Android百度地图定位收索取周边在列表中展示并选择

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(l
4000
l);
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。
