Hi i have question how to implement info window on click on marker?
the problem is i have many marker on map and each marker have another activity if info window is clicked.enter code here
heres the example
Marker One-----> if clicked infowindow marker one then ActivityOne will show up
Marker Two-----> if clicked infowindow marker two then ActivityTwo will show up
i have tried many code but not solved
Intent intent = new Intent(ThisActivity.this,OneActivity.class);
startActivity(intent);
}
});
This is perfectly working:
mapview.setOnInfoWindowClickListener(new OnInfoWindowClickListener() {
#Override
public void onInfoWindowClick(Marker marker) {
if(marker==marler1){
Intent intent = new Intent(MapActivity.this,Activity1.class);
startActivity(intent);
}else(marker==marler2){
Intent intent = new Intent(MapActivity.this,Activity2.class);
startActivity(intent);
}
}
});
First: Try to search more for a solution.
Hint: (pseudo code)
Marker m1 = map.addMarker(bla bla);
Marker m2 = map.addMarker(bla bla);
onMarkerClicked(Marker m) {
if(m == m1) {
//do what you want to do for marker one
}
else if(m == m2) {
//do what you want to do for marker two
}
}
Good idea is setting marker title, and then in listener based on title do actions
marker.getTitle()
Here is my code.
first add dependency in build.gradle.
compile 'com.google.android.gms:play-services:8.4.0'
compile 'com.google.android.gms:play-services-location:8.1.0'
compile 'com.google.android.gms:play-services-maps:8.4.0'

I am using fused location provider for fetching current location and update my marker to my current location via that. I am giving app permission and then it does nothing after that. Though i have written code for that to fetch and update location on map. I have previously given Access_COARSE_LOCATION as well, but nothing changes. this is my code :-
public class MainActivity extends AppCompatActivity implements OnMapReadyCallback {
private GoogleMap mMap;

SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()

if (mapFragment != null) {
mapFragment.getMapAsync(this);
}
}

Okay so my problem was i was getting not calling getMapAsync after i allow location permission, which was making my Google Map Object null and so that was not ablw to move my camera to my current location. I have updated my code and now it works fine.

This is my code to automatically zoom on the current device's location when the activity is started and also i want the code to display the latitude and longitude of my current location.

The map appears but is at 0,0 and is not zooming on my current location and neither displaying the longitude and latitude! someone please help
i want to display current location on map, my map is in fragment and i'm using fused location provider in non activity class, but i'm not getting current location when the map is loaded, it is giving me current location only if i press mylocation button, but i want that when map is loaded it should show my current location not the world map.

I want to make move of the marker in GOOGLE MAP while gps location changes just like in UBER app. I have found some solutions but unable to solve my issue. The solutions are 1 and 2
Below is my onLocationChange() method

double lattitude = location.getLatitude();
double longitude = location.getLongitude();
mLastLocation = location;
if (mCurrLocationMarker != null) {
mCurrLocationMarker.remove();

//Place current location marker
LatLng latLng = new LatLng(lattitude, longitude);
MarkerOptions markerOptions = new MarkerOptions();
markerOptions.position(latLng);

Update 1 (Re-edited)
For more understanding i am adding some more code, but first i want to tell that i am using tabs in my app. The very first tab is of my map. So i am using fragments for it.
public class MyLocation extends Fragment implements OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener,
LocationListener{
GoogleMap mGoogleMap;
SupportMapFragment mapFrag;
LocationRequest mLocationRequest;
GoogleApiClient mGoogleApiClient;

if(view != null)
{

if(viewGroupParent !=null)
{
viewGroupParent.removeView(viewGroupParent);
}
}
try{
view = inflater.inflate(R.layout.my_location,container, false);
}catch (Exception e)
{
/* map is already there, just return view as it is */
return view;
}
// inflat and return the layout
//View rootView = inflater.inflate(R.layout.my_location, container, false);
tv_loc = (TextView)view.findViewById(R.id.textView);

