ImageTransformation

class ImageTransformation : Transformation, Parcelable
kotlin.Any
   ↳ android.service.autofill.ImageTransformation

Replaces the content of a child ImageView of a presentation template with the first image that matches a regular expression (regex).

Typically used to display credit card logos. Example:

 new ImageTransformation.Builder(ccNumberId, Pattern.compile("^4815.*$"), R.drawable.ic_credit_card_logo1, "Brand 1") .addOption(Pattern.compile("^1623.*$"), R.drawable.ic_credit_card_logo2, "Brand 2") .addOption(Pattern.compile("^42.*$"), R.drawable.ic_credit_card_logo3, "Brand 3") .build(); 

There is no imposed limit in the number of options, but keep in mind that regexs are expensive to evaluate, so use the minimum number of regexs and add the most common first (for example, if this is a tranformation for a credit card logo and the most common credit card issuers are banks X and Y, add the regexes that resolves these 2 banks first).
Requires API level 27 (Android 8.1, Oreo)

Summary

Nested classes

Builder for ImageTransformation objects.

Inherited constants
Public methods
Unit
writeToParcel(parcel: Parcel!, flags: Int)

Flatten this object in to a Parcel.

String

Returns a string representation of the object.

Int

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.

Public methods

writeToParcel

added in API level 27
fun writeToParcel(parcel: Parcel!, flags: Int): Unit

Flatten this object in to a Parcel. Requires API level 27 (Android 8.1, Oreo)

Parameters
dest Parcel!: The Parcel in which the object should be written.
flags Parcel!: 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

toString

added in API level 27
fun toString(): String

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode()) 
Requires API level 27 (Android 8.1, Oreo)
Return
String: a string representation of the object.

describeContents

added in API level 27
fun describeContents(): Int

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. Requires API level 27 (Android 8.1, Oreo)

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

Properties

CREATOR

added in API level 27
static val CREATOR: Parcelable.Creator<ImageTransformation!>!

Requires API level 27 (Android 8.1, Oreo)
