class
AccessibilityService.SoftKeyboardController
extends Object
| java.lang.Object | |
| ↳ | android.accessibilityservice.AccessibilityService.SoftKeyboardController |
Used to control, query, and listen for changes to the soft keyboard show mode.
Accessibility services may request to override the decisions normally made about whether or not the soft keyboard is shown.
If multiple services make conflicting requests, the last request is honored. A service may register a listener to find out if the mode has changed under it.
If the user takes action to override the behavior behavior requested by an accessibility
service, the user's request takes precendence, the show mode will be reset to
AccessibilityService#SHOW_MODE_AUTO, and services will no longer be able to control
that aspect of the soft keyboard's behavior.
Note: Because soft keyboards are independent apps, the framework does not have total control over their behavior. They may choose to show themselves, or not, without regard to requests made here. So the framework will make a best effort to deliver the behavior requested, but cannot guarantee success.
