Android-单击listview项目时锁定要映射的位置?
我有一个列表视图,其中包含了几家出租车公司。当用户单击出租车名称时,会显示一个警报对话框,要求他们预订、显示地图或取消。我试图实现的是,当用户单击ShowMap时,它从已经设置的字符串数组中获取位置,然后在地图上指向它。我不想让它找到我目前的位置。这可能吗?我已经有了一个mapview设置,目前只指向教程中的随机位置集 以下是我的代码:Android-单击listview项目时锁定要映射的位置?,android,listview,android-mapview,android-alertdialog,Android,Listview,Android Mapview,Android Alertdialog,我有一个列表视图,其中包含了几家出租车公司。当用户单击出租车名称时,会显示一个警报对话框,要求他们预订、显示地图或取消。我试图实现的是,当用户单击ShowMap时,它从已经设置的字符串数组中获取位置,然后在地图上指向它。我不想让它找到我目前的位置。这可能吗?我已经有了一个mapview设置,目前只指向教程中的随机位置集 以下是我的代码: ListTaxi Class : class Taxi { private String taxiName;
