android获取定位三种方法,Android使用网络获取定位的方法

android获取定位三种⽅法,Android使⽤⽹络获取定位的⽅法本⽂实例为⼤家分享了Android使⽤⽹络获取定位的具体代码，供⼤家参考，具体内容如下

⽬标效果：

程序运⾏弹出权限选择，选择运⾏⽹络定位后会查询位置，然后在TextView上显⽰当前国家和城市。

1.l页⾯定义TextView显⽰城市名。

l页⾯：

xmlns:tools="schemas.android/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:paddingBottom="@dimen/activity_vertical_margin"

android:paddingLeft="@dimen/activity_horizontal_margin"

android:paddingRight="@dimen/activity_horizontal_margin"

android:paddingTop="@dimen/activity_vertical_margin"

tools:context=".MainActivity" >

android:id="@+id/text"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="正在定位。。。" />

2.新建Common.java页⾯，设置公共常量。

Common.java页⾯：

package com.sc.demomon;

/**

* 公共常量

* @author wxy

public class Common {

public static final String LOCATION = "location";

public static final String LOCATION_ACTION = "locationAction";

}

3.新建LocationSvc.java页⾯作为服务进⾏定位。

LocationSvc.java页⾯：

package com.sc.demo.locate;

import com.sc.demomon.Common;

import android.app.Service;

t.Intent;

aoi测试import android.location.Location;

import android.location.LocationListener;

import android.location.LocationManager;

import android.os.Bundle;

import android.os.IBinder;

耐高温毛毡import android.util.Log;

import android.widget.Toast;

/**

* 定位服务

* @author wxy

public class LocationSvc extends Service implements LocationListener {

private LocationManager locationManager;

@Override

public IBinder onBind(Intent intent) {

灌浆剂return null;tz15

}

@Override

public void onCreate() {

locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

@Override

public void onStart(Intent intent, int startId) {

if (Provider(LocationManager.NETWORK_PROVIDER) != null) locationManager

.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,

this);

else if (Provider(LocationManager.GPS_PROVIDER) != null) locationManager

.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,

this);

else Toast.makeText(this, "⽆法定位", Toast.LENGTH_SHORT).show();

}

@Override

public boolean stopService(Intent name) {

return super.stopService(name);

}

@Override

public void onLocationChanged(Location location) {

//通知Activity

Intent intent = new Intent();

intent.setAction(Common.LOCATION_ACTION);

intent.putExtra(Common.LOCATION, String());

sendBroadcast(intent);

// 如果只是需要定位⼀次，这⾥就移除监听，停掉服务。如果要进⾏实时定位，可以在退出应⽤或者其他时刻停掉定位服务。veUpdates(this);

stopSelf();

}

@Override

public void onProviderDisabled(String provider) {

}

@Override

刀模public void onProviderEnabled(String provider) {

}

@Override

public void onStatusChanged(String provider, int status, Bundle extras) {

}

4.MainActivity.java页⾯获取经纬度，然后根据经纬度获取城市名。MainActivity.java页⾯：

package com.sc.demo;

import java.io.IOException;

import java.util.List;

import com.sc.demomon.Common;

import com.sc.demo.locate.LocationSvc;

import android.location.Address;

import android.location.Geocoder;

import android.os.Bundle;

import android.util.Log;

import android.widget.TextView;

import android.app.Activity;

import android.app.ProgressDialog;

t.BroadcastReceiver;

t.Context;

t.Intent;

t.IntentFilter;

public class MainActivity extends Activity {

private TextView text;烷基叔丁基醚

private ProgressDialog dialog;

@Override

protected void onCreate(Bundle savedInstanceState) {

setContentView(R.layout.activity_main);

text = (TextView) findViewById();

// 注册⼴播

IntentFilter filter = new IntentFilter();

filter.addAction(Common.LOCATION_ACTION);

Intent intent = new Intent();

startService(intent);

// 等待提⽰

dialog = new ProgressDialog(this);

dialog.setMessage("正在定位...");

dialog.setCancelable(true);

dialog.show();

}

private class LocationBroadcastReceiver extends BroadcastReceiver { @Override

public void onReceive(Context context, Intent intent) {

if (!Action().equals(Common.LOCATION_ACTION))

return;

String locationInfo = StringExtra(Common.LOCATION); double latitude = Double //截取经纬度转换为double型

.parseDouble(locationInfo.substring(17, 26));

double longitude = Double.parseDouble(locationInfo

.substring(27, 37));

text.setText(getaddress(latitude, longitude));

dialog.dismiss();

MainActivity.this.unregisterReceiver(this);// 不需要时注销

}

public String getaddress(double latitude, double longitude) {

String cityName = "";

List

addList = null;

Geocoder ge = new Geocoder(MainActivity.this);

try {

addList = ge.getFromLocation(latitude, longitude, 1);

} catch (IOException e) {

e.printStackTrace();

}

if (addList != null && addList.size() > 0) {

for (int i = 0; i < addList.size(); i++) {

Address ad = (i);
