Handling options menu - shiraji/androidannotations GitHub Wiki

Since AndroidAnnotations 2.2

You can easily add options menu support in your activities, with the @OptionsMenu and @OptionsItem annotations.

• @OptionsMenu lets you specify the menu resource to use
• @OptionsItem marks methods that receives menu selection events

Both annotations can be used independently.

Here is a simple example on how to use them:

@EActivity
@OptionsMenu(R.menu.my_menu)
public class MyActivity extends Activity {

	@OptionsMenuItem
	MenuItem menuSearch;

	@OptionsItem(R.id.menuShare)
	void myMethod() {
	  // You can specify the ID in the annotation, or use the naming convention
	}

	@OptionsItem
	void homeSelected() {
	  // home was selected in the action bar
	  // The "Selected" keyword is optional
	}

	@OptionsItem
	boolean menuSearch() {
	  menuSearch.setVisible(false);
	  // menuSearch was selected
	  // the return type may be void or boolean (false to allow normal menu processing to proceed, true to consume it here)
	  return true;
	}

	@OptionsItem({ R.id.menu_search, R.id.menu_delete })
	void multipleMenuItems() {
	  // You can specify multiple menu item IDs in @OptionsItem
	}

	@OptionsItem
	void menu_add(MenuItem item) {
	  // You can add a MenuItem parameter to access it
	}
}

Injecting Menu items

Since AndroidAnnotations 3.0

@OptionsMenuItem can be used to inject a MenuItem in an attribute.

Be careful : Injected menu items can't be used in @AfterInject nor @AfterViews annotated methods, because of Android activity lifecycle. More information are available here.

Inject Menu

Since AndroidAnnotations 4.0

With @InjectMenu you can inject the Fragment's or the Activity's Menu object.

Be careful : The menu also can't be used in @AfterInject nor @AfterViews as @OptionsMenuItem.

One example for the use:

@EActivity
public class MyActivity extends Activity {

	@InjectMenu
	Menu menu;
	
}

Multiple Options Menu

Since AndroidAnnotations 2.7

You can combine multiple xml menus with @OptionsMenu:

@EActivity
@OptionsMenu({R.menu.my_menu1, R.menu.my_menu2})
public class MyActivity extends Activity {

}

Fragment support

Since AndroidAnnotations 2.7

You can also use @OptionsMenu and @OptionsItem in Fragments:

@EFragment
@OptionsMenu(R.menu.my_fragment_menu)
public class MyFragment extends Fragment {

	@OptionsItem
	void menuRefreshSelected() {
	}
	
}
