Question

我使用以下代码来获取我当前的位置，没有GPS，但我想在敬酒中显示坐标。我试过这段代码，但它显示的是我的包名而不是坐标！

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

    // Define a listener that responds to location updates

    LocationListener locationListener = new LocationListener() {
        public void onLocationChanged(Location location) {
          // Called when a new location is found by the network location provider.
          //makeUseOfNewLocation(location);
        }

    public void onStatusChanged(String provider, int status, Bundle extras) {}

    public void onProviderEnabled(String provider) {}

    public void onProviderDisabled(String provider) {}

    };

    // Register the listener with the Location Manager to receive location updates
    locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
    Toast.makeText(getBaseContext(), "location is:"+locationListener, Toast.LENGTH_LONG).show();
}

Answer 1

您只有onLocationChanged()回调中的位置。

// Acquire a reference to the system Location Manager
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

// Define a listener that responds to location updates
LocationListener locationListener = new LocationListener() {

     public void onLocationChanged(Location location) {

        // Called when a new location is found by the network location provider.
        Toast.makeText(getBaseContext(), "location is:"+location, Toast.LENGTH_LONG).show();
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {}

    public void onProviderEnabled(String provider) {}

    public void onProviderDisabled(String provider) {}
};

// Register the listener with the Location Manager to receive location updates
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);

您正尝试烘烤locationListener对象。您必须拥有位置位置;烘烤时对象和toast location.getLatitude（）和location.getLongitude（）方法。

首先创建FMLocationListener类。

 private static class FMLocationListener implements LocationListener {

                public void onLocationChanged(Location location) {

                }

                public void onProviderDisabled(String provider) {

                }

            public void onProviderEnabled(String provider) {

            }

            public void onStatusChanged(String provider, int status, Bundle extras) {

            }

        }

然后使用以下代码

这会对你有帮助。

How to get current location in Android

在onLocationChanged方法中放置toast行。仅使用基于网络的位置使用此

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

对于基于GPS的位置，这一个

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

如何在android中获取当前位置？
