How to translate mobile app text using language drop-down inside react-native app? - react-native

Question

I want to add translate drop-down inside mobile app to translate the app text without using language json file.
I just want to add the select list at the top of app to change the language of text, like this: https://www.w3schools.com/howto/tryit.asp?filename=tryhow_google_translate
Is this possible with react native app?

Answer 1

Here is an example of how you can achieve that.
Working Example: Expo Snack
import React, { useState } from 'react';
import { Text, View, StyleSheet, Picker } from 'react-native';
import Constants from 'expo-constants';
const engToHindi = {
english: 'hello',
hindi: 'नमस्कार',
};
export default function App() {
const [language, setLanguage] = useState('english');
return (
<View style={styles.container}>
<Picker
selectedValue={language}
style={{ height: 50, width: 100 }}
onValueChange={(itemValue) => setLanguage(itemValue)}>
<Picker.Item label="English" value="english" />
<Picker.Item label="हिन्दी" value="hindi" />
</Picker>
<Text>{engToHindi[language]}</Text>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
paddingTop: Constants.statusBarHeight,
backgroundColor: '#ecf0f1',
padding: 8,
},
});
Online Implementation using Google Translate API would be possible but I don't have the API keys so could not give you the example of that implementation.
