android 百度地图 定位示例

资源内容介绍

1.需要在 http://developer.baidu.com/ 注册开发者(个人或公司)账号 2.需要申请Key 打开网址 http://developer.baidu.com/map/index.php 点击 创建应用,跟流程创建应用app3.点击相关下载->一键下载4.调用百度地图的APP 需要在 AndroidManifest.xml 添加 这里需要添加key,创建应用后，会有这个key ..... package com.obtk.mapdemo;import com.baidu.location.BDLocation;import com.baidu.location.BDLocationListener;import com.baidu.location.LocationClient;import com.baidu.location.LocationClientOption;import com.baidu.mapapi.SDKInitializer;import com.baidu.mapapi.map.BaiduMap;import com.baidu.mapapi.map.BaiduMapOptions;import com.baidu.mapapi.map.MapStatusUpdate;import com.baidu.mapapi.map.MapStatusUpdateFactory;import com.baidu.mapapi.map.MapView;import com.baidu.mapapi.map.MyLocationData;import com.baidu.mapapi.map.MyLocationConfiguration.LocationMode;import com.baidu.mapapi.model.LatLng;import com.baidu.mapapi.search.core.SearchResult;import com.baidu.mapapi.search.geocode.GeoCodeResult;import com.baidu.mapapi.search.geocode.GeoCoder;import com.baidu.mapapi.search.geocode.OnGetGeoCoderResultListener;import com.baidu.mapapi.search.geocode.ReverseGeoCodeOption;import com.baidu.mapapi.search.geocode.ReverseGeoCodeResult;import android.os.Bundle;import android.util.Log;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.RelativeLayout;import android.widget.Toast;import android.app.Activity;import com.obtk.mapdemo.R;public class MapApiDemoActivity extends Activity implements OnGetGeoCoderResultListener {private MapView mMapView = null;private BaiduMap mBaiduMap = null;private GeoCoder mSearch = null;
