所以我认为你想说的是。 有一个活动，比如说 MainActivity，它有地图，上面有大约 200 个标记。

并且所有这些都是单独初始化和分配的，您希望将它们全部放在一起，以便您只需搜索一个即可使用它们。

如果是这样，我的建议是。

创建一个单独的数据类来存储标记和其他相关数据。

data class MarkerInfo(
  //marker ID
  val id:Int,//marker Data
  val markerData:Marker,//other Data
  var otherData:String
)

现在开始存储和访问数据。

class MainActivity(){

  //at the top level,inside Activity
  // This will create an empty list of Marker Info
  var markerData = mutableListOf<MarkerInfo>()

  //Now take any function,let's say x
  private fun x(){
  //Mark a Marker on Map and assign it to a variable.
  val markerA : Marker = map.addMarker( MarkerOptions.position(somePosition))

  //we assign a function with id and other relevant data
  val x= markerData.size
  
  //store data in list
  markerData.add(MarkerInfo(x,markerA,"This is a very useful marker"))
 }
}

//now to access that marker.
//let's say there is a function named y.
private fun y(){
  //say we want to access the first marker
  //there are two ways to do so.

  //first method: you know some data which is already in there let's say we know id
  for(i in markerData){
  if(i.id == 1){
   Log.d("TAG",i.toString())
  }
 }
  //second method: directly
  Log.d("TAG",markerData[0].toString())
}
