Android - 如何获取当前位置(经度和纬度)？

Question

我使用以下代码来获取当前位置即(纬度和经度),但我没有获得当前位置(纬度和经度).

谁知道为什么？

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.Toast;

public class Location_Gps 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)
      {

      }
    }
}

PS:我在manifest文件中使用以下权限:

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

Answer 1

您的清单文件中有错误.正确的是:

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

Answer 2

您必须将位置修复发送到模拟器,因为模拟器是您需要提供的位置修复软件.

如果你正在使用eclipse去

Window -> Show view -> Other

选择Android选项卡并搜索模拟器控件.
在您看到模拟器控制窗口导航到位置控件之后.
如下图所示

发送loc修复后,您可以使用

Location loc = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);

对象在哪里lm,LocationManager所以90%的工作完成;)

干杯!
