Java Android-谷歌地图扩展-IllegalArgumentException

调用此createMarker（）方法时，我得到一个IllegalArgumentException：

以下是logcat输出：

我的MarkerOptions和GoogleMap值不为空？问题在于这一行：

marker = map.addMarker(options);

当我把上面的行注释掉时，应用程序会继续进行下一个活动。我的问题是什么？任何帮助都将不胜感激

Caused by: java.lang.IllegalArgumentException: no position in marker options

显然，您的

标记选项

没有位置。请致电

position（）

以提供放置标记的位置。

它对我有效

MarkerOptions mMarkerOptions = new MarkerOptions();
mMarkerOptions.position(new LatLng(lat, lang));
mMarkerOptions.anchor(0.5f, 0.5f);

MarkerOptions mMarkerOptions = new MarkerOptions();
mMarkerOptions.position(new LatLng(lat, lang));
mMarkerOptions.anchor(0.5f, 0.5f);
