怎么监听键盘的弹起和关闭事件？

import inputMethodEngine from '@ohos.inputMethodEngine';



let InputMethodEngine = inputMethodEngine.getInputMethodEngine();


InputMethodEngine.on('keyboardShow', () => {

console.log('inputMethodEngine keyboardShow.');

});


InputMethodEngine.on('keyboardHide', () => {

     console.log('inputMethodEngine keyboardHide.');

});
