Usage

Expo

If you use Expo, add this lines in your App.js. (It only affects Android)

/* Support Expo */
import { setExpoStatusBarHeight } from 'react-navigation-collapsible';
import { Constants } from 'expo';
setExpoStatusBarHeight(Constants.statusBarHeight);

StackNavigator

(MyScreen.js)

import { withCollapsible } from 'react-navigation-collapsible';
const AnimatedFlatList = Animated.createAnimatedComponent(FlatList);

class MyScreen extends Component{
  static navigationOptions = {
    title: 'Awesome Screen'
  };

  render(){
    const { paddingHeight, scrollY, onScroll } = this.props.collapsible;

    return (
      <AnimatedFlatList 
        ...
        contentContainerStyle={{paddingTop: paddingHeight}}
        _mustAddThis={scrollY}
        onScroll={onScroll} 
        
        // if you want to use 'onScroll' callback.
        // onScroll={Animated.event(
        //   [{nativeEvent: {contentOffset: {y: scrollY}}}],
        //   {useNativeDriver:true, listener:this.onScroll})} 
        />
    )
  }
}

export default withCollapsible(MyScreen, {iOSCollapsedColor: '#031'});

StackNavigator + MaterialTopTabNavigator

(MyScreen.js)

...
export default withCollapsible(MyScreen, {iOSCollapsedColor: '#031'});

(Your Navigator.js)

import { collapsibleOptionsForTab, collapsibleTabConfig } from 'react-navigation-collapsible';

const TopTabNavigator = createMaterialTopTabNavigator(
  {
    Screen1: { screen: MyScreen },
    Screen2: { screen: OtherScreen },
  },
  collapsibleTabConfig({
    navigationOptions:{
      tabBarOptions: {
        indicatorStyle: { backgroundColor: 'white' },
        style: { backgroundColor: 'green' },
      }
    }
  })
);

const routeConfig = {
  MainScreen: { screen: MainScreen },
  TopTabScreen: { screen: TopTabNavigator, navigationOptions: props => collapsibleOptionsForTab(props, {title: 'Material Tab'}) },
};

const StackNavigator = createStackNavigator(routeConfig);

Custom or Image Header with StackNavigator

See Example/src/ImageScreen.js

Extra Header(eg. SearchBar) with StackNavigator

See Example/src/ExtraHeaderScreen.js

API

  • HOC withCollapsible (wrappedUserScreen, ?collapsibleParams: {?iOSCollapsedColor, ?extraHeader, ?extraHeaderStyle})
  • collapsibleOptionsForTab (props, userOptions)
  • collapsibleTabConfig (userConfig)
  • setExpoStatusBarHeight (height)

Limitation

Because react-navigation-capable combines your screen's navigationOptions with {headerTransparent: true}, there is some layout issue on a transition to other screens which is using {headerTransparent: false}.

Tasks

  • [x] Regular Header
  • [x] Image Header
  • [x] Nested Stack+Tab
  • [x] Extra Header
  • [x] HOC
