I'm using google map in my application ,when I click the marker info-window is opened again I want to click the info-window layout but its not working for layouts.If I give click listener for button means its working.Please help me to fix this issue.

I implement google map view inside fragment, everything is working but Marker is not moving into new location its fixed. I tried long press,listeners,tapping on other part of map, Nothing works.
MapView Fragment
public class MapLocation_Fragment extends Fragment implements GoogleMap.OnMarkerDragListener,GoogleMap.OnMarkerClickListener,OnMapReadyCallback {
MapView mapView;

mapView.onCreate(savedInstanceState);
mapView.onResume();// Needed tog et the map to display immediately
lati=getArguments().getDouble("lat");

I need to marker to move where ever user tap on map but after lot of effort its still not moving at all. Please help guys.
To make your marker move when dragging it you need to write some code in your onMarkerDragEnd method, basically to update the position of your marker (locclPosition) to where the dragging ends (new coordinates)
#Override
public void onMarkerDragEnd(Marker marker) {
locclPosition = marker.getPosition();
}
I have a problem with pressing an option in my navigationView (R.id.create_marker) I want to create a marker in my MapFragment, but I can not do it, any suggestions?
Code of MainActivity.java where I press the menu option:
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.create_marker:
Toast.makeText(MainActivity.this, "Crear Marker", Toast.LENGTH_SHORT).show();
// Create marker and display it on the map
break;
}
return false;
}
});
Code of MapFragment.java:
public class MapFragment extends Fragment
implements OnMapReadyCallback {
private View rootView;
private GoogleMap gMap;
private MapView mapView;
public MapFragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.fragment_map, container, false);
return rootView;
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
mapView = (MapView) rootView.findViewById(R.id.map);
if (mapView != null) {
mapView.onCreate(null);
mapView.onResume();
mapView.getMapAsync(this);
}
}
#Override
public void onResume() {
super.onResume();
}
#Override
public void onMapReady(GoogleMap googleMap) {
}
}
This is the structure of my project:
To create a marker, you need to call addMarker method on your Map, once it's ready to be used.
public void onMapReady(GoogleMap googleMap) {
// Add a marker in Sydney, Australia,
// and move the map's camera to the same location.
LatLng sydney = new LatLng(-33.852, 151.211);
googleMap.addMarker(new MarkerOptions().position(sydney)
.title("Marker in Sydney"));
googleMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}
If you want your Map to open a marker for a fixed Lat-Lng, pass in the coordinates as shown in the code above, otherwise request location via Google Location Api and pass the obtained Lat-Lng values to the addMarker() method.
I've a class "MainActivity" which calls the different fragments in particular a fragment which display a GoogleMap called MapsFragment.
When this fragment is called for the first time, I had some markers (which are refresh every timeToRefresh. The method startDrawingBomb() is called from the MainActivity class) and everything works perfectly when the user do not change to another fragment.
When a user ask to move to an other fragment I save the the MapsFragment created before in the backStack of the MainActivity (to retrieve it later)
The problem happens when I call this MapsFragment a second time, the fragment is displaying the map but not all the markers I've added before.
I imagine it's because the MapView, and the GoogleMap created by the MapsFragment are not the same as before.
My question is : How can I retrieve the map that I draw before easily ? Or I had to stop all my threads (in onPause() for example), create a new MapsFragment, obtain a new MapView, a new GoogleMap object and apply again all the previous threads ?
This is a part of my MapsFragment :
public class MapsFragment extends Fragment implements OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks,GoogleApiClient.OnConnectionFailedListener, LocationListener {

fragmentManager.beginTransaction().replace(R.id.frame_container, fragment,MAPS_FRAGMENT).addToBackStack(MAPS_FRAGMENT).commit();
}
}
Thanks a lot everyone, and sorry for my bad English.
If you want more information, or a better explanation, don't hesitate to tell me !
Implement save to bundle functionality at Onpause() for your MapFragment. Then in onCreateView() always check your bundle.
If the bundle is empty then it's a new fragment. If the bundle is not empty this means it was previously created.
Hope this helps :
For saving and restoring to bundle : Saving Android Activity state using Save Instance State
I have main activity with fragments and one of the fragments is Map Fragment. Now, when i tap there, every time it opens slow. I am using singleton instance of fragment, but it still doesnt work as expected. Here is a good of that class:

You can try to add markers only if it would be visible? I mean: first move camera to start position and set zoomLevel and just after that add Markers but only if it's in visible sector. And update markers on camera move.
Title can be a bit complicated but the problem is literally as described. I'm trying to use google map fragment within a fragment stack. When the application starts the user will see a button and when the user pushes the button, current view will be replaced with map fragment. Currently, I'm able to replace the fragments but when the map fragment is shown, the view still has the button of previous fragment.Also I'm trying to replace fragments in one of the tabs of my app. Here is my code;
Map Fragment;
public class MapFragment extends Fragment {
MapView mMapView;
private GoogleMap googleMap;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.activity_maps, container, false);
mMapView = (MapView) rootView.findViewById(R.id.mapView);
mMapView.onCreate(savedInstanceState);
mMapView.onResume(); // needed to get the map to display immediately
try {
MapsInitializer.initialize(getActivity().getApplicationContext());
} catch (Exception e) {
e.printStackTrace();
}
mMapView.getMapAsync(new OnMapReadyCallback() {
#Override
public void onMapReady(GoogleMap mMap) {
googleMap = mMap;
try {
googleMap.setMyLocationEnabled(true);
} catch (SecurityException e) {
e.printStackTrace();
}
// For dropping a marker at a point on the Map
LatLng sydney = new LatLng(-34, 151);
googleMap.addMarker(new MarkerOptions().position(sydney).title("Marker Title").snippet("Marker Description"));
// For zooming automatically to the location of the marker
CameraPosition cameraPosition = new CameraPosition.Builder().target(sydney).zoom(12).build();
googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
}
});
return rootView;
}

Often you will want one Fragment to communicate with another, for
example to change the content based on a user event. All
Fragment-to-Fragment communication is done through the associated
Activity. Two Fragments should never communicate directly.
Your fragments shouldn't communicate directly according to the documentation.
If you've managed to communicate with your fragments considering the documentation. Then you can use this simple method to be able to change and reuse any fragment.
In your host activity :
private void changeFragment(Fragment frag, boolean saveInBackstack) {
String backStateName = ((Object) frag).getClass().getName();
try {
FragmentManager manager = getSupportFragmentManager();
if (manager.findFragmentByTag(backStateName) == null) {
//fragment not in back stack, create it.
FragmentTransaction transaction = manager.beginTransaction();
transaction.replace(R.id.container, frag, backStateName);
if (saveInBackstack) {
Log.d(TAG, "Change Fragment: addToBackTack " + backStateName);
transaction.addToBackStack(backStateName);
} else {
Log.d(TAG, "Change Fragment: NO addToBackTack");
}
transaction.commit();
} else {
manager.popBackStack();
}
} catch (IllegalStateException exception) {
Log.w(TAG, "Unable to commit fragment, could be activity as been killed in
}
}
just add android:background="#android:color/white" on the main view of the map_layout xml file
Here is the solution;
Home Fragment;
public class HomeFragment extends RootFragment {
private LocationManager locationManager;
public HomeFragment() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Obtain the shared Tracker instance.
locationManager = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.home_tab, container, false);
Button go = (Button) v.findViewById(R.id.btn_go);
go.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(getActivity(), MapFragment.class);
if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
//Toast.makeText(getContext(), "GPS is Enabled in your devide", Toast.LENGTH_SHORT).show();
startActivity(intent);
}
}
});
return v;
}
