【问题描述】：
我不是 Java 程序员，但我正在使用我发现的一些代码来创建一个带有多个标记的地图，以便我可以在我的应用程序中显示它。我希望定位地图，使其位于所有标记的中心，缩小以查看所有标记。我找到了一些应该执行此操作的代码，但我不知道将其放在我拥有的代码中的哪个位置。我也有点不确定我拥有的代码是否良好且高效。非常感激任何的帮助。我认为我需要的代码是
var markers = [];//some array
var bounds = new google.maps.LatLngBounds();
for (var i = 0; i < markers.length; i++) {
bounds.extend(markers[i].getPosition());
}
map.fitBounds(bounds);
我的代码是.....
