Google android maps api v2 Show Marker Title Alway

Question

I have a google maps v2 in my android application and some markers on it. When user click one of these markers, a title popup comes. How can I show these titles always without user click?

Answer 1

Something like that:

googleMap.addMarker(new MarkerOptions()
    .position(new LatLng(latitude, longitude))
    .title("Your position")).showInfoWindow();

Answer 2

I'm not so good in some implementation but here is my code:

public BitmapDescriptor getBitmapFromView(String title) {
        View view = LayoutInflater.from(activity.getApplicationContext()).inflate(R.layout.marker_tooltip, null);
        ((TextView) view.findViewById(R.id.tooltips_title)).setText(title);

        //Get the dimensions of the view. In my case they are in a dimen file
        int width = activity.getResources().getDimensionPixelSize(R.dimen.tooltips_width);
        int height = activity.getResources().getDimensionPixelSize(R.dimen.tooltips_height);

        int measuredWidth = View.MeasureSpec.makeMeasureSpec(width, View.MeasureSpec.EXACTLY);
        int measuredHeight = View.MeasureSpec.makeMeasureSpec(height, View.MeasureSpec.EXACTLY);

        view.measure(measuredWidth, measuredHeight);
        view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());

        Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bitmap);

        view.draw(canvas);

        return BitmapDescriptorFactory.fromBitmap(bitmap);
    }

...
marker.setIcon(getBitmapFromView(marker.getTitle()));
...

I implemented this in a fragment in a map app with some variations. For example, with a custom Info Window and some events on the map but its implementation was required to show all marker title at the same time. Let me know if it was helpful for you too

the ACTIVITY of "activity.getResources().getDimensionPixelSize(R.dimen.tooltips_width)" variable is a property in the fragment

Just call Marker.showInfoWindow();. See https://developers.google.com/maps/documentation/android/marker#info_windows and https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/model/Marker#showInfoWindow()

Answer 4

You can do this:

Marker marker = mMap.addMarker(new MarkerOptions().position(currentPosition).title("Your text"));
marker.showInfoWindow();

Answer 5

For displaying marker titles on the map around the markers, none of the solutions I found on internet worked for me so I rolled up my sleeves and made this library which solves this problem for me, hopefully it will help others too:
