AccessibilityNodeInfo.TouchDelegateInfo

Kotlin |Java

public static final class AccessibilityNodeInfo.TouchDelegateInfo
extends Object implements Parcelable

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

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

AccessibilityNodeInfo.setTouchDelegateInfo(TouchDelegateInfo)

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)`".

Fields
`public static final Creator<AccessibilityNodeInfo.TouchDelegateInfo>`	`CREATOR`

Public constructors
`TouchDelegateInfo(Map<Region, View> targetMap)` 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(int index)` 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`.
`void`	`writeToParcel(Parcel dest, 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.

Fields

CREATOR

Added in API level 29

public static final Creator<AccessibilityNodeInfo.TouchDelegateInfo> CREATOR

See also:

Parcelable.Creator

Public constructors

TouchDelegateInfo

Added in API level 29

public TouchDelegateInfo (Map<Region, View> targetMap)

Create a new instance of TouchDelegateInfo.

Parameters
`targetMap`	`Map`: A map from regions (in view coordinates) to delegated views. This value cannot be `null`.

Throws
`IllegalArgumentException`	if targetMap is empty or `null` in Regions or Views.

Public methods

describeContents

Added in API level 29

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`

getRegionAt

Added in API level 29

public Region getRegionAt (int index)

Return the Region at the given index in the TouchDelegateInfo.

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

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

getRegionCount

Added in API level 29

public int getRegionCount ()

Returns the number of touch delegate target region.

Returns
`int`	Number of touch delegate target region.

getTargetForRegion

Added in API level 29

public AccessibilityNodeInfo getTargetForRegion (Region region)

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`.

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

writeToParcel

Added in API level 29

public void writeToParcel (Parcel dest, 
                int flags)

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.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
