How to get GPS location?
提问by user3864894
I am trying to get the location but keep getting errors. Are any of you guys able to see where I'm going wrong? One of the errors is at least "method does not override or implement a method from supertype"- Thanks so much guys
我正在尝试获取位置，但不断收到错误消息。你们中的任何人都能够看到我哪里出错了吗？其中一个错误至少是“方法不会覆盖或实现超类型的方法”-非常感谢大家
MAIN
主要的
@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 class
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) {
}
}
In android manifest:
在安卓清单中：
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

You don't need to @Override the methods you are currently overriding. They're already abstract void, so by implementing the class, it assumes you are. Take a look at the Android tutorialfor obtaining location information.
您不需要 @Override 当前覆盖的方法。它们已经是抽象的 void，因此通过实现该类，它假定您是。看一下获取位置信息的Android教程。
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) {
}
}

LocationManager locationManager= (LocationManager)getSystemService(Context.LOCATION_SERVICE);
MyCurrentLoctionListener locationListener = new MyCurrentLoctionListener();
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,locationListener);
and change this line
并改变这一行
public class MyCurrentLoctionListener implements android.location.LocationListener {
