MenuItem

SHOW_AS_ACTION_ALWAYS

static val SHOW_AS_ACTION_ALWAYS: Int

Always show this item as a button in an Action Bar. Use sparingly! If too many items are set to always show in the Action Bar it can crowd the Action Bar and degrade the user experience on devices with smaller screens. A good rule of thumb is to have no more than 2 items set to always show at a time.

Value: 2

SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW

static val SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW: Int

This item's action view collapses to a normal menu item. When expanded, the action view temporarily takes over a larger segment of its container.

Value: 8

SHOW_AS_ACTION_IF_ROOM

static val SHOW_AS_ACTION_IF_ROOM: Int

Show this item as a button in an Action Bar if the system decides there is room for it.

Value: 1

SHOW_AS_ACTION_NEVER

static val SHOW_AS_ACTION_NEVER: Int

Never show this item as a button in an Action Bar.

Value: 0

SHOW_AS_ACTION_WITH_TEXT

static val SHOW_AS_ACTION_WITH_TEXT: Int

When this item is in the action bar, always show it with a text label even if it also has an icon specified.

Value: 4

collapseActionView

abstract fun collapseActionView(): Boolean

Collapse the action view associated with this menu item. The menu item must have an action view set, as well as the showAsAction flag SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW. If a listener has been set using setOnActionExpandListener(android.view.MenuItem.OnActionExpandListener) it will have its OnActionExpandListener#onMenuItemActionCollapse(MenuItem) method invoked. The listener may return false from this method to prevent collapsing the action view.

expandActionView

abstract fun expandActionView(): Boolean

Expand the action view associated with this menu item. The menu item must have an action view set, as well as the showAsAction flag SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW. If a listener has been set using setOnActionExpandListener(android.view.MenuItem.OnActionExpandListener) it will have its OnActionExpandListener#onMenuItemActionExpand(MenuItem) method invoked. The listener may return false from this method to prevent expanding the action view.

Note: Setting an action provider overrides the action view set via setActionView(int) or setActionView(android.view.View).

setActionView

abstract fun setActionView(view: View?): MenuItem

Set an action view for this menu item. An action view will be displayed in place of an automatically generated menu item element in the UI when this item is shown as an action within a parent.

Note: Setting an action view overrides the action provider set via setActionProvider(android.view.ActionProvider).

setAlphabeticShortcut

abstract fun setAlphabeticShortcut(alphaChar: Char): MenuItem

Change the alphabetic shortcut associated with this item. The shortcut will be triggered when the key that generates the given character is pressed along with the corresponding modifier key. The default modifier is KeyEvent#META_CTRL_ON in case nothing is specified. Case is not significant and shortcut characters will be displayed in lower case. Note that menu items with the characters '\b' or '\n' as shortcuts will get triggered by the Delete key or Carriage Return key, respectively.

See Menu for the menu types that support shortcuts.

setAlphabeticShortcut

open fun setAlphabeticShortcut(
    alphaChar: Char, 
    alphaModifiers: Int
): MenuItem

Change the alphabetic shortcut associated with this item. The shortcut will be triggered when the key that generates the given character is pressed along with the modifier keys. Case is not significant and shortcut characters will be displayed in lower case. Note that menu items with the characters '\b' or '\n' as shortcuts will get triggered by the Delete key or Carriage Return key, respectively.

See Menu for the menu types that support shortcuts.

setCheckable

abstract fun setCheckable(checkable: Boolean): MenuItem

Control whether this item can display a check mark. Setting this does not actually display a check mark (see setChecked for that); rather, it ensures there is room in the item in which to display a check mark.

See Menu for the menu types that support check marks.

setChecked

abstract fun setChecked(checked: Boolean): MenuItem

Control whether this item is shown with a check mark. Note that you must first have enabled checking with setCheckable or else the check mark will not appear. If this item is a member of a group that contains mutually-exclusive items (set via Menu#setGroupCheckable(int, boolean, boolean), the other items in the group will be unchecked.

See Menu for the menu types that support check marks.

setContentDescription

open fun setContentDescription(contentDescription: CharSequence?): MenuItem

Change the content description associated with this menu item.

setEnabled

abstract fun setEnabled(enabled: Boolean): MenuItem

Sets whether the menu item is enabled. Disabling a menu item will not allow it to be invoked via its shortcut. The menu item will still be visible.

setIcon

abstract fun setIcon(iconRes: Int): MenuItem

Change the icon associated with this item. This icon will not always be shown, so the title should be sufficient in describing this item. See Menu for the menu types that support icons.

