Titanium.Android.ActionBar

Adds action items and sets several properties on a window's action bar in the XML and TSS files.

app/views/index.xml:

<Alloy>
    <Window title="My Test App">
        <ActionBar id="actionbar" title="My XML Menu" onHomeIconItemSelected="doMenuClick" />
        <Menu>
            <MenuItem id="item1" title="Settings" onClick="openSettings" />
            <MenuItem id="item2" title="Search" onClick="doSearch" />
        </Menu>
        <Label id="label">Welcome!</Label>
    </Window>
</Alloy>

app/controllers/index.js:

function doMenuClick() {}
function openSettings() {}
function doSearch() {}
$.index.open();

app/styles/index.tss:

"MenuItem": {
    showAsAction: Ti.Android.SHOW_AS_ACTION_ALWAYS
},
"#item1": {
    icon: Ti.Android.R.drawable.ic_menu_preferences
},
"#item2": {
    icon: Ti.Android.R.drawable.ic_menu_search
},
"#actionbar": {
    icon: "/actionicon.png",
    displayHomeAsUp: true,
    backgroundImage: "/actionbackground.png"
}

The following example sets several properties on a window's action bar.

const win = Ti.UI.createWindow({
    title: "Old Title",
    navBarHidden: false
});
if (OS_ANDROID) {
    win.activity.onCreate = () => {
        const actionBar = win.activity.actionBar;
        if (actionBar) {
            actionBar.backgroundImage = Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, 'bg.png').nativePath;
            actionBar.title = "New Title";
            actionBar.onHomeIconItemSelected = () => {
                Ti.API.info("Home icon clicked!");
            };
        }
    };
}
win.open();

The above can be done for a tab group via its activity property. Note that individual tab windows do not have an activity. Only the root tab group (which hosts the tabs) provides an activity property.
