在react native中使用KeyboardAvoidingView时，整个内容被推高

Question

I have a issue when using KeyboardAvoidingView in react native. Follow is my code:

<View style={styles.container}>
    <View style = {styles.pagetitle_part}>
        <Text style = {{fontSize: 25, color: '#ffffff'}}> Register User </Text>
        <TouchableOpacity style = {{position: 'absolute', top: 30, left: 20}} onPress = {() => this.props.navigation.navigate('SignIn')}>
            <Image style = {{width: 15, height: 15}} resizeMode = 'contain' source = {require('../assets/images/left_arrow.png')}/>
        </TouchableOpacity>
    </View>
    <View style = {styles.main_part}>
        <ScrollView style = {{width: deviceWidth}} showsVerticalScrollIndicator = {false}>
            <KeyboardAvoidingView behavior = 'padding'>
                <View style = {styles.component_input}>
                    <View style = {styles.title_view}>
                        <Text style = {styles.title_text}> Fist Name </Text>
                    </View>
                    <View style = {styles.input_view}>
                        <TextInput underlineColorAndroid = 'transparent' style = {styles.input_text} onChangeText = {this.handleFirstName}>{this.state.first_name}</TextInput>
                    </View>
                </View>
                <View style = {styles.component_input}>
                    <View style = {styles.title_view}>
                        <Text style = {styles.title_text}> Last Name </Text>
                    </View>
                    <View style = {styles.input_view}>
                        <TextInput underlineColorAndroid = 'transparent' style = {styles.input_text} onChangeText = {this.handleLastName}>{this.state.last_name}</TextInput>
                    </View>
                </View>
                ... ... ...
            </KeyboardAvoidingView>
        </ScrollView>
    </View>
</View>

On Android, when I tap TextInput then upper component is pushed up and so below component is fill out the screen. But on iOS it's Ok.

Follow is screenshot before tapping the TextInput on android:

Follow is screenshot after tapping then TextInput:

As before I said, on iOS, everything is ok. How can I fix this issue on android? Why on iOs is different from on android? I'm very happy to hear your advance. Thanks.

For iOS you should set the "behavior" parameter of the KeyboardAvoidingView to "padding", but not for android. I show a working example in this answer :
