Example

// ...

render() {
  const { query } = this.state;
  const data = this._filterData(query);
  return (
    <Autocomplete
      data={data}
      defaultValue={query}
      onChangeText={text => this.setState({ query: text })}
      renderItem={({ item, i }) => (
        <TouchableOpacity onPress={() => this.setState({ query: item })}>
          <Text>{item}</Text>
        </TouchableOpacity>
      )}
    />
  );
}

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).
If you want to test with Jest add jest.mock('react-native-autocomplete-input', () => 'Autocomplete'); to your test.
