android - insertMapObject 函数 Android 返回 23 代码 Cartotype

Question

首先，据我所知，Cartotype提供了在Android、iOS等平台提供 map 的API。

从文档中我找到了满足我需要的函数

native int com.cartotype.Framework.insertMapObject  (   int     aMapHandle,
int     aMapObjectType,
String  aLayerName,
Geometry    aGeometry,
String  aStringAttributes,
int     aIntAttribute,
long    aId,
boolean     aReplace 
)       

但是他们引用的参数我无法成功获取，最后得到了

// Second or continuing measurement, add to arrays
// and draw line
iDistanceMeasurementX = extendArray(
iDistanceMeasurementX, thisPoint[0]);
iDistanceMeasurementY = extendArray(
iDistanceMeasurementY, thisPoint[1]);

// _thread.iFramework.deleteMapObjects(0,
// ID_MEASUREMENT_TOOL, ID_MEASUREMENT_TOOL, null);
// _thread.iFramework.addLineOrPolygonObject(
// "measurementtool", iDistanceMeasurementX,
// iDistanceMeasurementY,
// Framework.DEGREE_COORDS, null, 0,
// ID_MEASUREMENT_TOOL, false);


//Drawing line geometry
Geometry geometry = new Geometry(Framework.DEGREE_COORDS);
geometry.appendPoint(thisPoint[0],thisPoint[1]);
geometry.beginContour();

 try {
                                int abc = _thread.iFramework.insertMapObject(0, MapObject.LINE_TYPE, "measurementtool", geometry, null, 0,
                                        ID_MEASUREMENT_TOOL, false);
                                Toast.makeText(getContext(),abc,Toast.LENGTH_SHORT).show();
                            } catch (Exception e) {
                                e.printStackTrace();
                            }

//Drawing line with coordinates
// _thread.iFramework.insertPointMapObject(0,"measurementtool", iDistanceMeasurementX[0],iDistanceMeasurementY[0] ,MapObject.LINE_TYPE, "", 0,
// ID_MEASUREMENT_TOOL, false);
//Toast.makeText(getContext(),"Draw Line ",Toast.LENGTH_SHORT).show();
getMapAndDraw(); // Inefficient, we are drawing

如果根据文档成功，那些“abc”int 返回值 23 并且需要为 0。

我需要画一条 b\w 2 坐标的线

任何帮助将不胜感激

谢谢@Graham

geometry = new Geometry(Framework.DEGREE_COORDS);

   iDistanceMeasurementX = extendArray(
                                    iDistanceMeasurementX, thisPoint[0]);
                            iDistanceMeasurementY = extendArray(
                                    iDistanceMeasurementY, thisPoint[1]);
geometry.appendPoint(iDistanceMeasurementX[iDistanceMeasurementX.length-1], iDistanceMeasurementY[iDistanceMeasurementY.length-1]);

                            //Drawing line geometry

                                _thread.iFramework.insertMapObject(0, MapObject.LINE_TYPE, "measurementtool", geometry, null, 0,
                                        0, false);
