Fields

CREATOR

added in API level 24
Creator<PointerIcon> CREATOR

Public methods

create

added in API level 24
PointerIcon create (Bitmap bitmap, 
                float hotSpotX, 
                float hotSpotY)

Creates a custom pointer icon from the given bitmap and hotspot information.

Parameters
bitmap Bitmap: The bitmap for the icon.

This value must never 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.

Returns
PointerIcon A pointer icon for this bitmap.

Throws
IllegalArgumentException if bitmap is null, or if the x/y hotspot parameters are invalid.

describeContents

added in API level 24
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(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.

equals

added in API level 24
boolean equals (Object other)

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 return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Parameters
other Object: the reference object with which to compare.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

getSystemIcon

added in API level 24
PointerIcon getSystemIcon (Context context, 
                int type)

Gets a system pointer icon for the given type. If typeis not recognized, returns the default pointer icon.

Parameters
context Context: The context.

This value must never be null.

type int: The pointer icon type.

Returns
PointerIcon The pointer icon.

Throws
IllegalArgumentException if context is null.

load

added in API level 24
PointerIcon load (Resources resources, 
                int resourceId)

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 must never be null.

resourceId int: The resource id.

Returns
PointerIcon The pointer icon.

Throws
IllegalArgumentException if resources is null.
if the resource was not found or the drawable linked in the resource was not found.

writeToParcel

added in API level 24
void writeToParcel (Parcel out, 
                int flags)

Flatten this object in to a Parcel.

Parameters
out Parcel: The Parcel in which the object should be written.

flags int: Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
