypedValue.COMPLEX_UNIT_DIP, ICON_MARGIN.toFloat(), resources.displayMetrics)
.toInt()
if (item.icon != null) {
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP) {
item.icon = InsetDrawable(item.icon, iconMarginPx, 0, iconMarginPx,0)
} else {
item.icon =
object : InsetDrawable(item.icon, iconMarginPx, 0, iconMarginPx, 0) {
override fun getIntrinsicWidth(): Int {
return intrinsicHeight + iconMarginPx + iconMarginPx
}
}
}
}
}
}
...
popup.show()
}
In res/menu/popup_menu.xml
:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/option_1"
android:icon="@drawable/ic_3d_rotation_24dp"
android:title="@string/option_1" />
<item android:id="@+id/option_2"
android:icon="@drawable/ic_accelerator_24dp"
android:title="@string/option_2" />
<item android:id="@+id/option_3"
android:icon="@drawable/ic_favorite_24dp"
android:title="@string/option_3" />
</menu>
The following example shows a list popup window menu when a button is clicked.
In code:
val listPopupWindowButton = view.findViewById<Button>(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("Option 1", "Option 2", "Option 3")
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:
<Button
android:id="@+id/list_popup_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/show_menu"/>
In the item layout res/layout/list_popup_window_item.xml
:
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="16dp"
android:ellipsize="end"
android:maxLines="1"
android:textAppearance="?attr/textAppearanceSubtitle1"
/>
The following are menu anatomy diagrams showing all possible elements:

Exposed dropdown menus display the currently selected menu item above the 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
and their usage, see the TextInputLayout documentation.
API and source code:
TextInputLayout
AutoCompleteTextView
MaterialAutoCompleteTextView
Note: MaterialComponentsViewInflater
auto-inflates
<AutoCompleteTextView>
to
<com.google.android.material.textfield.MaterialAutoCompleteTextView>
when
using a non-Bridge Theme.MaterialComponents.*
theme.
The following is an example of a filled exposed dropdown menu:
In the layout:
<com.google.android.material.textfield.TextInputLayout
android:id="@+id/menu"
style="@style/Widget.MaterialComponents.TextInputLayout.FilledBox.ExposedDropdownMenu"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/label">
<AutoCompleteTextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="none"
/>
</com.google.android.material.textfield.TextInputLayout>
In code:
val items = listOf("Option 1", "Option 2", "Option 3", "Option 4")
val adapter = ArrayAdapter(requireContext(), R.layout.list_item, items)
(textField.editText as? AutoCompleteTextView)?.setAdapter(adapter)
In the item layout (list_item.xml
):
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="16dp"
android:ellipsize="end"
android:maxLines="1"
android:textAppearance="?attr/textAppearanceSubtitle1"
/>
To have an outlined variation of the exposed dropdown menu, set the style
to
@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu
:
Disable the user input in the AutoCompleteTextView
to have a non editable
variation of the menu by setting android:inputType="none"
on the
AutoCompleteTextView
.
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
.
The exposed dropdown menu is made of an AutoCompleteTextView
within a
TextInputLayout
that has a dropdown menu displayed below it.
- Container
- Text
- Label
- Selection/Input text
- Trailing icon
To see all attributes that apply to the TextInputLayout
, see the
TextInputLayout documentation.

Default style theme attribute: ?attr/textInputStyle
See the full list of styles and attrs.
Menus drawers support Material Theming and can be customized in terms of color, typography and shape.
Popup, overflow, and list popup window menus support Material Theming and can be customized in terms of typography.
API and source code:
Menu
MenuInflater
ContextMenu
PopupMenu
ListPopupWindow
The following example shows a menu with Material Theming.
Using default style theme attributes (affects all menus but does not affect other components):
<style name="Theme.App" parent="Theme.MaterialComponents.*">
...
