Question

我想在一个字符串中将latitud，Longitud存储在gps中，这样我就可以使用开放套接字将每个更改位置发送到我的新位置！所以任何帮助，以节省这个纬度和纵向！这是我的代码

package letget.h;

import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.widget.Toast;

public class letget extends Activity
{
  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState)
  {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    /* Use the LocationManager class to obtain GPS locations */
    LocationManager mlocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
    LocationListener mlocListener = new MyLocationListener();
    mlocManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, 0, mlocListener);
  }

  /* Class My Location Listener */
  public class MyLocationListener implements LocationListener
  {
    @Override
    public void onLocationChanged(Location loc)
    {
      loc.getLatitude();
      loc.getLongitude();
      String Text = "My current location is: " +
                    "Latitud ="+ loc.getLatitude() +
                    "Longitud =" + loc.getLongitude();
      Toast.makeText( getApplicationContext(),
                      Text,
                      Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onProviderDisabled(String provider)
    {
      Toast.makeText( getApplicationContext(),
                      "Gps Disabled",
                      Toast.LENGTH_SHORT ).show();
    }

    @Override
    public void onProviderEnabled(String provider)
    {
       Toast.makeText( getApplicationContext(),
                       "Gps Enabled",
                       Toast.LENGTH_SHORT).show();
    }

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

    }

  }/* End of Class MyLocationListener */

}/* End of UseGps Activity*/

Answer 1

你需要

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

在您的AndroidManifest.xml中访问GPS位置。

获取字符串的代码对我来说是正确的。要将其发送到套接字，您需要添加

import java.net.*

然后，假设您的python服务器正在侦听端口上的命令，请执行类似

的操作

String cmd("[THE COMMAND TO SEND]");

InetSocketAddress address = new InetSocketAddress("[YOUR_URL]", [YOUR_PORT]);
DatagramPacket request = new DatagramPacket(cmd.getBytes(), cmd.length(), address);
DatagramSocket socket = new DatagramSocket();
socket.send(request);

（捕获Socket和IO异常）。发送命令显然取决于另一端的python脚本正在侦听的内容。您还可以使用类似HTTPConnection的内容并将值发布到它。

Answer 2

您还需要将loc.getLatitude从double转换为字符串。 Double.toString（loc.getLatitude（））;

android纬度和经度
