Gulir ke input pada tombol klik reaksi asli

I cant gurantee this is the best approach.

Add this.scroll.scrollTo({ x: calculatedStartPositionOfTheScreen}) to your button Press handler https://facebook.github.io/react-native/docs/scrollview#scrollto

e.g

<View>
    ...
    <View style={styles.ButtonContainer}>
        <Button title="Screen 1" onPress={() => { this.scroll.scrollTo({ x: 0 }) }} />
    </View>
    <View style={styles.ButtonContainer}>
        <Button title="Screen 2" onPress={() => { this.scroll.scrollTo({ x: screenWidth }) }} />
    </View>
    <View style={styles.ButtonContainer}>
        <Button title="Screen 3" onPress={() => { this.scroll.scrollTo({ x: screenWidth * 2 }) }} />
    </View>
    ...
    <ScrollView
        horizontal={true}
        pagingEnabled={true}
        showsHorizontalScrollIndicator={false}
        ref={(node) => this.scroll = node}
    >
    ...
    </ScrollView>
</View >
