android - 如何获取 GPS 位置？

Question

我正在尝试获取位置，但总是出现错误。你们中的任何人都能看到我要去哪里错了吗？其中一个错误至少是“方法没有覆盖或实现父类(super class)型的方法”——非常感谢你们

主要

@Override

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //get Your Current Location
    LocationManager locationManager=    (LocationManager)getSystemService(Context.LOCATION_SERVICE);
    MyCurrentLoctionListener locationListener = new MyCurrentLoctionListener();
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, (LocationListener) locationListener);

}

MyCurrentLoctionListener 类

public class MyCurrentLoctionListener implements LocationListener {

    @Override
    public void onLocationChanged(Location location) {
        location.getLatitude();
        location.getLongitude();

        String myLocation = "Latitude = " + location.getLatitude() + " Longitude = " + location.getLongitude();

        //I make a log to see the results
        Log.e("MY CURRENT LOCATION", myLocation);

    }

    @Override
    public void onStatusChanged(String s, int i, Bundle bundle) {

    }

    @Override
    public void onProviderEnabled(String s) {

    }

    @Override
    public void onProviderDisabled(String s) {

    }
}

在安卓 list 中:

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

您不需要@Override 当前正在覆盖的方法。它们已经是抽象的 void，所以通过实现类，它假设你是。看看 Android tutorial用于获取位置信息。

public class MyCurrentLoctionListener implements LocationListener {

    public void onLocationChanged(Location location) {
        location.getLatitude();
        location.getLongitude();

        String myLocation = "Latitude = " + location.getLatitude() + " Longitude = " + location.getLongitude();

        //I make a log to see the results
        Log.e("MY CURRENT LOCATION", myLocation);

    }

    public void onStatusChanged(String s, int i, Bundle bundle) {

    }

    public void onProviderEnabled(String s) {

    }

    public void onProviderDisabled(String s) {

    }
}
