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">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:paddingLeft="15dp"
android:paddingRight="15dp"
android:orientation="horizontal">
<TextView
android: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"/>
<TextView
android: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" />
<TextView
android: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.MapView
android: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();
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);
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));
