React Native如何以编程方式打开react-native-dropdown-picker

npm install react-native-dropdown-picker

import React from 'react';
import { View, StyleSheet } from 'react-native';
import DropDownPicker from 'react-native-dropdown-picker';

const MyComponent = () => {
  return (
    <View style={styles.container}>
      <DropDownPicker
        items={[
          {label: 'Item 1', value: 'item1'},
          {label: 'Item 2', value: 'item2'},
          {label: 'Item 3', value: 'item3'},
        ]}
        defaultValue="item1"
        containerStyle={{height: 40}}
        style={{backgroundColor: '#fafafa'}}
        dropDownStyle={{backgroundColor: '#fafafa'}}
        onChangeItem={(item) => console.log(item.value)}
      />
    </View>
  );
};

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

export default MyComponent;
