Rich ReactNative TextInput

Question

Any way to create a "rich" TextInput in React Native? Maybe not a full blown wysiwyg, but maybe just change the text color of various pieces of text; like the @mention feature on Twitter or Facebook.

Answer 1

This question was asked a while ago but I think my answer can help other people looking for how to color the @mention part of a string. I am not sure if the way I did it is clean or the "react" way but here is how I did it: I take the inputed string and split it with an empty space as the separator. I then loop through the array and if the current item matches the pattern of @mention/@user, it is replaced with the Text tag with the styles applied; else return the item. At the end, I render inputText array (contains strings and jsx elements)inside the TextInput element. Hope this helps!

render() {
let inputText = this.state.content;
if (inputText){
  inputText = inputText.split(/(\s)/g).map((item, i) => {
    if (/@[a-zA-Z0-9]+/g.test(item)){
      return <Text key={i} style={{color: 'green'}}>{item}</Text>;
    } 
    return item;
  })
return <TextInput>{inputText}</TextInput>

Solution is that you can use <Text> elements as children in a <TextInput> like this:

<TextInput>
    whoa no way <Text style={{color:'red'}}>rawr</Text>
</TextInput>
