Hi to all I am trying to make a pin .. The issue is I couldn't find related source with my question . I've checked commonsware topics but none of them covers a draggable pin. Actually one of them has but it is related with maps v1 not v2 .. So how can I make a pin that occurs on users current position , and then could be dragged anywhere on the map when they tap on the pin..
Here is a sample code which has a pin (marker) and finds user location ..
public class MainActivity extends AbstractMapActivity implements
OnNavigationListener, OnInfoWindowClickListener,
OnMyLocationChangeListener {
private static final String STATE_NAV="nav";

all the documentation you need is right here
https://developers.google.com/maps/documentation/android/
all you have to do is set the marker to draggable
marker.setDraggable(true);

I'm building an app, and I run on a problem with Google Maps. I wrote most of the code, but I don't how how to set that when user clicks on item(method onItemClick), in my case I have ListView on Firebase that is showing Tours of concerts, which you can see here:my tours listview to open a specific place and show it on map. For example, user clicks on Anaheim, CA concert and it shows where that place is. Thanks in advance.
public class MapActivity extends AppCompatActivity implements OnMapReadyCallback {
private static final int REQUEST_LOCATION_PERMISSION = 10;

Since you have your coordinates, you can build a LatLng(latitude, longitude) object
then you can move the camera of your map like this:
build a new camera position using CameraPosition.Builder() and then ask to your mGoogleMap to animate to that position:
CameraPosition position = CameraPosition.builder()
.target(location)
.zoom(16f)
.bearing(0.0f)
.tilt(0.0f)
.build();
mGoogleMap.animateCamera(CameraUpdateFactory.newCameraPosition(position), null)
using that position you can even put a marker on the map:
mGoogleMap.addMarker(new MarkerOptions().position(position)
.title("some title"));
I'm developing an app by using mapbox api. At the map when the user clicks map item on menu a fragment is opening.Later user may want to change mapview style such as satellite,dark,emerald or just a street view. User is able to choose map style on action bar. I implemented my action bar on main activity. When the user on map fragment choose map style and a variable comes to fragment which handled in main activity. This variable is the string of map style. Now I want to change map view style without recreating map fragment. What can you advise about this problem ?

