我在Android上工作。我制作了一个获取经纬度的程序。我如何获得我的Android设备的经度和纬度
这是我的计划
package com.ram.currentlocation;
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.TextView;
import android.widget.Toast;
public class Location_Gps extends Activity
{
TextView ll;
TextView lt;
static double lati;
static double longi;
/** 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.NETWORK_PROVIDER, 0, 0, mlocListener);
}
/* Class My Location Listener */
public class MyLocationListener implements LocationListener
{
@Override
public void onLocationChanged(Location loc)
{
lati= loc.getLatitude();
longi=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)
{
}
public Location_Gps getLocationCordinates()
{
Location_Gps location_Gps =new Location_Gps();
return location_Gps;
}
}
//---
}
但对于第一次给纬度和经度0,0。每当我移动我的设备时,它会给出一些要点。请建议我第一次得到坐标时应该做些什么。
任何人都可以更改我的上述程序来纠正..? –
