React Native KeyboardAvoidingView 无法正常工作

Question

我正在尝试使用带有行为=“padding”的KeyboardAvoidingView。

当我尝试在 TextInput 中输入任何文本时，TextInput 字段不会向上移动。我最后添加了一个正在向上移动的小视图，但它上面的视图。

我还使用带有偏移量的 KeyboardAvoidingView height 属性。它只运行几个组件，例如 2 个 TextInputs。但是当我添加所有组件时，用户界面变得疯狂并且行为混乱。

知道这里发生了什么吗？

这是我关注的教程链接。

render() {
    return (
        <View style={styles.backgroundContainer}>
            <Loader
                loading={this.state.isLoading} />
            <KeyboardAvoidingView
                keyboardVerticalOffset={10}
                style={styles.mainContainer}
                behavior='padding' >

我使用了KeyboardAvoidingView，它也不起作用。我找到了这个解决方案，您可以获取基本代码。

安装

npm i react-native-keyboard-aware-scroll-view --save

用法

import { KeyboardAwareScrollView } from 'react-native-keyboard-aware-scroll-view'

<KeyboardAwareScrollView>
  <View>
    <TextInput />
  </View>
</KeyboardAwareScrollView>
