ExtraRenderingInfo

Kotlin |Java

class ExtraRenderingInfo : Parcelable

kotlin.Any
↳	android.view.accessibility.AccessibilityNodeInfo.ExtraRenderingInfo

Class with information of a view useful to evaluate accessibility needs. Developers can refresh the node with the key EXTRA_DATA_RENDERING_INFO_KEY to fetch this information if it is available for this node.

Summary

Inherited constants

From class Parcelable

Int

CONTENTS_FILE_DESCRIPTOR

Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.

Int

PARCELABLE_WRITE_RETURN_VALUE

Flag for use with writeToParcel: the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)". Some implementations may want to release resources at this point.

Public methods
Int	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
Size?	`getLayoutSize()` Gets the size object containing the height and the width of `android.view.ViewGroup.LayoutParams` if the node is a `ViewGroup` or a `TextView`, or null otherwise.
Float	`getTextSizeInPx()` Gets the text size if the node is a `TextView`, or -1 otherwise.
Int	`getTextSizeUnit()` Gets the text size unit if the node is a `TextView`, or -1 otherwise.
Unit	`writeToParcel(parcel: Parcel, flags: Int)` Flatten this object in to a Parcel.

Public methods

describeContents

Added in API level 30

fun describeContents(): Int

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel,int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Return
`Int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

getLayoutSize

Added in API level 30

fun getLayoutSize(): Size?

Gets the size object containing the height and the width of android.view.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.

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

getTextSizeInPx

Added in API level 30

fun getTextSizeInPx(): Float

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.

Return
`Float`	the text size of a `TextView`, or -1 otherwise.

getTextSizeUnit

Added in API level 30

fun getTextSizeUnit(): Int

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.

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

writeToParcel

Added in API level 30

fun writeToParcel(
    parcel: Parcel, 
    flags: Int
): Unit

Flatten this object in to a Parcel.

Parameters
`dest`	The Parcel in which the object should be written. This value cannot be `null`.
`flags`	Int: Additional flags about how the object should be written. May be 0 or `PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of the following: `PARCELABLE_WRITE_RETURN_VALUE`
`parcel`	Parcel: This value cannot be `null`.
