如何将BitmapDescriptor转换为android中的drawable for imageview

Question

您好我正在使用v2开发mapview，

从MarkerOptions对象我得到一个图标，比如......

MarkerOptions mo = markersList.get(pos);
BitmapDescriptor icon = mo.getIcon(); //Gets the custom icon set for this MarkerOptions object.

ImageView logo;

//how to assign icon to textview like using below code
logo.setBackgroundResource(icon) // It is not taking directly (BitmapDescriptor icon)

请帮忙。谢谢。
