Troubles with reading from Firebase database Android - android

UPD: I've found that there is something bad is happening to latitude and longitude field when I'm getting it from the database, for example it does not shows correctly using Toast.
I'm using a Firebase database in my project. It saves locations with additional information to Firebase database and I need to display markers corresponding to that locations on the map.
The writing database works without perfect.
However, reading does not work at all. I've followed this guide and defined the database as a field on my class, added instantiation in onCreate method and added ValueListener.
DatabaseReference databaseEvents;
//some code
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
databaseEvents = FirebaseDatabase.getInstance().getReference("events");
}
//somecode
databaseEvents.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
// events.clear();
Toast.makeText(MapsActivity.this, "LUL", Toast.LENGTH_SHORT).show();
for (DataSnapshot event : dataSnapshot.getChildren()) {
Event e = event.getValue(Event.class);
events.add(e);
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
//here I'm trying to display the markers.
When I'm trying to output the size of events it always prints 0 and so it does not print any marker on the map.
The full code is here:

How to get the current data of the marker that is in array list?

I am currently working with the google map. I already show the markers and the title and snippet of the marker.
Now my problem is when I click the info window it will be redirected to a new activity and get the data of the marker that was clicked. Here is my code:

google marker open activity when marker is clicked

I have created an app that shows the list of bar locations by a marker on a map taken from a database on firebase.
each bar has a list of beverages.
what I wish to happen is that when a marker is clicked a new activity will open with the name of the bar selected at the top of the new activity
What i wish to happen is that when the marker is clicked it will open a new activity
//Declaration list of venues
List<Venue> venueList;
//onCreate method
venueList = new ArrayList<>();
mVenues.push().setValue(marker);
//onMapsReady method, gets the venues into the map
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
mVenues.addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
for (DataSnapshot s : dataSnapshot.getChildren()){
Venue venue = s.getValue(Venue.class);
venueList.add(venue);
for (int i = 0; i < venueList.size(); i++)
{
LatLng latLng = new LatLng(venue.venueLat,venue.venueLong);
if (mMap != null) {
marker = mMap.addMarker(new MarkerOptions()
.position(latLng).title(venue.venueName));
}
}
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
//Marker Click Event
//CMarker click event to take user to purchase beverage
mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener(){
public boolean onMarkerClick(Marker marker) {
String title = marker.getTitle();
{
for (int i = 0; i < venueList.size();) {
//getting the selected venue
Venue venue = venueList.get(i);
//creating an intent
Intent intent = new Intent(getApplicationContext(), viewbeverageActivity.class);
//putting venue name and id to intent
intent.putExtra(VENUE_ID, venue.getVenueId());
intent.putExtra(VENUE_NAME, venue.getVenueName());
//starting the activity with intent
startActivity(intent);
}
return false;
}
}
});
//Venue Class
package uk.ac.ferry_j2ulster.beerapp;
import com.google.firebase.database.IgnoreExtraProperties;
public class Venue {
private String venueId;
public String venueName;
private String venueType;
public double venueLat;
public double venueLong;
public Venue(){
}
public Venue(String venueId, String venueName, String venueType,double venueLat, double venueLong) {
this.venueId = venueId;
this.venueName = venueName;
this.venueType = venueType;
this.venueLat = venueLat;
this.venueLong = venueLong;
}
public String getVenueId() {
return venueId;
}
public String getVenueName() {
return venueName;
}
public String getVenueType() {
return venueType;
}
public double getVenueLong() { return venueLong;
}
public double getVenueLat() {return venueLat;
}
}
I hope to open a new activity with the bar that was selected as a title at the top
no errors, not sure how to start with this one

