本文介绍了获取棉花糖中的当前位置 0，其中 23 API 以下使用融合位置给出准确的当前位置的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在 23 台以下的设备中获得了当前位置，但在 23 台模拟器设备中获得了 (0.0,0.0) 纬度和经度.
编辑目前我正在使用 Fused Location Provider 获取当前位置
EDIT Currently I am using Fused Location Provider for get Current Location
public class ContactUsFragment extends Fragment implements ConnectionCallbacks, OnConnectionFailedListener, LocationListener {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.i("TAG", "OnCreate Called");
locationManager = (LocationManager) getActivity()
.getSystemService(Context.LOCATION_SERVICE);
buildGoogleApiClient();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
final Bundle savedInstanceState) {
// Inflate the layout for this fragment
view = inflater.inflate(R.layout.fragment_contact_us, container, false);
Log.i("TAG", "OnCreateView Called");
setComponants(view); // **** Method For Set Componants Of Layout
这是点击它的地图图像我想获取当前位置并将其传递给设备的本机谷歌地图应用程序以导航到目标位置
mapImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.i("TAG", "On ImageView Click");
if (Build.VERSION.SDK_INT >= 23) {
if (checkPermission(Manifest.permission.ACCESS_FINE_LOCATION, getActivity().getApplicationContext(), getActivity())) {
if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
navigateToGoogleMap();
} else {
showSettingsAlert();
}
} else {
requestPermission(Manifest.permission.ACCESS_FINE_LOCATION, PERMISSION_REQUEST_CODE, getActivity().getApplicationContext(), getActivity());
}
} else {
if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
navigateToGoogleMap();
} else {
showSettingsAlert();
}
}
}
});
return view;
}
下面是获取当前位置的代码
private synchronized void buildGoogleApiClient() {
Log.i("TAG", "Building GoogleApiClient");
mGoogleApiClient = new GoogleApiClient.Builder(getActivity().getApplicationContext())
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
createLocationRequest();
}
private void createLocationRequest() {
mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(UPDATE_INTERVAL);
mLocationRequest.setFastestInterval(FASTEST_INTERVAL);
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
builder = new LocationSettingsRequest.Builder()
.addLocationRequest(mLocationRequest);
//**************************
builder.setAlwaysShow(true); //this is the key ingredient
//**************************
}
@Override
public void onConnected(Bundle bundle) {
Location mCurrentLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
// Note that this can be NULL if last location isn't already known.
if (mCurrentLocation != null) {
// Print current location if not null
Log.d("DEBUG", "current location: " + mCurrentLocation.toString());
currentlatitude = mCurrentLocation.getLatitude();
currentlongitude = mCurrentLocation.getLongitude();
}
// Begin polling for new location updates.
startLocationUpdates();
}
private void startLocationUpdates() {
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient,
mLocationRequest, this);
}
private void stopLocationUpdates() {
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
}
@Override
public void onConnectionSuspended(int i) {
if (i == CAUSE_SERVICE_DISCONNECTED) {
Toast.makeText(getActivity().getApplicationContext(), "Disconnected. Please re-connect.", Toast.LENGTH_SHORT).show();
} else if (i == CAUSE_NETWORK_LOST) {
Toast.makeText(getActivity().getApplicationContext(), "Network lost. Please re-connect.", Toast.LENGTH_SHORT).show();
}
mGoogleApiClient.connect();
}
@Override
public void onLocationChanged(Location location) {
String msg = "Updated Location: " +
Double.toString(location.getLatitude()) + "," +
Double.toString(location.getLongitude());
Toast.makeText(getActivity().getApplicationContext(), msg, Toast.LENGTH_SHORT).show();
currentlatitude = location.getLatitude();
currentlongitude = location.getLongitude();
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
}
*当我在以下 API23 设备中使用时，此代码工作正常，但当我尝试在棉花糖设备上时，它给出当前位置 0.0,0.0 *
*This code is Working Properly when I use in below API23 devices but when I try on marshmallow Device it give current Location 0.0,0.0 *
