所以這就是我如何獲得用戶當前位置用於我的谷歌地圖。
if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED || ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
mMap.setMyLocationEnabled(true);
Criteria criteria = new Criteria();
LocationManager locationManager = (LocationManager)getActivity().getSystemService(Context.LOCATION_SERVICE);
String provider = locationManager.getBestProvider(criteria, false);
Location location = locationManager.getLastKnownLocation(provider);
double lat = location.getLatitude();
double lng = location.getLongitude();
LatLng coordinate = new LatLng(lat, lng);
CameraUpdate yourLocation = CameraUpdateFactory.newLatLngZoom(coordinate, 13);
mMap.animateCamera(yourLocation);
} else {
final AlertDialog alertDialogGPS = new AlertDialog.Builder(getActivity()).create();
alertDialogGPS.setTitle("Info");
alertDialogGPS.setMessage("Looks like you have not given GPS permissions. Please give GPS permissions and return back to the app.");
alertDialogGPS.setIcon(android.R.drawable.ic_dialog_alert);
alertDialogGPS.setButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Intent intentSettings = new Intent(Settings.ACTION_APPLICATION_SETTINGS);
startActivity(intentSettings);
alertDialogGPS.dismiss();
}
});
alertDialogGPS.show();
}
謝謝您的建議。我想通過你的解決方案。但是我覺得它不會提供那麼大的靈活性。我的意思是我提到那些照顧位置提供者的API。這意味着如果GPS不可用,那麼它會自動使用其他提供商的位置。所以我會錯過這些功能。當然,我會嘗試你的解決方案。 – nilkash
