How to use react-native-autocomplete-input

Tested with RN >= 0.26.2. If you want to use RN < 0.26 try to install react-native-autocomplete-input <= 0.0.5.

Installation

# Install with npm
$ npm install --save react-native-autocomplete-input

# Install with yarn
$ yarn add react-native-autocomplete-input

Example

// ...

render() {
  const { query } = this.state;
  const data = filterData(query);
  return (
    <Autocomplete
      data={data}
      value={query}
      onChangeText={(text) => this.setState({ query: text })}
      flatListProps={{
        keyExtractor: (_, idx) => idx,
        renderItem: ({ item }) => <Text>{item}</Text>,
      }}
    />
  );
}

// ...

Android

Android does not support overflows (#20), for that reason it is necessary to wrap the autocomplete into a absolute positioned view on Android. This will allow the suggestion list to overlap other views inside your component.

//...

render() {
  return(
    <View>
      <View style={styles.autocompleteContainer}>
        <Autocomplete {/* your props */} />
      </View>
      <View>
        <Text>Some content</Text>
      </View>
    </View>
  );
}

//...

const styles = StyleSheet.create({
  autocompleteContainer: {
    flex: 1,
    left: 0,
    position: 'absolute',
    right: 0,
    top: 0,
    zIndex: 1
  }
});

Known issues

• By default the autocomplete will not behave as expected inside a <ScrollView />. Set the scroll view's prop to fix this: keyboardShouldPersistTaps={true} for RN <= 0.39, or keyboardShouldPersistTaps='always' for RN >= 0.40. (#5). Alternatively, you can use renderResultList to render a custom result list that does not use FlatList. See the tests for an example.
• If you want to test with Jest add jest.mock('react-native-autocomplete-input', () => 'Autocomplete'); to your test.
