ToolbarAndroid
ToolbarAndroid
React component that wraps the Android-only Toolbar
widget. A Toolbar can display a logo, navigation icon (e.g. hamburger menu), a title & subtitle and a list of actions. The title and subtitle are expanded so the logo and navigation icons are displayed on the left, title and subtitle in the middle and the actions on the right.
If the toolbar has an only child, it will be displayed between the title and actions.
Although the Toolbar supports remote images for the logo, navigation and action icons, this should only be used in DEV mode where require('./some_icon.png')
translates into a packager URL. In release mode you should always use a drawable resource for these icons. Using require('./some_icon.png')
will do this automatically for you, so as long as you don't explicitly use e.g. {uri: 'http://...'}
, you will be good.
Example:
render: function() { return ( <ToolbarAndroid logo={require('./app_logo.png')} title="AwesomeApp" actions={[{title: 'Settings', icon: require('./icon_settings.png'), show: 'always'}]} onActionSelected={this.onActionSelected} /> ) }, onActionSelected: function(position) { if (position === 0) { // index of 'Settings' showSettings(); } }
Props
ViewPropTypes props...
actions?: PropTypes.arrayOf(PropTypes.shape({ title: PropTypes.string.isRequired, icon: optionalImageSource, show: PropTypes.oneOf(['always', 'ifRoom', 'never']), showWithText: PropTypes.bool }))
Sets possible actions on the toolbar as part of the action menu. These are displayed as icons or text on the right side of the widget. If they don't fit they are placed in an 'overflow' menu.
This property takes an array of objects, where each object has the following keys:
-
title
: required, the title of this action -
icon
: the icon for this action, e.g.require('./some_icon.png')
-
show
: when to show this action as an icon or hide it in the overflow menu:always
,ifRoom
ornever
-
showWithText
: boolean, whether to show text alongside the icon or not
contentInsetEnd?: PropTypes.number
Sets the content inset for the toolbar ending edge.
The content inset affects the valid area for Toolbar content other than the navigation button and menu. Insets define the minimum margin for these components and can be used to effectively align Toolbar content along well-known gridlines.
contentInsetStart?: PropTypes.number
Sets the content inset for the toolbar starting edge.
The content inset affects the valid area for Toolbar content other than the navigation button and menu. Insets define the minimum margin for these components and can be used to effectively align Toolbar content along well-known gridlines.
logo?: optionalImageSource

onIconClicked?: PropTypes.func

rtl?: PropTypes.bool
Used to set the toolbar direction to RTL. In addition to this property you need to add

to your application AndroidManifest.xml and then call setLayoutDirection(LayoutDirection.RTL)
in your MainActivity onCreate
method.
