react-native - 键盘在 React Native 博览会上向上推 View

Question

我正在使用 react native 和 Expo 开发一个应用程序，但我在 Android 上遇到了键盘问题。当键盘弹出时，它会将 View 向上推太多，导致标题在中间被切掉。在iOS上没问题。我想实现相同的行为..

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"
            maxLength={255}
            autoCorrect={false}
            autoCapitalize="none"
            returnKeyType="done"
            secureTextEntry
            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>
          </View>

          <CustomCheckBox style={styles.continuarConectadoView} onValueChange={this.switch} value={this.state.continuarConectado}>
            <Text style={styles.continuarConectadoText}>Manter conectado</Text>
          </CustomCheckBox>

          <View style={{ height: 20 * 3, width: '80%' }}>
            <Button
              title="ACESSAR SISTEMA"
              onPress={() => this.fazerLogin()}
              titleStyle={styles.buttonText}
              buttonStyle={styles.button}
              loading={logando}
            />
          </View>
        </KeyboardAvoidingView>

        {erroLogin && (
          <View style={{ width: '80%', height: '10%', borderRadius: 1.7 * 3, marginTop: '5%' }}>
            <ErrorBox
              defaultMessage={
                erroLogin.response.status === 401
                  ? 'Email ou senha incorretos'
                  : 'Ops, houve um erro. Tente novamente'
              }
            />
          </View>
        )}

        <Text style={styles.versao}>{Constants.manifest.version}v</Text>
      </ImageBackground>
    );
  }
}

const styles = StyleSheet.create({

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 KeyboardAvoidView 中的内容包装在 ScrollView 中并且它起作用了。仍在试图弄清楚为什么这是必要的，因为文档没有对此进行任何说明。

无论如何，这是答案的链接https://forums.expo.io/t/problems-with-keyboardavoidview/7799

我希望它可以帮助其他人。
