1. 确认已经获取了定位权限。

2. 使用新的LocationCallback API替换旧的LocationListener API。

3. 禁用应用程序的后台限制，以确保定位服务在应用程序后台运行时继续工作。

以下是使用新的LocationCallback API的示例代码：

LocationRequest locationRequest = LocationRequest.create(); locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY); locationRequest.setInterval(10000); locationRequest.setFastestInterval(5000); locationRequest.setNumUpdates(1);

FusedLocationProviderClient fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this);

fusedLocationProviderClient.requestLocationUpdates(locationRequest, new LocationCallback() { @Override public void onLocationResult(LocationResult locationResult) { if (locationResult == null) { return; }

    Location location = locationResult.getLastLocation();
    // Do something with the location
}

}, Looper.getMainLooper());

请注意，该示例需要使用Google Play服务库。确保在应用程序的build.gradle文件中包含以下依赖项：

implementation 'com.google.android.gms:play-services-location:18.0.0'
