Как исправить белое пространство клавиатуры, которое отображается, когда я использую KeyboardAwareView или реакцию-родной-осведомленный-клавиатура-прокрутка-просмотр в моей реакции-родной Экспо?

Question

Я использую Expo - response-native при создании приложения, но при использовании KeyboardAvoidingView и других пакетов клавиатуры (Reaction-native-клавиатура-aware-scroll-view) в нижней части экрана отображаются пробелы. Как это исправить? (https://i.stack.imgur.com/1c0M6.jpg) пытался использовать KeyboardAvoidingView и реагировать на встроенную клавиатуру-представление-прокрутка, но проблема все еще сохраняется

Я проверил и изменил ваш код в реагировать родной IOS.Следующий код может быть полезен для вас.

    import React, {Component} from 'react';
    import {StyleSheet,
    ScrollView,
    Dimensions,
    Text,ActivityIndicator,
    TouchableOpacity,
    TextInput,
    View,
    StatusBar,
    ImageBackground,
    KeyboardAvoidingView} from 'react-native';
    let {height, width} = Dimensions.get('window');


    export default class LoginForm extends Component {
    render() {
     return (
     <KeyboardAvoidingView behavior={"padding"} enabled  style= . 
     {{flexGrow:1,height:'100%'}}>
        <ScrollView bounces={false} >
            <StatusBar
            backgroundColor="transparent"
            barStyle="default"
            translucent={true}
            />
            <ImageBackground style={{width: "100%",height: height}} source={require('./bg.jpg')}>
            <View style={{flex:1}}>
                    <View style={styles.title}>
                        <Text style={styles.big}>AgroSight</Text>
                        <Text style={styles.small}>An agro based app for farmers and persons</Text>
                        {
          this.state.ActivityLoader ? <ActivityIndicator color='#FFF' size='large' style={styles.Activity} />: null
        }
                    </View>

            <View style={{flex:2}}>
                    <TextInput
                    style={styles.input}
                    placeholder="Email Address"
                    returnKeyType="next"
                    keyboardType="email-address"
                    autoCapitalize="none"
                    autoCorrect={false}
                    onSubmitEditing = {() => this.passwordInput.focus()}
                    placeholderTextColor="rgba(255,255,255,.7)"
                    name="email"
                    onChangeText={(TextInput) => this.setState({userEmail: TextInput})}

                    />
                    <TextInput
                    style={styles.input}
                    placeholder="Password"
                    returnKeyType="go"
                    secureTextEntry
                    ref={(input) => this.passwordInput = input}
                    placeholderTextColor="rgba(255,255,255,.7)"
                    name="password"
                    onChangeText={(TextInput) => this.setState({password: TextInput})}
                    />

                    <TouchableOpacity style={styles.buttonContainer} onPress={ this.LoginUser }>
                        <Text style={styles.buttonText}>LOG IN</Text>
                    </TouchableOpacity>
            </View>

                    <View style={styles.bottomRow}>
                    <Text style={styles.signupText}> Don't have account ?
                    <Text style={styles.reg} onPress={() => this.props.navigation.navigate('RegisterScreen')}>REGISTER HERE</Text>
                    </Text>
                    </View>
                </View>
            </ImageBackground>
   </ScrollView>
</KeyboardAvoidingView>
);
}
}

const styles = StyleSheet.create({
container: {
flex: 1,
},
title: {
marginTop: 20,
alignItems: "center",
justifyContent:"center",
// height:'30%'
flex:1
},
big: {
marginTop: 20,
fontSize: 50,
color: "white",
alignItems:"center",
fontWeight:"bold",
},
small: {
marginTop: 4,
fontSize: 20,
color:"#FFF",
fontWeight:"bold",
opacity: .8
},
bottomRow: {
padding: 20,
justifyContent: "center",
paddingVertical: 20
},
signupText: {
fontSize: 21,
color:"#FFF",
fontWeight: "700",
alignItems: "center"
},
reg: {
color: "#FED81E",
alignItems: "center"
},
formContainer:{
padding: 20,
flex:1
},
input: {
height: 50,
backgroundColor: "green",
color: "#FFF",
paddingHorizontal: 10,
marginBottom: 10,
borderRadius: 7,
fontSize: 20,
paddingVertical: 10
},
buttonContainer: {
backgroundColor: "#FFF",
paddingVertical: 15,
borderRadius: 8
},
buttonText: {
textAlign: 'center',
color:"green",
fontWeight: '700',
fontSize: 27
},
Activity:{
position: 'absolute',
left: 0,
right: 0,
top: 150,
bottom: 0,
alignItems: 'center',
justifyContent: 'center',
zIndex: 999
},
});

Если вы запустите приведенный выше код в Android, то измените поведение = {"height"}
