AccessibilityNodeInfo.ExtraRenderingInfo

Kotlin |Java

public static final class AccessibilityNodeInfo.ExtraRenderingInfo
extends Object implements Parcelable

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 this information if it is available for this node.

Summary

Inherited constants

From interface android.os.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(Parcel, int)`: 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)`".

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 `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.
`void`	`writeToParcel(Parcel parcel, int flags)` Flatten this object in to a Parcel.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`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.
`final void`	`wait(long timeoutMillis)` 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.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

From interface


        
          android.os.Parcelable

`abstract int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`abstract void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

Public methods

describeContents

Added in API level 30

public int describeContents ()

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.

Returns
`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

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.

See also:

TypedValue.TYPE_DIMENSION

writeToParcel

Added in API level 30

public void writeToParcel (Parcel parcel, 
                int flags)

Flatten this object in to a Parcel.

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