Android系统上，使用百度地图SDK获得当前设备位置所在的省、市、区、街道、经纬度。

一、Java 代码

package com.hxzy.baidumap;import java.util.List;import com.baidu.location.BDLocation;import com.baidu.location.BDLocationListener;import com.baidu.location.LocationClient;import com.baidu.location.LocationClientOption;import android.app.Activity;import android.os.Bundle;import android.widget.Toast;public class MainActivity extends Activity {private LocationClient mLocationClient = null;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);// setContentView(R.layout.activity_main);MyLocationListenner myListener = new MyLocationListenner();mLocationClient = new LocationClient(this);LocationClientOption option = new LocationClientOption();option.setIsNeedAddress(true);option.setAddrType("all");mLocationClient.setLocOption(option);mLocationClient.registerLocationListener(myListener);mLocationClient.start();}@Overridepublic void onDestroy() {mLocationClient.stop();super.onDestroy();}private class MyLocationListenner implements BDLocationListener {@Overridepublic void onReceiveLocation(BDLocation location) {String province = location.getProvince();String city = location.getCity();String district = location.getDistrict();String street = location.getStreet();double longitude = location.getLongitude();double latifude = location.getLatitude();Toast.makeText(MainActivity.this,province + "," + city + "," + district + "," + "," + street + "," + longitude + "," + latifude,Toast.LENGTH_LONG).show();}}}

二、manifest.xml

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.hxzy.baidumap"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="14"        android:targetSdkVersion="21" />    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="com.hxzy.baidumap.MainActivity"            android:label="@string/app_name" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>        <service            android:name="com.baidu.location.f"            android:enabled="true"            android:process=":remote" >        </service>                <meta-data            android:name="com.baidu.lbsapi.API_KEY"            android:value="BKqClcqTEZ8YZEIzzYDtkp8m" />          </application>    <!-- 这个权限用于进行网络定位 -->    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" >    </uses-permission>    <!-- 这个权限用于访问GPS定位 -->    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" >    </uses-permission>    <!-- 用于访问wifi网络信息，wifi信息会用于进行网络定位 -->    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" >    </uses-permission>    <!-- 获取运营商信息，用于支持提供运营商信息相关的接口 -->    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" >    </uses-permission>    <!-- 这个权限用于获取wifi的获取权限，wifi信息会用来进行网络定位 -->    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" >    </uses-permission>    <!-- 用于读取手机当前的状态 -->    <uses-permission android:name="android.permission.READ_PHONE_STATE" >    </uses-permission>    <!-- 写入扩展存储，向扩展卡写入数据，用于写入离线定位数据 -->    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" >    </uses-permission>    <!-- 访问网络，网络定位需要上网 -->    <uses-permission android:name="android.permission.INTERNET" />    <!-- SD卡读取权限，用户写入离线定位数据 -->    <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" >    </uses-permission></manifest>
