The onFocus and onBlur events are not functioning properly in the React Native application

Trying my hand at developing an androidTV application using react-native and following the provided documents. However, despite my efforts, it seems like onFocus and onBlur functions are not working correctly for me. Here is the code snippet I am working with:

const App = () => {
  return (
    <View>
      <TouchableHighlight
        hasTVPreferredFocus={true}
        accessible={true}
        onFocus={() => alert('focus')}
        onBlur={() => alert('blur')}
        onPress={() => alert('press')}>
        <Text>This is a text</Text>
      </TouchableHighlight>
      <Button title="title" />
    </View>
  );
};

In addition to this, I have also included hasTVPreferredFocus and accessible properties to ensure I didn't overlook anything.

Answer №1

After some troubleshooting, I discovered a solution to the issue. It appears that executing

npx react-native init <ProjectName>
did not generate all necessary files. Instead, by running
react-native init <ProjectName> --template=react-native-tvos
, I was able to resolve the problem. This led me to believe that the tvOS version is more suitable for TV development.

Answer №2

Unfortunately, the functionality is not functioning as expected due to the fact that the component is not set up to listen for those specific events. For further clarification, please refer to the relevant documentation at:

https://reactnative.dev/docs/touchablehighlight

Answer №3

import React from 'react';
import { TextInput } from 'react-native';
import { customStyles } from './customStyles';

const CustomInput = (props) => {
  const [isFocused, setIsFocused] = React.useState(false);
  
  return (
    <TextInput
      {...props}
      onFocus={() => setIsFocused(true)}
      onBlur={() => setIsFocused(false)}
      style={isFocused ? customStyles.inputFocused : customStyles.input}
    />
  );
};

export default CustomInput;

If you need to override the onFocus function in your props, position it like this at the beginning
