ReactNative 中整个应用程序的背景图像

Question

In React Native, we have ImageBackground component, that will show the background image in a controller. I want to have same background image for all the controllers. Instead of writing it in all the controllers, is there a way whee I can set the background image for the entire application?

An easy approach is to define one MainComponent which is always the parent view of your screens. You can inject the subviews easily with {this.props.children} .

See simplified example below:

MainComponent :

class MainComponent extends Component {

   render() {

      return (
         <View style ...>
            <ImageBackground .../> 
          {this.props.children}
         </View>
      );
   } 
}

Controller:

import MainComponent from 'yourPATH'

class Controller extends Component {

   render() {
      return (
         <MainComponent>

          //ADD YOUR Regular Controller Screen here. 

         </MainComponent>
      );
   } 
}
