I am building an android application where user is getting latLng by long touching in Google map.
Here is the code:
public class MainActivitytut extends FragmentActivity{
GoogleMap googleMap;
MarkerOptions markerOptions;
LatLng latLng;
private TextView myAddress;
String lat;
TextView txtmapinfo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maintut);
//onBackPressed();
SupportMapFragment supportMapFragment = (SupportMapFragment)
getSupportFragmentManager().findFragmentById(R.id.map);
// Getting a reference to the map
googleMap = supportMapFragment.getMap();
// Setting a click event handler for the map
googleMap.setOnMapClickListener(new OnMapClickListener() {
#Override
public void onMapClick(LatLng arg0) {
// Getting the Latitude and Longitude of the touched location
latLng = arg0;
lat = latLng.toString();
// Toast.makeText(getApplicationContext(), lat,
// Toast.LENGTH_LONG).show();
// getMyLocationAddress();
// Clears the previously touched position
googleMap.clear();
// Animating to the touched position
googleMap.animateCamera(CameraUpdateFactory.newLatLng(latLng));
// Creating a marker
markerOptions = new MarkerOptions();
// Setting the position for the marker
markerOptions.position(latLng);
// Placing a marker on the touched position
googleMap.addMarker(markerOptions);
// Adding Marker on the touched location with address
new ReverseGeocodingTask(getBaseContext()).execute(latLng);
}
});
}
protected void putExtra(String string, CharSequence text) {
// TODO Auto-generated method stub
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is
// present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
I had used lat = map.getCameraPosition().target; and when I toast the value of lat, it is toasting 0.0
What I need is that when on swiping the map the latlng change and toast.
Wait until the map has loaded and then call getCameraPosition:
mMap.setOnMapLoadedCallback(new GoogleMap.OnMapLoadedCallback() {
#Override
public void onMapLoaded() {
LatLng pos = mMap.getCameraPosition().target;
Log.e("", "Pos: " + pos.toString());
mMap.addMarker(new MarkerOptions().position(pos));
}
});

I am creating an app which displays several pins which have different categories according to colour, similar to displaying hotels, restaurants etc. I have a menu which when I select the option I want to hide that particular category but I am having trouble hiding the pins, I'm just not sure what code to use for this.
I've tried to use setVisibility(invisible) but I don't know where this should go.
This is within my main activity - the menu.
public class AR_MapsActivity extends AppCompatActivity implements OnMapReadyCallback {
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.menu.main_menu, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
//trying to get the menu options to do something
switch(item.getItemId()){
case R.id.poi1:
Toast.makeText(this, "Enemy Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.poi2:
Toast.makeText(this, "IED Selected", Toast.LENGTH_SHORT).show();
return true;
case R.id.poi3:
Toast.makeText(this, "Obstruction Selected", Toast.LENGTH_SHORT).show();
return true;
default:
return super.onOptionsItemSelected(item);
}
This is where the map pins are created, also within main activity.
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
mMap.setMyLocationEnabled(true);
LocationManager and listener
locationManager = (LocationManager)this.getSystemService(Context.LOCATION_SERVICE);
locationListener = new LocationListener() {
#Override
public void onLocationChanged(Location location) {
mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
// Add a marker in Sydney and move the camera
LatLng userLocation = new LatLng(location.getLatitude(), location.getLongitude());
mMap.clear();
mMap.addMarker(new MarkerOptions().position(userLocation).title("AR Projects HQ")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(userLocation, 16));
LatLng obstruction = new LatLng(50.878640, -2.108940);
mMap.addMarker(new MarkerOptions().position(obstruction).title("Obstruction").snippet("Fallen Power Lines. Eng notified.")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_ORANGE)));
The program runs no problem and displays a toast to display which option has been selected.
set varible to mMap.addMarker
Marker mark = mMap.addMarker(new MarkerOptions() ....
mark.setVisible(false);
this Marker can add to array if you want
List<Marker> markList = new ArrayList<>();
////
Marker mark = mMap.addMarker(new MarkerOptions() ....
markList.add(mark);
//// and then you can hide with loop
for (Marker miaw : markList) {
miaw.setVisible(false);
}
I started working on an old application i have that uses a map fragment on a navigation drawer. It used to work OK but now, with the new permisson thing, I get some errors. I have searched on SO and on the internet generally but I dont know what I am missing. My map Fragment is below

