我试图在地图上放置一个位置图标,有时重新加载后,该图标离开了应该包裹的容器。以下是我所指的图像,任何人都可以帮忙。 / p>
下面是我的代码
<MapView
style={map}
region={region}
showsUserLocation
loadingEnabled
showsCompass
showsTraffic
onRegionChangeComplete={this.onRegionChangeComplete}
onRegionChange={this.onRegionChange}
ref={el => (this.mapView = el)}
>
<Fragment>
<LocationButton
onPress={this.refocus}
style={locationFocus}
/>
</Fragment>
</MapView>
)}
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
},
map: {
position: 'absolute',
flex: 1,
width: '100%',
height: '100%',
},
locationFocus: {
position: 'absolute',
bottom: 200,
right: 20,
}
});
答案 0 :(得分:1)
从MapView容器中删除“ LocationButton”并添加主容器中
<View style={{flex:1}}>
<MapView
style={map}
region={region}
showsUserLocation
loadingEnabled
showsCompass
showsTraffic
onRegionChangeComplete={this.onRegionChangeComplete}
onRegionChange={this.onRegionChange}
ref={el => (this.mapView = el)}
>
</MapView>
<Fragment>
<LocationButton
onPress={this.refocus}
style={locationFocus}
/>
</Fragment>
</View>
