废话不多说 直接新建一个新android项目：location,然后花一分钟申请一个key,然后就是把百度定位demo抄一下就行
1:首先在AndroidManifest.xml中添加权限
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" >
</uses-permission>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" >
</uses-permission>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" >
</uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" >
</uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" >
</uses-permission>
<uses-permission android:name="android.permission.READ_PHONE_STATE" >
</uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" >
</uses-permission>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" >
</uses-permission>
<uses-permission android:name="android.permission.READ_LOGS" >
</uses-permission>
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
2：在AndroidManifest.xml文件中使用自己写的Application 在application节点中加上一行代码
android:name="com.baidu.baidulocationdemo.LocationApplication"
3:在application节点上 复制如下内容
<service
android:name="com.baidu.location.f"
android:enabled="true"
android:process=":remote" >
<intent-filter>
<action android:name="com.baidu.location.service_v2.2" >
</action>
</intent-filter>
</service>
<!-- meta-data需要写在application中 -->
<meta-data
android:name="com.baidu.lbsapi.API_KEY"
android:value="xAxmR5WgrssC9ATV8gZOvq96" />
在这注意需要把换成自己申请的key
4:配置就算ok了,那么就写代码么,谁叫我们是码农呢? 首先看下自己定义的类MyApplication.java
package com.example.location;
import com.baidu.location.BDLocation;
import com.baidu.location.BDLocationListener;
import com.baidu.location.LocationClient;
import com.baidu.location.Poi;
import android.app.Application;
import android.app.Service;
import android.os.Vibrator;
import android.util.Log;
import android.widget.TextView;
import java.util.List;
public class MyApplication extends Application {
public LocationClient mLocationClient;
public MyLocationListener mMyLocationListener;
public TextView mLocationResult,logMsg;
public TextView trigger,exit;
public Vibrator mVibrator;
@Override
public void onCreate() {
super.onCreate();
mLocationClient = new LocationClient(this.getApplicationContext());
mMyLocationListener = new MyLocationListener();
mLocationClient.registerLocationListener(mMyLocationListener);
mVibrator =(Vibrator)getApplicationContext().getSystemService(Service.VIBRATOR_SERVICE);
}
/**
* 实现实时位置回调监听
*/
public class MyLocationListener implements BDLocationListener {
@Override
public void onReceiveLocation(BDLocation location) {
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){// GPS定位结果
sb.append("\nspeed : ");
sb.append(location.getSpeed());// 单位：公里每小时
sb.append("\nsatellite : ");
sb.append(location.getSatelliteNumber());
sb.append("\nheight : ");
sb.append(location.getAltitude());// 单位：米
sb.append("\ndirection : ");
sb.append(location.getDirection());
sb.append("\naddr : ");
sb.append(location.getAddrStr());
sb.append("\ndescribe : ");
sb.append("gps定位成功");
} else if (location.getLocType() == BDLocation.TypeNetWorkLocation){// 网络定位结果
sb.append("\naddr : ");
sb.append(location.getAddrStr());
//运营商信息
sb.append("\noperationers : ");
sb.append(location.getOperators());
sb.append("\ndescribe : ");
sb.append("网络定位成功");
} else if (location.getLocType() == BDLocation.TypeOffLineLocation) {// 离线定位结果
sb.append("\ndescribe : ");
sb.append("离线定位成功，离线定位结果也是有效的");
} else if (location.getLocType() == BDLocation.TypeServerError) {
sb.append("\ndescribe : ");
sb.append("服务端网络定位失败，可以反馈IMEI号和大体定位时间到[email protected]，会有人追查原因");
} else if (location.getLocType() == BDLocation.TypeNetWorkException) {
sb.append("\ndescribe : ");
sb.append("网络不同导致定位失败，请检查网络是否通畅");
} else if (location.getLocType() == BDLocation.TypeCriteriaException) {
sb.append("\ndescribe : ");
sb.append("无法获取有效定位依据导致定位失败，一般是由于手机的原因，处于飞行模式下一般会造成这种结果，可以试着重启手机");
}
sb.append("\nlocationdescribe : ");// 位置语义化信息
sb.append(location.getLocationDescribe());
List<Poi> list = location.getPoiList();// POI信息
if (list != null) {
sb.append("\npoilist size = : ");
sb.append(list.size());
for (Poi p : list) {
sb.append("\npoi= : ");
sb.append(p.getId() + " " + p.getName() + " " + p.getRank());
}
}
logMsg(sb.toString());
Log.i("BaiduLocationApiDem", sb.toString());
}
}
/**
* 显示请求字符串
* @param str
*/
public void logMsg(String str) {
try {
if (mLocationResult != null)
mLocationResult.setText(str);
} catch (Exception e) {
e.printStackTrace();
}
}
}
这里是直接从百度定位sdk demo中复制过来的,这个不需要去敲,因为它没啥技术和逻辑可言.
5:MainActivity.java
package com.example.location;
import com.baidu.location.LocationClient;
import com.baidu.location.LocationClientOption;
import com.baidu.location.LocationClientOption.LocationMode;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class MainActivity extends Activity {
private TextView tv_locaiton_result;
private LocationClient mLocationClient;
private LocationMode tempMode = LocationMode.Hight_Accuracy;
private String tempcoor="gcj02";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mLocationClient = ((MyApplication)getApplication()).mLocationClient;
tv_locaiton_result = (TextView) findViewById(R.id.tv_locaiton_result);
((MyApplication)getApplication()).mLocationResult = tv_locaiton_result;
initLocation();
}
private void initLocation(){
LocationClientOption option = new LocationClientOption();
option.setLocationMode(tempMode);//可选，默认高精度，设置定位模式，高精度，低功耗，仅设备
option.setCoorType(tempcoor);//可选，默认gcj02，设置返回的定位结果坐标系，
int span=5000;
option.setScanSpan(span);//可选，默认0，即仅定位一次，设置发起定位请求的间隔需要大于等于1000ms才是有效的
option.setOpenGps(true);//可选，默认false,设置是否使用gps
option.setLocationNotify(true);//可选，默认false，设置是否当gps有效时按照1S1次频率输出GPS结果
option.setIgnoreKillProcess(true);//可选，默认true，定位SDK内部是一个SERVICE，并放到了独立进程，设置是否在stop的时候杀死这个进程，默认不杀死
option.setEnableSimulateGps(false);//可选，默认false，设置是否需要过滤gps仿真结果，默认需要
option.setIsNeedLocationDescribe(true);//可选，默认false，设置是否需要位置语义化结果，可以在BDLocation.getLocationDescribe里得到，结果类似于“在北京天安门附近”
option.setIsNeedLocationPoiList(true);//可选，默认false，设置是否需要POI结果，可以在BDLocation.getPoiList里得到
mLocationClient.setLocOption(option);
mLocationClient.start();
}
}
ok，定位就好了 不过这是定位获取到地址,地图上显示 下次弄
