位置代码不再工作

Question

我在 android 6.0 中使用此代码来获得位置：

public class MainActivity extends AppCompatActivity implements LocationListener{
    protected LocationManager locationManager;
    protected LocationListener locationListener;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        if (checkPermission())
            locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
    }
    @Override
    public void onLocationChanged(Location location) {
        lati = location.getLatitude();
        longi = location.getLongitude();
    }
    @Override
    public void onProviderDisabled(String provider) {
        Log.d("Latitude", "disable");
    }
    @Override
    public void onProviderEnabled(String provider) {
        Log.d("Latitude", "enable");
    }
    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {
        Log.d("Latitude", "status");
    }
    private boolean checkPermission(){
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return false;
        }
        return true;
    }
}

我将程序属性中的权限设置为 true。

它曾经工作过，但现在它从未找到卫星或一般位置。

谷歌地图立即找到卫星。

我需要更改什么？

在你的代码中看到所有TODO注释吗？ 实现它。 您必须执行此操作才能在现代版本的 Andorid 上工作
