获取 google 地图 android 可见区域的标记数

Getting Number of Markers of visible region of google maps android

我们如何计算仅在 google 地图 android 的可见区域中显示的那些标记的数量?

var markers; //your markers
var map; //your map
var countInBoundingBox = 0; //the counter for the markers in bounding box

for (var i = markers.length, bounds = map.getBounds(); i--;) {
  if (bounds.contains(markers[i].getPosition())) {
    countInBoundingBox++;
  }
}

下次尝试提供 Minimal, Complete, and Verifiable example。 :-)
