map是Google map的一个对象。我正在使用此处标记设置弹出窗口代码不可理解。请编辑并输入缺少的类?如public MoreInformation myMoreInformation;public PantryLocation location location;MapLocation Viewerits太长,而且不切题。我希望它更清晰。这个问题已经解决了讨论。查找详细信息。我已经看到了。这并没有满足我的疑问,我需要一个完全为int图像的弹出窗口。为此,你必须自定义弹出窗口。好的,我的意思是,我需要在点击位置用箭头弹出窗口。我使用了toast和自定义弹出窗口,但我无法在点击位置弹出窗口。你得到了吗
