我正在尝试获取
android的经度和纬度,这是我的代码：
LocationManager locationManager = (LocationManager)
this_activity.getSystemService(Context.LOCATION_SERVICE);
LocationListener locationListener = new MyLocationListener();
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,5000,10,locationListener);
public class MyLocationListener implements LocationListener {
@Override
public void onLocationChanged(Location loc) {
longitude = Double.toString(loc.getLongitude());
latitude = Double.toString(loc.getLatitude());
}
@Override
public void onProviderdisabled(String provider) {}
@Override
public void onProviderEnabled(String provider) {}
@Override
public void onStatusChanged(String provider,int status,Bundle extras) {}
}
清单Permissions：
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
经度和纬度我总是得到0.0秒
解决方法
除了@AshishPedhadiya提到你只听GPS提供商的权限.
LocationListener locationListener = new MyLocationListener();
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,locationListener);
GPS无法在里面工作.因此,当您测试应用程序时,它几乎总是会返回(0,0)位置.您可能也想收听NETWORK_PROVIDER,如果没有GPS位置,它会估计来自手机信号塔和WiFi点的位置.
locationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER,locationListener);
此外,要获取快速地理位置,请查看Application.getLastKNownLocation()方法.
