View
is the fundamental UI building block. It is a component that supports
style, layout with flexbox, and accessibility controls. It can be nested
inside another View
and has 0-to-many children of any type.
Unsupported React Native props:
accessibilityComponentType
(android) – use accessibilityRole
,
accessibilityTraits
(ios) – use accessibilityRole
,
collapsable
(android),
importantForAccessibility
(android),
needsOffscreenAlphaCompositing
(android),
onAccessibilityTap
,
onMagicTap
,
onMoveShouldSetResponder
,
onResponder*
,
onStartShouldSetResponder
,
onStartShouldSetResponderCapture
removeClippedSubviews
(ios),
renderToHardwareTextureAndroid
(android),
shouldRasterizeIOS
(ios)
NOTE: View
will transfer all other props to the rendered HTML element.
accessibilityLabel: string
Defines the text available to assistive technologies upon interaction with the
element. (This is implemented using aria-label
.)
accessibilityLiveRegion: oneOf('assertive', 'off', 'polite') = 'off'
Indicates to assistive technologies whether to notify the user when the view
changes. The values of this attribute are expressed in degrees of importance.
When regions are specified as polite
(recommended), updates take low
priority. When regions are specified as assertive
, assistive technologies
will interrupt and immediately notify the user. (This is implemented using
aria-live
.)
(web) accessibilityRole: oneOf(roles)
Allows assistive technologies to present and support interaction with the view
in a manner that is consistent with user expectations for similar views of that
type. For example, marking a touchable view with an accessibilityRole
of
button
. (This is implemented using ARIA roles).
Note: Avoid changing accessibilityRole
values over time or after user
actions. Generally, accessibility APIs do not provide a means of notifying
assistive technologies of a role
value change.
accessible: bool = true
When false
, the view is hidden from assistive technologies. (This is
implemented using aria-hidden
.)
(web) component: function | string = 'div'
The React Component for this view.
onLayout: function
(TODO)
pointerEvents: oneOf('auto', 'box-only', 'box-none', 'none') = 'auto'
Configure the pointerEvents
of the view. The enhanced pointerEvents
modes
provided are not part of the CSS spec, therefore, pointerEvents
is excluded
from style
.
box-none
is the equivalent of:
.box-none { pointer-events: none }
.box-none * { pointer-events: auto }
box-only
is the equivalent of:
.box-only { pointer-events: auto }
.box-only * { pointer-events: none }
