CustomDescription

public final class CustomDescription
extends Object implements Parcelable

java.lang.Object
↳	android.service.autofill.CustomDescription

Defines a custom description for the autofill save UI.

This is useful when the autofill service needs to show a detailed view of what would be saved; for example, when the screen contains a credit card, it could display a logo of the credit card bank, the last four digits of the credit card number, and its expiration number.

A custom description is made of 2 parts:

A RemoteViews containing children views.
Transformation to populate the children views.

For the credit card example mentioned above, the (simplified) template would be:

 <LinearLayout>
   <ImageView android:id="@+id/templateccLogo"/>
   <TextView android:id="@+id/templateCcNumber"/>
   <TextView android:id="@+id/templateExpDate"/>
 </LinearLayout>

Which in code translates to:

   CustomDescription.Builder buider = new Builder(new RemoteViews(pgkName, R.layout.cc_template);

Then the value of each of the 3 children would be changed at runtime based on the the value of the screen fields and the Transformation:

 // Image child - different logo for each bank, based on credit card prefix
 builder.addChild(R.id.templateccLogo,
   new ImageTransformation.Builder(ccNumberId)
     .addOption(Pattern.compile("^4815.*$"), R.drawable.ic_credit_card_logo1)
     .addOption(Pattern.compile("^1623.*$"), R.drawable.ic_credit_card_logo2)
     .addOption(Pattern.compile("^42.*$"), R.drawable.ic_credit_card_logo3)
     .build();
 // Masked credit card number (as .....LAST_4_DIGITS)
 builder.addChild(R.id.templateCcNumber, new CharSequenceTransformation
     .Builder(ccNumberId, Pattern.compile("^.*(\\d\\d\\d\\d)$"), "...$1")
     .build();
 // Expiration date as MM / YYYY:
 builder.addChild(R.id.templateExpDate, new CharSequenceTransformation
     .Builder(ccExpMonthId, Pattern.compile("^(\\d\\d)$"), "Exp: $1")
     .addField(ccExpYearId, Pattern.compile("^(\\d\\d)$"), "/$1")
     .build();

See ImageTransformation, CharSequenceTransformation for more info about these transformations.

Summary

Nested classes
`class`	`CustomDescription.Builder` Builder for `CustomDescription` objects.

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.
`int`	`PARCELABLE_WRITE_RETURN_VALUE` Flag for use with `writeToParcel(Parcel, int)`: the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`".

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

Public methods
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`String`	`toString()` Returns a string representation of 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 timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

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

public static final Creator<CustomDescription> CREATOR

Public methods

describeContents

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(android.os.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`

toString

public String toString ()

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())

Returns
`String`	a string representation of the object.

writeToParcel

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`dest`	`Parcel`: The Parcel in which the object should be written.
`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 `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
