Class ShareActionProvider

java.lang.Object

com.actionbarsherlock.view.ActionProvider

com.actionbarsherlock.widget.ShareActionProvider

public class ShareActionProvider
extends ActionProvider

This is a provider for a share action. It is responsible for creating views that enable data sharing and also to show a sub menu with sharing activities if the hosting item is placed on the overflow menu.

Here is how to use the action provider with custom backing file in a MenuItem:

 
  // In Activity#onCreateOptionsMenu
  public boolean onCreateOptionsMenu(Menu menu) {
      // Get the menu item.
      MenuItem menuItem = menu.findItem(R.id.my_menu_item);
      // Get the provider and hold onto it to set/change the share intent.
      mShareActionProvider = (ShareActionProvider) menuItem.getActionProvider();
      // Set history different from the default before getting the action
      // view since a call to MenuItem.getActionView() calls
      // ActionProvider.onCreateActionView() which uses the backing file name. Omit this
      // line if using the default share history file is desired.
      mShareActionProvider.setShareHistoryFileName("custom_share_history.xml");
      . . .
  }

  // Somewhere in the application.
  public void doShare(Intent shareIntent) {
      // When you want to share set the share intent.
      mShareActionProvider.setShareIntent(shareIntent);
  }
 

Note: While the sample snippet demonstrates how to use this provider in the context of a menu item, the use of the provider is not limited to menu items.

hasSubMenu in class ActionProvider

Returns:

true if the item backed by this provider should have an associated submenu

onPrepareSubMenu

public void onPrepareSubMenu(SubMenu subMenu)

Called to prepare an associated submenu for the menu item backed by this ActionProvider.

if ActionProvider.hasSubMenu() returns true, this method will be called when the menu item is selected to prepare the submenu for presentation to the user. Apps may use this to create or alter submenu content right before display.

Parameters:

subMenu - Submenu that will be displayed

Defaults to DEFAULT_SHARE_HISTORY_FILE_NAME. Set to null if share history should not be persisted between sessions.

Note: The history file name can be set any time, however only the action views created by onCreateActionView() after setting the file name will be backed by the provided file.

Parameters:

shareHistoryFile - The share history file name.
