Kotlin |Java

public static final class AccessibilityNodeInfo.ExtraRenderingInfo
extends Object

java.lang.Object
↳	android.view.accessibility.AccessibilityNodeInfo.ExtraRenderingInfo

Class with information of a view useful to evaluate accessibility needs. Developers can refresh the node with the key AccessibilityNodeInfo.EXTRA_DATA_RENDERING_INFO_KEY to fetch the text size and unit if it is TextView and the height and the width of layout params from ViewGroup or TextView.

`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.

`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

Public methods

getLayoutSize

Added in API level 30

public Size getLayoutSize ()

Gets the size object containing the height and the width of ViewGroup.LayoutParams if the node is a ViewGroup or a TextView, or null otherwise. Useful for some accessibility services to understand whether the text is scalable and fits the view or not.

Returns
`Size`	a `Size` stores layout height and layout width of the view, or null otherwise. And the size value may be in pixels, `ViewGroup.LayoutParams.MATCH_PARENT`, or `ViewGroup.LayoutParams.WRAP_CONTENT`

getTextSizeInPx

Added in API level 30

public float getTextSizeInPx ()

Gets the text size if the node is a TextView, or -1 otherwise. Useful for some accessibility services to understand whether the text is scalable and fits the view or not.

Returns
`float`	the text size of a `TextView`, or -1 otherwise.

getTextSizeUnit

Added in API level 30

public int getTextSizeUnit ()

Gets the text size unit if the node is a TextView, or -1 otherwise. Text size returned from getTextSizeInPx() in raw pixels may scale by factors and convert from other units. Useful for some accessibility services to understand whether the text is scalable and fits the view or not.

Returns
`int`	the text size unit which type is `TypedValue.TYPE_DIMENSION` of a `TextView`, or -1 otherwise.
