Is it possible to show/hide Markers in Android Google maps api v2?

Question

I would like (in my Android app using Google maps api v2) to hide or show markers on my GoogleMap object according to a category, just like in the google maps web api, for example:

I have a GoogleMap with 50 Markers, 20 of them represent restaurants, 20 them represent bus stops, and 10 are cinemas.

Is it possible on Android google maps api v2 to do filtering on these markers, by hiding all the restaurant markers if we un-tick a checkbox for example?

I would like to do something like that but on my Android device using google maps api v2: http://www.geocodezip.com/v3_MW_example_categories.html

Sorry for the basic question but I am a beginner.

Solution 1

Try this way.

 Marker restuarantMarkers = gMap.addMarker(new MarkerOptions()
                .position(latlng)
                .title("MyPlace").icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_pin)).draggable(true));

On Click Event

  restuarantMarkers.setVisible(false);

This way can do using loop..

Let me know if it works for you.

Solution 2

You can use dialog if you want to filter your locations.

final Dialog dialog = new Dialog(context);
        dialog.setContentView(R.layout.dialog);
        Button bt_ok = (Button) dialog.findViewById(R.id.button1);
        final CheckBox cb1 = (CheckBox) dialog.findViewById(R.id.checkBox1);
        final CheckBox cb2 = (CheckBox) dialog.findViewById(R.id.checkBox2);
        dialog.setTitle("Category");

        bt_ok.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                mMap.clear();
                if (cb1.isChecked()){
                    mMap.addMarker(new MarkerOptions().position(new LatLng(44.109798, 15.242270)).title("Pin").icon(BitmapDescriptorFactory.fromResource(R.drawable.museum)));
                }
                if (cb2.isChecked()){
                    mMap.addMarker(new MarkerOptions().position(new LatLng(44.209798, 15.392270)).title("Pin 2").icon(BitmapDescriptorFactory.fromResource(R.drawable.restaurants)));
                }
                dialog.dismiss();
            }

        });

        dialog.show();

i'm not sure about the check box thing but this is code to add and remove markers

[Rachel Gallen]

You would have to find the latitude and longitude using geocoding. There is a Geocoder class in Android.

Hi Rachel, the code is bout adding or deleting markers according to the latitude and longitude, I do not need this. I would like to hide or show according a category or description or title or anything like this.

[Rachel Gallen]

see stackoverflow.com/questions/12905930/…

[Rami]

Thank you again Rachel but the links that you posted is not for Android, is for a web application :) I edited my question by putting your second link. I would like to do that using Android google maps not in a web page :)

[Rachel Gallen]

could you convert it somehow?

[Rami]

There is no direct conversion, that is why I am asking.

[Rachel Gallen]

[Rami]

@droid_dev: is it possible to store marker reference in arraylist or hashmap and then show hide marker by arry or hasmap. Means show all markers of contained in one hashmap

[moDev]

@Wikki Yes its possible
