为什么在模拟器下未始终在代号为一个的GoogleMap上触发MapListener [英] Why is the MapListener not always fired on Codename One GoogleMap under Simulator

问题描述

我的应用程序具有 ContainerMap （带有有效Javascript API密钥的GoogleMap），该文件放置在BorderLayout表单的中心位置。

My app features a ContainerMap (GoogleMap with valid Javascript API Key) that is laid in center location of a BorderLayout form.

super(new BorderLayout(BorderLayout.CENTER_BEHAVIOR_SCALE));
...
this.add(BorderLayout.CENTER_BEHAVIOR_CENTER, BorderLayout.center(userReportsMap));

我已经注册了 MapListener ，我想知道为什么在模拟器下放大或缩小时不总是将其触发？好像是在初始化GoogleMap并将MapListener添加到地图时，一开始就被触发了十二次，然后它不再触发了。我按下减号键和加号键来放大和缩小。

I have registered a MapListener and I wonder why it is not always fired when I zoom in or out under simulator ? It looks like it is fired a dozen of times right at the beginning when the GoogleMap is initialized and the MapListener is added to the map, and then it does not fire anymore. I press minus key and plus key to zoom out and in.

请注意：之后，我不会删除监听器或实例化地图。

Please note : I don't remove the listener or instantiate the map anywhere afterwards.

与之相反，在Android设备上，捏捏后似乎可以按预期工作。

On the contrary on an Android device it seems to work as expected when I pinch. So is it a limitation in the simulator due to the underlying Javascript map ?

任何提示表示赞赏，

推荐答案

我刚刚发布了一些Google Maps库的更改，以修复JS和模拟器中的一些竞态条件。这可能会为您解决问题。

I have just released some changes to the Google Maps lib to fix a couple of race conditions in JS and simulator. This might fix the issue for you.

此处是指向最新lib的直接链接。或者，您可以等待它（可能少于一天）出现在代号一个设置/扩展名中并在此进行更新。

here is a direct link to latest lib. Or you can wait (probably less than a day) for it to appear in Codename One Settings/Extensions and update through there.