This method will set the resource ID of the icon which will be used to lazily get the Drawable when this item is being shown.

setIconTintBlendMode

open fun setIconTintBlendMode(blendMode: BlendMode?): MenuItem

Specifies the blending mode used to apply the tint specified by setIconTintList(android.content.res.ColorStateList) to this item's icon. The default mode is BlendMode#SRC_IN.

setIconTintList

open fun setIconTintList(tint: ColorStateList?): MenuItem

Applies a tint to this item's icon. Does not modify the current tint mode, which is PorterDuff.Mode#SRC_IN by default.

Subsequent calls to setIcon(android.graphics.drawable.Drawable) or setIcon(int) will automatically mutate the icon and apply the specified tint and tint mode using Drawable#setTintList(ColorStateList).

setIconTintMode

open fun setIconTintMode(tintMode: PorterDuff.Mode?): MenuItem

Specifies the blending mode used to apply the tint specified by setIconTintList(android.content.res.ColorStateList) to this item's icon. The default mode is PorterDuff.Mode#SRC_IN.

setIntent

abstract fun setIntent(intent: Intent?): MenuItem

Change the Intent associated with this item. By default there is no Intent associated with a menu item. If you set one, and nothing else handles the item, then the default behavior will be to call android.content.Context#startActivity with the given Intent.

Note that setIntent() can not be used with the versions of android.view.Menu#add that take a Runnable, because Runnable#run does not return a value so there is no way to tell if it handled the item. In this case it is assumed that the Runnable always handles the item, and the intent will never be started.

setNumericShortcut

abstract fun setNumericShortcut(numericChar: Char): MenuItem

Change the numeric shortcut associated with this item.

See Menu for the menu types that support shortcuts.

setNumericShortcut

open fun setNumericShortcut(

See Menu for the menu types that support shortcuts.

setOnActionExpandListener

abstract fun setOnActionExpandListener(listener: MenuItem.OnActionExpandListener?): MenuItem

Set an OnActionExpandListener on this menu item to be notified when the associated action view is expanded or collapsed. The menu item must be configured to expand or collapse its action view using the flag SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW.

setOnMenuItemClickListener

abstract fun setOnMenuItemClickListener(menuItemClickListener: MenuItem.OnMenuItemClickListener?): MenuItem

Set a custom listener for invocation of this menu item. In most situations, it is more efficient and easier to use Activity#onOptionsItemSelected(MenuItem) or Activity#onContextItemSelected(MenuItem).

setShortcut

abstract fun setShortcut(
    numericChar: Char, 
    alphaChar: Char
): MenuItem

Change both the numeric and alphabetic shortcut associated with this item. Note that the shortcut will be triggered when the key that generates the given character is pressed along with the corresponding modifier key. The default modifier is KeyEvent#META_CTRL_ON in case nothing is specified. Also note that case is not significant and that alphabetic shortcut characters will be handled in lower case.

See Menu for the menu types that support shortcuts.

setShortcut

open fun setShortcut(
    numericChar: Char, 
    alphaChar: Char, 
    numericModifiers: Int, 
    alphaModifiers: Int
): MenuItem

Change both the numeric and alphabetic shortcut associated with this item. Note that the shortcut will be triggered when the key that generates the given character is pressed along with the corresponding modifier key. Also note that case is not significant and that alphabetic shortcut characters will be handled in lower case.

See Menu for the menu types that support shortcuts.

setShowAsAction

abstract fun setShowAsAction(actionEnum: Int): Unit

Sets how this item should display in the presence of an Action Bar. The parameter actionEnum is a flag set. One of SHOW_AS_ACTION_ALWAYS, SHOW_AS_ACTION_IF_ROOM, or SHOW_AS_ACTION_NEVER should be used, and you may optionally OR the value with SHOW_AS_ACTION_WITH_TEXT. SHOW_AS_ACTION_WITH_TEXT requests that when the item is shown as an action, it should be shown with a text label.

setShowAsActionFlags

abstract fun setShowAsActionFlags(actionEnum: Int): MenuItem

Sets how this item should display in the presence of an Action Bar. The parameter actionEnum is a flag set. One of SHOW_AS_ACTION_ALWAYS, SHOW_AS_ACTION_IF_ROOM, or SHOW_AS_ACTION_NEVER should be used, and you may optionally OR the value with SHOW_AS_ACTION_WITH_TEXT. SHOW_AS_ACTION_WITH_TEXT requests that when the item is shown as an action, it should be shown with a text label.

Note: This method differs from setShowAsAction(int) only in that it returns the current MenuItem instance for call chaining.

setTitle

abstract fun setTitle(title: CharSequence?): MenuItem

Change the title associated with this item.

setTitle

abstract fun setTitle(title: Int): MenuItem

Change the title associated with this item.

Some menu types do not sufficient space to show the full title, and instead a condensed title is preferred. See Menu for more information.
