特定のマーカーのためだけにInfoWindowAdapterを設定する方法

Question

マップビュー内で特定のマーカーの 'setInfoWindowAdapter'プロパティを使用しようとしていますが、 'マーカー2'と何らかの理由でタイトルの下に表示される不要なスペースがあります（マーカー2）（添付のスクリーンショットを参照）。これを防ぐために何ができるのでしょうか？

FragmentCustomMapview.java

public class FragmentCustomMapview extends android.support.v4.app.Fragment implements OnMapReadyCallback { 

    public FragmentCustomMapview() { 
     // Required empty constructor 
    } 

    GoogleMap mGoogleMap; 
    MapView mMapView; 
    SwitchCompat swt; 

    @Override 
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
     View v = inflater.inflate(R.layout.fragment_custommapview, container, false); 

     mMapView = (MapView) v.findViewById(R.id.map_custommapview); 
     mMapView.onCreate(savedInstanceState); 
     mMapView.getMapAsync(this); //this is important 

     swt = (SwitchCompat) v.findViewById(R.id.switch_map_custommapview); 

     return v; 
    } 

    @Override

       initMap(isChecked);

あなたMarkerは何のスニペットを持っていない場合は、あなたのLinearLayout infoにごTextView snippetを追加しないでください：

@Override 
public View getInfoContents(Marker marker) { 

    Context mContext = getActivity(); 

    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()); 
    title.setSingleLine(false); 

    info.addView(title); 

    if (marker.getSnippet() != null) { 
     TextView snippet = new TextView(mContext); 
     snippet.setTextColor(Color.GRAY); 
     snippet.setText(marker.getSnippet()); 
     snippet.setSingleLine(false); 

     info.addView(snippet); 
    } 

    return info; 
}
