Android - 如何获取当前位置（纬度和经度）？
我使用以下代码来获取当前位置（纬度和经度），但我没有获取当前位置（纬度和经度）。
有人知道为什么吗？
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"/>
I am using the following code to get the current location namely (latitude and longitude), but I am not getting current location (latitude and longitude).
Anyone knows why?
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)
{
}
}
}
P.S.: I am using the following permissions in the manifest file:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_CORSE_LOCATION"/>

您的清单文件中有错误。正确的一项是：
You have a mistake in your manifest file. Correct one is:
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位置修复的软件。
如果您使用的是 Eclipse，请转到
Window ->显示视图->其他选择 Android 选项卡并搜索模拟器控件。
看到模拟器控制窗口后，导航到位置控件。
如下图所示
发送 loc 修复后，您可以使用
Where
lm是LocationManager对象，因此 90% 的工作已完成；）干杯！
You have to send location fix to emulator,as emulator is software you need to provide with location fix.
If you are using eclipse go to
Window -> Show view -> OtherSelect Android tab and search for emulator control.
After u see emulator control window navigate to location controls.
As u see in below pic
After you have sent loc fix you can use
Where
lmisLocationManagerobject so 90% of work is done ;)Cheers!
在你的android清单中你设置了权限吗？
就仅获得 (0,0) 坐标而言，您可能正在使用模拟器。如果您使用的是 eclipse，请转到模拟器控件，在底部您可以将假坐标发送到设备
In your android manifest did you set the permissions?
As far as only getting (0,0) co-ords you're probably using the emulator. If you're using eclipse go to the emulator control and at the bottom you can send the fake co-ords to the device
您没有使用正确的权限。正确的是：
顺便说一句，您的需求只能通过以下方式满足：
所以不需要
ACCESS_COARSE_LOCATIONYou are not using the correct permission. The correct one is:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />By the way, your demand can only be fulfilled by:
<using-permission android:name="ACCESS_FINE_LOCATION" />So there is no need for
ACCESS_COARSE_LOCATION
