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];
// ...
}