Any help would be highly appreciated
You can use below code to update position of the Marker
public void onLocationChanged(Location location) {
double lattitude = location.getLatitude();
double longitude = location.getLongitude();
//Place current location marker
LatLng latLng = new LatLng(lattitude, longitude);
if(mCurrLocationMarker!=null){
mCurrLocationMarker.setPosition(latLng);
}else{
mCurrLocationMarker = mGoogleMap.addMarker(new MarkerOptions()
.position(latLng)
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED))
.title("I am here");
}
tv_loc.append("Lattitude: " + lattitude + " Longitude: " + longitude);
gMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng, 15));
//stop location updates
if (mGoogleApiClient != null) {
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
}
}
You don't need to clear map every time. You can do it by Marker object that is returned when adding Marker to Map.
Hope it will help you.
First of All implement LocationListener in your Activity then
if you need to show only one Marker(update position of Marker), use this :
private Marker currentPositionMarker = null;
#Override
public void onLocationChanged(Location location) {
LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(latLng).zoom(14).build();
// mMap.clear(); // Call if You need To Clear Map
if (currentPositionMarker == null)
currentPositionMarker = mMap.addMarker(new MarkerOptions()
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_YELLOW))
.position(latLng)
.zIndex(20));
else
currentPositionMarker.setPosition(latLng);
mMap.animateCamera(CameraUpdateFactory
.newCameraPosition(cameraPosition));
}
or if you want to add a new marker every time :
#Override
public void onLocationChanged(Location location) {
LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(latLng).zoom(14).build();
mMap.addMarker(new MarkerOptions()
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_YELLOW))
.position(latLng)
.zIndex(20));
mMap.animateCamera(CameraUpdateFactory
.newCameraPosition(cameraPosition));
}
if location was changed rapidly, it would take a couple of seconds for your app to update its location marker
This can be done using CameraPosition, googleMap.animateCamera and marker movement animation using linear interpolator.
You can take a look at this tutorial here and the respective github page.
This tutorial uses google maps v2. Hope this helps.
Use this:
implement LocationListener ,GoogleMap.OnMyLocationChangeListener in your map activity and then use location change Listener
#Override
public void onMyLocationChange(Location location) {
//mMap.clear //if you want refresh map remove comment
// Getting latitude of the current location
double latitude = location.getLatitude();
// Getting longitude of the current location
double longitude =location.getLongitude();
// Creating a LatLng object for the current location
LatLng latLng = new LatLng(latitude, longitude); //your_text_view.settext(latitude+","+longtitudde)
// Showing the current location in Google Map
mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
mMap.addMarker(new MarkerOptions().icon(BitmapDescriptorFactory.fromResource(R.drawable.destination_marker)).position(latLng).title(maping_status));
// Zoom in the Google Map
mMap.animateCamera(CameraUpdateFactory.zoomTo(20));
}
Inorder to animate just call this method (animateMarker) with previous location and new location along with Marker object
private Marker mCurrentMarker;
private float ZOOMLEVEL=18.0f;
private LatLng previousLatLon;
private Handler mLocalHandler;
private GoogleMap mGoogleMap;
public void animateMarker(final Marker marker, final LatLng toPosition,final LatLng fromPosition) {
final long duration = 500;
final Interpolator interpolator = new LinearInterpolator();
mLocalHandler.post(new Runnable() {
#Override
public void run() {
long elapsed = SystemClock.uptimeMillis() - mStartTime;
float t = interpolator.getInterpolation((float) elapsed
/ duration);
marker.setPosition(toPosition);
marker.setAnchor(Constants.MAPANCHOR, Constants.MAPANCHOR);
mGoogleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(toPosition, ZOOMLEVEL));
if (t < 1.0) {
// Post again 16ms later.
mLocalHandler.postDelayed(this, 16);
} else {
marker.setVisible(true);
}
}
}
});
previousLatLon=toPosition;// reassign the previous location to current location
}

If you're still looking for the solution, hope this https://www.youtube.com/watch?v=WKfZsCKSXVQ will help you. I've used this in one of my apps and it helps animating the marker from one location to other location.
Source code can be grabbed here https://gist.github.com/broady/6314689.
You might need to add rotation to your marker to show the exact direction of the marker. Following is the block of code that I'm using to find bearing.
private float bearingBetweenLatLngs(LatLng begin, LatLng end) {
Location beginL = convertLatLngToLocation(begin);
Location endL = convertLatLngToLocation(end);
return beginL.bearingTo(endL);
}

Your onMapReady(GoogleMap googleMap) is not being called.
You need to call getMapAsync on the map fragment to set the OnMapReadyCallback
From the documentation
public void getMapAsync (OnMapReadyCallback callback)
Sets a callback object which will be triggered when the GoogleMap
instance is ready to be used.
Add this code at the end of your onCreate function:
MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
Use the Marker Class
An icon placed at a particular point on the map's surface. A marker icon is drawn oriented against the device's screen rather than the map's surface; i.e., it will not necessarily change orientation due to map rotations, tilting, or zooming.
A marker has the following properties:
Anchor
The point on the image that will be placed at the LatLng position of the marker. This defaults to 50% from the left of the image and at the bottom of the image.
Position
The LatLng value for the marker's position on the map. You can change this value at any time if you want to move the marker.
Title
A text string that's displayed in an info window when the user taps the marker. You can change this value at any time.
Snippet
Additional text that's displayed below the title. You can change this value at any time.
Icon
A bitmap that's displayed for the marker. If the icon is left unset, a default icon is displayed. You can specify an alternative coloring of the default icon using defaultMarker(float). You can't change the icon once you've created the marker.
Drag Status
If you want to allow the user to drag the marker, set this property to true. You can change this value at any time. The default is true.
Visibility
By default, the marker is visible. To make the marker invisible, set this property to false. You can change this value at any time.
