The StatusBar
is an integral part of mobile applications, often displaying network indicators, time, and battery information. However, there are scenarios where hiding the StatusBar
is necessary, whether for full-screen experiences, games, or immersive media applications.
In this article, we'll cover how to hide the StatusBar
in React Native, explore various edge cases, and discuss the different requirements based on the design and functionality of your app.
Basic Approach: Hiding the StatusBar
React Native provides the StatusBar
component, which can be used to control its visibility across the app. To completely hide it, you can use the hidden
prop of the StatusBar
component.
Example
import React from 'react';
import { View, StatusBar } from 'react-native';
const App = () => {
return (
<View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
<StatusBar hidden={true} />
{/* Your content goes here */}
</View>
);
};
export default App;
Key Points:
-
Import the
StatusBar
Component: TheStatusBar
component comes fromreact-native
and can be configured within your app's layout. -
Set
hidden={true}
: To hide theStatusBar
, set thehidden
prop totrue
. This will completely hide theStatusBar
for the screen it's applied to.
In this basic example, the StatusBar
is hidden for the entire screen. However, certain edge cases and requirements may require more complex configurations, which we'll discuss next.
Case 1: Full-Screen Applications
For apps that are designed to be full-screen, such as games, media players, or immersive experiences, you’ll likely want to hide the StatusBar
across all screens of your application, and not just on specific ones.
Solution: Global StatusBar Control
To ensure the StatusBar
is hidden across your app:
- Apply the
hidden
prop globally in the root component (e.g.,App.js
). - This will hide the
StatusBar
for all screens, even as users navigate between different parts of the app.
Example for Global StatusBar
import React from 'react';
import { View, StatusBar } from 'react-native';
const App = () => {
return (
<View style={{ flex: 1 }}>
<StatusBar hidden={true} />
{/* Rest of your app goes here */}
</View>
);
};
export default App;
Considerations for Full-Screen Apps
-
No Need for
SafeAreaView
: If you are hiding theStatusBar
, you don’t need to useSafeAreaView
, which normally ensures that your content doesn’t overlap with system UI elements like theStatusBar
or notches on newer devices. Since theStatusBar
is hidden, those concerns no longer apply.
Case 2: Handling Notches and Safe Areas
For apps targeting devices with notches (like iPhones with the notch or Android devices with display cutouts), you usually need to ensure that the app's UI does not overlap with these areas. Normally, SafeAreaView
helps manage this.
Do You Still Need SafeAreaView
?
If you're hiding the StatusBar
completely, you do not need SafeAreaView
for managing safe areas related to the StatusBar
, as it’s no longer visible. However, if your app still needs to account for device notches or other system UI elements like the home indicator, SafeAreaView
might still be useful for managing those areas.
Example with Notch Consideration
import React from 'react';
import { View, StatusBar, SafeAreaView } from 'react-native';
const App = () => {
return (
<SafeAreaView style={{ flex: 1 }}>
<StatusBar hidden={true} />
<View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
{/* Content will not overlap with notches or home indicators */}
</View>
</SafeAreaView>
);
};
export default App;
When to Use SafeAreaView
-
If you hide only the
StatusBar
: If you are only hiding theStatusBar
but still need to avoid overlapping with notches or home indicators, you should useSafeAreaView
. -
If you hide all system UI elements: If your app is truly full-screen, hiding all system UI elements (including the notch or home indicator), you don’t need
SafeAreaView
.
Case 3: StatusBar and Orientation Changes
If your app supports multiple orientations (portrait and landscape), the behavior of the StatusBar
may change based on device settings and orientation. In some cases, the StatusBar
might reappear when switching orientations, especially on Android.
Solution: Lock StatusBar Across Orientations
To ensure the StatusBar
stays hidden across all orientations:
- Monitor orientation changes and programmatically set the
StatusBar
visibility. - Use libraries like
react-native-orientation-locker
to lock the orientation and ensure consistent behavior.
Summary of Key Requirements
-
Completely Hide StatusBar: Use the
hidden={true}
prop on theStatusBar
component to hide it globally or on specific screens. -
Full-Screen Apps: For full-screen apps, remove
SafeAreaView
unless you need to handle notches or home indicators. - Orientation and Edge Cases: Be aware of orientation changes and notch handling for a seamless user experience.
