React Native Background Color

This module alows you to set the root backgound color of your react-native app from JS.

This calls setBackgroundColor on the root view, which overwrites/removes any existing background resource, including any borders, corners, padding, etc. This is very good for if you set a splash screen in Android following this popular way - Medium :: Andrey Nikishaev - Change splash screen in React Native Android app. That tutorial recommends setting a solid color on the root view to just cover the splash image. However when the keyboard shows, it shows the background view for a split second, and your splash image is visible. So by using setBackgroundColor from this module, you can erase that image from the back.

Supports only Android at the moment.

Workaround for iOS

You can set the color of the root view directly in the AppDelegate.m file, in the didFinishLaunchingWithOptions function

didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  // ...
  
  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
                                                      moduleName:@"proquantMobile"
                                               initialProperties:nil
                                                   launchOptions:launchOptions]; <--- after this line
  
  // adjust red, green, blue and alpha as per the UIColor spec
  rootView.backgroundColor = [[UIColor alloc] initWithRed:0.23f green:0.25f blue:0.82f alpha:1.0];
  
  // ...
}
