当我调用这个 createMarker() 方法时，我得到了一个 IllegalArgumentException：

private void createMarker(GoogleMap map, MarkerOptions options, OnMarkerCreateListener listener) {
    Log.e("LazyMarker", "Options var val: "+options);
    Log.i("LazyMarker", "GoogleMap Value:"+map);
    Log.i("LazyMarker", "OnMarkerCreateListener Value:"+listener);
    marker = map.addMarker(options);
    //Log.i("LazyMarker", "The value of Marker is:"+map.addMarker(options));
    if (listener != null) {
        listener.onMarkerCreate(this);
    }
}

这是 logcat 输出：

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

marker = map.addMarker(options);

当我评论应用程序上方的行时，它会继续进行下一个活动。我的问题是什么？任何帮助，将不胜感激。

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

显然，您MarkerOptions没有职位。请致电position()提供放置标记的位置。

它对我有用，

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