Android 从“设置”打开GPS后无法锁定GPS
我正在开发一个应用程序，要求用户启用GPS（如果不启用），然后将用户位置映射到地图上。我面临的问题是，当用户从设置中启用GPS并按下后退按钮后，对话框显示“位置用户位置”，但应用程序无法获取经度和纬度。虽然在这一阶段，如果我退出应用程序并再次启动它，并访问用户位置将显示在地图上的相同活动，那么它可以正常工作 以下是我使用的文件： GPSTracker.javaAndroid 从“设置”打开GPS后无法锁定GPS,android,gps,Android,Gps,我正在开发一个应用程序，要求用户启用GPS（如果不启用），然后将用户位置映射到地图上。我面临的问题是，当用户从设置中启用GPS并按下后退按钮后，对话框显示“位置用户位置”，但应用程序无法获取经度和纬度。虽然在这一阶段，如果我退出应用程序并再次启动它，并访问用户位置将显示在地图上的相同活动，那么它可以正常工作 以下是我使用的文件： GPSTracker.java public class GPSTracker extends Service implements LocationListener
