⌨️ Keyboard Handling in React Native

? Quick Overview

Keyboard handling in React Native is essential when building forms or input-heavy screens. Without proper handling, the on-screen keyboard may cover input fields, buttons, or important UI elements. React Native provides built-in components to manage keyboard behavior smoothly across Android and iOS.

? Key Concepts

• KeyboardAvoidingView – Automatically moves UI when keyboard appears
• ScrollView – Enables scrolling when content is hidden by keyboard
• Keyboard API – Listens to keyboard show/hide events
• Platform – Handles platform-specific behavior

? Syntax / Theory

The most common approach is wrapping your screen or form inside a KeyboardAvoidingView. This component adjusts its layout based on the keyboard visibility. On iOS, padding behavior is commonly used, while Android often works well with height adjustment.

? Code Example(s)

// Basic keyboard handling using KeyboardAvoidingView
import React from "react";
import { View, TextInput, Button, KeyboardAvoidingView, Platform } from "react-native";

export default function App() {
  return (
    <KeyboardAvoidingView
      behavior={Platform.OS === "ios" ? "padding" : "height"}
      style={{ flex: 1, justifyContent: "center", padding: 20 }}
    >
      <TextInput
        placeholder="Enter username"
        style={{ borderWidth: 1, marginBottom: 12, padding: 10 }}
      />
      <TextInput
        placeholder="Enter password"
        secureTextEntry
        style={{ borderWidth: 1, marginBottom: 12, padding: 10 }}
      />
      <Button title="Login" onPress={() => {}} />
    </KeyboardAvoidingView>
  );
}
