具体内容如下效果图:
1、布局文件,就是一个MapView和ListView,布局文件就是上面是一个百度地图的mapview,下面是一个显示周边位置的ListView
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
- android:layout_width="fill_parent"
- android:layout_height="fill_parent"
- android:orientation="vertical" >
- <RelativeLayout
- android:id="@+id/plugin_camera_image_folder_headview"
- android:layout_width="fill_parent"
- android:layout_height="45dp"
- android:layout_marginBottom="3dp"
- android:background="#2B4058"
- android:gravity="center_vertical" >
- <TextView
- android:id="@+id/chat_publish_complete_cancle"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_alignParentLeft="true"
- android:layout_centerVertical="true"
- android:layout_marginLeft="10dp"
- android:text="取消"
- android:textColor="#ffffff"
- android:textSize="16sp" />
- <TextView
- android:id="@+id/chat_publish_complete_title"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_centerInParent="true"
- android:text="选择当前位置"
- android:textColor="#ffffff"
- android:textSize="20sp" />
- <Button
- android:id="@+id/chat_publish_complete_publish"
- android:layout_width="55dp"
- android:layout_height="27dp"
- android:layout_alignParentRight="true"
- android:layout_centerVertical="true"
- android:layout_marginRight="10dp"
- android:background="@drawable/chat_publish_bg"
- android:text="完成"
- android:textColor="#fff"
- android:textSize="16sp" />
- </RelativeLayout>
- <RelativeLayout
- android:layout_width="fill_parent"
- android:layout_height="fill_parent"
- android:layout_weight="2" >
- <com.baidu.mapapi.map.MapView
- android:id="@+id/bmapView"
- android:layout_width="fill_parent"
- android:layout_height="fill_parent"
- android:clickable="true" />
- <Button
- android:id="@+id/request"
- android:layout_width="40dp"
- android:layout_height="40dp"
- android:layout_alignParentBottom="true"
- android:layout_alignParentLeft="true"
- android:layout_marginBottom="40dp"
- android:layout_marginLeft="10dp"
- android:background="@drawable/custom_loc" />
- </RelativeLayout>
- <ListView
- android:id="@+id/lv_location_nearby"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- android:layout_weight="3" />
- </LinearLayout>
2、初始化控件
- <span style="white-space:pre"> </span>dataList = new ArrayList<PoiInfo>();
- mMapView = (MapView) findViewById(R.id.bmapView);
- mCompleteButton = (Button) findViewById(R.id.chat_publish_complete_publish);
- mRequestLocation = (Button) findViewById(R.id.request);
- mListView = (ListView) findViewById(R.id.lv_location_nearby);
- checkPosition=0;
- adapter = new ListAdapter(0);
- mListView.setAdapter(adapter);
3、 定位
- <span style="white-space:pre"> </span>//重新设置
- checkPosition = 0;
- adapter.setCheckposition(0);
- mBaiduMap = mMapView.getMap();
- mBaiduMap.clear();
- // 开启定位图层
- mBaiduMap.setMyLocationEnabled(true);
- mBaiduMap.setMapStatus(MapStatusUpdateFactory.newMapStatus(new MapStatus.Builder().zoom(17).build())); // 设置级别
- // 定位初始化
- mLocationClient = new LocationClient(getApplicationContext()); // 声明LocationClient类
- mLocationClient.registerLocationListener(myListener);// 注册定位监听接口
- /**
- * 设置定位参数
- */
- LocationClientOption option = new LocationClientOption();
- option.setLocationMode(LocationMode.Hight_Accuracy);// 设置定位模式
- // option.setScanSpan(5000);// 设置发起定位请求的间隔时间,ms
- option.setNeedDeviceDirect(true);// 设置返回结果包含手机的方向
- option.setOpenGps(true);
- option.setAddrType("all");// 返回的定位结果包含地址信息
- option.setCoorType("bd09ll");// 返回的定位结果是百度经纬度,默认值gcj02
- option.setIsNeedAddress(true);// 返回的定位结果包含地址信息
