android 使用LocationClient获取精度，纬度坐标

LocationClient类

用来发起定位，添加取消监听

LocationClientOption类

用来设置定位方式，包括是否启用缓存，使用gps，时间间隔等。

BDLocation类

定位结果的封装，包含坐标和错误码等信息。

BDLocationListener接口类

获取定位结果

BDNotifyListener 类

作用：位置提醒接口类，用于设定位置提醒点，以及实现监听函数。这个应该是适用于地图。

1.这是获取经纬度是调用的一个公共方法，实现精度纬度的获取

/**

* 获取精纬度

*

* @return

*/

public static void locate(Application application) {

// 定位服务

LocationClient mLocClient = ((Location)application).mLocationClient;

LocationClientOption option = new LocationClientOption();

option.setOpenGps(true); // 打开gps

// option.setCoorType(mCoorEdit.getText().toString()); // 设置坐标类型

option.setServiceName("com.baidu.location.service_v2.9");

option.setPoiExtraInfo(true);

option.setAddrType("all");

option.setScanSpan(300); // 设置定位模式，小于1秒则一次定位;大于等于1秒则定时定位

if (true) {

option.setPriority(LocationClientOption.NetWorkFirst); // 设置网络优先

} else {

option.setPriority(LocationClientOption.GpsFirst); // 不设置，默认是gps优先

}

option.setPoiNumber(10);

option.disableCache(true);

mLocClient.setLocOption(option);

mLocClient.start();//打开定位

if (mLocClient != null && mLocClient.isStarted()) {

mLocClient.requestLocation();

}

}

2，继承Application的Location类（）

就是值得这个类中的一个mLocationClient变量

package com.example.asmack.location;

import com.baidu.location.*;

import android.app.Application;

import android.util.Log;

import android.widget.TextView;

import android.os.Process;

import android.os.Vibrator;

public class Location extends Application {

// 记录更新弹出框出现的次数

public LocationClient mLocationClient = null;

public MyLocationListenner myListener;

public static String TAG = "LocTestDemo";

@Override

public void onCreate() {

mLocationClient = new LocationClient(this);

myListener = new MyLocationListenner(this, mLocationClient);

mLocationClient.registerLocationListener(myListener);

super.onCreate();

Log.d(TAG, "... Application onCreate... pid=" + Process.myPid());

}

}

3，继承BDLocationListener抽象方法的类MyLocationListenner

该类中需要继承两个方法

/**

* 监听函数，又新位置的时候，格式化成字符串，输出到屏幕中

*/

public class MyLocationListenner implements BDLocationListener {

private Context context;

private LocationClient locationClient;

public MyLocationListenner(Context context, LocationClient locationClient) {

this.context = context;

this.locationClient = locationClient;

}

@Override

public void onReceiveLocation(BDLocation location) {

if (location == null)

return;

StringBuffer sb = new StringBuffer(256);

sb.append("time : ");

sb.append(location.getTime());

sb.append("\nerror code : ");

sb.append(location.getLocType());

sb.append("\nlatitude : ");

sb.append(location.getLatitude());

sb.append("\nlontitude : ");

sb.append(location.getLongitude());

sb.append("\nradius : ");

sb.append(location.getRadius());

if (location.getLocType() == BDLocation.TypeGpsLocation) {

sb.append("\nspeed : ");

sb.append(location.getSpeed());

sb.append("\nsatellite : ");

sb.append(location.getSatelliteNumber());

} else if (location.getLocType() == BDLocation.TypeNetWorkLocation) {

// sb.append("\n省：");

// sb.append(location.getProvince());

// sb.append("\n市：");

// sb.append(location.getCity());

// sb.append("\n区/县：");

// sb.append(location.getDistrict());

sb.append("\naddr : ");

sb.append(location.getAddrStr());

}

String longitude = location.getLongitude() + "";

String latitude = location.getLatitude() + "";

String address = location.getAddrStr();

System.out.println("MyLocationListener location " + "精度 = " + longitude

+ "纬度 = " + latitude + "address = " + address);

}

public void onReceivePoi(BDLocation poiLocation) {

if (poiLocation == null) {

return;

}

StringBuffer sb = new StringBuffer(256);

sb.append("Poi time : ");

sb.append(poiLocation.getTime());

sb.append("\nerror code : ");

sb.append(poiLocation.getLocType());

sb.append("\nlatitude : ");

sb.append(poiLocation.getLatitude());

sb.append("\nlontitude : ");

sb.append(poiLocation.getLongitude());

sb.append("\nradius : ");

sb.append(poiLocation.getRadius());

if (poiLocation.getLocType() == BDLocation.TypeNetWorkLocation) {

sb.append("\naddr : ");

sb.append(poiLocation.getAddrStr());

}

if (poiLocation.hasPoi()) {

sb.append("\nPoi:");

sb.append(poiLocation.getPoi());

} else {

sb.append("noPoi information");

}

Log.d("Location", sb.toString());

}

}
