Android Google Maps v2: How to add marker with multiline snippet?

I have done with easiest way like below:

private GoogleMap mMap;

While adding marker on Google Map:

LatLng mLatLng = new LatLng(YourLatitude, YourLongitude);

mMap.addMarker(new MarkerOptions().position(mLatLng).title("My Title").snippet("My Snippet"+"\n"+"1st Line Text"+"\n"+"2nd Line Text"+"\n"+"3rd Line Text").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED)));

After that put below code for InfoWindow adapter on Google Map:

mMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {

      @Override
      public View getInfoWindow(Marker arg0) {
         return null;
      }

      @Override
      public View getInfoContents(Marker marker) {

        LinearLayout info = new LinearLayout(mContext);
        info.setOrientation(LinearLayout.VERTICAL);

        TextView title = new TextView(mContext);
        title.setTextColor(Color.BLACK);
        title.setGravity(Gravity.CENTER);
        title.setTypeface(null, Typeface.BOLD);
        title.setText(marker.getTitle());

        TextView snippet = new TextView(mContext);
        snippet.setTextColor(Color.GRAY);
        snippet.setText(marker.getSnippet());

        info.addView(title);
        info.addView(snippet);

      return info;
    }
});

Hope it will help you.

It looks like you will need to create your own "info window" contents to make that work:

1. Create an implementation of InfoWindowAdapter that overrides getInfoContents() to return what you want to go into the InfoWindow frame

2. Call setInfoWindowAdapter() on your GoogleMap, passing an instance of your InfoWindowAdapter

This sample project demonstrates the technique. Replacing my snippets with "foo\nbar" correctly processes the newline. However, more likely, you will just come up with a layout that avoids the need for the newline, with separate TextView widgets for each line in your desired visual results.
