1.获取百度密钥
importandroid.app.Activity;
importandroid.os.Bundle;
importandroid.view.View;
importandroid.view.View.OnClickListener;
importandroid.widget.Button;
importandroid.widget.TextView;importcom.baidu.location.LocationClient;
importcom.baidu.location.LocationClientOption;
importcom.baidu.location.LocationClientOption.LocationMode;publicclass MainActivity extendsActivity{privateLocationClient mLocationClient;//定位SDK的核心类privateTextView LocationResult;privateButton startLocation;@Overrideprotectedvoid onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mLocationClient = ((LocationApplication)getApplication()).mLocationClient;LocationResult = (TextView)findViewById(R.id.textView1);((LocationApplication)getApplication()).mLocationResult = LocationResult;//调用LocationApplication，获得需要的信息startLocation = (Button)findViewById(R.id.addfence);startLocation.setOnClickListener(newOnClickListener() {publicvoid onClick(View v) {InitLocation();//初始化if(startLocation.getText().equals("开启定位")){mLocationClient.start();startLocation.setText("停止定位");}else{mLocationClient.stop();startLocation.setText("开启定位");}}});}@Overrideprotectedvoid onStop() {mLocationClient.stop();super.onStop();}privatevoid InitLocation(){LocationClientOption option = newLocationClientOption();option.setLocationMode(LocationMode.Hight_Accuracy);//设置高精度定位定位模式option.setCoorType("bd09ll");//设置百度经纬度坐标系格式option.setScanSpan(1000);//设置发起定位请求的间隔时间为1000msoption.setIsNeedAddress(true);//反编译获得具体位置，只有网络定位才可以mLocationClient.setLocOption(option);}
}
2定义LocationApplication类：目的是获取信息，定位额关键就靠它了
packagecom.example.getcoord_text;importandroid.app.Application;
importandroid.util.Log;
importandroid.widget.TextView;importcom.baidu.location.BDLocation;
importcom.baidu.location.BDLocationListener;
importcom.baidu.location.LocationClient;publicclass LocationApplication extendsApplication {publicLocationClient mLocationClient;//定位SDK的核心类publicMyLocationListener mMyLocationListener;//定义监听类publicTextView mLocationResult,logMsg;@Overridepublicvoid onCreate() {super.onCreate();mLocationClient = newLocationClient(this.getApplicationContext());mMyLocationListener = newMyLocationListener();mLocationClient.registerLocationListener(mMyLocationListener);}/*** 实现实位回调监听*/publicclass MyLocationListener implementsBDLocationListener {publicvoid onReceiveLocation(BDLocation location) {//Receive Location StringBuffer sb = newStringBuffer(256);
String city=location.getCity();sb.append("time : ");sb.append(location.getTime());//获得当前时间sb.append("\nerror code : ");sb.append(location.getLocType());//获得erro code得知定位现状sb.append("\nlatitude : ");sb.append(location.getLatitude());//获得纬度sb.append("\nlontitude : ");sb.append(location.getLongitude());//获得经度sb.append("\nradius : ");sb.append(location.getRadius());if(location.getLocType() == BDLocation.TypeGpsLocation){//通过GPS定位sb.append("\nspeed : ");sb.append(location.getSpeed());//获得速度sb.append("\nsatellite : ");sb.append(location.getSatelliteNumber());sb.append("\ndirection : ");sb.append("\naddr : ");sb.append(location.getAddrStr());//获得当前地址sb.append(location.getDirection());//获得方位}elseif (location.getLocType() == BDLocation.TypeNetWorkLocation){//通过网络连接定位sb.append("\naddr : ");sb.append(location.getAddrStr());//获得当前地址//运营商信息sb.append("\noperationers : ");sb.append(location.getOperators());//获得经营商？}logMsg(sb.toString());Log.i("BaiduLocationApiDem", sb.toString());}}/*** 显示请求字符串* @param str*/publicvoid logMsg(String str) {try{if(mLocationResult != null)mLocationResult.setText(str); //所有的信息
mLocationResult.setText(city); //只有城市}catch(Exception e) {e.printStackTrace();}}}
3.Mainfast.xml1.在application中加上一个属性nameandroid:name="com.king.salebaby.Location.LocationApplication" //LocationApplication所在的包名2.注册service
<serviceandroid:name="com.baidu.location.f"android:enabled="true"android:process=":remote"android:permission="android.permission.BAIDU_LOCATION_SERVICE" ><intent-filter ><action android:name="com.baidu.location.service_v2.6"></action></intent-filter>
</service>
