Properties

accessibilityActions?: readonly Readonly<{ label?: string; name: string }>[]

Provides an array of custom actions available for accessibility.

accessibilityElementsHidden?: boolean

A Boolean value indicating whether the accessibility elements contained within this accessibility element are hidden to the screen reader.

platform

ios

accessibilityHint?: string

An accessibility hint helps users understand what will happen when they perform an action on the accessibility element when that result is not obvious from the accessibility label.

accessibilityIgnoresInvertColors?: boolean
accessibilityLabel?: string

Overrides the text that's read by the screen reader when the user interacts with the element. By default, the label is constructed by traversing all the children and accumulating all the Text nodes separated by space.

accessibilityLiveRegion?: "none" | "polite" | "assertive"

Indicates to accessibility services whether the user should be notified when this view changes. Works for Android API >= 19 only. See http://developer.android.com/reference/android/view/View.html#attr_android:accessibilityLiveRegion for references.

platform

android

accessibilityRole?: AccessibilityRole

Accessibility Role tells a person using either VoiceOver on iOS or TalkBack on Android the type of element that is focused on.

accessibilityState?: AccessibilityState

Accessibility State tells a person using either VoiceOver on iOS or TalkBack on Android the state of the element currently focused on.

accessibilityValue?: AccessibilityValue

Represents the current value of a component. It can be a textual description of a component's value, or for range-based components, such as sliders and progress bars, it contains range information (minimum, current, and maximum).

accessibilityViewIsModal?: boolean

A Boolean value indicating whether VoiceOver should ignore the elements within views that are siblings of the receiver.

platform

ios

accessible?: boolean

When true, indicates that the view is an accessibility element. By default, all the touchable elements are accessible.

android_zOrderMediaOverlay?: boolean
children?: ReactNode
collapsable?: boolean

Views that are only used to layout their children or otherwise don't draw anything may be automatically removed from the native hierarchy as an optimization. Set this property to false to disable this optimization and ensure that this View exists in the native view hierarchy.

focusable?: boolean

Whether this View should be focusable with a non-touch input device, eg. receive focus with a hardware keyboard.

hasTVPreferredFocus?: boolean

(Apple TV only) May be set to true to force the Apple TV focus engine to move focus to this view.

platform

ios

hitSlop?: Insets

This defines how far a touch event can start away from the view. Typical interface guidelines recommend touch targets that are at least 30 - 40 points/density-independent pixels. If a Touchable view has a height of 20 the touchable height can be extended to 40 with hitSlop={{top: 10, bottom: 10, left: 0, right: 0}} NOTE The touch area never extends past the parent view bounds and the Z-index of sibling views always takes precedence if a touch hits two overlapping views.

importantForAccessibility?: "auto" | "yes" | "no" | "no-hide-descendants"

Controls how view is important for accessibility which is if it fires accessibility events and if it is reported to accessibility services that query the screen. Works for Android only. See http://developer.android.com/reference/android/R.attr.html#importantForAccessibility for references.

Possible values: 'auto' - The system determines whether the view is important for accessibility - default (recommended). 'yes' - The view is important for accessibility. 'no' - The view is not important for accessibility. 'no-hide-descendants' - The view is not important for accessibility, nor are any of its descendant views.

isTVSelectable?: boolean

(Apple TV only) When set to true, this view will be focusable and navigable using the Apple TV remote.

platform

ios

mirror?: boolean
nativeID?: string

Used to reference react managed views from native code.

needsOffscreenAlphaCompositing?: boolean

Whether this view needs to rendered offscreen and composited with an alpha in order to preserve 100% correct colors and blending behavior. The default (false) falls back to drawing the component and its children with an alpha applied to the paint used to draw each element instead of rendering the full component offscreen and compositing it back with an alpha value. This default may be noticeable and undesired in the case where the View you are setting an opacity on has multiple overlapping elements (e.g. multiple overlapping Views, or text and a background).

Rendering offscreen to preserve correct alpha behavior is extremely expensive and hard to debug for non-native developers, which is why it is not turned on by default. If you do need to enable this property for an animation, consider combining it with renderToHardwareTextureAndroid if the view contents are static (i.e. it doesn't need to be redrawn each frame). If that property is enabled, this View will be rendered off-screen once, saved in a hardware texture, and then composited onto the screen with an alpha each frame without having to switch rendering targets on the GPU.

onAccessibilityAction?: ((event: AccessibilityActionEvent) => void)

Type declaration

    • (event: AccessibilityActionEvent): void
    • When accessible is true, the system will try to invoke this function when the user performs an accessibility custom action.

      Parameters

      • event: AccessibilityActionEvent

      Returns void

onAccessibilityEscape?: (() => void)

Type declaration

    • (): void
    • When accessibile is true, the system will invoke this function when the user performs the escape gesture (scrub with two fingers).

      platform

      ios

      Returns void

onAccessibilityTap?: (() => void)

Type declaration

    • (): void
    • When accessible is true, the system will try to invoke this function when the user performs accessibility tap gesture.

      platform

      ios

      Returns void

onLayout?: ((event: LayoutChangeEvent) => void)

Type declaration

    • (event: LayoutChangeEvent): void
    • Invoked on mount and layout changes with

      {nativeEvent: { layout: {x, y, width, height}}}.

