class Header extends Component {

constructor(props) {
    super(props);

        <Text >Title</Text>
        <Text>subtitle</Text>
        </View>
    );

I call my Header.js from my main.js

我从main.js调用了我的Header.js

class Main extends Component {

constructor(props) {
    super(props);
}


render() {
    return (
        <Header title = {this.props.navigation.state.params.screen_title} subtitle= {this.props.navigation.state.params.subtitle} />
    );
    }
