1、注册密钥:地址http://developer.baidu.com/map/

2、下载定位SDK,并导入SDK如图所示:

3.编写MyApplication类

编写MyApplication类,为了使用方便我们可以将实现定位的方法封装的Application组件中

封装下列方法

1、  获取定位信息——requestLocationInfo()

2、  通过广播发送位置信息——sendBroadCast()

3、  停止定位——stopLocationClient()

public class MyApplication extends Application{
    public LocationClient mLocationClient = null;
    public GeofenceClient mGeofenceClient;
    public MyLocationListenner myListener = new MyLocationListenner();
    public static String TAG = "MyApplication";
    private static MyApplication mInstance = null;
    @Override
    public void onCreate(){
        mInstance = this;
        mLocationClient = new LocationClient(this);
        /**
         * 项目的key,自己到官网申请 http://lbsyun.baidu.com/apiconsole/key
         */
        mLocationClient.setAK("你的应用Key");
        mLocationClient.registerLocationListener(myListener);
        mGeofenceClient = new GeofenceClient(this);
        super.onCreate();
        Log.d(TAG, "... Application onCreate... pid=" + Process.myPid());
    }
    
    public static  MyApplication  getInstance(){
        return mInstance;
    }

    /**
     * 停止定位
     */
    public void stopLocationClient(){
        if (mLocationClient != null && mLocationClient.isStarted()){
            mLocationClient.stop();
        } 
    }

    /**
     * 发起定位
     */
    public void requestLocationInfo(){
        setLocationOption();
        if (mLocationClient != null && !mLocationClient.isStarted()){
            mLocationClient.start();
        }
        if (mLocationClient != null && mLocationClient.isStarted()){
            mLocationClient.requestLocation();
        } 
    }

    /**
     *  设置百度地图的相关参数
     */
    private void setLocationOption(){
        LocationClientOption option = new LocationClientOption();
        option.setOpenGps(true); // 打开gps
        option.setCoorType("bd09ll"); // 设置坐标类型
        option.setServiceName("com.baidu.location.service_v2.9");
        option.setPoiExtraInfo(true);
        option.setAddrType("all");
        option.setPoiNumber(10);
        option.disableCache(true);
        mLocationClient.setLocOption(option);
    }

    /**
     * 监听函数,有更新位置的时候,格式化成字符串,输出到屏幕中
     */
    public class MyLocationListenner implements BDLocationListener
    {
        @Override
        public void onReceiveLocation(BDLocation location){
            if (location == null){
                sendBroadCast("定位失败!");
                return;
            }
            sendBroadCast(location.getAddrStr());
        }
        public void onReceivePoi(BDLocation poiLocation){
            if (poiLocation == null){
                sendBroadCast("定位失败!");
                return;
            }
            sendBroadCast(poiLocation.getAddrStr());
        }
    }
    
    /**
     * 得到发送广播
     * @param address
     */
    public void sendBroadCast(String address){
                stopLocationClient();
        Intent intent = new Intent(MainActivity.LOCATION_BCR);
        intent.putExtra("address", address);
        sendBroadcast(intent);
    }
}

4.主程序MainActivity
public class MainActivity extends Activity{
    public static String TAG = "LocTestDemo";
    private BroadcastReceiver broadcastReceiver;
    public static String LOCATION_BCR = "location_bcr";
    private Button locBtn;
    private TextView locInfo;
    private MyApplication application;
    @Override
    protected void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        application=(MyApplication)super.getApplication();
        initialize();
        initializeViews();
        initializeListeners();
    }

    private void initialize(){
        registerBroadCastReceiver();//注册广播
    }
    
    private void initializeViews()
    {
        locBtn = (Button) findViewById(R.id.location);
        locInfo = (TextView) findViewById(R.id.location_info);
    }
    
    private void initializeListeners()
    {
        locBtn.setOnClickListener(new OnClickListener(){
            @Override
            public void onClick(View v){
                locInfo.setText("定位中...");
            //调用请求定位信息
            application.requestLocationInfo();
            }
        });
    }

    /**
     * 注册一个广播,监听定位结果,接受广播获得地址信息
     */
    private void registerBroadCastReceiver()
    {
        broadcastReceiver = new BroadcastReceiver(){
        public void onReceive(Context context, Intent intent){
            String address = intent.getStringExtra("address");
                locInfo.setText(address);
            }
        };
        IntentFilter intentToReceiveFilter = new IntentFilter();
        intentToReceiveFilter.addAction(LOCATION_BCR);
        registerReceiver(broadcastReceiver, intentToReceiveFilter);
    }
    @Override
    protected void onDestroy(){
        super.onDestroy();
        unregisterReceiver(broadcastReceiver);
    }
}
