Add this code your Activity class

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_images);

    requestLocationPermission();
    //your other codes
}

private void requestLocationPermission() {

if (ContextCompat.checkSelfPermission(this, 
android.Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED &&
                ContextCompat.checkSelfPermission(this, 
                android.Manifest.permission.ACCESS_COARSE_LOCATION) ==
                PackageManager.PERMISSION_GRANTED) {

        } else {
            ActivityCompat.requestPermissions(this, new String[]
   {
    Manifest.permission.ACCESS_FINE_LOCATION, 
    Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

    //Checking the request code of our request
     //If permission is granted
    if (requestCode == 1) {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            //Displaying a toast
            Toast.makeText(this, "Permission granted now you can get the location", Toast.LENGTH_LONG).show();

            } else {
            //Displaying another toast if permission is not granted
            Toast.makeText(this, "Oops you just denied the permission", Toast.LENGTH_LONG).show();
           }
}
