HarmonyOS如何监听输入法右上角关闭按键

import { inputMethod } from '@kit.IMEKit'
import { BusinessError } from '@kit.BasicServicesKit'

@Entry
@Component
struct InputTest {
build() {
Column() {
TextInput()

Button('11')
.onClick(() => {
try {
let inputMethodController = inputMethod.getController();
inputMethodController.stopInputSession().then((result) => {
if (result) {
console.info('Succeeded in stopping inputSession.');
} else {
console.error('Failed to stopInputSession.');
}
}).catch((err : BusinessError) => {
console.error('Failed to stopInputSession: ' + JSON.stringify(err));
})
} catch(err) {
console.error('Failed to stopInputSession: ' + JSON.stringify(err));
}
})
}
}
}
