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

Does anybody know how to add multiline snippet to Google Maps marker? That's my code for adding markers:

map.getMap().addMarker(new MarkerOptions()
    .position(latLng()).snippet(snippetText)
    .title(header).icon(icon));

I want snippet to look like this:

| HEADER |
|foo     |
|bar     |

but when I'm trying to set snippetText to "foo \n bar", I see just foo bar and I don't have any ideas how to make it multiline. Can you help me?

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.

Building on Hiren Patel's answer as Andrew S suggested:

 mMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {

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

        @Override
        public View getInfoContents(Marker marker) {

            Context context = getApplicationContext(); //or getActivity(), YourActivity.this, etc.

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

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

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

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

            return info;
        }
    });

Based on Hiren Patel solution. This code creates a TextView from layout, not from zero. One significant difference: if you have clusters, you won't see a void label when clicking at a cluster.

override fun onMapReady(googleMap: GoogleMap) {
    this.googleMap = googleMap
    ...

    // Use this anonymous class or implement GoogleMap.InfoWindowAdapter.
    googleMap.setInfoWindowAdapter(object : GoogleMap.InfoWindowAdapter {
        override fun getInfoContents(marker: Marker): View? {
            return null
        }

        override fun getInfoWindow(marker: Marker): View? =
            if (marker.title == null)
                null
            else {
                val inflater = LayoutInflater.from(context)
                val view = inflater.inflate(R.layout.layout_marker, null, false)
                view.label.text = marker.title
    
                view
            }
    })

layout_marker.xml:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/label"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingLeft="5dp"
    android:paddingRight="5dp"
    android:paddingTop="4dp"
    android:paddingBottom="4dp"
    android:textColor="$f0f0f0"
    android:textSize="12sp"
    tools:text="Marker"
    android:background="#00aaee"
    />

Same code, but in Kotlin:

    mMap?.setInfoWindowAdapter(object : InfoWindowAdapter {
		override fun getInfoWindow(arg0: Marker): View? {
			return null
		}
		
		override fun getInfoContents(marker: Marker): View {
			val info = LinearLayout(applicationContext)
			info.orientation = LinearLayout.VERTICAL
			val title = TextView(applicationContext)
			title.setTextColor(Color.BLACK)
			title.gravity = Gravity.CENTER
			title.setTypeface(null, Typeface.BOLD)
			title.text = marker.title
			val snippet = TextView(applicationContext)
			snippet.setTextColor(Color.GRAY)
			snippet.text = marker.snippet
			info.addView(title)
			info.addView(snippet)
			return info
		}
	})

mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {

        @Override
        public void onMapClick(LatLng point) {

            // Already two locations
            if (markerPoints.size() > 1) {
                markerPoints.clear();
                mMap.clear();
            }

            // Adding new item to the ArrayList
            markerPoints.add(point);

            // Creating MarkerOptions
            MarkerOptions options = new MarkerOptions();

            // Setting the position of the marker

            options.position(point);
            if (markerPoints.size() == 1) {
                options.icon(BitmapDescriptorFactory.fromResource(R.mipmap.markerss)).title("Qtrip").snippet("Balance:\nEta:\nName:");
                options.getInfoWindowAnchorV();
            } else if (markerPoints.size() == 2) {
                options.icon(BitmapDescriptorFactory.fromResource(R.mipmap.markerss)).title("Qtrip").snippet("End");
            }
            mMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {

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

                @Override
                public View getInfoContents(Marker marker) {

                    Context context = getApplicationContext(); //or getActivity(), YourActivity.this, etc.

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

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

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

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

                    return info;
                }
            });
            mMap.addMarker(options);
