Android – refresh tags on cluster manager

When the user navigates the map, the application will get a new location for him to view. However, the map does not use new tags to make it refreshing

After receiving JSON with locations, this method places them on the map

private void setMarkers(JSONObject response) {

    mClusterManager.clearItems();

    try {
        JSONArray venues = response.getJSONArray("venues");

        for (int i = 0; i < venues.length(); i++) {
            Venue venue = new Gson().fromJson(venues.getJSONObject(i).toString(), Venue.class);
            MarkerItem marker = new MarkerItem(venue.getLat(), venue.getLng(), venue, R.drawable.pin_quente);
            mClusterManager.addItem(marker);
        }

    } catch (JSONException e) {
        e.printStackTrace();
    }
}

The first request made them well, but the second request did nothing

resolvent:

use:

mClusterManager.cluster();

After marking

private void setMarkers(JSONObject response) {

    mClusterManager.clearItems();

    try {
        JSONArray venues = response.getJSONArray("venues");

        for (int i = 0; i < venues.length(); i++) {
            Venue venue = new Gson().fromJson(venues.getJSONObject(i).toString(), Venue.class);
            MarkerItem marker = new MarkerItem(venue.getLat(), venue.getLng(), venue, R.drawable.pin_quente);
            mClusterManager.addItem(marker);
        }

        mClusterManager.cluster(); 

    } catch (JSONException e) {
        e.printStackTrace();
    }
}
