ShareActionProvider

---

Kotlin |Java

public class ShareActionProvider
extends ActionProvider

java.lang.Object
↳	android.view.ActionProvider
	↳	android.widget.ShareActionProvider

---

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.

Constants

DEFAULT_SHARE_HISTORY_FILE_NAME

Added in API level 14

public static final String DEFAULT_SHARE_HISTORY_FILE_NAME

The default name for storing share history.

Constant Value: "share_history.xml"

Public constructors

ShareActionProvider

Added in API level 14

public ShareActionProvider (Context context)

Creates a new instance.

Parameters
context	Context: Context for accessing resources.

Public methods

hasSubMenu

Added in API level 14

public boolean hasSubMenu ()

Determines if this ActionProvider has a submenu associated with it.

Associated submenus will be shown when an action view is not. This provider instance will receive a call to onPrepareSubMenu(android.view.SubMenu) after the call to onPerformDefaultAction() and before a submenu is displayed to the user.

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

onCreateActionView

Added in API level 14

public View onCreateActionView ()

This method is deprecated.
use onCreateActionView(android.view.MenuItem)

Factory method called by the Android framework to create new action views.

This method has been deprecated in favor of onCreateActionView(android.view.MenuItem). Newer apps that wish to support platform versions prior to API 16 should also implement this method to return a valid action view.

Returns
View	A new action view. This value cannot be null.

onPrepareSubMenu

Added in API level 14

public void onPrepareSubMenu (SubMenu subMenu)

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

if 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: Submenu that will be displayed This value cannot be null.

setOnShareTargetSelectedListener

Added in API level 14

public void setOnShareTargetSelectedListener (ShareActionProvider.OnShareTargetSelectedListener listener)

Sets a listener to be notified when a share target has been selected. The listener can optionally decide to handle the selection and not rely on the default behavior which is to launch the activity.

Note: If you choose the backing share history file you will still be notified in this callback.

Parameters
listener	ShareActionProvider.OnShareTargetSelectedListener: The listener.

setShareHistoryFileName

Added in API level 14

public void setShareHistoryFileName (String shareHistoryFile)

Sets the file name of a file for persisting the share history which history will be used for ordering share targets. This file will be used for all view created by onCreateActionView(). 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. Therefore, if you want to use different history files for sharing specific types of content, every time you change the history file setShareHistoryFileName(java.lang.String) you must call Activity.invalidateOptionsMenu() to recreate the action view. You should not call Activity.invalidateOptionsMenu() from Activity.onCreateOptionsMenu(Menu).

 private void doShare(Intent intent) {
     if (IMAGE.equals(intent.getMimeType())) {
         mShareActionProvider.setHistoryFileName(SHARE_IMAGE_HISTORY_FILE_NAME);
     } else if (TEXT.equals(intent.getMimeType())) {
         mShareActionProvider.setHistoryFileName(SHARE_TEXT_HISTORY_FILE_NAME);
     }
     mShareActionProvider.setIntent(intent);
     invalidateOptionsMenu();
 }

Parameters
shareHistoryFile	String: The share history file name.

setShareIntent

Added in API level 14

public void setShareIntent (Intent shareIntent)

Sets an intent with information about the share action. Here is a sample for constructing a share intent:

 Intent shareIntent = new Intent(Intent.ACTION_SEND);
 shareIntent.setType("image/*");
 Uri uri = Uri.fromFile(new File(getFilesDir(), "foo.jpg"));
 shareIntent.putExtra(Intent.EXTRA_STREAM, uri);

Parameters
shareIntent	Intent: The share intent.
