在React Native中，可以在键盘打开时调用onPress

Question

用户需要在点击两次FlatList项目，因为autoFocus={true}对<TextInput。第一次单击时，键盘处于隐藏状态，然后单击呼叫onPress={this.GetItem.bind(this, item)}。是否可以选择GetItem()单击一次而不是单击两次。

export default class App extends Component {
  GetItem (item) {
    console.log(item);
    Alert.alert(item);
  }
  render() {
    return (
      <View style={styles.container}>
        <TextInput
          autoFocus={true}
          style={styles.paragraph}
          keyboardType='web-search'
        >
          Change code in the editor and watch it change on your phone!
          Save to get a shareable url.
        </TextInput>
        <Card title="Local Modules">
          <View>
            <TextInput
              style={styles.searchField}
              placeholder="Type here to translate!"
              onChangeText={(text) => this.setState({text})}
            />

            <FlatList
                data={["akin","alike","close","comparable","like","similar","uniform","Allied","Analogous","Co-ordinate","Commensurate","akin","alike","close","comparable","like","similar","uniform","Allied","Analogous","Co-ordinate","Commensurate"]}
                renderItem={({item}) => (
                  <Text
                    style={styles.listField}
                    onPress={this.GetItem.bind(this, item)}
                    >{item}</Text>
                )}
              />
          </View>
        </Card>
      </View>
    );
  }
}

该组件的目的是在<FlatList>用户搜索时自动提示<TextInput>

添加keyboardShouldPersistTaps='handled'到您的计算机FlatList中将防止键盘被关闭onPress。

<FlatList
    keyboardShouldPersistTaps='handled'
    data={["akin","alike","close","comparable","like","similar","uniform","Allied","Analogous","Co-ordinate","Commensurate","akin","alike","close","comparable","like","similar","uniform","Allied","Analogous","Co-ordinate","Commensurate"]}
    renderItem={({item}) => (
      <Text
        onPress={this.GetItem.bind(this, item)}
        >{item}</Text>
    )}
/>

always也可以作为keyboardShouldPersistTaps价值。