<item name="textAppearanceLargePopupMenu">@style/TextAppearance.App.Subtitle1</item>
<item name="textAppearanceSmallPopupMenu">@style/TextAppearance.App.Subtitle1</item>
<item name="popupMenuBackground">@drawable/custom_popup_background</item>
</style>
<style name="TextAppearance.App.Subtitle1" parent="TextAppearance.MaterialComponents.Subtitle1">
<item name="fontFamily">@font/rubik</item>
<item name="android:fontFamily">@font/rubik</item>
<item name="android:textColor">@color/shrine_pink_900</item>
</style>
In res/drawable/custom_popup_background
:
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="?attr/colorSurface"/>
<corners
android:radius="16dp"/>
<padding
android:bottom="8dp"
android:top="8dp"/>
</shape>
Use a custom style instead of overriding ?attr/popupMenuBackground
if you want
to set a custom background for one type of menu:
<style name="Theme.App" parent="Theme.MaterialComponents.*">
...
<item name="popupMenuStyle">@style/Widget.App.PopupMenu</item>
</style>
<style name="Widget.App.PopupMenu" parent="Widget.MaterialComponents.PopupMenu">
<item name="android:popupBackground">@drawable/custom_popupmenu_background</item>
</style>
Exposed dropdown menus support Material Theming and can be customized in terms of color, typography, and shape.
Note: The exposed dropdown menu is implemented through the
TextInputLayout
. For detailed information on how
Material text fields
work, see the TextInputLayout documentation.
API and source code:
TextInputLayout
AutoCompleteTextView
MaterialAutoCompleteTextView
The following example shows filled and outlined exposed dropdown menu types with Material Theming.
Using default style theme attributes, styles and theme overlays (themes all menus but does not affect other components):
<style name="Theme.App" parent="Theme.MaterialComponents.*">
...
<item name="textInputStyle">@style/Widget.App.ExposedDropdownMenu</item>
</style>
<style name="Widget.App.ExposedDropdownMenu" parent="Widget.MaterialComponents.TextInputLayout.*.ExposedDropdownMenu">
<item name="materialThemeOverlay">@style/ThemeOverlay.App.ExposedDropdownMenu</item>
<item name="shapeAppearance">@style/ShapeAppearance.App.SmallComponent</item>
<item name="hintTextColor">?attr/colorOnSurface</item>
<item name="endIconTint">?attr/colorOnSurface</item>
</style>
<style name="ThemeOverlay.App.ExposedDropdownMenu" parent="">
<item name="colorPrimary">@color/shrine_pink_100</item>
<item name="colorOnSurface">@color/shrine_pink_900</item>
<item name="colorError">@color/shrine_red</item>
<item name="textAppearanceSubtitle1">@style/TextAppearance.App.Subtitle1</item>
<item name="textAppearanceCaption">@style/TextAppearance.App.Caption</item>
<item name="autoCompleteTextViewStyle">@style/Widget.MaterialComponents.AutoCompleteTextView.*</item>
</style>
<style name="TextAppearance.App.Subtitle1" parent="TextAppearance.MaterialComponents.Subtitle1">
<item name="fontFamily">@font/rubik</item>
<item name="android:fontFamily">@font/rubik</item>
</style>
<style name="TextAppearance.App.Caption" parent="TextAppearance.MaterialComponents.Caption">
<item name="fontFamily">@font/rubik</item>
<item name="android:fontFamily">@font/rubik</item>
</style>
<style name="ShapeAppearance.App.SmallComponent" parent="ShapeAppearance.MaterialComponents.SmallComponent">
<item name="cornerFamily">cut</item>
<item name="cornerSize">4dp</item>
</style>
or using the style in the layout (affects only this menu):
<com.google.android.material.textfield.TextInputLayout
...
style="@style/Widget.App.ExposedDropdownMenu">
...
</com.google.android.material.textfield.TextInputLayout>
Note: When setting a materialThemeOverlay
on a custom TextInputLayout
style, set autoCompleteTextViewStyle
to either a
@style/Widget.MaterialComponents.AutoCompleteTextView.*
style or to a custom one
that inherits from that.
The TextInputLayout.*.ExposedDropdownMenu
styles set materialThemeOverlay
that overrides
autoCompleteTextViewStyle
with the specific AutoCompleteTextView
style needed. Therefore,
you don't need to specify a style tag on the AutoCompleteTextView
.
