Mobile apps are not just static screens. Users need to interact with them.

In React Native, two basic components handle this:

• TextInput: allows users to enter text;
• Button: allows users to trigger actions.

Example:

import { View, Text, TextInput, Button, StyleSheet } from 'react-native';

export default function App() {
  return (
    <View style={styles.container}>
      <Text style={styles.title}>Contact</Text>

      <TextInput
        placeholder="Enter your name"
        style={styles.input}
      />

      <Button title="Submit" onPress={() => console.log('Button pressed')} />
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    padding: 20
  },
  title: {
    fontSize: 20,
    marginBottom: 10
  },
  input: {
    borderWidth: 1,
    padding: 10,
    marginBottom: 10
  }
});

TextInput lets the user type something. Button reacts to a press using the onPress property.

Now your screen is not just visual — it can respond to user actions.
