android地图绘制

㈠ android上怎么实现 手绘地图功能

1、获取Android端的坐标、放大系数等参数，回传到服务端绘制好图片和相关数据后回传到Android端.

2、提前准备好图片和数据放到Androd端，然后根据相关参数选择合适的数据和图片。

㈡ android 百度地图上怎么画线，画圆

//代码如下
importandroid.content.Context;
importandroid.graphics.Canvas;
importandroid.graphics.Color;

importcom..mapapi.Overlay;
importcom..mapapi.Projection;

{
privateContextmContext;

@Override
(){
//TODOAuto-generatedmethodstub
returnfalse;
}
privateGeoPointgpoint1,gpoint2,gpoint3;//连线的点
@Override
protectedvoidonCreate(Bundlearg0){
super.onCreate(arg0);
setContentView(R.layout.map_layout);

BaseApplicationbaseApp=(BaseApplication)this.getApplication();
if(baseApp.mBMapManage==null){
baseApp.mBMapManage=newBMapManager(mContext);
baseApp.mBMapManage.init(baseApp.mStrKey,
newBaseApplication.MyGeneralListener());
}
baseApp.mBMapManage.start();
super.initMapActivity(baseApp.mBMapManage);//初始化mapsdk
mapView=(MapView)findViewById(R.id.bmapView);
mapView.setBuiltInZoomControls(true);
//设置在缩放动画过程中也显示overlay,默认为不绘制
mapView.setDrawOverlayWhenZooming(true);

//RouteLinerouteLine=
//(RouteLine)getIntent().getSerializableExtra("routeLine");

//这里画点和连接线
MyOverlaymyOverlay=newMyOverlay();
mapView.getOverlays().add(myOverlay);

MapControllermapController=mapView.getController();
mapController.zoomIn();

gpoint1=newGeoPoint((int)(2259316*10),

gpoint3=newGeoPoint((int)(2259121*10),
(int)(11396066*10));
mapController.animateTo(gpoint1);//设置一个起点
}

classMyOverlayextendsOverlay{

@Override
publicvoiddraw(Canvascanvas,MapViewmapView,booleanshadow){
super.draw(canvas,mapView,shadow);

Projectionprojection=mapView.getProjection();
Pointp1=newPoint();
Pointp2=newPoint();
Pointp3=newPoint();
//经度转像素
projection.toPixels(gpoint1,p1);
projection.toPixels(gpoint2,p2);
projection.toPixels(gpoint3,p3);

//第一个画笔画圆
PaintfillPaint=newPaint();
fillPaint.setColor(Color.BLUE);
fillPaint.setAntiAlias(true);
fillPaint.setStyle(Style.FILL);

//将图画到上层
canvas.drawCircle(p1.x,p1.y,5.0f,fillPaint);
canvas.drawCircle(p2.x,p2.y,5.0f,fillPaint);
canvas.drawCircle(p3.x,p3.y,5.0f,fillPaint);

//第二个画笔画线
Paintpaint=newPaint();
paint.setColor(Color.BLUE);
paint.setDither(true);
paint.setStyle(Paint.Style.STROKE);
paint.setStrokeJoin(Paint.Join.ROUND);
paint.setStrokeCap(Paint.Cap.ROUND);
paint.setStrokeWidth(4);

//连接
Pathpath=newPath();
path.moveTo(p1.x,p1.y);
path.lineTo(p2.x,p2.y);
path.lineTo(p3.x,p3.y);
//画出路径
canvas.drawPath(path,paint);
}
}

}

㈢ 基于android做推箱子游戏，地图如何绘制啊。三层地图 谢谢了，求大神

实在不行就直接opengl

㈣ android 开发使用最新百度地图如何画轨迹

android 使用网络地图画轨迹
