29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public T setActionIndices (int... actionIndices) ``` Sets the indices of the actions involved in this event. Actions are usually returned by the text classifier in priority order with the most preferred action at index 0. These indices give an indication of the position of the actions that are being reported. E.g. ``` // 3 smart actions are shown at index 0, 1, 2 respectively in response to a link click. new TextClassifierEvent.Builder(CATEGORY_LINKIFY, TYPE_ACTIONS_SHOWN) .setEventIndex(0, 1, 2) ... .build(); ... // Smart action at index 1 is activated. new TextClassifierEvent.Builder(CATEGORY_LINKIFY, TYPE_SMART_ACTION) .setEventIndex(1) ... .build(); ```

| Parameters || |-----------------|-------------------------------------------| | `actionIndices` | `int`: This value cannot be`null`.
| | Returns || |-----|------------------------------------| | `T` | This value cannot be`null`.

Supported types: See[TextClassifier](https://developer.android.com/reference/android/view/textclassifier/TextClassifier)types See[ConversationAction](https://developer.android.com/reference/android/view/textclassifier/ConversationAction)types See[ULocale.toLanguageTag()](https://developer.android.com/reference/android/icu/util/ULocale#toLanguageTag())
| Parameters || |---------------|----------------------------------------------| | `entityTypes` | `String`: This value cannot be`null`.
| | Returns || |-----|------------------------------------| | `T` | This value cannot be`null`.
| ### setEventContext Added in[API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public T setEventContext (TextClassificationContext eventContext) ``` Sets the event context.
| Parameters || |----------------|--------------------------------------------------------------| | `eventContext` | `TextClassificationContext`: This value may be`null`.
| | Returns || |-----|------------------------------------| | `T` | This value cannot be`null`.
| ### setEventIndex Added in[API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public T setEventIndex (int eventIndex) ``` Sets the index of this event in the series of events it belongs to.
| Parameters || |--------------|--------------| | `eventIndex` | `int`
| | Returns || |-----|------------------------------------| | `T` | This value cannot be`null`.
| ### setExtras Added in[API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public T setExtras (Bundle extras) ``` Sets a bundle containing non-structured extra information about the event. **NOTE:**Prefer to set only immutable values on the bundle otherwise, avoid updating the internals of this bundle as it may have unexpected consequences on the clients of the built event object. For similar reasons, avoid depending on mutable objects in this bundle.
| Parameters || |----------|----------------------------------------------| | `extras` | `Bundle`: This value cannot be`null`.
| | Returns || |-----|------------------------------------| | `T` | This value cannot be`null`.
| ### setLocale Added in[API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public T setLocale (ULocale locale) ``` Sets the detected locale.
| Parameters || |----------|--------------------------------------------| | `locale` | `ULocale`: This value may be`null`.
| | Returns || |-----|------------------------------------| | `T` | This value cannot be`null`.
| ### setModelName Added in[API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public T setModelName (String modelVersion) ``` Sets the model name string.
| Parameters || |----------------|-------------------------------------------| | `modelVersion` | `String`: This value may be`null`.
| | Returns || |-----|------------------------------------| | `T` | This value cannot be`null`.
| ### setResultId Added in[API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public T setResultId (String resultId) ``` Sets the id of the text classifier result related to this event.
| Parameters || |------------|-------------------------------------------| | `resultId` | `String`: This value may be`null`.
| | Returns || |-----|------------------------------------| | `T` | This value cannot be`null`.
| ### setScores Added in[API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public T setScores (float... scores) ``` Sets the scores of the suggestions.
| Parameters || |----------|---------------------------------------------| | `scores` | `float`: This value cannot be`null`.
| | Returns || |-----|------------------------------------| | `T` | This value cannot be`null`.