I used googleMap = mMapView.getMap(); to get the map but i have change it with mMapView.getMapAsync(this); by implementing OnMapReadyCallback and it forced me to create the onMapReady method, which I dont know how it is different from the onCreateView method so i leave it empty.
Now i get an error on googleMap.setMyLocationEnabled(true); for permission and when i debug my app the googleMap object is null.
When I run it, on selecting the map fragment the app crashes and terminates the activity that holds the Fragments.
On the Manifest i have
android:minSdkVersion="17"
android:targetSdkVersion="23"
and my gradle dependencies are
compile 'com.android.support:support-v4:24.2.1'
compile 'com.android.support:appcompat-v7:24.2.1'
compile 'com.google.android.gms:play-services:+'
What am i missing here? How can i use the permission in the fragment and why googleMap is empty?
Move this code from your onCreateView to your onMapReady:
// Detect location
googleMap.setMyLocationEnabled(true);
googleMap.getUiSettings().setMyLocationButtonEnabled(false);
//googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
// Turns traffic layer on
googleMap.setTrafficEnabled(true);
// Enables indoor maps
googleMap.setIndoorEnabled(true);
// Enables indoor maps
googleMap.setIndoorEnabled(true);
// Turns on 3D buildings
googleMap.setBuildingsEnabled(true);
// Show Zoom buttons
googleMap.getUiSettings().setZoomControlsEnabled(true);
// latitude and longitude
double latitude = 40.639350;
double longitude = 22.944607;
googleMap.setOnMapLongClickListener(this);
googleMap.setOnMapClickListener(this);
// create marker
MarkerOptions thessaloniki = new MarkerOptions().position(new LatLng(latitude, longitude)).title("Thessaloniki");
// Changing marker icon
thessaloniki.icon(BitmapDescriptorFactory .defaultMarker(BitmapDescriptorFactory.HUE_ROSE));
// adding marker
googleMap.addMarker(thessaloniki);
CameraPosition cameraPositionThess = new CameraPosition.Builder() .target(new LatLng(40.639350, 22.944607)).zoom(12).build();
googleMap.animateCamera(CameraUpdateFactory .newCameraPosition(cameraPositionThess));
The line mMapView.getMapAsync(this); prepares the map and onMapReady gets called when the map is ready to be used.
Also, if you have defined private GoogleMap googleMap;, you will want to add this to the beginning of your onMapReady method:
this.googleMap = googleMap;
I followed this tutorial to add a map to one of my tabs. It works, but when I open the map tab I cannot swipe up/down, zoom in/out (except when I double click). Swiping left/right works, but the map moves very little. I made a customViewPager, and it disables swiping the tabs, but does nothing for he map.
At first I used tabActivity and my map fragment worked as it should, and looked like this:
mapActivity extends FragmentActivity...
Since tabActivity is deprecated I added sliding tabs, following the tutorial above. Map could not be added with FragmentActivity, only with Fragment so I changed map fragment to:
mapActivity extends Fragment...
Now I have the following problem - I cannot navigate the map. Swipe and touch inputs are not detected. I cannot move up or down, zoom in or out, and the only thing I can do is move from left to right, but it is very slow.
Try this. its sample . 100% working

At first I added tabLayout and viewPager to appBarLayout in app_bar_main (I made an app with navigation drawer), and later I moved the appBarLayout to content_main and it worked.
I want to pin a new mark on my map but method onMapLongClick didn work.
My code is below. I have my map inside a fragment.

As you can see I have both onMapClick and onMapLongClick methods but when I click on map nothing happens. I also have implement OnMapLongClickListener and OnMapClickListener. What am I doing wrong?
Thanks in advance.
Your class implements the listener but you don't set it:
googleMap.setOnMapLongClickListener(this);
same with the normal click listener:
googleMap.setOnMapClickListener(this);
below is my code which display map of all world i want when application start is show specific city not world map i follow this tutorial http://android-er.blogspot.com/2013/01/google-maps-android-api-v2-example-draw.html every thing work fine but i want when app start first time is display specific city map not all global map i dont want show globap map like this image http://1.bp.blogspot.com/-dwjqTWCdONg/UObUk1syAFI/AAAAAAAAGy8/S43YMKuXZRc/s1600/screen_MapsAPIv2_Polygon.png on app start i want specific city map like newyork for example.

add this code to your onCreate:
#Override
protected void onCreate(Bundle savedInstanceState) {
.
.
.
// define point to center on
LatLng origin = new LatLng(40.67, -73.94);
CameraUpdate panToOrigin = CameraUpdateFactory.newLatLng(origin);
myMap.moveCamera(panToOrigin);
// set zoom level with animation
myMap.animateCamera(CameraUpdateFactory.zoomTo(14), 400, null);
}
After the onClikListener are setted (into onCreate), put this code
LatLng NewYork= new LatLng(40.714623,-74.006605);
CameraPosition camPos = new CameraPosition.Builder().target(NewYork).zoom(14).build();
CameraUpdate cam = CameraUpdateFactory.newCameraPosition(camPos);
myMap.animateCamera(cam);
It will animate your map and move the camera to NY