The problem is that you are using a loop to go through each Venue, and calling startActivity() for all venues.
Instead, define a HashMap that will map each Marker ID to a Venue ID:
Map<String, String> mMarkerMap = new HashMap<>();
Then, put an entry in the HashMap for each Marker:
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
for (DataSnapshot s : dataSnapshot.getChildren()){
Venue venue = s.getValue(Venue.class);
venueList.add(venue);
for (int i = 0; i < venueList.size(); i++)
{
LatLng latLng = new LatLng(venue.venueLat,venue.venueLong);
if (mMap != null) {
marker = mMap.addMarker(new MarkerOptions()
.position(latLng).title(venue.venueName));
//Added:
mMarkerMap.put(marker.getId(), venue.getVenueId());
}
}
}
}
Then, when the user taps a Marker, get the title and Venue ID from the Marker/HashMap, and send it to the new activity:
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
//...........
mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
#Override
public boolean onMarkerClick(Marker marker) {
String venueID = mMarkerMap.get(marker.getId());
String venueName = marker.getTitle();
Intent intent = new Intent(MapActivity.this, NewActivity.class);
intent.putExtra(VENUE_NAME, venueName);
intent.putExtra(VENUE_ID, venueID);
startActivity(intent);
return false;
}
});
}
In the new activity, simply get the title and Venue ID Strings passed in:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new);
String venueName = getIntent().getStringExtra(MapActivity.VENUE_NAME);
if (title != null) {
getSupportActionBar().setTitle(title);
}
String venueID = getIntent().getStringExtra(MapActivity.VENUE_ID);
if (venueID != null) {
//use venue ID to get the information about this venue
}
//.......
}

You need to pass venue information also to the activity :
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
//...........
mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
#Override
public boolean onMarkerClick(Marker marker) {
String title = marker.getTitle();
Venue venue = NULL;
for(int i=0;i<venueList.size();i++)
{
if(venueList.get(i).getTitle().equal(title))
venue = venueList.get(i);
}
Intent intent = new Intent(MapActivity.this, NewActivity.class);
intent.putExtra("title", title);
intent.putExtra("venue",venue.toJSON());
startActivity(intent);
return false;
}
});
}
Make a toJSON() function in your venue class and also fromJSON() which will help you in sending venue data as well.

Your handling of the Google Map inside your onCreate() method seems slightly different than what I have used and seen. Try using this code instead:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.maps);
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this); // don't pass Maps.this
// rest of your code here
}
My hunch is that somehow you were binding the listener twice, though I can't prove this without trying to duplicate your actual code locally.

You should do second query only after will get result of first one, because g is null until will be initialized by callback.
Update:
public class Map_Masti extends FragmentActivity {
ParseGeoPoint g;
private SupportMapFragment mapFragment;
private TextView textView;
private void getG() {
ParseQuery<ParseUser> query = ParseUser.getQuery();
query.getInBackground("ccm3xKMmr4", new GetCallback<ParseUser>() {
public void done(ParseUser object, ParseException e) {
if (e == null) {
g = (ParseGeoPoint) object.get("user_Location");
Log.d("mohit", g + "");
getLocations();
} else {
// something went wrong
Log.d("mohit", e + " ");
}
}
});
}
private void getLocations() {
ParseQuery<Rahees> mapQuery1 = Rahees.getQuery();
mapQuery1.whereWithinKilometers("Locations", g, 6000);
mapQuery1.setLimit(3);
mapQuery1.findInBackground(new FindCallback<Rahees>() {
#Override
public void done(List<Rahees> objects, ParseException e) {
// Handle the results
if (e == null) {//****this is where the exception error comes, it doesn't goes inside if statement****
for (int i = 0; i < objects.size(); i++) {
Log.d("mohit", "2" + objects.get(i).get("Locations"));

