PointerIcon
class PointerIcon : Parcelable
| kotlin.Any | |
| ↳ | android.view.PointerIcon |
Represents an icon that can be used as a mouse pointer.
Pointer icons can be provided either by the system using system types, or by applications using bitmaps or application resources.

create
static fun create(
bitmap: Bitmap,
hotSpotX: Float,
hotSpotY: Float
): PointerIcon
Creates a custom pointer icon from the given bitmap and hotspot information.
| Parameters | |
|---|---|
bitmap |
Bitmap: The bitmap for the icon. This value cannot be null. |
hotSpotX |
Float: The X offset of the pointer icon hotspot in the bitmap. Must be within the [0, bitmap.getWidth()) range. |
hotSpotY |
Float: The Y offset of the pointer icon hotspot in the bitmap. Must be within the [0, bitmap.getHeight()) range. |
| Return | |
|---|---|
PointerIcon |
A pointer icon for this bitmap. This value cannot be null. |
| Exceptions | |
|---|---|
java.lang.IllegalArgumentException |
if bitmap is null, or if the x/y hotspot parameters are invalid. |
describeContents
fun describeContents(): Int
| 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 |
equals
fun equals(other: Any?): Boolean
Indicates whether some other object is "equal to" this one.
The equals method implements an equivalence relation on non-null object references:
- It is reflexive: for any non-null reference value
x,x.equals(x)should returntrue. - It is symmetric: for any non-null reference values
xandy,x.equals(y)should returntrueif and only ify.equals(x)returnstrue. - It is transitive: for any non-null reference values
x,y, andz, ifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue. - It is consistent: for any non-null reference values
xandy, multiple invocations ofx.equals(y)consistently returntrueor consistently returnfalse, provided no information used inequalscomparisons on the objects is modified. - For any non-null reference value
x,x.equals(null)should returnfalse.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
| Parameters | |
|---|---|
obj |
the reference object with which to compare. |
other |
Any?: This value may be null. |
| Return | |
|---|---|
Boolean |
true if this object is the same as the obj argument; false otherwise. |
getSystemIcon
static fun getSystemIcon(
context: Context,
type: Int
): PointerIcon
Gets a system pointer icon for the given type.
| Parameters | |
|---|---|
context |
Context: The context. This value cannot be null. |
type |
Int: The pointer icon type. |
| Return | |
|---|---|
PointerIcon |
The pointer icon. This value cannot be null. |
| Exceptions | |
|---|---|
java.lang.IllegalArgumentException |
if context is null. |
load
static fun load(
resources: Resources,
resourceId: Int
): PointerIcon
Loads a custom pointer icon from an XML resource.
The XML resource should have the following form: <?xml version="1.0" encoding="utf-8"?> <pointer-icon xmlns:android="http://schemas.android.com/apk/res/android" android:bitmap="@drawable/my_pointer_bitmap" android:hotSpotX="24" android:hotSpotY="24" />
| Parameters | |
|---|---|
resources |
Resources: The resources object. This value cannot be null. |
resourceId |
Int: The resource id. |
| Return | |
|---|---|
PointerIcon |
The pointer icon. This value cannot be null. |
| Exceptions | |
|---|---|
java.lang.IllegalArgumentException |
if resources is null. |
android.content.res.Resources.NotFoundException |
if the resource was not found or the drawable linked in the resource was not found. |
toString
fun toString(): String
| Return | |
|---|---|
String |
a string representation of the object. |
writeToParcel
fun writeToParcel(
out: Parcel,
flags: Int
): Unit
| 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 android.os.Parcelable#PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
