public final class Size
extends Object

java.lang.Object
↳	android.util.Size

---

Immutable class for describing width and height dimensions in pixels.

Summary

Public constructors
Size(int width, int height) Create a new immutable Size instance.

Public methods
boolean	equals(Object obj) Check if this size is equal to another size.
int	getHeight() Get the height of the size (in pixels).
int	getWidth() Get the width of the size (in pixels).
int	hashCode() Returns a hash code value for the object.
static Size	parseSize(String string) Parses the specified string as a size value.
String	toString() Return the size represented as a string with the format "WxH"

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.

Public constructors

Size

Added in API level 21

public Size (int width, 
                int height)

Create a new immutable Size instance.

Parameters
width	int: The width of the size, in pixels
height	int: The height of the size, in pixels

Public methods

equals

Added in API level 21

public boolean equals (Object obj)

Check if this size is equal to another size.

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

A size object is never equal to any other type of object.

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

Returns
boolean	true if the objects were equal, false otherwise

getHeight

Added in API level 21

public int getHeight ()

Get the height of the size (in pixels).

Returns
int	height

getWidth

Added in API level 21

public int getWidth ()

Get the width of the size (in pixels).

Returns
int	width

hashCode

Added in API level 21

public int hashCode ()

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

Returns
int	a hash code value for this object.

parseSize

Added in API level 21

public static Size parseSize (String string)

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 Size s: Size.parseSize(s.toString()).equals(s). However, the method also handles sizes expressed in the following forms:

"widthxheight" or "width*height" => new Size(width, height), where width and height are string integers potentially containing a sign, such as "-10", "+7" or "5".

Size.parseSize("3*+6").equals(new Size(3, 6)) == true
 Size.parseSize("-3x-6").equals(new Size(-3, -6)) == true
 Size.parseSize("4 by 3") => throws NumberFormatException
 

Parameters
string	String: the string representation of a size value.

Returns
Size	the size value represented by string.

Throws
NumberFormatException	if string cannot be parsed as a size value.
NullPointerException	if string was null

toString

Added in API level 21

public String toString ()

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

Returns
String	string representation of the size
