Question

我正在使用本机和世博会开发应用程序，我在Android上遇到了键盘问题。当键盘弹出时，它会将视图向上推得太多，导致标题在中间被剪切。在iOS上它很好。我想达到同样的行为..

我查看了文档，但它说Android会自动处理它。但它没有这样做：/

这是我的代码：

render() {
    const { erroLogin, logando } = this.props;

    return (
      <ImageBackground style={styles.container} source={backgroundImage}>
        <KeyboardAvoidingView 
          style={styles.keyboardViewContainer} 
          behavior={Platform.OS === 'ios' ? 'padding' : null}
        >
          <Text
            style={{
              fontFamily: 'roboto-bold',
              color: '#ffffff',
              fontSize: 48,
              marginBottom: 20.7 * 3,
            }}
          >
          Balad<Text style={{ fontFamily: 'roboto-light', color: '#ffffff', fontSize: 48 }}>APP</Text>
          </Text>

          <TextInput
            value={this.state.email}
            placeholder="Usuário"
            style={[styles.input, { marginBottom: 4 * 3 }]}
            placeholderTextColor="#828282"
            maxLength={255}
            autoCorrect={false}
            keyboardType="email-address"
            autoCapitalize="none"
            returnKeyType="done"
            underlineColorAndroid="transparent"
            onChangeText={text => this.setState({ email: text })}
          />

          <TextInput
            value={this.state.senha}
            placeholder="Senha"
            style={styles.input}
            placeholderTextColor="#828282"

            underlineColorAndroid="transparent"
            onChangeText={text => this.setState({ senha: text })}
          />

          <View style={styles.esqueceuView}>
            <TouchableOpacity onPress={this.esqueciMinhaSenha}>
              <Text style={styles.esqueceuSenha}>Esqueceu a senha?</Text>
            </TouchableOpacity>

            <Text style={styles.continuarConectadoText}>Manter conectado</Text>

Answer 1

我在世博论坛上发布了这个问题，我得到了答案。

我所要做的就是将内容包装在ScrollView中的KeyboardAvoidView中，并且它有效。仍然试图弄清楚为什么这是必要的，因为文档没有说明任何内容。

无论如何，这里是答案https://forums.expo.io/t/problems-with-keyboardavoidview/7799

的链接

我希望它可以帮助其他人。

Answer 2

SDK 37目前还有另一个解决方法。只需将此样式代码添加到屏幕的根视图即可：

{minHeight：Math.round（windowHeight））}

然后键盘将不会调整视图的大小。


import React from 'react';
import {
  StyleSheet, View, useWindowDimensions,
} from 'react-native';


export default function AvoidViewMoving() {
  const windowHeight = useWindowDimensions().height;

  return (
    <View
      style={[{ minHeight: Math.round(windowHeight) }]}
    >
      {/* Your stuff */}
    </View>
  );
}

这个想法不是我的。感谢Ksedline在GitHub上发表以下评论： https://github.com/expo/expo/issues/7589#issuecomment-629863678

尝试将 KeyboardAvoidingView 中的所有内容都包含在 ScrollView

中

 <KeyboardAvoidingView style={{ flex: 1}}
            behavior={Platform.OS === 'ios' ? 'padding' : 'height'}
        >

       <ScrollView>
    //your container view is here
       </ScrollView>

    </KeyboardAvoidingView>
