MarkerOnClick数据为空

Question

我正在按照以下步骤设置标记，并且能够在地图上看到标记

 if (googleMap != null && mapFragment != null && googleMap.getProjection() != null) {
                                    googleMap.addMarker(new MarkerOptions().position(new LatLng(
                                            Double.parseDouble(storesWithDistance.getLatitude() + ""), Double.parseDouble(storesWithDistance.getLongitude() + "")
                                    )).title(storesWithDistance.getStoreName() + "").snippet(i + ""));
                                }

`marker.getTitle()` is returning `null` ..... Why is it happening ?

@Override
    public boolean onMarkerClick(Marker marker) {
        try {
            if (googleMap != null && mapFragment != null && googleMap.getProjection() != null) {

                String title = marker.getTitle();
                String snippet = marker.getSnippet();

                Log.d("","");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return true;
    }

您是否实现了 GoogleMap.OnMarkerClickListener 接口？ 您是否添加了这一行？ ：

googleMap.setOnMarkerClickListener(this)

如果您尝试将String title = marker.getTitle();从 try..catch 块中取出并用Log.d（）测试，该怎么办？
