## Fields
### CREATOR
Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static final Creator CREATOR
```
## Public constructors
### SizeF
Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public SizeF (float width,
float height)
```
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
|
| Throws ||
|---|---|
| `https://developer.android.com/reference/java/lang/IllegalArgumentException` | if either `width` or `height` was not finite. |
## Public methods
### describeContents
Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public int describeContents ()
```
Parcelable interface methods
| Returns ||
|---|---|
| `int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or - `https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` |
### equals
Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
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 the same.
For this purpose, the width/height float values are considered to be the same if and only if the method `https://developer.android.com/reference/java/lang/Float#floatToIntBits(float)` returns the identical `int` value when applied to each.
| 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](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public float getHeight ()
```
Get the height of the size (as an arbitrary unit).
| Returns ||
|---|---|
| `float` | height
|
### getWidth
Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public float getWidth ()
```
Get the width of the size (as an arbitrary unit).
| Returns ||
|---|---|
| `float` | width
|
### hashCode
Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
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 `https://developer.android.com/reference/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 `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` 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 `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` 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.
|
### parseSizeF
Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static SizeF parseSizeF (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 `SizeF s`: `SizeF.parseSizeF(s.toString()).equals(s)`. However, the method also handles sizes expressed in the following forms:
"*width*`x`*height*" 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).
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") => throws NumberFormatException
| Parameters ||
|---|---|
| `string` | `String`: the string representation of a size value.
|
| Returns ||
|---|---|
| `https://developer.android.com/reference/android/util/SizeF` | the size value represented by `string`.
|
| Throws ||
|---|---|
| `https://developer.android.com/reference/java/lang/NullPointerException` | if `string` was `null` |
| `https://developer.android.com/reference/java/lang/NumberFormatException` | if `string` cannot be parsed as a size value. |
### toString
Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public String toString ()
```
Return the size represented as a string with the format `"WxH"`
| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | string representation of the size
|
### writeToParcel
Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void writeToParcel (Parcel out,
int flags)
```
Write this size to the specified parcel. To restore a size from a parcel, use the `https://developer.android.com/reference/android/util/SizeF#CREATOR`.
| Parameters ||
|---|---|
| `out` | `Parcel`: The parcel to write the point's coordinates into. This value cannot be `null`.
|
| `flags` | `int`: Additional flags about how the object should be written. May be 0 or `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE` |
