I have a osmdroid MapView with lots of markers that in many times overlap each other. Is there a way to bring selected marker to front with something like z-index?
我有一个osmdroid MapView，它有很多标记，在很多时候相互重叠。有没有办法将选定的标记带到像z-index这样的东西？

There is no z-index in osmdroid overlays, overlays are drawn from first to last => first is "behind", last is "in front". To push an overlay "in front", you have to change its relative position in the list of overlays.
osmdroid叠加层中没有z-index，从头到尾绘制叠加层=>第一个是“后面”，最后一个是“在前面”。要在“前面”按下叠加层，您必须在叠加列表中更改其相对位置。
If you are using OSMBonusPack, you could put your Markers in a FolderOverlay "myMarkersFolder". Then, to push an item "in front":
如果您使用的是OSMBonusPack，则可以将您的标记放在FolderOverlay“myMarkersFolder”中。然后，将项目“推到前面”：
AbstractList<Overlay> list = myMarkersFolder.getItems();
Overlay selectedMarker = list.remove(selectedMarkerIndex);
list.add(selectedMarker); //add at the end = in front
