import { inputMethodEngine } from '@kit.IMEKit';
import { BusinessError } from '@kit.BasicServicesKit';
static onKeyboardListener(callback: (show: boolean) => void) {
  try {
    inputMethodEngine.getInputMethodAbility().on('keyboardShow', () => {
      if (callback) {
        callback(true); //键盘显示
      }
    });
    inputMethodEngine.getInputMethodAbility().on('keyboardHide', () => {
      if (callback) {
        callback(false); //键盘隐藏
      }
    });
  } catch (err) {
    let error = err as BusinessError;
    console.log(`KeyboardUtil-onKeyboardListener-异常 ~ code: ${error.code} -·- message: ${error.message}`);
  }
}
