Android地图将多个标记设置为不可见 [英] Android maps set multiple markers invisible

问题描述

如何在Android Maps V2上隐藏多个标记?

How can I hide multiple markers on Android Maps V2?

我有10个标记. 5个特定类型的电影院和5个其他类型的电影院.

I have 10 markers. 5 a certain type of cinema and 5 another type.

如果我使用以下代码，则最后一个标记消失.

If I use the below code only the last marker disappears.

marker Cinema1，cinema2;

Marker cinema1,cinema2;

cinema1 = gMap.addMarker ......

cinema1 = gMap.addMarker......

cinema1 = gMap.addMarker ......

cinema1 = gMap.addMarker......

cinema2 = gMap.addMarker ......

cinema2 = gMap.addMarker......

cinema2 = gMap.addMarker ......

cinema2 = gMap.addMarker......

以此类推

点击事件

cinema1.setVisible(false);

cinema1.setVisible(false);

这只会将最后一个= = Cinema1的标记设置为不可见(很明显)，所以问题是如何在不声明每个标记的情况下将所有5个标记设置为不可见?

This only sets the last marker = to cinema1 to invisible (obviously) so the questions is how can I set all 5 markers invisible without declaring a Marker for each?

谢谢

推荐答案

您应创建带有标记的列表并在其帮助下进行操作.

You should create list with markers and manipulate with its help.

Marker dilers1,dilers2;
List<Marker> markers = new ArrayList<>();
dilers1 = mMap.addMarker(new MarkerOptions().position(new LatLng(55.755823,37.622315)).title("Melbourne"));
dilers2 = mMap.addMarker(new MarkerOptions().position(new LatLng(55.765823,37.612315)).title("Melbourne2"));
markers.add(dilers1);
markers.add(dilers2);

public void changer(){
   for (Marker mkr: markers) {
       mkr.setVisible(false);
   }

}
