Public constructors

public Builder (RemoteViews presentation)

Creates a new builder.

Parameters
`presentation`	`RemoteViews`: The presentation used to visualize this dataset. This value cannot be `null`.

Builder

public Builder ()

Creates a new builder for a dataset where each field will be visualized independently.

When using this constructor, fields must be set through setValue(android.view.autofill.AutofillId, android.view.autofill.AutofillValue, android.widget.RemoteViews) or setValue(android.view.autofill.AutofillId, android.view.autofill.AutofillValue, java.util.regex.Pattern, android.widget.RemoteViews).

Public methods

build

public Dataset build ()

Creates a new Dataset instance.

You should not interact with this builder once this method is called.

Returns
`Dataset`	The built dataset. This value cannot be `null`.

Throws

IllegalStateException if no field was set (through setValue(android.view.autofill.AutofillId, android.view.autofill.AutofillValue) or setValue(android.view.autofill.AutofillId, android.view.autofill.AutofillValue, android.widget.RemoteViews) or setValue(android.view.autofill.AutofillId, android.view.autofill.AutofillValue, android.widget.RemoteViews, android.service.autofill.InlinePresentation)), or if build() was already called.

Throws
`IllegalStateException`	if no field was set (through `setValue(android.view.autofill.AutofillId, android.view.autofill.AutofillValue)` or `setValue(android.view.autofill.AutofillId, android.view.autofill.AutofillValue, android.widget.RemoteViews)` or `setValue(android.view.autofill.AutofillId, android.view.autofill.AutofillValue, android.widget.RemoteViews, android.service.autofill.InlinePresentation)`), or if `build()` was already called.

setAuthentication

public Dataset.Builder setAuthentication (IntentSender authentication)

Triggers a custom UI before before autofilling the screen with the contents of this dataset.

Note: Although the name of this method suggests that it should be used just for authentication flow, it can be used for other advanced flows; see AutofillService for examples.

This method is called when you need to provide an authentication UI for the data set. For example, when a data set contains credit card information (such as number, expiration date, and verification code), you can display UI asking for the verification code before filing in the data. Even if the data set is completely populated the system will launch the specified authentication intent and will need your approval to fill it in. Since the data set is "locked" until the user authenticates it, typically this data set name is masked (for example, "VISA....1234"). Typically you would want to store the data set labels non-encrypted and the actual sensitive data encrypted and not in memory. This allows showing the labels in the UI while involving the user if one of the items with these labels is chosen. Note that if you use sensitive data as a label, for example an email address, then it should also be encrypted.

When a user triggers autofill, the system launches the provided intent whose extras will have the screen content, and your client state. Once you complete your authentication flow you should set the activity result to Activity.RESULT_OK and provide the fully populated Dataset or a fully-populated FillResponse by setting it to the AutofillManager.EXTRA_AUTHENTICATION_RESULT extra. If you provide a dataset in the result, it will replace the authenticated dataset and will be immediately filled in. An exception to this behavior is if the original dataset represents a pinned inline suggestion (i.e. any of the field in the dataset has a pinned inline presentation, see InlinePresentation#isPinned()), then the original dataset will not be replaced, so that it can be triggered as a pending intent again. If you provide a response, it will replace the current response and the UI will be refreshed. For example, if you provided credit card information without the CVV for the data set in the FillResponse then the returned data set should contain the CVV entry.

Note: Do not make the provided pending intent immutable by using PendingIntent.FLAG_IMMUTABLE as the platform needs to fill in the authentication arguments.

Parameters
`authentication`	`IntentSender`: Intent to an activity with your authentication flow. This value may be `null`.

Returns
`Dataset.Builder`	this builder. This value cannot be `null`.

Throws
`IllegalStateException`	if `build()` was already called.

PendingIntent

setId

public Dataset.Builder setId (String id)

Sets the id for the dataset so its usage can be tracked.

Dataset usage can be tracked for 2 purposes:

For statistical purposes, the service can call AutofillService#getFillEventHistory() when handling AutofillService#onFillRequest(FillRequest, android.os.CancellationSignal, FillCallback) calls.
For normal autofill workflow, the service can call SaveRequest#getDatasetIds() when handling AutofillService#onSaveRequest(SaveRequest, SaveCallback) calls.

Parameters
`id`	`String`: id for this dataset or `null` to unset. This value may be `null`.

Returns
`Dataset.Builder`	this builder.

Throws
`IllegalStateException`	if `build()` was already called.

setInlinePresentation

public Dataset.Builder setInlinePresentation (InlinePresentation inlinePresentation)

Sets the InlinePresentation used to visualize this dataset as inline suggestions. If the dataset supports inline suggestions this should not be null.

Parameters
`inlinePresentation`	`InlinePresentation`: This value cannot be `null`.

Returns
`Dataset.Builder`	this builder.

Throws
`IllegalStateException`	if `build()` was already called.

setValue

public Dataset.Builder setValue (AutofillId id, 
                AutofillValue value, 
                Pattern filter)

Sets the value of a field using an explicit filter.

