Android 百度地图定位与覆盖物的添加，以及他们的点击事件。
那个小红点就是覆盖物，小蓝点是定位图标。
(1)百度地图定位的核心代码：
//定位初始化
public void initLocationClient() {
LocationClientOption option = new LocationClientOption();
option.setCoorType(bd09ll);// 返回的定位结果是百度经纬度，默认值gcj02
option.setLocationMode(LocationMode.Hight_Accuracy);// 设置定位模式
// 设置发起定位请求的间隔时间
option.setScanSpan(Iconstants.scanSpan);
option.setOpenGps(true);
option.setIsNeedAddress(true);
option.setAddrType("all");//返回的定位结果包含地址信息
mLocationClient.setLocOption(option);
}
//把定位图标展示在地图上
public void show(){
bMapView = (MapView)layout.findViewById(R.id.bmapView);
mBaiduMap = bMapView.getMap();
mBaiduMap.setMyLocationEnabled(true);// 开启定位图层
mBuilder = new MyLocationData.Builder();
MyLocationData locData = mBuilder
.accuracy(mLocation.getRadius())
// 此处设置开发者获取到的方向信息，顺时针0-360
.direction(mLocation.getDirection())
.latitude(mLocation.getLatitude())
.longitude(mLocation.getLongitude()).build();
mBaiduMap.setMyLocationData(locData);
}
(2)百度地图覆盖物的添加
//通过调用这个方法就能添加覆盖物
public void getMaker(final Bundle bundle){
mSearch.setOnGetGeoCodeResultListener(new OnGetGeoCoderResultListener() {
@Override
public void onGetReverseGeoCodeResult(ReverseGeoCodeResult arg0) {
// TODO Auto-generated method stub
}
@Override
public void onGetGeoCodeResult(GeoCodeResult result) {
// TODO Auto-generated method stub
if (result == null || result.error != SearchResult.ERRORNO.NO_ERROR) {
Log.e(tag, "onGetGeoCodeResult");
Toast.makeText(getActivity(), "抱歉", Toast.LENGTH_LONG).show();
return;
}
addOverlay(bundle);
}
});
}
public void addOverlay(final Bundle bundle){
//先获得你要在地图上添加覆盖物的经纬度
LatLng ll = new LatLng(bundle.getDouble("lat"),bundle.getDouble("lng"));
//在经纬度为ll的地图上添加图标bdA，并设置为不可拖动，还可以携带数据bundle，这个bundle存放有我从json中获取的数据
OverlayOptions ooA = new MarkerOptions().position(ll).icon(bdA)
.draggable(false).extraInfo(bundle);
//覆盖物添加到了地图上
mMarker = (Marker) (mBaiduMap.addOverlay(ooA));
}
(3)定位小图标，与覆盖物的点击事件
//覆盖物的点击
mBaiduMap.setOnMarkerClickListener(new OnMarkerClickListener() {
@Override
public boolean onMarkerClick(final Marker maker) {
// TODO Auto-generated method stub
if (routeOverlay != null ) {
routeOverlay.removeFromMap();
}
Log.e(tag, ">>>>"+maker+"LLLLLLLL"+maker.getExtraInfo());
if(maker.getExtraInfo() == null || maker.getExtraInfo().getString("name") == null){
Log.e(tag, ">>>>"+maker);
}else{
mBaiduMap.hideInfoWindow();
PlanNode stNode = PlanNode.withLocation(new LatLng(AppContext.getInstance().getLatitude(), AppContext.getInstance().getLongitude()));
PlanNode enNode = PlanNode.withLocation(new LatLng(maker.getExtraInfo().getDouble("lat"),maker.getExtraInfo().getDouble("lng")));
mRouteSearch.drivingSearch((new DrivingRoutePlanOption()).from(stNode).to(enNode));
//点击maker弹出的详情框
View view = LayoutInflater.from(getActivity()).inflate(R.layout.show_overlay_info, null);
TextView startTime = (TextView) view.findViewById(R.id.overlay_time_start);
TextView weight = (TextView) view.findViewById(R.id.overlay_weighgt);
TextView volume = (TextView) view.findViewById(R.id.overlay_volume);
TextView type = (TextView) view.findViewById(R.id.overlay_car_type);
TextView count = (TextView) view.findViewById(R.id.tv_count);
int num = 0;
for(String s:listCity){
if(s.equals(maker.getExtraInfo().getString("name"))){
num ++;
}
}
count.setVisibility(View.VISIBLE);
if(num == 1){
count.setVisibility(View.GONE);
}else{
count.setVisibility(View.VISIBLE);
count.setText("("+num+")");
}
startTime.setText(maker.getExtraInfo().getString("requiredSendDt"));
weight.setText(maker.getExtraInfo().getString("weight")+"吨");
volume.setText(maker.getExtraInfo().getString("volume")+"立方");
type.setText(maker.getExtraInfo().getString("typeName"));
LinearLayout intoDetail = (LinearLayout) view.findViewById(R.id.overlay_detail);
mGoodsId = maker.getExtraInfo().getString("id");
LatLng ll = maker.getPosition();
InfoWindow infoWin = new InfoWindow(view, ll, -30 );
mBaiduMap.showInfoWindow(infoWin);
//点击查看当前货源详情
intoDetail.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(getActivity(),GoodsActivity.class);
i.putExtra("city", maker.getExtraInfo().getString("startArea"));
getActivity().startActivity(i);
getActivity().overridePendingTransition(R.anim.slide_in_left,R.anim.fade_in_exit);
mBaiduMap.hideInfoWindow();
if (routeOverlay != null ) {
routeOverlay.removeFromMap();
}
}
});
}
return true;
}
});
//定位小图标的点击事件
mBaiduMap.setOnMyLocationClickListener(new OnMyLocationClickListener() {
@Override
public boolean onMyLocationClick() {
// TODO Auto-generated method stub
UIHelper.showToastsShort("您当前的位置："+AppContext.getInstance().getAddress());
return false;
}
});
