从xml和每个片段充气sherlock动作栏菜单

Question

我正在我的主要活动中创建操作栏菜单:

public boolean onCreateOptionsMenu(Menu menu) {
    // Used to put dark icons on light action bar
    SubMenu sub = menu.addSubMenu(null);
    sub.add(0, R.style.Theme_Sherlock, 0, "Default");
    sub.add(0, R.style.Theme_Sherlock_Light, 0, "Light");
    sub.add(0, R.style.Theme_Sherlock_Light_DarkActionBar, 0,
            "Light (Dark Action Bar)");

    MenuItem ShareButton = sub.getItem();
    ShareButton.setIcon(R.drawable.ic_action_overflow);
    ShareButton.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS
            | MenuItem.SHOW_AS_ACTION_WITH_TEXT);

    return true;

}

然后在我的片段活动中,我尝试更改第二个片段的菜单:

first i do this:
 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setHasOptionsMenu(true);
    }

我这样做:

@Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        // TODO Auto-generated method stub
        //final MenuInflater inflater2 = getMenuInflater();
        //inflater.inflate(R.menu.historymenu, menu);
        Log.v("Some Log", "I'm in on Create Options Menu");

        SubMenu sub = menu.addSubMenu(null);
        sub.add(0, R.style.Theme_Sherlock, 0, "HistoryCheck");


        MenuItem ShareButton = sub.getItem();
        ShareButton.setIcon(R.drawable.ic_action_overflow);
        ShareButton.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS
                | MenuItem.SHOW_AS_ACTION_WITH_TEXT);

        super.onCreateOptionsMenu(menu, inflater);
    }

正如你所看到的,我很乐意为.xml为每个片段和主要活动提供菜单,但由于某些原因,通货膨胀什么都不做.

使用代码添加新的子菜单,当我切换到第二个标签/片段时,我得到2个菜单,我想更改现有菜单,而不是添加额外的菜单.

请帮我改变正确的路线.

如果您想要更改菜单,请不要在主活动中添加菜单,只在片段中添加菜单.这样切换片段时,菜单会相应切换.

您CAN膨胀从XML的菜单:

@Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        super.onCreateOptionsMenu(menu, inflater);
        inflater.inflate(R.menu.the_menu, menu);
    }

只要确保你导入com.actionbarsherlock.view.Menu和com.actionbarsherlock.view.MenuInflater.

the_menu.xml(带子菜单)

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@+id/menu_item"
        android:showAsAction="always"
        android:title="Menu">
        <menu>
            <item
                android:id="@+id/submenu_1"
                android:showAsAction="always"
                android:title="submenu 1"/>
            <item
                android:id="@+id/submenu_2"
                android:showAsAction="always"
                android:title="submenu 2"/>
        </menu>
    </item>

</menu>
