Moving the multiple marker using latitude and longitude from server - android

Single marker is moving perfectly but when adding more than one marker it is not working fine.

not able to track all the marker at the same time. I need to track all the markers at the same time like ola cab. Only single marker can be able to track, not more than one. Kindly help me to fix this issue.


Add all markers in a list when adding a marker in google map. Then whenever you need to update the position of a marker just find the current marker from the list and update position.

I can't figure how to make them clickable
I saw the documentation and the example and maybe i have to implement onMapClick method, but i don't know what put in it.
Does anyone know how to implement it or other way to make them clickable?
Thank you.

You can add a map click listener in your onMapReady-callback. In your onMapClick-method you set up a query at the selected point to see if there are any features in the symbollayer at that location. Then you get a list of features in that point that you can use. Here's a very condensed version of what I'm using:
private void handleMapClick(LatLng point){
if (myMapboxMap != null){
final PointF screenPoint = myMapboxMap.getProjection().toScreenLocation(point);
List<Feature> features = myMapboxMap.queryRenderedFeatures(screenPoint, SYMBOL_LAYER_ID);
if (!features.isEmpty()) {
//do stuff with features in feature list
}
}
}

I am using recreate() to refresh but why does it double refresh?

I am using recreate and refresh() to refresh page every minute but it double refreshes. First refresh is after 1minute, and the next refresh is after 2 sec first refresh.
i have tried changing the code inside refresh but didnt work.
private void loadalltrolley(){
StringRequest stringRequest = new StringRequest(Request.Method.GET, PRODUCT_URL,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONArray products = new JSONArray(response);
for(int i =0;i<products.length();i++){
JSONObject productObject = products.getJSONObject(i);
String gate_no = productObject.getString("gate_no");
String dock_name = productObject.getString("dock_name");
String dock_desc = productObject.getString("dock_desc") ;
int flight_arrival = productObject.getInt("flight_arrival");
int trolley_count = productObject.getInt("trolley_count");
Product product = new Product(gate_no,dock_name,dock_desc,flight_arrival,trolley_count);
allterminalList.add(product);
}
allterminaladapter = new ProductAdapter(alert.this,allterminalList);
recyclerView.setAdapter(allterminaladapter);
int count = allterminaladapter.getItemCount();
int i =0;
if (count>0)
{
displayNotification();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(alert.this,error.getMessage(),Toast.LENGTH_SHORT).show();
}
});
Volley.newRequestQueue(this).add(stringRequest);
refresh(60000);
}
public void refresh(int milliseconds){
final Handler handler = new Handler();
final Runnable runnable = new Runnable() {
#Override
public void run() {
recreate();
}
};
handler.postDelayed(runnable,milliseconds);
}
I want it to refresh 1 time only and not double refresh. I want to refresh the application after 1minute only.

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.

Algorithm for calculating distance between two location is taking too much

Firstly, i'm fetching some data from server database and getting some addresses which i'm reversing to location latitude and longitude, so i can calculate after that distance between my location latlng and theirs.
But for some reason Activity freezes at loading data and list is loading very slow with this feature. This is how i'm calculating distance between two location:
AndroidNetworking.get(AppConfig.GET_FIELDS_ORDER_BY_CITY.replace("city", tvCurrentLocation.getText().toString()))
.setPriority(Priority.IMMEDIATE)
.build().getAsJSONObject(new JSONObjectRequestListener() {
#Override
public void onResponse(JSONObject response) {
mFieldList.clear();
try {
if (!response.getBoolean("error")) {
JSONArray fieldsArray = response.getJSONArray("fields");
for (int i = 0; i < fieldsArray.length(); i++) {
JSONObject fieldObj = fieldsArray.getJSONObject(i);
Field field = new Field();
...
field.setCertificate(fieldObj.getString("certificate"));
Log.d("Location", fieldObj.getString("address"));
// If i delete from here
if (!fieldObj.getString("address").isEmpty()) {
LatLng latLng = AppUtils.getLocationFromAddress(SearchActivityV2.this,
fieldObj.getString("address"));
float dist = AppUtils.distFrom(44.8029925f, 20.495337f, (float) latLng.latitude, (float) latLng.longitude);
DecimalFormat df = new DecimalFormat("####0.0");
if (dist > 1000) {
double distance = AppUtils.calculationByDistance(new LatLng(44.8029925, 20.495337), latLng);
field.setDistance(df.format(distance) + " km");
} else {
String newValue = Double.toString(Math.floor(dist));
field.setDistance(newValue + " m");
}
} else {
field.setDistance("1000");
}
mFieldList.add(field);
}
// to here, list would load immediately, so
// something is not right with this
mFieldsListAdapter.notifyDataSetChanged();
}
} catch (JSONException e) {
Log.e(getClass().getSimpleName(), e.getMessage());
e.printStackTrace();
}
}
#Override
public void onError(ANError anError) {
Log.e(getClass().getSimpleName(), anError.getMessage());
}
});ield.setDistance(df.format(distance) + " km");
} else {
String newValue = Double.toString(Math.floor(dist));
field.setDistance(newValue + " m");
}
Any suggestions or tips what should i do? Thank you!

