React Native for Arcgis 地图开发 Lay

针对图层管理LayerManager 比如之前的

{

"LayerId": "要素图层",

"LayerType": "ＭapImageLayer",

"ServerAddr": "https://sampleserver6.arcgisonline.com/arcgis/rest/services/USA/MapServer/0",

"DefineInfo": {

"Opacity": 0.8,

"Priority": 5,

"SubPriority": 10,

"QueryFlag": true,

"LoadFlag": false

}

}

开启图层showLayer

import {LayerManager} from '@haibalai/react-native-arcgis';

LayerManager.showLayer('baseMap', "要素图层")..then((r: any) => {

changeErrorContent('');

changeContent(r);

})

.catch((error: any) => {

changeErrorContent(error);

});

关闭图层hideLayer

import {LayerManager} from '@haibalai/react-native-arcgis';

LayerManager.hideLayer('baseMap', "要素图层"). .then((r: any) => {

changeErrorContent('');

changeContent(r);

})

.catch((error: any) => {

changeErrorContent(error);

});

开启多个图层showLayers

import {LayerManager} from '@haibalai/react-native-arcgis';

LayerManager.showLayers('baseMap', ["要素图层", "要素图层1" ]);

关闭多个图层hideLayers

import {LayerManager} from '@haibalai/react-native-arcgis';

LayerManager.hideLayers('baseMap', ["要素图层", "要素图层1" ]);

设置显示隐藏

```

import {LayerManager} from '@haibalai/react-native-arcgis';

LayerManager.setVisible('baseMap', “要素图层1”, false)

.then((r: any) => {

changeErrorContent('');

changeContent('' + r);

})
