TextServicesManager
class TextServicesManager
| kotlin.Any | |
| ↳ | android.view.textservice.TextServicesManager |
System API to the overall text services, which arbitrates interaction between applications and text services. The user can change the current text services in Settings. And also applications can specify the target text services.
Architecture Overview
There are three primary parties involved in the text services framework (TSF) architecture:
- The text services manager as expressed by this class is the central point of the system that manages interaction between all other parts. It is expressed as the client-side API here which exists in each application context and communicates with a global system service that manages the interaction across all processes.
- A text service implements a particular interaction model allowing the client application to retrieve information of text. The system binds to the current text service that is in use, causing it to be created and run.
- Multiple client applications arbitrate with the text service manager for connections to text services.
Text services sessions
- The spell checker session is one of the text services.

bundle |
Bundle?: This value may be null. |

listener: SpellCheckerSession.SpellCheckerSessionListener
): SpellCheckerSession?
Get a spell checker session from the spell checker.
| Parameters | |
|---|---|
params |
SpellCheckerSession.SpellCheckerSessionParams: The parameters passed to the spell checker. This value cannot be null. |
executor |
Executor: The executor on which listener will be called back. This value cannot be null.
