@ohos.InputMethodExtensionContext (InputMethodExtensionContext)
The InputMethodExtensionContext module, inherited from ExtensionContext, provides context for InputMethodExtension abilities.
You can use the APIs of this module to start, terminate, connect, and disconnect abilities.
NOTE
The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
Modules to Import
import InputMethodExtensionContext from '@ohos.InputMethodExtensionContext';
Usage
Before using the InputMethodExtensionContext module, you must define a child class that inherits from InputMethodExtensionAbility.
import InputMethodExtensionAbility from '@ohos.InputMethodExtensionAbility';
class EntryAbility extends InputMethodExtensionAbility {
onCreate() {
let context = this.context;
}
}
InputMethodExtensionContext.destroy
destroy(callback: AsyncCallback<void>): void

console.log('destroy result:' + JSON.stringify(err));

InputMethodExtensionContext.destroy
destroy(): Promise<void>;