- mLocationClient.setLocOption(option);
- mLocationClient.start(); // 调用此方法开始定位
4、定位SDK监听函数
- public class MyLocationListener implements BDLocationListener {
- @Override
- public void onReceiveLocation(BDLocation location) {
- if (location == null || mMapView == null) {
- return;
- }
- locType = location.getLocType();
- Log.i("mybaidumap", "当前定位的返回值是:"+locType);
- longitude = location.getLongitude();
- latitude = location.getLatitude();
- if (location.hasRadius()) {// 判断是否有定位精度半径
- radius = location.getRadius();
- }
- if (locType == BDLocation.TypeNetWorkLocation) {
- addrStr = location.getAddrStr();// 获取反地理编码(文字描述的地址)
- Log.i("mybaidumap", "当前定位的地址是:"+addrStr);
- }
- direction = location.getDirection();// 获取手机方向,【0~360°】,手机上面正面朝北为0°
- province = location.getProvince();// 省份
- city = location.getCity();// 城市
- district = location.getDistrict();// 区县
- LatLng ll = new LatLng(location.getLatitude(),location.getLongitude());
- //将当前位置加入List里面
- PoiInfo info = new PoiInfo();
- info.address = location.getAddrStr();
- info.city = location.getCity();
- info.location = ll;
- info.name = location.getAddrStr();
- dataList.add(info);
- adapter.notifyDataSetChanged();
- Log.i("mybaidumap", "province是:"+province +" city是"+city +" 区县是: "+district);
- // 构造定位数据
- MyLocationData locData = new MyLocationData.Builder()
- .accuracy(location.getRadius())
- // 此处设置开发者获取到的方向信息,顺时针0-360
- .direction(100).latitude(location.getLatitude())
- .longitude(location.getLongitude()).build();
- mBaiduMap.setMyLocationData(locData);
- //画标志
- CoordinateConverter converter = new CoordinateConverter();
- converter.coord(ll);
- converter.from(CoordinateConverter.CoordType.COMMON);
- LatLng convertLatLng = converter.convert();
- OverlayOptions ooA = new MarkerOptions().position(ll).icon(BitmapDescriptorFactory.fromResource(R.drawable.icon_marka));
- mCurrentMarker = (Marker) mBaiduMap.addOverlay(ooA);
- MapStatusUpdate u = MapStatusUpdateFactory.newLatLngZoom(convertLatLng, 17.0f);
- mBaiduMap.animateMapStatus(u);
- //画当前定位标志
- MapStatusUpdate uc = MapStatusUpdateFactory.newLatLng(ll);
- mBaiduMap.animateMapStatus(uc);
- mMapView.showZoomControls(false);
- //poi 搜索周边
- new Thread(new Runnable() {
- @Override
- public void run() {
- // TODO Auto-generated method stub
- Looper.prepare();
- searchNeayBy();
- Looper.loop();
- }
- }).start();
- }
5、搜索周边:
- private void searchNeayBy(){
- // POI初始化搜索模块,注册搜索事件监听
- mPoiSearch = PoiSearch.newInstance();
- mPoiSearch.setOnGetPoiSearchResultListener(this);
- PoiNearbySearchOption poiNearbySearchOption = new PoiNearbySearchOption();
- poiNearbySearchOption.keyword("公司");
- poiNearbySearchOption.location(new LatLng(latitude, longitude));
- poiNearbySearchOption.radius(100); // 检索半径,单位是米
- poiNearbySearchOption.pageCapacity(20); // 默认每页10条
- mPoiSearch.searchNearby(poiNearbySearchOption); // 发起附近检索请求
- }
7、周边地理位置结果返回
- @Override
- public void onGetPoiResult(PoiResult result) {
- // 获取POI检索结果
- if (result == null || result.error == SearchResult.ERRORNO.RESULT_NOT_FOUND) {// 没有找到检索结果
- Toast.makeText(MainActivity.this, "未找到结果",Toast.LENGTH_LONG).show();
- return;
- }
- if (result.error == SearchResult.ERRORNO.NO_ERROR) {// 检索结果正常返回
- // mBaiduMap.clear();
- if(result != null){
- if(result.getAllPoi()!= null && result.getAllPoi().size()>0){
- dataList.addAll(result.getAllPoi());
- // adapter.notifyDataSetChanged();
- Message msg = new Message();
- msg.what = 0;
- handler.sendMessage(msg);
- }
- }
- }
- }
8、返回结果result.getAllPoi() 设到ListView的Adapter里面去,刷新控件即可。
