我正在使用react-native-mapsand构建一个基于位置的 iOS 应用程序react-native-google-places-autocomplete。

在我的代码中，我首先有搜索条形码，然后是地图代码 - 这样搜索栏就会呈现在地图顶部。问题是，我无法移动地图，因为搜索栏组件似乎有一个占据整个屏幕的透明元素。删除搜索栏后，我可以移动地图。如何将搜索栏放在地图顶部并移动地图。

我欢迎替代/更好的方式来做我想做的事情。

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View,
  Dimensions
} from 'react-native';
import MapView from 'react-native-maps';
var {GooglePlacesAutocomplete} = require('react-native-google-places-autocomplete');

const homePlace = {description: 'Home', geometry: { location: { lat: 42.3969, lng: -71.1224 } }};
const workPlace = {description: 'Work', geometry: { location: { lat: 42.3, lng: -71.1 } }};

var screenWidth = Dimensions.get('window').width;

export default class myapp extends Component {
  render() {
    return (
    <View style={styles.container}>


        <MapView
            style={styles.map}

将位置样式添加到react-native-google-places-autocomplete样式属性：

styles={{
          container:{
            position: 'absolute',
            top: 0
          },
            description: {
                fontWeight: 'bold',
            },
          .....
