Class Overview

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 Constructors

public ActionMenuView (Context context)

Added in API level 21

public ActionMenuView (Context context, AttributeSet attrs)

Added in API level 21

Public Methods

public void dismissPopupMenus ()

Added in API level 21

Dismiss any popups associated with this menu view.

public boolean dispatchPopulateAccessibilityEvent (AccessibilityEvent event)

Added in API level 21

Dispatches an AccessibilityEvent to the View first and then to its children for adding their text content to the event. Note that the event text is populated in a separate dispatch path since we add to the event not only the text of the source but also the text of all its descendants. A typical implementation will call onPopulateAccessibilityEvent(AccessibilityEvent) on the this view and then call the dispatchPopulateAccessibilityEvent(AccessibilityEvent) on each child. Override this method if custom population of the event text content is required.

If an View.AccessibilityDelegate has been specified via calling setAccessibilityDelegate(AccessibilityDelegate) its dispatchPopulateAccessibilityEvent(View, AccessibilityEvent) is responsible for handling this call.

Note: Accessibility events of certain types are not dispatched for populating the event text via this method. For details refer to AccessibilityEvent.

Parameters
event The event.
Returns
  • True if the event population was completed.

public ActionMenuView.LayoutParams generateLayoutParams (AttributeSet attrs)

Added in API level 21

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

Parameters
attrs the attributes to build the layout parameters from
Returns

public Menu getMenu ()

Added in API level 21

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
  • the Menu presented by this view

public int getPopupTheme ()

Added in API level 21

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

public boolean hideOverflowMenu ()

Added in API level 21

Hide the overflow items from the associated menu.

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

public boolean isOverflowMenuShowing ()

Added in API level 21

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

Returns
  • true if the overflow menu is currently showing

public void onConfigurationChanged (Configuration newConfig)

Added in API level 21

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 characterstics. 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 The new resource configuration.

public void onDetachedFromWindow ()

Added in API level 21

This is called when the view is detached from a window. At this point it no longer has a surface for drawing.

public void setOnMenuItemClickListener (ActionMenuView.OnMenuItemClickListener listener)

Added in API level 21

public void setPopupTheme (int resId)

Added in API level 21

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

Parameters
resId theme used to inflate popup menus

public boolean showOverflowMenu ()

Added in API level 21

Show the overflow items from the associated menu.

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

Protected Methods

protected boolean checkLayoutParams (ViewGroup.LayoutParams p)

Added in API level 21

protected ActionMenuView.LayoutParams generateDefaultLayoutParams ()

Added in API level 21

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

Returns
  • a set of default layout parameters or null

protected ActionMenuView.LayoutParams generateLayoutParams (ViewGroup.LayoutParams p)

Added in API level 21

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 The layout parameters to convert into a suitable set of layout parameters for this ViewGroup.
Returns

protected void onLayout (boolean changed, int left, int top, int right, int bottom)

Added in API level 21

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 This is a new size or position for this view
left Left position, relative to parent
top Top position, relative to parent
right Right position, relative to parent
bottom Bottom position, relative to parent

protected void onMeasure (int widthMeasureSpec, int heightMeasureSpec)

Added in API level 21

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