Question

我在使用android 6.0（sdk 23）找到当前位置时遇到了问题。

在我写的主要活动中：

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

        locationListener = new LocationListener() {

            @Override
            public void onLocationChanged(Location location) {

textView.append("\n " + location.getLongitude() + " " + location.getLatitude());

            }

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

            }

            @Override
            public void onProviderEnabled(String provider) {

            }

            @Override
            public void onProviderDisabled(String provider) {
                Intent i = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                startActivity(i);
            }

        };

        configure_list();

还根据请求许可结果实施：

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        switch (requestCode) {
            case 10:
                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    // permission granted

                } else {
                    // permission denied

                }
                break;
            default:
                break;
        }
    }

    public void configure_list() {
        // first check for permissions
        if 

(ActivityCompat.checkSelfPermission(Applicazione.getInstance().getApplicationContext(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(Applicazione.getInstance().getApplicationContext(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION,Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.INTERNET} ,10);
        }
        return;
    }

    locationManager.requestLocationUpdates("gps", 5000, 0, locationListener);

}

但当前位置始终为0.是否有错误？有人能建议我吗？

我认为你应该使用Fused Location API

https://developers.google.com/android/reference/com/google/android/gms/location/FusedLocationProviderApi

查找当前位置Android 6.0
