React Native ScrollView Wrapping for Complex Elements


I've got a ScrollView and I'm listing a few Components in it. So far, I'd been putting just one big Text component in the ScrollView and it was wrapping fine. But now that I've created a new Component (in this case, ComplexText), the wrapping is a little off. (The ComplexText components are listed appropriately, it's just that long messages wrap a little funny and the last few characters of each wrapped line fall off of the screen.

Here's a basic form of my code:

import React, { ReactElement } from "react";
import {ScrollView, View, Text} from "react-native";

interface TextProps {
    person: string,
    message: string;
}

const ComplexText = ({person, message} : TextProps) : ReactElement => {
    return (
        <View style={{flexDirection: "row"}}>
            <Text textBreakStrategy={"simple"} style={{fontSize: 20, fontWeight: "bold"}}>{person + ": "}</Text>
            <Text textBreakStrategy={"simple"} style={{fontSize: 20}}>{message}</Text>
        </View>
    );
};

const ScrollingComplexText = () : ReactElement => {
    return (
        <>
            <View style={{flex:0.05}} key={"status-bar-background"}/>
            <ScrollView style={{backgroundColor: "lightblue"}} key={"scrolling-messages"}>
                <ComplexText person={"Samantha"} message={"Hello Anthony."} />
                <ComplexText person={"Anthony"} message={"Hello Samantha."} />
                <ComplexText person={"System"} message={"User Jonathan has joined the chat, say something to welcome him."} />
                <ComplexText person={"Anthony"} message={"Hello Jonathan."} />
                <ComplexText person={"Samantha"} message={"Hello Jonathan."} />
                <ComplexText person={"Jonathan"} message={"Hello everybody."} />
            </ScrollView>
        </>
    );
};

export default ScrollingComplexText;

And here's a screenshot of the issue (as you can tell, most of the word something is being cut off): enter image description here

Edit I also tried doing this with a FlatList, but I'm seeing the exact same thing:

import React, { ReactElement } from "react";
import {View, Text, FlatList} from "react-native";

interface TextProps {
    person: string,
    message: string;
}

const ComplexText = ({person, message} : TextProps) : ReactElement => {
    return (
        <View style={{flexDirection: "row"}}>
            <Text textBreakStrategy={"simple"} style={{fontSize: 20, fontWeight: "bold"}}>{person + ": "}</Text>
            <Text textBreakStrategy={"simple"} style={{fontSize: 20}}>{message}</Text>
        </View>
    );
};

const messageJson = [
    {
        person: "Samantha",
        message: "Hello Anthony."
    },{
        person: "Anthony",
        message: "Hello Samantha."
    },{
        person: "System",
        message: "User Jonathan has joined the chat, say something to welcome him."
    },{
        person: "Anthony",
        message: "Hello Jonathan."
    },{
        person: "Samantha",
        message: "Hello Jonathan."
    },{
        person: "Jonathan",
        message: "Hello Everybody."
    }
];

const ScrollingComplexText = () : ReactElement => {

    const renderItem = ({item} : {item: TextProps}) => (
        <ComplexText person={item.person} message={item.message} />
    );

    return (
        <>
            <View style={{flex:0.05}} key={"status-bar-background"}/>
            <FlatList
                style={{backgroundColor: "lightblue"}}
                data={messageJson}
                renderItem={renderItem} />
        </>
    );
};

export default ScrollingComplexText;

Solution

  • I found my solution to this problem:

    const ComplexText = ({person, message} : TextProps) : ReactElement => {
        return (
            <View style={{flexDirection: "row"}}>
                <Text textBreakStrategy={"simple"} style={{flex: 0.2, fontSize: 20, fontWeight: "bold"}}>{person + ": "}</Text>
                <Text textBreakStrategy={"simple"} style={{flex: 0.8, fontSize: 20}}>{message}</Text>
            </View>
        );
    };
    

    If it's unclear what I added, I needed to add some flex properties to each of the individual Text components within my ComplexText component.
