SizeF

class SizeF : Parcelable
kotlin.Any
   ↳ android.util.SizeF

Immutable class for describing width and height dimensions in some arbitrary unit.

Width and height are finite values stored as a floating point representation.

Summary

Inherited constants
Public constructors
SizeF(width: Float, height: Float)

Create a new immutable SizeF instance.
Public methods
Int

Parcelable interface methods
Boolean
equals(other: Any?)

Check if this size is equal to another size.
Float

Get the height of the size (as an arbitrary unit).
Float

Get the width of the size (as an arbitrary unit).
Int

Returns a hash code value for the object.
static SizeF!
parseSizeF(string: String!)

Parses the specified string as a size value.
String

Return the size represented as a string with the format "WxH"
Unit
writeToParcel(out: Parcel, flags: Int)

Write this size to the specified parcel.
Properties

Public constructors

SizeF

Added in API level 21
SizeF(
    width: Float, 
    height: Float)

Create a new immutable SizeF instance.

Both the width and the height must be a finite number. In particular, NaN and positive/negative infinity are illegal values.

Parameters
width Float: The width of the size
height Float: The height of the size
Exceptions
java.lang.IllegalArgumentException if either width or height was not finite.

Public methods

describeContents

Added in API level 31
fun describeContents(): Int

Parcelable interface methods

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

Added in API level 21
fun equals(other: Any?): Boolean

Check if this size is equal to another size.

Two sizes are equal if and only if both their widths and heights are the same.

For this purpose, the width/height float values are considered to be the same if and only if the method Float.floatToIntBits(float) returns the identical int value when applied to each.

Parameters
obj the reference object with which to compare.
Return
Boolean true if the objects were equal, false otherwise

getHeight

Added in API level 21
fun getHeight(): Float

Get the height of the size (as an arbitrary unit).

Return
Float height

getWidth

Added in API level 21
fun getWidth(): Float

Get the width of the size (as an arbitrary unit).

Return
Float width

hashCode

Added in API level 21
fun hashCode(): Int

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Return
Int a hash code value for this object.

parseSizeF

Added in API level 21
static fun parseSizeF(string: String!): SizeF!

Parses the specified string as a size value.

The ASCII characters \u002a ('*') and \u0078 ('x') are recognized as separators between the width and height.

For any SizeF s: SizeF.parseSizeF(s.toString()).equals(s). However, the method also handles sizes expressed in the following forms:

"widthxheight" or "width*height" => new SizeF(width, height), where width and height are string floats potentially containing a sign, such as "-10.3", "+7" or "5.2", but not containing an 'x' (such as a float in hexadecimal string format).

<code>SizeF.parseSizeF("3.2*+6").equals(new SizeF(3.2f, 6.0f)) == true
  SizeF.parseSizeF("-3x-6").equals(new SizeF(-3.0f, -6.0f)) == true
  SizeF.parseSizeF("4 by 3") =&gt; throws NumberFormatException
  </code>
Parameters
string String!: the string representation of a size value.
Return
SizeF! the size value represented by string.
Exceptions
java.lang.NumberFormatException if string cannot be parsed as a size value.
java.lang.NullPointerException if string was null

toString

Added in API level 21
fun toString(): String

Return the size represented as a string with the format "WxH"

Return
String string representation of the size

writeToParcel

Added in API level 31
fun writeToParcel(
    out: Parcel, 
    flags: Int
): Unit

Write this size to the specified parcel. To restore a size from a parcel, use the CREATOR.

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
out Parcel: The parcel to write the point's coordinates into This value cannot be null.

Properties

CREATOR
