Run npm i react-native-splash-screen --save
Second step(Plugin Installation):
Automatic installation
react-native link react-native-splash-screen
or rnpm link react-native-splash-screen
Manual installation
Android:
- In your android/settings.gradle file, make the following additions:
include ':react-native-splash-screen'
project(':react-native-splash-screen').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-splash-screen/android')
- In your android/app/build.gradle file, add the
:react-native-splash-screen
project as a compile-time dependency:
...
dependencies {
...
compile project(':react-native-splash-screen')
}
- Update the MainApplication.java file to use
react-native-splash-screen
via the following changes:
// react-native-splash-screen >= 0.3.1
import org.devio.rn.splashscreen.SplashScreenReactPackage;
// react-native-splash-screen < 0.3.1
import com.cboy.rn.splashscreen.SplashScreenReactPackage;
public class MainApplication extends Application implements ReactApplication {
private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
@Override
protected boolean getUseDeveloperSupport() {
return BuildConfig.DEBUG;
}
@Override
protected List<ReactPackage> getPackages() {
return Arrays.<ReactPackage>asList(
new MainReactPackage(),
new SplashScreenReactPackage() //here
);
}
};
@Override
public ReactNativeHost getReactNativeHost() {
return mReactNativeHost;
}
}
iOS:
-
In XCode, in the project navigator, right click

import android.os.Bundle; // here
import com.facebook.react.ReactActivity;

import org.devio.rn.splashscreen.SplashScreen; // here
// react-native-splash-screen < 0.3.1
import com.cboy.rn.splashscreen.SplashScreen; // here
public class MainActivity extends ReactActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
SplashScreen.show(this); // here
super.onCreate(savedInstanceState);
}

Getting started
Import react-native-splash-screen
in your JS file.
import SplashScreen from 'react-native-splash-screen'
Android:
Create a file called launch_screen.xml
in app/src/main/res/layout
(create the layout
-folder if it doesn't exist). The contents of the file should be the following:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/launch_screen">
</LinearLayout>
Customize your launch screen by creating a launch_screen.png
-file and placing it in an appropriate drawable
-folder. Android automatically scales drawable, so you do not necessarily need to provide images for all phone densities.
You can create splash screens in the following folders:
drawable-ldpi
drawable-mdpi
drawable-hdpi
drawable-xhdpi
drawable-xxhdpi
drawable-xxxhdpi
To modify the status bar color, you can add a color called primary_dark in color.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="primary_dark">#000000</color>
</resources>
Optional steps:
If you want the splash screen to be transparent, follow these steps.
Open android/app/src/main/res/values/styles.xml
and add <item name="android:windowIsTranslucent">true</item>
to the file. It should look like this:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<!--设置透明背景-->
<item name="android:windowIsTranslucent">true</item>
</style>
</resources>
To learn more see examples
If you want to customize the color of the status bar when the splash screen is displayed:
Create android/app/src/main/res/values/colors.xml
and add
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="status_bar_color"><!-- Colour of your status bar here --></color>
</resources>
Create a style definition for this in android/app/src/main/res/values/colors.xml
:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="SplashScreenTheme" parent="SplashScreen_SplashTheme">
<item name="colorPrimaryDark">@color/status_bar_color</item>
</style>
</resources>
Change your show
method to include your custom style:
SplashScreen.show(this, false, R.style.SplashScreenTheme);
iOS
Customize your splash screen via LaunchImage or LaunchScreen.xib,
