react-navigation-addon-search-layout

A plain but perfectly acceptable search layout screen that looks good on iOS and Android.

Installation

npm install react-navigation-addon-search-layout

This requires that you have react-native-vector-icons installed in your project, it uses the Ionicons font family. If you use the Expo managed workflow, it will work out of the box as that comes preinstalled and is available through @expo/vector-icons'.

Usage

Here's an example of how you can use this:

import * as React from 'react';
import {
  Animated,
  Button,
  Platform,
  Text,
  StyleSheet,
  View,
} from 'react-native';
import { createAppContainer } from 'react-navigation';
import {
  createStackNavigator,
  StackViewTransitionConfigs,
} from 'react-navigation-stack';
import { RectButton, BorderlessButton } from 'react-native-gesture-handler';
import SearchLayout from 'react-navigation-addon-search-layout';
import { Ionicons } from '@expo/vector-icons';

class HomeScreen extends React.Component {
  static navigationOptions = ({ navigation }) => ({
    title: 'Home',
    headerRight: (
      <BorderlessButton
        onPress={() => navigation.navigate('Search')}
        style={{ marginRight: 15 }}>
        <Ionicons
          name="md-search"
          size={Platform.OS === 'ios' ? 22 : 25}
          color={SearchLayout.DefaultTintColor}
        />
      </BorderlessButton>
    ),
  });

  render() {
    return (
      <View style={styles.container}>
        <Text>Hello there!!!</Text>
      </View>
    );
  }
}

class ResultScreen extends React.Component {
  static navigationOptions = {
    title: 'Result',
  };

  render() {
    return (
      <View style={styles.container}>
        <Text>{this.props.navigation.getParam('text')} result!</Text>
      </View>
    );
  }
}

class SearchScreen extends React.Component {
  static navigationOptions = {
    header: null,
  };

  state = {
    searchText: null,
  };

  _handleQueryChange = searchText => {
    this.setState({ searchText });
  };

  _executeSearch = () => {
    alert('do search!');
  };

  render() {
    let { searchText } = this.state;

    return (
      <SearchLayout
        onChangeQuery={this._handleQueryChange}
        onSubmit={this._executeSearch}>
        {searchText ? (
          <RectButton
            style={{
              borderBottomWidth: StyleSheet.hairlineWidth,
              borderBottomColor: '#eee',
              paddingVertical: 20,
              paddingHorizontal: 15,
            }}
            onPress={() =>
              this.props.navigation.navigate('Result', {
                text: this.state.searchText,
              })
            }>
            <Text style={{ fontSize: 14 }}>{searchText}!</Text>
          </RectButton>
        ) : null}
      </SearchLayout>
    );
  }
}

let SearchStack = createStackNavigator(
  {
    Home: HomeScreen,
    Search: SearchScreen,
  },
  {
    transitionConfig: () => StackViewTransitionConfigs.NoAnimation,
    navigationOptions: {
      header: null,
    },
    defaultNavigationOptions: {
      gesturesEnabled: false,
    },
  }
);

let MainStack = createStackNavigator({
  Feed: SearchStack,
  Result: ResultScreen,
});

export default createAppContainer(MainStack);

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
});
