我正在创建一个应用程序,我必须获取用户的经度和纬度并标记其位置。我的应用程序发出错误“不幸地图已停止”。我google了很多但无法找到解决方案。这是我的代码和我的日志猫。
public class MapView extends Activity {
private LocationManager locationManager;
private String best;
double myLocationLatitude;
double myLocationLongitude;
Location loc = locationManager.getLastKnownLocation(best);
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map_layout);
locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
// additionally (you have to implement LocationListener)
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0.0f, new android.location.LocationListener()
{
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
Log.d("a","onLocationChanged: lat=" +location.getLatitude());
Log.d("a","onLocationChanged: lat=" +location.getLongitude());
}
});
locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
GoogleMap mMap = null;
mMap.addMarker(new MarkerOptions().draggable(true)
.position(new LatLng(loc.getLatitude(),loc.getLongitude()))
.title("YOUR LOCATION"));

您是否已将活动添加到Android清单中?
如果我忘记将其添加到清单中,我也会收到此错误。

您还需要授权您的应用访问GPS。
只需放行
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
进入你的清单,一切都会好起来的。
