Summary

Public methods

TextClassifier createTextClassificationSession(TextClassificationContext classificationContext)

Call this method to start a text classification session with the given context.

TextClassifier getTextClassifier()

Returns the text classifier that was set via setTextClassifier(android.view.textclassifier.TextClassifier).

void setTextClassificationSessionFactory(TextClassificationSessionFactory factory)

Sets a TextClassificationSessionFactory to be used to create session-aware TextClassifiers.

void setTextClassifier(TextClassifier textClassifier)

Sets the text classifier.

createTextClassificationSession

Added in API level 28
public TextClassifier createTextClassificationSession (TextClassificationContext classificationContext)

Call this method to start a text classification session with the given context. A session is created with a context helping the classifier better understand what the user needs and consists of queries and feedback events. The queries are directly related to providing useful functionality to the user and the events are a feedback loop back to the classifier helping it learn and better serve future queries.

All interactions with the returned classifier are considered part of a single session and are logically grouped. For example, when a text widget is focused all user interactions around text editing (selection, editing, etc) can be grouped together to allow the classifier get better.

Parameters
classificationContext TextClassificationContext: The context in which classification would occur This value cannot be null.

Returns
TextClassifier An instance to perform classification in the given context This value cannot be null.

getTextClassifier

Added in API level 26
public TextClassifier getTextClassifier ()

Returns the text classifier that was set via setTextClassifier(android.view.textclassifier.TextClassifier). If this is null, this method returns a default text classifier (i.e. either the system text classifier if one exists, or a local text classifier running in this process.)

Note that requests to the TextClassifier may be handled in an OEM-provided process rather than in the calling app's process.

Returns
TextClassifier

setTextClassificationSessionFactory

Added in API level 28
public void setTextClassificationSessionFactory (TextClassificationSessionFactory factory)

Sets a TextClassificationSessionFactory to be used to create session-aware TextClassifiers.

Parameters
factory TextClassificationSessionFactory: the textClassification session factory. If this is null, the default factory will be used.

setTextClassifier

Added in API level 26
public void setTextClassifier (TextClassifier textClassifier)

Sets the text classifier. Set to null to use the system default text classifier. Set to TextClassifier#NO_OP to disable text classifier features.

Parameters
textClassifier TextClassifier: This value may be null.
