百度地图实现定位功能及城市选择

由于项目需要于是单独抽出了一点时间实现了这个功能，目前效果还不错，应该可以满足大多数的需求。下面图片是UI效果图：

1，实现该效果首先需要集成百度地图sdk ，主要集成基础定位，室内定位，基础地图，检索功能，计算工具等模块sdk。具体的集成方式参考此处点击打开链接

2，百度地图集成成功之后就可以开始地图的开发了

地图模块

首先是布局的构建，新建布局文件fragment_shopstore.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:background="@color/white"android:orientation="vertical"tools:context="com.first.mzystore.home.fragment.ClassifyFragment"><RelativeLayoutandroid:layout_width="match_parent"android:layout_height="?actionBarSize"android:paddingLeft="15dp"android:paddingRight="15dp"android:orientation="horizontal"><TextViewandroid:id="@+id/tv_poi_city"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="杭州"android:layout_alignParentLeft="true"android:textSize="@dimen/text_size_14"android:layout_centerVertical="true"android:textColor="@color/c_333333"android:drawableLeft="@mipmap/location"/><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:text="附近门店"android:layout_centerInParent="true"android:layout_centerVertical="true"android:textSize="@dimen/text_size_title"android:textColor="@color/c_333333"android:textStyle="bold" /><TextViewandroid:id="@+id/tv_search"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="查看附近门店"android:layout_alignParentRight="true"android:textSize="@dimen/text_size_14"android:layout_centerVertical="true"android:textColor="@color/blue" /></RelativeLayout><com.baidu.mapapi.map.MapViewandroid:id="@+id/mmap"android:layout_width="match_parent"android:layout_height="match_parent" ></com.baidu.mapapi.map.MapView></LinearLayout>

接下来就是控件的初始化：

GeoCoder mSearch = null; // 搜索模块，也可去掉地图模块独立使用

// 定位相关

LocationClient mLocClient;

//定位监听
public MyLocationListenner myListener = new MyLocationListenner();

protected void findViews(View view) {
mMapView = (MapView) view.findViewById(R.id.mmap)；
tvSearch = view.findViewById(R.id.tv_search);

tvPoiCity = view.findViewById(R.id.tv_poi_city);

}

//初始化地图信息

mBaiduMap = mMapView.getMap();
mBaiduMap.setMapType(BaiduMap.MAP_TYPE_NORMAL);
mBaiduMap.setBuildingsEnabled(false);//设置是否展示3d效果

mMapView.showZoomControls(false);

// 开启定位图层
mBaiduMap.setMyLocationEnabled(true);

// 初始化搜索模块，注册事件监听
mSearch = GeoCoder.newInstance();

mSearch.setOnGetGeoCodeResultListener(listener);

/**
* 定位SDK监听函数
*/
public class MyLocationListenner implements BDLocationListener {
@Override
public void onReceiveLocation(BDLocation location) {
// map view 销毁后不在处理新接收的位置
if (location == null || mMapView == null) {
return;
}
mlocation = location;
if(location.getCity()!=null) {
cityName = location.getCity().replace("市", "");
}
myCityName = cityName;
Log.w("--------",location.getAddrStr());
MyLocationData locData = new MyLocationData.Builder()
.accuracy(mlocation.getRadius())
// 此处设置开发者获取到的方向信息，顺时针0-360
.direction(100).latitude(mlocation.getLatitude())
.longitude(mlocation.getLongitude()).build();
mBaiduMap.setMyLocationData(locData);
if (isFirstLoc) {
isFirstLoc = false;
LatLng ll = new LatLng(location.getLatitude(),
location.getLongitude());
MapStatus.Builder builder = new MapStatus.Builder();
builder.target(ll).zoom(13.0f);
mBaiduMap.animateMapStatus(MapStatusUpdateFactory.newMapStatus(builder.build()));
setLocation();
}
if (mLocClient.isStarted()) {
// 获得位置之后停止定位
mLocClient.stop();
}
}
public void onReceivePoi(BDLocation poiLocation) {

}
}

//选择其他城市需要用到百度地图的反编码功能实现地理编码检索回调

// 创建地理编码检索
OnGetGeoCoderResultListener listener = new OnGetGeoCoderResultListener() {

public void onGetGeoCodeResult(GeoCodeResult result) {
//编码检索根据传入的城市和详细地址可以定位到某个城市
Log.w("----ERRORNO---",result.error+"");
if (result == null || result.error != SearchResult.ERRORNO.NO_ERROR) {

Toast.makeText(getActivity(), "抱歉，未能找到结果", Toast.LENGTH_LONG)
.show();
return;
}
// 下面是添加检索结果的marker点可以根据需要自己选是否显示
// mBaiduMap.clear();
// mBaiduMap.addOverlay(new MarkerOptions().position(result.getLocation())
// .icon(BitmapDescriptorFactory
// .fromResource(R.mipmap.icon_marka)));
// mBaiduMap.setMapStatus(MapStatusUpdateFactory.newLatLng(result
// .getLocation()));
//获取地理编码结果
}

@Override
public void onGetReverseGeoCodeResult(ReverseGeoCodeResult result) {
//反编码检索根据传入的经纬度可以定位到某个城市
if (result == null || result.error != SearchResult.ERRORNO.NO_ERROR) {
Toast.makeText(getActivity(), "抱歉，未能找到结果", Toast.LENGTH_LONG)
.show();
return;
}

// 下面是添加检索结果的marker点可以根据需要自己选是否显示
// mBaiduMap.clear();
// mBaiduMap.addOverlay(new MarkerOptions().position(result.getLocation())
// .icon(BitmapDescriptorFactory
// .fromResource(R.mipmap.icon_marka)));
mBaiduMap.setMapStatus(MapStatusUpdateFactory.newLatLng(result
.getLocation()));
if(cityName.equals("上海")) {
setNewLocation(list2);
}else if(cityName.equals("北京")){
setNewLocation(list3);
}
}

};

在城市选择之后回到地图页面时调用下面方法：

需要传入城市的经纬度，后续会附上相关json文件

mSearch.reverseGeoCode(new ReverseGeoCodeOption().location(latLng).newVersion(1));
