React-Native之React Navigation

React Navigation官方地址: https://reactnavigation.org/

设置样式和标题：

  static navigationOptions = {
    title: 'Home', 
    headerStyle: {
      backgroundColor: '#f4511e',
    },
    headerTintColor: '#fff',
    headerTitleStyle: {
      fontWeight: 'bold',
    },
  };

可变Title:

  static navigationOptions = ({ navigation }) => {
    return {
      title: navigation.getParam('otherParam', 'A Nested Details Screen'),
    };
  };

  /* Inside of render() */
  <Button
    title="Update the title"
    onPress={() => this.props.navigation.setParams({otherParam: 'Updated!'})}
  />

统一设置样式

const RootStack = createStackNavigator(
  {
    Home: HomeScreen,
    Details: DetailsScreen,
  },
  {
    initialRouteName: 'Home',
    /* The header config from HomeScreen is now here */
    defaultNavigationOptions: {
      headerStyle: {
        backgroundColor: '#f4511e',
      },
      headerTintColor: '#fff',
      headerTitleStyle: {
        fontWeight: 'bold',
      },
    },
  }
);

可变样式

class DetailsScreen extends React.Component {
  static navigationOptions = ({ navigation, navigationOptions }) => {
    const { params } = navigation.state;

    return {
      title: params ? params.otherParam : 'A Nested Details Screen',
      /* These values are used instead of the shared configuration! */
      headerStyle: {
        backgroundColor: navigationOptions.headerTintColor,
      },
      headerTintColor: navigationOptions.headerStyle.backgroundColor,
    };
  };

  /* render function, etc */
}

自定义TitleView

class LogoTitle extends React.Component {
  render() {
    return (
      <Image
        source={require('./spiro.png')}
        style={{ width: 30, height: 30 }}
      />
    );
  }
}

class HomeScreen extends React.Component {
  static navigationOptions = {
    // headerTitle instead of title
    headerTitle: <LogoTitle />,
  };

  /* render function, etc */
}