Android get the current location as start point in Google Maps Android API V2

I am trying to create route from current location to the direction, now i can use fixed latitude and longitude, but how to use my current location.
this is my file:
public class DirectionActivity3 extends FragmentActivity {
TextView textProgress;
Button buttonAnimate, buttonRequest;
double mLatitude=0;
double mLongitude=0;
GoogleMap mMap;
GoogleDirection gd;
Document mDoc;
LatLng start = new LatLng(mLatitude,mLongitude);
LatLng end = new LatLng(3.158847, 101.713837);
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_direction_1);
mMap = ((SupportMapFragment)getSupportFragmentManager()
.findFragmentById(R.id.map)).getMap();
mMap.setMyLocationEnabled(true);
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(start, 15));
gd = new GoogleDirection(this);
gd.setOnDirectionResponseListener(new OnDirectionResponseListener() {
public void onResponse(String status, Document doc, GoogleDirection gd) {
mDoc = doc;
mMap.addPolyline(gd.getPolyline(doc, 3, Color.RED));
buttonAnimate.setVisibility(View.VISIBLE);
}
});
gd.setOnAnimateListener(new OnAnimateListener() {
public void onStart() {
textProgress.setVisibility(View.VISIBLE);
}
public void onProgress(int progress, int total) {
textProgress.setText((int)((float)progress / total * 100) + "% / 100%");
}
public void onFinish() {
buttonAnimate.setVisibility(View.VISIBLE);
textProgress.setVisibility(View.GONE);
}
});
textProgress = (TextView)findViewById(R.id.textProgress);
textProgress.setVisibility(View.GONE);
buttonRequest = (Button)findViewById(R.id.buttonRequest);
buttonRequest.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
v.setVisibility(View.GONE);
gd.setLogging(true);
gd.request(start, end, GoogleDirection.MODE_DRIVING);
}
});
buttonAnimate = (Button)findViewById(R.id.buttonAnimate);
buttonAnimate.setVisibility(View.GONE);
buttonAnimate.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
v.setVisibility(View.GONE);
gd.animateDirection(mMap, gd.getDirection(mDoc), GoogleDirection.SPEED_VERY_SLOW
, true, false, true, true
, new MarkerOptions().icon(BitmapDescriptorFactory.fromResource(R.drawable.car))
, true, false, null);
}
});
}
public void onPause() {
super.onPause();
gd.cancelAnimated();
}
}
And one more question, I want to use Google Place API to get somewhere's latitude and longitude as direction, and use my current location to create route.
This is my direction file:
public class PlaceActivity3 extends Activity {
final String ApiKey = "AIzaSyDQ6mA6vUHD3cMNqDoblES6q3dFHzNLqs4";
double latitude = 3.158847;
double longitude = 101.713837;
int radius = 1000;
String type = PlaceType.FOOD;
String language = "en";
String keyword = "japan restaurant food";
TextView textStatus;
ListView listView;
GooglePlaceSearch gp;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_place_1);
textStatus = (TextView)findViewById(R.id.textStatus);
listView = (ListView)findViewById(R.id.listView);
gp = new GooglePlaceSearch(ApiKey);
gp.setOnPlaceResponseListener(new OnPlaceResponseListener() {
public void onResponse(String status, ArrayList<ContentValues> arr_data,
Document doc) {
textStatus.setText("Status : " + status);
if(status.equals(GooglePlaceSearch.STATUS_OK)) {
ArrayList<String> array = new ArrayList<String>();
final ArrayList<String> array_photo = new ArrayList<String>();
for(int i = 0 ; i < arr_data.size() ; i++) {
array.add("Name : " + arr_data.get(i).getAsString(GooglePlaceSearch.PLACE_NAME) + "\n"
+ "Address : " + arr_data.get(i).getAsString(GooglePlaceSearch.PLACE_ADDRESS) + "\n"
+ "Latitude : " + arr_data.get(i).getAsString(GooglePlaceSearch.PLACE_LATITUDE) + "\n"
+ "Longitude : " + arr_data.get(i).getAsString(GooglePlaceSearch.PLACE_LONGITUDE) + "\n"
+ "Phone Number : " + arr_data.get(i).getAsString(GooglePlaceSearch.PLACE_PHONENUMBER));
array_photo.add(arr_data.get(i).getAsString(GooglePlaceSearch.PLACE_PHOTO));
}
ArrayAdapter<String> adapter = new ArrayAdapter<String>(PlaceActivity3.this
, R.layout.listview_text, array);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
Dialog dialog = new Dialog(PlaceActivity3.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.dialog_photo);
dialog.setCancelable(true);
final ImageView imgPhoto = (ImageView)dialog.findViewById(R.id.imgPhoto);
dialog.show();
gp.getPhotoBitmapByWidth(array_photo.get(arg2), 600, ""
, new OnBitmapResponseListener() {
public void onResponse(Bitmap bm, String tag) {
imgPhoto.setImageBitmap(bm);
}
});
}
});
}
}
});
gp.getNearby(latitude, longitude, radius, type, language, keyword);
}
}

For the current location, you can use the LocationServices's getLastLocation() function:
which should look something like this:
public class MainActivity extends ActionBarActivity implements
ConnectionCallbacks, OnConnectionFailedListener {
...
#Override
public void onConnected(Bundle connectionHint) {
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
mGoogleApiClient);
if (mLastLocation != null) {
mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude()));
mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude()));
}
}
}
https://developer.android.com/training/location/retrieve-current.html#last-known
OR, you can use the Google Maps Location Data API:
https://developers.google.com/maps/documentation/android/location
For your destination's lat/lng, you should use the The Google Geocoding API:
https://developers.google.com/maps/documentation/geocoding/#GeocodingResponses
