hide

Added in API level 23
public void hide (long duration)

Hide the action mode view from obstructing the content below for a short duration. This only makes sense for action modes that support dynamic positioning on the screen. If this method is called again before the hide duration expires, the later hide call will cancel the former and then take effect. NOTE that there is an internal limit to how long the mode can be hidden for. It's typically about a few seconds.

Parameters
duration long: The number of milliseconds to hide for.

invalidate

Added in API level 11
public abstract void invalidate ()

Invalidate the action mode and refresh menu content. The mode's ActionMode.Callback will have its Callback.onPrepareActionMode(ActionMode, Menu) method called. If it returns true the menu will be scanned for updated content and any relevant changes will be reflected to the user.

invalidateContentRect

Added in API level 23
public void invalidateContentRect ()

Invalidate the content rect associated to this ActionMode. This only makes sense for action modes that support dynamic positioning on the screen, and provides a more efficient way to reposition it without invalidating the whole action mode.

See also:

isTitleOptional

Returns
boolean true if this action mode considers the title and subtitle fields as optional. Optional titles may not be displayed to the user.

setCustomView

Added in API level 11
public abstract void setCustomView (View view)

Set a custom view for this action mode. The custom view will take the place of the title and subtitle. Useful for things like search boxes.

Parameters
view View: Custom view to use in place of the title/subtitle.

setTitle

Added in API level 11
public abstract void setTitle (CharSequence title)

Set the title of the action mode. This method will have no visible effect if a custom view has been set.

setTitle

public abstract void setTitle (int resId)

Set the title of the action mode. This method will have no visible effect if a custom view has been set.

Parameters

setTitleOptionalHint

Added in API level 16
public void setTitleOptionalHint (boolean titleOptional)

Set whether or not the title/subtitle display for this action mode is optional.

In many cases the supplied title for an action mode is merely meant to add context and is not strictly required for the action mode to be useful. If the title is optional, the system may choose to hide the title entirely rather than truncate it due to a lack of available space.

Note that this is merely a hint; the underlying implementation may choose to ignore this setting under some circumstances.

Parameters
titleOptional boolean: true if the title only presents optional information.

setType

Added in API level 23
public void setType (int type)

Set a type for this action mode. This will affect how the system renders the action mode if it has to.

Parameters
type int: One of TYPE_PRIMARY or TYPE_FLOATING.
