         ↳ android.widget.ActionMenuView


ActionMenuView is a presentation of a series of menu options as a View. It provides several top level options as action buttons while spilling remaining options over as items in an overflow menu. This allows applications to present packs of actions inline with specific or repeating content.

Public methods

dismissPopupMenus

Added in API level 21
public void dismissPopupMenus ()

Dismiss any popups associated with this menu view.

generateLayoutParams

Added in API level 21
public ActionMenuView.LayoutParams generateLayoutParams (AttributeSet attrs)

Returns a new set of layout parameters based on the supplied attributes set.

Parameters
attrs AttributeSet: the attributes to build the layout parameters from

Returns
ActionMenuView.LayoutParams an instance of ViewGroup.LayoutParams or one of its descendants

getMenu

Added in API level 21
public Menu getMenu ()

Returns the Menu object that this ActionMenuView is currently presenting.

Applications should use this method to obtain the ActionMenuView's Menu object and inflate or add content to it as necessary.

Returns
Menu the Menu presented by this view

getOverflowIcon

Added in API level 23
public Drawable getOverflowIcon ()

Return the current drawable used as the overflow icon.

Returns
Drawable The overflow icon drawable This value may be null.

getPopupTheme

Added in API level 21
public int getPopupTheme ()

Returns
int resource identifier of the theme used to inflate popup menus, or 0 if menus are inflated against the action menu view theme

hideOverflowMenu

Added in API level 21
public boolean hideOverflowMenu ()

Hide the overflow items from the associated menu.

Returns
boolean true if the menu was able to be hidden, false otherwise

isOverflowMenuShowing

Added in API level 21
public boolean isOverflowMenuShowing ()

Check whether the overflow menu is currently showing. This may not reflect a pending show operation in progress.

Returns
boolean true if the overflow menu is currently showing

onConfigurationChanged

Added in API level 21
public void onConfigurationChanged (Configuration newConfig)

Called when the current configuration of the resources being used by the application have changed. You can use this to decide when to reload resources that can changed based on orientation and other configuration characteristics. You only need to use this if you are not relying on the normal Activity mechanism of recreating the activity instance upon a configuration change.

Parameters
newConfig Configuration: The new resource configuration.

onDetachedFromWindow

Added in API level 21
public void onDetachedFromWindow ()

This is called when the view is detached from a window. At this point it no longer has a surface for drawing.
If you override this method you must call through to the superclass implementation.

setOnMenuItemClickListener

Added in API level 21
public void setOnMenuItemClickListener (ActionMenuView.OnMenuItemClickListener listener)

Parameters
listener ActionMenuView.OnMenuItemClickListener

setOverflowIcon

Added in API level 23
public void setOverflowIcon (Drawable icon)

Set the icon to use for the overflow button.

Parameters
icon Drawable: Drawable to set, may be null to clear the icon

setPopupTheme

Added in API level 21
public void setPopupTheme (int resId)

Specifies the theme to use when inflating popup menus. By default, uses the same theme as the action menu view itself.

Parameters
resId int: theme used to inflate popup menus

showOverflowMenu

Added in API level 21
public boolean showOverflowMenu ()

Show the overflow items from the associated menu.

Returns
boolean true if the menu was able to be shown, false otherwise

Protected methods

checkLayoutParams

Added in API level 21
protected boolean checkLayoutParams (ViewGroup.LayoutParams p)

Parameters
p ViewGroup.LayoutParams

Returns
boolean

generateDefaultLayoutParams

Added in API level 21
protected ActionMenuView.LayoutParams generateDefaultLayoutParams ()

Returns a set of layout parameters with a width of ViewGroup.LayoutParams.MATCH_PARENT and a height of ViewGroup.LayoutParams.WRAP_CONTENT when the layout's orientation is VERTICAL. When the orientation is HORIZONTAL, the width is set to LayoutParams#WRAP_CONTENT and the height to LayoutParams#WRAP_CONTENT.

Returns
ActionMenuView.LayoutParams a set of default layout parameters or null

generateLayoutParams

Added in API level 21
protected ActionMenuView.LayoutParams generateLayoutParams (ViewGroup.LayoutParams p)

Returns a safe set of layout parameters based on the supplied layout params. When a ViewGroup is passed a View whose layout params do not pass the test of checkLayoutParams(android.view.ViewGroup.LayoutParams), this method is invoked. This method should return a new set of layout params suitable for this ViewGroup, possibly by copying the appropriate attributes from the specified set of layout params.

Parameters
p ViewGroup.LayoutParams: The layout parameters to convert into a suitable set of layout parameters for this ViewGroup.

Returns
ActionMenuView.LayoutParams an instance of ViewGroup.LayoutParams or one of its descendants

onLayout

Added in API level 21
protected void onLayout (boolean changed, 
                int left, 
                int top, 
                int right, 
                int bottom)

Called from layout when this view should assign a size and position to each of its children. Derived classes with children should override this method and call layout on each of their children.

Parameters
changed boolean: This is a new size or position for this view

left int: Left position, relative to parent

top int: Top position, relative to parent

right int: Right position, relative to parent

bottom int: Bottom position, relative to parent

onMeasure

Added in API level 21
protected void onMeasure (int widthMeasureSpec, 
                int heightMeasureSpec)

Measure the view and its content to determine the measured width and the measured height. This method is invoked by measure(int, int) and should be overridden by subclasses to provide accurate and efficient measurement of their contents.

CONTRACT: When overriding this method, you must call setMeasuredDimension(int, int) to store the measured width and height of this view. Failure to do so will trigger an IllegalStateException, thrown by measure(int, int). Calling the superclass' onMeasure(int, int) is a valid use.

The base class implementation of measure defaults to the background size, unless a larger size is allowed by the MeasureSpec. Subclasses should override onMeasure(int, int) to provide better measurements of their content.

If this method is overridden, it is the subclass's responsibility to make sure the measured height and width are at least the view's minimum height and width (getSuggestedMinimumHeight() and getSuggestedMinimumWidth()).

Parameters
widthMeasureSpec int: horizontal space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.

heightMeasureSpec int: vertical space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.
