BiometricPromptStyleSpec

Kotlin |Java

public final class BiometricPromptStyleSpec
extends Object implements Parcelable

java.lang.Object
↳	android.hardware.biometrics.BiometricPromptStyleSpec

A class that describes the visual styles of the embedded BiometricPrompt UI to allow client applications to maintain visual consistency. This includes background color, font family, dimensions, etc.

These style values are supplied by the system to the client application. The dimensional values (width, height, corner radius) are in pixels (px) and are scaled for the density of the display where the biometric prompt is displayed.

Inherited constants

From interface android.os.Parcelable

`int`	`CONTENTS_FILE_DESCRIPTOR` Descriptor bit used with `describeContents()`: indicates that the Parcelable object's flattened representation includes a file descriptor.

Fields
`public static final Creator<BiometricPromptStyleSpec>`	`CREATOR`

Public constructors
`BiometricPromptStyleSpec(int backgroundColor, int width, int height, int cornerRadius)`

Public methods
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`boolean`	`equals(Object o)` Indicates whether some other object is "equal to" this one.
`int`	`getBackgroundColor()`
`int`	`getCornerRadius()`
`int`	`getHeight()`
`int`	`getWidth()`
`int`	`hashCode()` Returns a hash code value for the object.
`void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

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.

From interface


        
          android.os.Parcelable

`abstract int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`abstract void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

Fields

CREATOR

Added in version 37.2

public static final Creator<BiometricPromptStyleSpec> CREATOR

Public constructors

BiometricPromptStyleSpec

Added in version 37.2

public BiometricPromptStyleSpec (int backgroundColor, 
                int width, 
                int height, 
                int cornerRadius)

Parameters
`backgroundColor`	`int`: The background color for BiometricPrompt.
`width`	`int`: The total width of the prompt in pixels.
`height`	`int`: The total height of the prompt in pixels.
`cornerRadius`	`int`: The corner radius of the prompt in pixels.

Public methods

describeContents

Added in version 37.2

public 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. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

equals

Added in version 37.2

public boolean equals (Object o)

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.

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
`o`	`Object`: the reference object with which to compare.

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

getBackgroundColor

Added in version 37.2

public int getBackgroundColor ()

Returns
`int`	The background color for BiometricPrompt.

getCornerRadius

Added in version 37.2

public int getCornerRadius ()

Returns
`int`	The corner radius of the prompt in pixels.

getHeight

Added in version 37.2

public int getHeight ()

Returns
`int`	The total height of the prompt in pixels.

getWidth

Added in version 37.2

public int getWidth ()

Returns
`int`	The total width of the prompt in pixels.

hashCode

Added in version 37.2

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.

writeToParcel

Added in version 37.2

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`dest`	`Parcel`: This value cannot be `null`.
`flags`	`int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of the following: `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`
