arcgis for Android 100.2 绘制点线面（文末有三维地图） arcgis for Android 100.2 加载shp

这是这阶段arcgis for Android 的最后一篇了，前面有三篇。对于我经常使用坐标，进行绘制点线面图形的程序员，这个必须要的。因为在项目中经常用到。

arcgis for Android 100.1 基本操作（缩小放大旋转定位）

                mMapView.getGraphicsOverlays().add(polygonGraphicOverlay);
                break;

        }

    }

}

这里有一个注意就是，画图的用经纬度是在那个坐标系统下面的。一般来说都是使用WGS84坐标。

3、这里看一个三维地图，挺好玩的

实现代码很简单

package com.arcgis.activity;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

import com.arcgis.R;
import com.arcgis.until.TianDiTuMethodsClass;
import com.esri.arcgisruntime.geometry.Point;
import com.esri.arcgisruntime.geometry.SpatialReference;
import com.esri.arcgisruntime.layers.ArcGISSceneLayer;
import com.esri.arcgisruntime.layers.ArcGISTiledLayer;
import com.esri.arcgisruntime.layers.WebTiledLayer;
import com.esri.arcgisruntime.mapping.ArcGISMap;
import com.esri.arcgisruntime.mapping.ArcGISScene;
import com.esri.arcgisruntime.mapping.Basemap;
import com.esri.arcgisruntime.mapping.view.MapView;
import com.esri.arcgisruntime.mapping.view.SceneView;


public class ArcgisThreeDimensionalMapActivity extends AppCompatActivity {
    private SceneView sceneView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_scene);
        sceneView = (SceneView) findViewById(R.id.sceneview);

        ArcGISScene arcGISScene = new ArcGISScene(Basemap.createImagery());

        ArcGISSceneLayer arcGISSceneLayer = new ArcGISSceneLayer(
                "https://services.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer");
        arcGISScene.getOperationalLayers().add(arcGISSceneLayer);
        sceneView.setScene(arcGISScene);
    }


    protected void onResume() {
        super.onResume();
        sceneView.resume();
    }

    @Override
    protected void onPause() {
        super.onPause();
        sceneView.pause();
    }
}

最后还是一样注意权限

还有就是你的编译版本是6.0及以上，需要权限管理，动态加载。

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

到这里就结束吧，稍后我会把这四篇文章的代码打包csdn下载