      Parameters

      • event: LayoutChangeEvent

      Returns void

onMagicTap?: (() => void)

Type declaration

    • (): void
    • When accessible is true, the system will invoke this function when the user performs the magic tap gesture.

      platform

      ios

      Returns void

onMoveShouldSetResponder?: ((event: GestureResponderEvent) => boolean)

Type declaration

    • (event: GestureResponderEvent): boolean
    • Called for every touch move on the View when it is not the responder: does this view want to "claim" touch responsiveness?

      Parameters

      • event: GestureResponderEvent

      Returns boolean

onMoveShouldSetResponderCapture?: ((event: GestureResponderEvent) => boolean)

Type declaration

    • (event: GestureResponderEvent): boolean
    • onStartShouldSetResponder and onMoveShouldSetResponder are called with a bubbling pattern, where the deepest node is called first. That means that the deepest component will become responder when multiple Views return true for *ShouldSetResponder handlers. This is desirable in most cases, because it makes sure all controls and buttons are usable.

      However, sometimes a parent will want to make sure that it becomes responder. This can be handled by using the capture phase. Before the responder system bubbles up from the deepest component, it will do a capture phase, firing on*ShouldSetResponderCapture. So if a parent View wants to prevent the child from becoming responder on a touch start, it should have a onStartShouldSetResponderCapture handler which returns true.

      Parameters

      • event: GestureResponderEvent

      Returns boolean

onResponderEnd?: ((event: GestureResponderEvent) => void)

Type declaration

    • (event: GestureResponderEvent): void
    • If the View returns true and attempts to become the responder, one of the following will happen:

      Parameters

      • event: GestureResponderEvent

      Returns void

onResponderGrant?: ((event: GestureResponderEvent) => void)

Type declaration

    • (event: GestureResponderEvent): void
    • The View is now responding for touch events. This is the time to highlight and show the user what is happening

      Parameters

      • event: GestureResponderEvent

      Returns void

onResponderMove?: ((event: GestureResponderEvent) => void)

Type declaration

    • (event: GestureResponderEvent): void
    • The user is moving their finger

      Parameters

      • event: GestureResponderEvent

      Returns void

onResponderReject?: ((event: GestureResponderEvent) => void)

Type declaration

    • (event: GestureResponderEvent): void
    • Something else is the responder right now and will not release it

      Parameters

      • event: GestureResponderEvent

      Returns void

onResponderRelease?: ((event: GestureResponderEvent) => void)

    • (event: GestureResponderEvent): void
    • Parameters

      • event: GestureResponderEvent

      Returns void

onResponderTerminate?: ((event: GestureResponderEvent) => void)

Type declaration

    • (event: GestureResponderEvent): void
    • The responder has been taken from the View. Might be taken by other views after a call to onResponderTerminationRequest, or might be taken by the OS without asking (happens with control center/ notification center on iOS)

participant?: Participant
pointerEvents?: "box-none" | "none" | "box-only" | "auto"

In the absence of auto property, none is much like CSS's none value. box-none is as if you had applied the CSS class:

.box-none { pointer-events: none; } .box-none * { pointer-events: all; }

box-only is the equivalent of

.box-only { pointer-events: all; } .box-only * { pointer-events: none; }

But since pointerEvents does not affect layout/appearance, and we are already deviating from the spec by adding additional modes, we opt to not include pointerEvents on style. On some platforms, we would need to implement it as a className anyways. Using style or not is an implementation detail of the platform.

removeClippedSubviews?: boolean

This is a special performance property exposed by RCTView and is useful for scrolling content when there are many subviews, most of which are offscreen. For this property to be effective, it must be applied to a view that contains many subviews that extend outside its bound. The subviews must also have overflow: hidden, as should the containing view (or one of its superviews).

renderToHardwareTextureAndroid?: boolean

Whether this view should render itself (and all of its children) into a single hardware texture on the GPU.

On Android, this is useful for animations and interactions that only modify opacity, rotation, translation, and/or scale: in those cases, the view doesn't have to be redrawn and display lists don't need to be re-executed. The texture can just be re-used and re-composited with different parameters. The downside is that this can use up limited video memory, so this prop should be set back to false at the end of the interaction/animation.

resizeMode?: "contain" | "cover" | "center"
roomId?: string
shouldRasterizeIOS?: boolean

Whether this view should be rendered as a bitmap before compositing.

On iOS, this is useful for animations and interactions that do not modify this component's dimensions nor its children; for example, when translating the position of a static view, rasterization allows the renderer to reuse a cached bitmap of a static view and quickly composite it during each frame.

Rasterization incurs an off-screen drawing pass and the bitmap consumes memory. Test and measure when using this property.

style?: StyleProp<ViewStyle>
testID?: string

Used to locate this view in end-to-end tests.
