百度地图BaiduMapsApiASDemo自定义绘制功能总结

在地图上用GraphicsOverlay添加点、线、多边形、圆，并对Polyline进行点击事件响应

*1. 添加普通折线绘制

LatLng p1 = new LatLng(39.97923, 116.357428);
LatLng p2 = new LatLng(39.94923, 116.397428);
LatLng p3 = new LatLng(39.97923, 116.437428);
List points = new ArrayList();
points.add(p1);
points.add(p2);
points.add(p3);
OverlayOptions ooPolyline = new PolylineOptions().width(10)
.color(0xAAFF0000).points(points);
mPolyline = (Polyline) mBaiduMap.addOverlay(ooPolyline);
*2 添加多颜色分段的折线绘制

LatLng p11 = new LatLng(39.965, 116.444);
LatLng p21 = new LatLng(39.925, 116.494);
LatLng p31 = new LatLng(39.955, 116.534);
LatLng p41 = new LatLng(39.905, 116.594);
LatLng p51 = new LatLng(39.965, 116.644);
List points1 = new ArrayList();
points1.add(p11);
points1.add(p21);
points1.add(p31);
points1.add(p41);
points1.add(p51);
List colorValue = new ArrayList();
colorValue.add(0xAAFF0000);
colorValue.add(0xAA00FF00);
colorValue.add(0xAA0000FF);
OverlayOptions ooPolyline1 = new PolylineOptions().width(10)
.color(0xAAFF0000).points(points1).colorsValues(colorValue);
mColorfulPolyline = (Polyline) mBaiduMap.addOverlay(ooPolyline1);
*3 添加多纹理分段的折线绘制

BitmapDescriptor mRedTexture = BitmapDescriptorFactory.fromAsset(“icon_road_red_arrow.png”);
BitmapDescriptor mBlueTexture = BitmapDescriptorFactory.fromAsset(“icon_road_blue_arrow.png”);
BitmapDescriptor mGreenTexture = BitmapDescriptorFactory.fromAsset(“icon_road_green_arrow.png”);

LatLng p111 = new LatLng(39.865, 116.444);    LatLng p211 = new LatLng(39.825, 116.494);    LatLng p311 = new LatLng(39.855, 116.534);    LatLng p411 = new LatLng(39.805, 116.594);    List<LatLng> points11 = new ArrayList<LatLng>();    points11.add(p111);    points11.add(p211);    points11.add(p311);    points11.add(p411);    List<BitmapDescriptor> textureList = new ArrayList<BitmapDescriptor>();    textureList.add(mRedTexture);    textureList.add(mBlueTexture);    textureList.add(mGreenTexture);    List<Integer> textureIndexs = new ArrayList<Integer>();    textureIndexs.add(2);    textureIndexs.add(0);    textureIndexs.add(1);    OverlayOptions ooPolyline11 = new PolylineOptions().width(20)            .points(points11).dottedLine(true).customTextureList(textureList).textureIndex(textureIndexs);mTexturePolyline = (Polyline) mBaiduMap.addOverlay(ooPolyline11);

4 添加弧线

OverlayOptions ooArc = new ArcOptions().color(0xAA00FF00).width(8) .points(p1, p2, p3); mBaiduMap.addOverlay(ooArc);

5 添加圆 LatLng llCircle = new LatLng(39.90923, 116.447428); OverlayOptions ooCircle = new CircleOptions().fillColor(0x000000FF) .center(llCircle).stroke(new Stroke(5, 0xAA000000)) .radius(1400); mBaiduMap.addOverlay(ooCircle)；

6 添加点

LatLng llDot = new LatLng(39.98923, 116.397428); OverlayOptions ooDot = new DotOptions().center(llDot).radius(6) .color(0xFF0000FF); mBaiduMap.addOverlay(ooDot);

7 添加多边形

LatLng pt1 = new LatLng(39.93923, 116.357428);
LatLng pt2 = new LatLng(39.91923, 116.327428);
LatLng pt3 = new LatLng(39.89923, 116.347428);
LatLng pt4 = new LatLng(39.89923, 116.367428);
LatLng pt5 = new LatLng(39.91923, 116.387428);
List pts = new ArrayList();
pts.add(pt1);
pts.add(pt2);
pts.add(pt3);
pts.add(pt4);
pts.add(pt5);
OverlayOptions ooPolygon = new PolygonOptions().points(pts)
.stroke(new Stroke(5, 0xAA00FF00)).fillColor(0xAAFFFF00);
mBaiduMap.addOverlay(ooPolygon);
8 添加文字
LatLng llText = new LatLng(39.86923, 116.397428);
OverlayOptions ooText = new TextOptions().bgColor(0xAAFFFF00)
.fontSize(24).fontColor(0xFFFF00FF).text(“百度地图SDK”).rotate(-30).position(llText);
mBaiduMap.addOverlay(ooText);
9 对Polyline进行点击事件响应
mBaiduMap.setOnPolylineClickListener(new BaiduMap.OnPolylineClickListener() {
@Override
public boolean onPolylineClick(Polyline polyline) {
if (polyline == mPolyline) {
polyline.setWidth( 20 );
} else if (polyline == mColorfulPolyline) {
polyline.remove();
} else if (polyline == mTexturePolyline) {
Toast.makeText( getApplicationContext(), “点数：” + polyline.getPoints().size()
+ “,width:” + polyline.getWidth(),
Toast.LENGTH_SHORT).show();
}
return false;
}
});