Your map fragment should have a getMapAsync() call which you can change the style of. Heres a rough example of how you can accomplish this:
private MapboxMap map;
...
mapFragment.getMapAsync(new OnMapReadyCallback() {
#Override
public void onMapReady(final MapboxMap mapboxMap) {
map = mapboxMap;
}
});
...
// Wherever you implemented receiving the style string from MainActivity you can include this:
map.setStyleUrl(<style url>);
If this doesn't work for you, please let me know how exactly you are creating the map fragment. Currently the SDK includes a fragment already which you can setup like so:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SupportMapFragment mapFragment;
if (savedInstanceState == null) {
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
LatLng patagonia = new LatLng(-52.6885, -70.1395);
MapboxMapOptions options = new MapboxMapOptions();
options.accessToken("<your access token here>");
options.styleUrl(Style.SATELLITE);
options.camera(new CameraPosition.Builder()
.target(patagonia)
.zoom(9)
.build());
mapFragment = SupportMapFragment.newInstance(options);
transaction.add(R.id.container, mapFragment, "mapFragment");
transaction.commit();
} else {
mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentByTag("mapFragment");
}
mapFragment.getMapAsync(new OnMapReadyCallback() {
#Override
public void onMapReady(final MapboxMap mapboxMap) {
map = mapboxMap;
}
});
}
If you did it this way you can easily change the style of the map like I said above.
Hope this helps out!
i'm developing my first app and i created the following map viewer activity:
public class MapViewer extends Activity implements OnInfoWindowClickListener, ClusterManager.OnClusterClickListener<MyItem> {
private GoogleMap map;
private LatLng defaultLatLng = new LatLng(X, Y);
private int zoomLevel = 5;
private Database db = new Database(this);
private ClusterManager<MyItem> mClusterManager;
private LatLngBounds allowedBounds;
private final LatLng northeast = new LatLng(A, B);
private final LatLng southwest = new LatLng(C, D);
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mapviewer);
LatLngBounds.Builder builder = new LatLngBounds.Builder();
builder.include(northeast);
builder.include(southwest);
allowedBounds = builder.build();
try {
map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
if (map != null) {
map.setMyLocationEnabled(true);
map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
map.getUiSettings().setRotateGesturesEnabled(false);
map.moveCamera(CameraUpdateFactory.newLatLngZoom(defaultLatLng, zoomLevel));
mClusterManager = new ClusterManager<MyItem>(this, map);
mClusterManager.setRenderer(new MyClusterRenderer(this, map, mClusterManager));
mClusterManager.setOnClusterClickListener(this);
map.setOnCameraChangeListener(mClusterManager);
map.setOnMarkerClickListener(mClusterManager);
map.setInfoWindowAdapter(new ClusterInfoWindow(getLayoutInflater()));
map.setOnInfoWindowClickListener(this);
addItems();
}
} catch (NullPointerException e) {
e.printStackTrace();
}
}
}
As you can see i set a listener to map object
map.setOnCameraChangeListener(mClusterManager);
that adds or removes clusters on markers groups, according to zoom level.
Now i would add a listener that checks if user moves on map within some bounds:
map.setOnCameraChangeListener(new OnCameraChangeListener() {
#Override
public void onCameraChange(CameraPosition cameraPosition) {
checkBounds();
}
});
But it doesn't work. It works only if i remove the previous listener (mClusterManager).
So, how to make both listener working on the same map object?
Thank you in advance for your replies and sorry for my english.
As there's only a set method and no add method, you can only set one listener at a time. But you could delegate from the one listener to the other like this:
map.setOnCameraChangeListener(new OnCameraChangeListener() {
#Override
public void onCameraChange(CameraPosition cameraPosition) {
checkBounds();
mClusterManager.onCameraChange(cameraPosition);
}
});
Of course mClusterManager does not need to implement the CameraChangeListener interface any more but just needs a method public void onCameraChange(CameraPosition cameraPosition).
I had this activity:
public class MapViewer extends Activity {
private GoogleMap map;
private Database db = new Database(this);
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mapviewer);
try {
map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
if (map != null) {
map.setMyLocationEnabled(true);
map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
map.getUiSettings().setRotateGesturesEnabled(false);
this.addMerchantMarkers(new MarkerOptions());
}
} catch (NullPointerException e) {
e.printStackTrace();
}
}
public void addMerchantMarkers(MarkerOptions mo) {
SQLiteDatabase dbRead = db.getReadableDatabase();
Cursor result = dbRead.rawQuery("SELECT title, addr, lat, lon FROM users", null);
while(result.moveToNext()) {
map.addMarker(mo.position(new LatLng(result.getFloat(2), result.getFloat(3)))
.title(result.getString(0))
.snippet(result.getString(1))
);;
}
}
}
that i changed in the following way to use markers clustering:
public class MapViewer extends Activity {
private GoogleMap map;
private Database db = new Database(this);
private ClusterManager<MyItem> mClusterManager;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mapviewer);
try {
map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
if (map != null) {
map.setMyLocationEnabled(true);
map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
map.getUiSettings().setRotateGesturesEnabled(false);
setUpClusterer();
}
} catch (NullPointerException e) {
e.printStackTrace();
}
}
private void setUpClusterer() {
mClusterManager = new ClusterManager<MyItem>(this, map);
map.setOnCameraChangeListener(mClusterManager);
map.setOnMarkerClickListener(mClusterManager);
addItems();
}
private void addItems() {
SQLiteDatabase dbRead = db.getReadableDatabase();
Cursor result = dbRead.rawQuery("SELECT lat, lon, title, addr FROM users", null);
while(result.moveToNext()) {
MyItem offsetItem = new MyItem(result.getFloat(0), result.getFloat(1));
mClusterManager.addItem(offsetItem);
}
}
}
Now i don't know how to add title, snippet and icon to every marker like previous code.
Now if i click on single marker nothing happens...
How to get that?
Here you should work with ClusterManager itself.
For example, setting on cluster item click:
mClusterManager.setOnClusterItemClickListener(new ClusterManager.OnClusterItemClickListener<MyItem>() {
#Override
public boolean onClusterItemClick(MyItem item) {
//put your code here
return false;
}
});
And there are other different methods in ClusterManager class.
You'll need a less obvious code to assign info window to marker or cluster - you should use this code:
mClusterManager.getMarkerCollection().setOnInfoWindowAdapter(new MarkerInfoWindowAdapter());
mClusterManager.getClusterMarkerCollection().setOnInfoWindowAdapter(new ClusterInfoWindow());
There MarkerInfoWindowAdapter and ClusterWindowAdapter is your classes, which implements GoogleMap.InfoWindowAdapter.
With icons it's a little harder, because clustering changes icons to default. You should use method:
public void setRenderer(com.google.maps.android.clustering.view.ClusterRenderer<T> view)
You could your own renderer class and override some methods. For example, to set custom icons use such a class:
class OwnIconRendered extends DefaultClusterRenderer<MyItem> {
public OwnIconRendered(Context context, GoogleMap map,
ClusterManager<MyItem> clusterManager) {
super(context, map, clusterManager);
}
#Override
protected void onBeforeClusterItemRendered(MyItem item, MarkerOptions markerOptions) {
markerOptions.icon(item.getIcon());
markerOptions.snippet(item.getSnippet());
markerOptions.title(item.getTitle());
super.onBeforeClusterItemRendered(item, markerOptions);
}
}
And use it in such way:
mClusterManager.setRenderer(new OwnIconRendered(activity.getApplicationContext(), getMap(), mClusterManager));
I have a strange problem with a com.google.android.gms.maps.MapView.
To check if my App crashes after the garbage collector is doing his job i force my HTC One (4.2.2) to allow only 1 running app in background. If I leave my app(home button) while showing a MapView, start any other app and resume to my app, my MapView is still showing up...but I can not move or zoom the map, it's not responding at all. Other activities are working fine. I really have no clue where the problem might be.
Hope that someone can help me out?
