ios - react 原生 : component on top of another component

我正在使用 react-native-maps 构建基于位置的 iOS 应用程序和 react-native-google-places-autocomplete .

在我的代码中,我首先有搜索条形码,然后是 map 代码 - 这样搜索栏就会呈现在 map 顶部。问题是,我无法移动 map ,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 map 。如何将搜索栏放在 map 顶部并移动 map 。

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}
initialRegion={{
latitude: 42.3967,
longitude: -71.1223,
latitudeDelta: 0.0922,
longitudeDelta: 0.0421,
}}>
<MapView.Marker
coordinate={{
latitude: 42.3967,
longitude: -71.1223
}}/>
</MapView>



<GooglePlacesAutocomplete
placeholder='Search location'
minLength={2}
autoFocus={false}
autoCorrect={false}
listViewDisplayed='auto' // true/false/undefined
fetchDetails={true}
renderDescription={(row) => row.description} // custom description render
onPress={(data, details = null) => { // 'details' is provided when fetchDetails = true
console.log(data)
console.log(details)
}}

return ''; // text input default value
}}

styles={{

},
listView: {

}
}}

currentLocation={true}
currentLocationLabel="Current location"

rankby: 'distance',
types: 'food'
}}

filterReverseGeocodingByTypes={['locality', 'administrative_area_level_3', 'sublocality', 'administrative_area_level_2', 'administrative_area_level_1']}
// filter the reverse geocoding results by types - ['locality', 'administrative_area_level_3'] if you want to display only cities

predefinedPlaces={[homePlace, workPlace]}

debounce={200}
//renderLeftButton={() => <Image source={require('left-icon')} />}
renderLeftButton={() => <Text></Text> }
renderRightButton={() => <Text></Text> }


/>


</View>
);
}
}

const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
map: {
left: 0,
right: 0,
top: 0,
bottom: 0,
position: 'absolute'
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
},
});

AppRegistry.registerComponent('myapp', () => myapp);

Component overlay problem

最佳答案

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',
},
.....
