1.初始化地图
//初始化地图
private void initMapView() {
//1.获取地图控件引用
mMapView = findViewById(R.id.bmapView);
mBaidumap = mMapView.getMap();
//2.设置初始定位点在上海
GEO_SHANGHAI = new LatLng(31.227, 121.481);
GEO_BEIJING = new LatLng(39.963175, 116.400244);
mBaidumap.setMapStatus(MapStatusUpdateFactory.newLatLng(GEO_SHANGHAI));
//3.设置地图比例尺，14级。比例尺为1000m(百度地图暂时只能放大到100m)
mBaidumap.setMapStatus(MapStatusUpdateFactory.zoomTo(13));
}
2.用户输入地址获取经纬度

3.批量放置标记点
(1)标记点介绍
点标记用来在地图上标记任何位置，例如用户位置、车辆位置、店铺位置等一切带有位置属性的事物。
(2)java代码
//定义Maker坐标点
LatLng point = new LatLng(39.963175, 116.400244);
LatLng point1 = new LatLng(39.967175, 116.402244);
LatLng point2 = new LatLng(39.965175, 116.404244);
LatLng point3 = new LatLng(39.969175, 116.408244);
LatLng point4 = new LatLng(39.960175, 116.406244);
ArrayList<LatLng> pointList=new ArrayList<>();
pointList.add(point);
pointList.add(point1);
pointList.add(point2);
pointList.add(point3);
pointList.add(point4);
for (int i = 0; i <pointList.size() ; i++) {
//构建Marker图标
BitmapDescriptor bitmap = BitmapDescriptorFactory
.fromResource(R.mipmap.icon_gcoding);
//构建MarkerOption，用于在地图上添加Marker
OverlayOptions option = new MarkerOptions()
.position(pointList.get(i))
.icon(bitmap);
//在地图上添加Marker，并显示
mBaidumap.addOverlay(option);
}
