With the new Maps Api Setting the Icon for a Markeris done with the following Code:
使用新的 Maps Api 设置标记图标是使用以下代码完成的：
MarkerOptions markerOptions = new MarkerOptions().icon(BitmapDescriptorFactory.fromResource(R.drawable.icon_location));
The icon can not be changed after a Marker was created. To change an icon remove the marker and readd it with a new image.
创建标记后无法更改图标。要更改图标，请移除标记并使用新图像读取它。

OverlayItem.setMarkerseems like the method you're looking for.
OverlayItem.setMarker似乎是您正在寻找的方法。
Note that there is (or used to be) a gotchayou need to be aware of; you first need to use Drawable.setBoundsto set the visible boundaries of the drawable before it can be rendered properly. Some fiddling might be needed to get it to centre; see this answer.
需要注意的是有（或曾经是）一个疑难杂症，你需要知道的; 您首先需要使用Drawable.setBounds来设置可绘制对象的可见边界，然后才能正确呈现。可能需要一些摆弄才能让它居中；看到这个答案。