"onResponse" method works on main thread, So data parsing and heavy calculations may freeze app's UI thread.
Try to move all your parsing code and calculations to AsyncTask's "doInBackground" and update your adapter in "onPostExecute" because you must be on ui thread to perform this action.
code example:
private class ResponseParser extends AsyncTask<JSONObject, Void, Void> {
#Override
protected Void doInBackground(JSONObject... params) throws JSONException {
mFieldList.clear();
JSONArray fieldsArr = params[0].getJSONArray("fields");
if (!response.getBoolean("error")) {
JSONArray fieldsArray = response.getJSONArray("fields");
for (int i = 0; i < fieldsArray.length(); i++) {
JSONObject fieldObj = fieldsArray.getJSONObject(i);
Field field = new Field();
...
field.setCertificate(fieldObj.getString("certificate"));
Log.d("Location", fieldObj.getString("address"));
// If i delete from here
if (!fieldObj.getString("address").isEmpty()) {
LatLng latLng = AppUtils.getLocationFromAddress(SearchActivityV2.this,
fieldObj.getString("address"));
float dist = AppUtils.distFrom(44.8029925f, 20.495337f, (float) latLng.latitude, (float) latLng.longitude);
DecimalFormat df = new DecimalFormat("####0.0");
if (dist > 1000) {
double distance = AppUtils.calculationByDistance(new LatLng(44.8029925, 20.495337), latLng);
field.setDistance(df.format(distance) + " km");
} else {
String newValue = Double.toString(Math.floor(dist));
field.setDistance(newValue + " m");
}
} else {
field.setDistance("1000");
}
mFieldList.add(field);
}
// to here, list would load immediately, so
// something is not right with this
}
return null;
}
#Override
protected void onPostExecute(Void aVoid) {
super.onPostExecute(aVoid);
mFieldsListAdapter.notifyDataSetChanged();
}
}
Hope it helps!

Check if new value is same as the old value

I'm getting few values from a web service. The values keep changing every time I get the value from web service. I use a TimerTask in Serviceto get the values repeatedly.
I can't think of how to check if the value I got is the same as before.
public ArrayList getCo_ordinates(String deviceId) {
String URL_CO_ORDINATES = "http://192.168.1.42:8080/image/getDevicePosition?deviceId=" + deviceId;
// trimCache(getApplicationContext());
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.start();
final JsonArrayRequest request = new JsonArrayRequest(URL_CO_ORDINATES, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
try {
for (int i = 0; i < response.length(); i++) {
X = response.getJSONObject(i).getString("xCoordinate");
Y = response.getJSONObject(i).getString("yCoodinate");
System.out.println("xCoordinate" + X);
System.out.println("yCoodinate" + Y);
// tap();
addTap(Integer.parseInt(X), Integer.parseInt(Y));
}
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(context,""+e,Toast.LENGTH_SHORT).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError volleyError) {
Toast.makeText(getApplicationContext(), "Could Not connect to server", Toast.LENGTH_LONG).show();
}
});
requestQueue.add(request);
return null;
}

X = response.getJSONObject(i).getString("xCoordinate");
Y = response.getJSONObject(i).getString("yCoodinate");
System.out.println("xCoordinate" + X);
System.out.println("yCoodinate" + Y);
if(prev_x==X)
{
Log.d("same","value");
}
else
{
Log.d("different","value");
}
prev_x=X;
prev_y=Y;
