React Native for Arcgis 地图开发 LayerManager （五）

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);
  })
