如何在ionic4中获取键盘的高度

import { Platform } from '@ionic/angular';
import { Keyboard } from '@ionic-native/keyboard/ngx';

constructor(private platform: Platform, private keyboard: Keyboard) { }

getKeyboardHeight() {
  if (this.platform.is('cordova')) { // 仅在 Cordova 环境下运行
    this.keyboard.onKeyboardShow().subscribe((e) => {
      console.log('键盘高度：', e.keyboardHeight);
    });
  }
}
