TouchDelegateInfo

Kotlin |Java

class TouchDelegateInfo : Parcelable

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

Class with information of touch delegated views and regions from TouchDelegate for the AccessibilityNodeInfo.

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 constructors
`TouchDelegateInfo(targetMap: MutableMap<Region!, View!>)` Create a new instance of `TouchDelegateInfo`.

Public methods
Int	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
Region	`getRegionAt(index: Int)` Return the `Region` at the given index in the `TouchDelegateInfo`.
Int	`getRegionCount()` Returns the number of touch delegate target region.
AccessibilityNodeInfo?	`getTargetForRegion(region: Region)` Return the target `AccessibilityNodeInfo` for the given `Region`.
Unit	`writeToParcel(dest: Parcel, flags: Int)` Flatten this object in to a Parcel.

Properties

Public constructors

TouchDelegateInfo

Added in API level 29

TouchDelegateInfo(targetMap: MutableMap<Region!, View!>)

Create a new instance of TouchDelegateInfo.

Parameters
`targetMap`	MutableMap<Region!, View!>: A map from regions (in view coordinates) to delegated views. This value cannot be `null`.

Exceptions
`java.lang.IllegalArgumentException`	if targetMap is empty or `null` in Regions or Views.

Public methods

describeContents

Added in API level 29

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 `android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR`

getRegionAt

Added in API level 29

fun getRegionAt(index: Int): Region

Return the Region at the given index in the TouchDelegateInfo.

Parameters
`index`	Int: The desired index, must be between 0 and `getRegionCount()`-1.

Return
`Region`	Returns the `Region` stored at the given index. This value cannot be `null`.

getRegionCount

Added in API level 29

fun getRegionCount(): Int

Returns the number of touch delegate target region.

Return
`Int`	Number of touch delegate target region.

getTargetForRegion

Added in API level 29

fun getTargetForRegion(region: Region): AccessibilityNodeInfo?

Return the target AccessibilityNodeInfo for the given Region.

Note: This api can only be called from AccessibilityService.

Parameters
`region`	Region: The region retrieved from `getRegionAt(int)`. This value cannot be `null`.

Return
`AccessibilityNodeInfo?`	The target node associates with the given region. This value may be `null`.

writeToParcel

Added in API level 29

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

Flatten this object in to a Parcel.

Parameters
`dest`	Parcel: 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 `android.os.Parcelable#PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES

Properties

CREATOR

Added in API level 29

static val CREATOR: Parcelable.Creator<AccessibilityNodeInfo.TouchDelegateInfo!>
