🎨 React Native Display Components: Your Visual Storytellers

Imagine you’re building a beautiful house. You need walls, windows, pictures, and lights to make it feel alive. In React Native, Display Components are exactly that—they’re the building blocks that make your app look amazing!

🏠 The Big Picture

Think of your phone screen as a blank canvas. Display components are like magic paintbrushes that let you:

• Write words (Text)
• Show pictures (Image)
• Create cool backgrounds (ImageBackground)
• Control the top bar (StatusBar)
• Show loading spinners (ActivityIndicator)

Let’s meet each one!

📝 Text Component: Your App’s Voice

What Is It?

The Text component is like a megaphone for your app. Whenever you want to say something to users, you use Text.

Simple Example

import { Text } from 'react-native';

<Text>Hello, World!</Text>

That’s it! You just made your app say “Hello, World!”

Why It Matters

• Everything written on screen uses Text
• Buttons have Text inside
• Labels, titles, paragraphs—all Text!

    A --> D[Labels]

🎨 Text Styling: Making Words Beautiful

What Is It?

Just like you pick clothes for school, you can dress up your text! Colors, sizes, bold—all possible.

The Style Object

<Text style={{
  fontSize: 24,
  color: 'blue',
  fontWeight: 'bold'
}}>
  I'm Big and Blue!
</Text>

Common Style Properties

Real Example

<Text style={{
  fontSize: 18,
  color: '#333',
  fontWeight: '600',
  textAlign: 'center',
  lineHeight: 26
}}>
  Styled text is happy text!
</Text>

✂️ Text Truncation: When Words Don’t Fit

The Problem

Imagine writing a long story on a tiny sticky note. It won’t fit! Same with screens.

The Solution: numberOfLines

<Text numberOfLines={2}>
  This is a very long text that
  will be cut off after two lines
  and show ... at the end
</Text>

How It Works

• Set numberOfLines to limit lines
• React Native adds ... automatically
• No overflow mess!

Example with ellipsizeMode

<Text
  numberOfLines={1}
  ellipsizeMode="tail"
>
  A super long title here...
</Text>

🖼️ Image Component: Picture Perfect

What Is It?

The Image component is like a photo frame for your app. It shows pictures from anywhere!

Three Ways to Use Images

1. Local Images (in your project)

import { Image } from 'react-native';

<Image
  source={require('./photo.png')}
  style={{ width: 100, height: 100 }}
/>

2. Network Images (from internet)

<Image
  source={{ uri: 'https://example.com/cat.jpg' }}
  style={{ width: 200, height: 200 }}
/>

3. Base64 Images (data strings)

<Image
  source={{ uri: 'data:image/png;base64,...' }}
  style={{ width: 50, height: 50 }}
/>

Important Rule ⚠️

Network images MUST have width and height!

Resize Modes

<Image
  source={{ uri: 'https://...' }}
  style={{ width: 200, height: 200 }}
  resizeMode="cover"
/>

    A --> C[Network URL]
    A --> D[Base64 Data]
    B --> E[No size needed]
    C --> F[Size required!]
    D --> F

🌄 ImageBackground Component: The Stage Setter

What Is It?

ImageBackground is like a wallpaper that you can put things ON TOP of!

Why Not Just Image?

• Image: Shows a picture
• ImageBackground: Shows a picture with children on top

Simple Example

import { ImageBackground, Text } from 'react-native';

<ImageBackground
  source={require('./sunset.jpg')}
  style={{ width: 300, height: 200 }}
>
  <Text style={{ color: 'white' }}>
    Hello on top of image!
  </Text>
</ImageBackground>

Real-World Use Case

<ImageBackground
  source={{ uri: 'https://...' }}
  style={{
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center'
  }}
  resizeMode="cover"
>
  <Text style={{
    fontSize: 32,
    color: 'white',
    fontWeight: 'bold'
  }}>
    Welcome!
  </Text>
</ImageBackground>

📊 StatusBar Component: The Control Room

What Is It?

The StatusBar is that thin strip at the very top of your phone—showing time, battery, wifi. You can control it!

Basic Usage

import { StatusBar } from 'react-native';

<StatusBar
  barStyle="dark-content"
/>

Bar Styles

Visual Example

// Light background = dark icons
<StatusBar barStyle="dark-content" />

// Dark background = light icons
<StatusBar barStyle="light-content" />

⚙️ StatusBar Configuration: Full Control

All the Options

<StatusBar
  barStyle="light-content"
  backgroundColor="#6200EE"
  hidden={false}
  animated={true}
  translucent={false}
/>

Property Breakdown

Pro Tip: Use Static Methods

// Hide status bar
StatusBar.setHidden(true);

// Change style dynamically
StatusBar.setBarStyle('light-content');

    B --> H[light-content]

⏳ ActivityIndicator Component: The Waiting Game

What Is It?

The ActivityIndicator is the spinning wheel that tells users “Hold on, something is loading!”

Basic Usage

import { ActivityIndicator } from 'react-native';

<ActivityIndicator />

Customization

<ActivityIndicator
  size="large"
  color="#0000ff"
/>

Sizes Available

Real Example: Loading Screen

const [loading, setLoading] = useState(true);

{loading ? (
  <ActivityIndicator
    size="large"
    color="#6200EE"
  />
) : (
  <Text>Content loaded!</Text>
)}

Common Pattern

import { View, ActivityIndicator } from 'react-native';

<View style={{
  flex: 1,
  justifyContent: 'center',
  alignItems: 'center'
}}>
  <ActivityIndicator
    size="large"
    color="#FF6B6B"
  />
  <Text style={{ marginTop: 10 }}>
    Loading...
  </Text>
</View>

    A[ActivityIndicator] --> B[Shows Spinner]