This method is typically used when the dataset requires authentication and the service does not know its value but wants to hide the dataset after the user enters a minimum number of characters. For example, if the dataset represents a credit card number and the service does not want to show the "Tap to authenticate" message until the user tapped 4 digits, in which case the filter would be Pattern.compile("\\d.{4,}").

Note: If the dataset requires authentication but the service knows its text value it's easier to filter by calling setValue(android.view.autofill.AutofillId, android.view.autofill.AutofillValue) and use the value to filter.

Parameters
`id`	`AutofillId`: id returned by `AssistStructure.ViewNode.getAutofillId()`. This value cannot be `null`.
`value`	`AutofillValue`: the value to be autofilled. Pass `null` if you do not have the value but the target view is a logical part of the dataset. For example, if the dataset needs authentication and you have no access to the value. This value may be `null`.
`filter`	`Pattern`: regex used to determine if the dataset should be shown in the autofill UI; when `null`, it disables filtering on that dataset (this is the recommended approach when `value` is not `null` and field contains sensitive data such as passwords). This value may be `null`.

Returns
`Dataset.Builder`	this builder.

Throws
`IllegalStateException`	if the builder was constructed without a `RemoteViews` or `build()` was already called.

                AutofillValue value,

Parameters
`id`	`AutofillId`: id returned by `AssistStructure.ViewNode.getAutofillId()`. This value cannot be `null`.
`value`	`AutofillValue`: the value to be autofilled. Pass `null` if you do not have the value but the target view is a logical part of the dataset. For example, if the dataset needs authentication and you have no access to the value. This value may be `null`.

Sets the value of a field, using a custom RemoteViews to visualize it and an InlinePresentation to visualize it as an inline suggestion.

Parameters
`id`	`AutofillId`: id returned by `AssistStructure.ViewNode.getAutofillId()`. This value cannot be `null`.
`value`	`AutofillValue`: the value to be autofilled. Pass `null` if you do not have the value but the target view is a logical part of the dataset. For example, if the dataset needs authentication and you have no access to the value. This value may be `null`.

public Dataset.Builder setValue (AutofillId id, 
                AutofillValue value, 
                RemoteViews presentation)

Sets the value of a field, using a custom RemoteViews to visualize it.

Note: On Android Build.VERSION_CODES.P and higher, datasets that require authentication can be also be filtered by passing a AutofillValue#forText(CharSequence) as the value parameter.

Theme does not work with RemoteViews layout. Avoid hardcoded text color or background color: Autofill on different platforms may have different themes.

Parameters
`id`	`AutofillId`: id returned by `AssistStructure.ViewNode.getAutofillId()`. This value cannot be `null`.
`value`	`AutofillValue`: the value to be autofilled. Pass `null` if you do not have the value but the target view is a logical part of the dataset. For example, if the dataset needs authentication and you have no access to the value. This value may be `null`.
`presentation`	`RemoteViews`: the presentation used to visualize this field. This value cannot be `null`.

Returns
`Dataset.Builder`	this builder.

Throws
`IllegalStateException`	if `build()` was already called.

setValue

public Dataset.Builder setValue (AutofillId id, 
                AutofillValue value)

Sets the value of a field. Note: Prior to Android Build.VERSION_CODES.P, this method would throw an IllegalStateException if this builder was constructed without a RemoteViews. Android Build.VERSION_CODES.P and higher removed this restriction because datasets used as an authentication result do not need a presentation. But if you don't set the presentation in the constructor in a dataset that is meant to be shown to the user, the autofill UI for this field will not be displayed.

Note: On Android Build.VERSION_CODES.P and higher, datasets that require authentication can be also be filtered by passing a AutofillValue#forText(CharSequence) as the value parameter.

Parameters
`id`	`AutofillId`: id returned by `AssistStructure.ViewNode.getAutofillId()`. This value cannot be `null`.
`value`	`AutofillValue`: value to be autofilled. Pass `null` if you do not have the value but the target view is a logical part of the dataset. For example, if the dataset needs authentication and you have no access to the value. This value may be `null`.

Returns
`Dataset.Builder`	this builder.

Throws
`IllegalStateException`	if `build()` was already called.

public Dataset.Builder setValue (AutofillId id, 
                AutofillValue value, 
                Pattern filter, 
                RemoteViews presentation)

Sets the value of a field, using a custom RemoteViews to visualize it and a explicit filter.

Parameters
`id`	`AutofillId`: id returned by `AssistStructure.ViewNode.getAutofillId()`. This value cannot be `null`.
`value`	`AutofillValue`: the value to be autofilled. Pass `null` if you do not have the value but the target view is a logical part of the dataset. For example, if the dataset needs authentication and you have no access to the value. This value may be `null`.
`filter`	`Pattern`: regex used to determine if the dataset should be shown in the autofill UI; when `null`, it disables filtering on that dataset (this is the recommended approach when `value` is not `null` and field contains sensitive data such as passwords). This value may be `null`.
`presentation`	`RemoteViews`: the presentation used to visualize this field. This value cannot be `null`.

Returns
`Dataset.Builder`	this builder.

Throws
`IllegalStateException`	if `build()` was already called.
