android - KeyboardDidShow/Hide 事件在具有 adjustResize 设置的 Android 上不起作用

Question

我正在尝试使用 React Native 在 Android 上捕获键盘显示/隐藏事件。我陷入了死胡同。

这是我的 list 设置:

<activity
    android:launchMode="singleTop"
    android:name=".MainActivity"
    android:screenOrientation="portrait"
    android:label="@string/app_name"
    android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
    android:windowSoftInputMode="adjustResize">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
        <action android:name="android.intent.action.DOWNLOAD_COMPLETE"/>
    </intent-filter>
</activity>

这是我的 RN 组件:

import React, {Component} from 'react';
import {
    View,Keyboard
} from 'react-native';

export default class KeyboardAwareComponent extends Component {
    componentDidMount() {
        Keyboard.addListener("keyboardDidShow",()=>{
            console.log("Show event");
        })
    }

    render() {
        return <View />
    }
}

非常感谢您提前:)

以下是直接来自文档的一些事件。

keyboardWillShow

键盘显示

键盘会隐藏

键盘隐藏

keyboardWillChangeFrame

keyboardDidChangeFrame

import React, { Component } from 'react';
import { Keyboard, TextInput } from 'react-native';

class Example extends Component {
  componentWillMount () {
    this.keyboardDidShowListener = Keyboard.addListener('keyboardDidShow', this._keyboardDidShow);
    this.keyboardDidHideListener = Keyboard.addListener('keyboardDidHide', this._keyboardDidHide);
  }

  componentWillUnmount () {
    this.keyboardDidShowListener.remove();
    this.keyboardDidHideListener.remove();
  }

  _keyboardDidShow () {
    alert('Keyboard Shown');
  }

  _keyboardDidHide () {
    alert('Keyboard Hidden');
  }

  render() {
    return (
      <TextInput
        onSubmitEditing={Keyboard.dismiss}
      />
    );
  }
}
