Click event on words react native

I want to set different click listeners on different words of . Currently what i have is 

<Text>Android iOS React Native<Text>

Now i want to know when user click on Android, iOS and React Native, i have to perform some analytics on that so need click listeners for seperate words.

Does any one have idea about it? I have checked this thread but i din't found it useful for my requirement.

Update String i have given is just an example string, in real time i will be getting dynamic strings.

This is what i will be getting as dynamic string

{
    "str":"Hi i am using React-Native, Earlier i was using Android and so on"
    "tagWords":["React-Native","Android"]
}

And in output i want, "Hi i am using React-Native, Earlier i was using Android and so on"

with click event on "React-Native" and "Android". Is is possible?

The post you sent is the simplest way you can achieve the desired behavior. Sinse you need to have different listeners you need to implement different Text components.

Example

export default class App extends Component {
  onTextPress(event, text) {
    console.log(text);
  }
  render() {
    return (
      <View style={styles.container}>
        <Text>
          <Text onPress={(e) => this.onTextPress(e, 'Android')} style={styles.red}>{'Android '}</Text>
          <Text onPress={(e) => this.onTextPress(e, 'iOS')} style={styles.purple}>{'iOS '}</Text>
          <Text onPress={(e) => this.onTextPress(e, 'React Native')} style={styles.green}>{'React Native'}</Text>
        </Text>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center'
  },
  red: {
    fontSize: 20,
    color: 'red'
  },
  purple: {
    fontSize: 20,
    color: 'purple'
  },
  green: {
    fontSize: 20,
    color: 'green'
  }
});

Update 1 (Dynamic text)

  render() {
    const fixedString = 'I\'m a fixed string that slipleted';
    const arrayOfStrings = ['These', 'are', 'strings', 'from', 'array'];
    return (
      <View style={styles.container}>
        <Text style={styles.textContainer}>
        {
          fixedString.split(' ').map((str, index) => {
            return (
              <Text onPress={(e) => this.onTextPress(e, str)}>
                {`${str}${index !== (fixedString.split(' ').lenght -1) && ' '}`}
              </Text>
            )
          })
        }
        </Text>
        <Text style={styles.textContainer}>
        {
          arrayOfStrings.map((str, index) => {
            return (
              <Text onPress={(e) => this.onTextPress(e, str)}>
                {`${str}${index !== (arrayOfStrings.lenght -1) && ' '}`}
              </Text>
            )
          })
        }
        </Text>
      </View>
    );
  }

Update 2 (for example dynamic data)

  removePunctuation = (text) => {
    // this is a hack to remove comma from the text
    // you may want to handle this different
    return text.replace(/[.,\/#!$%\^&\*;:{}=\_`~()]/g,"");
  }
  render() {
    const arrayOfObjects = [{
      str: 'Hi i am using React-Native, Earlier i was using Android and so on',
      tagWords: ['React-Native', 'Android']
    }];
    return (
      <View style={styles.container}>
        <Text style={styles.textContainer}>
          {
            arrayOfObjects.map((obj) => {
              return obj.str.split(' ').map((s, index) => {
                if ( obj.tagWords.indexOf(this.removePunctuation(s)) > -1 ) {
                  return (
                    <Text onPress={(e) => this.onTextPress(e, s)} style={styles.red}>
                      {`${s} ${index !== (obj.str.split(' ').lenght - 1) && ' '}`}
                    </Text>
                  )
                } else return `${s} `;
              })
            })
          }
        </Text>
      </View>
    );
  }

You can wrap each clickable words into 'TouchableOpacity' component, and tract the onPress event as follows

<View style={{flexDirection: 'row'}}>
   <TouchableOpacity onPress={() => {
        console.log('Android Clicked');
      }}>
      <Text>Android</Text>
   </TouchableOpacity>
   <TouchableOpacity onPress={() => {
       console.log('iOS Clicked');
     }}>
     <Text>Ios</Text>
   </TouchableOpacity>
</View>

Please do adjust the spacing between words.

Edit: For dynamic string you can proceed as follows

...

handleWordClick(str, handler) {
 var words = str.split(' '), // word separator goes here,
     comp = [];
 words.forEach((s, ind) =>{
     comp.push(
       <TouchableOpacity key={ind} onPress={() => handler.call(this, s)}>
          <Text>{s}</Text>
       </TouchableOpacity>
       );
 })
 return comp;
}

render() {
  var comp = this.handleWordClick('Android iOS React-Native', (word) => {
      //handle analytics here...
      console.log(word);
      });
  return (
    <View>
     ...
     <View style={{flexDirection: 'row'}}>
       {comp}
     </View>
     ...
     </View>
    )
}

I am not sure what will be your word separator as the example you have given has 'React Native' as single word. Please pay attention on this part.

Hope this will help you.

all you need to use is TouchableOpacity(for the tap effect and clicks), View for the alignment of texts. and certain styling. I am providing you the code snippet that will work for you , all other syntax will remain same

import {Text, View, TouchableOpacity} from 'react-native'
<View style={{flexDirection:'row'}}>
  <TouchableOpacity onPress={{()=>doSomethingAndroid()}}>
        <Text>Android</Text>
  </TouchableOpacity>
  <TouchableOpacity onPress={{()=>doSomethingiOS()}}><Text> iOS</Text> 
  </TouchableOpacity>
  <TouchableOpacityonPress={{()=>doSomethingReactNative()}}><Text> React Native</Text>
  </TouchableOpacity>
</View>

i hope this works, comment back if any issue happens
