Spinner : onItemSelected not called when selected item remains the same

I found out this work instead of the one provided

/** Spinner extension that calls onItemSelected even when the selection is the same as its previous value */
public class NDSpinner extends Spinner {

  public NDSpinner(Context context)
  { super(context); }

  public NDSpinner(Context context, AttributeSet attrs)
  { super(context, attrs); }

  public NDSpinner(Context context, AttributeSet attrs, int defStyle)
  { super(context, attrs, defStyle); }

  @Override public void
  setSelection(int position, boolean animate)
  {
    boolean sameSelected = position == getSelectedItemPosition();
    super.setSelection(position, animate);
    if (sameSelected) {
      // Spinner does not call the OnItemSelectedListener if the same item is selected, so do it manually now
      getOnItemSelectedListener().onItemSelected(this, getSelectedView(), position, getSelectedItemId());
    }
  }

  @Override public void
  setSelection(int position)
  {
    boolean sameSelected = position == getSelectedItemPosition();
    super.setSelection(position);
    if (sameSelected) {
      // Spinner does not call the OnItemSelectedListener if the same item is selected, so do it manually now
      getOnItemSelectedListener().onItemSelected(this, getSelectedView(), position, getSelectedItemId());
    }
  }
}

Ok, I finally found a solution, by creating my own class extending Spinner :

public class MySpinner extends Spinner {
OnItemSelectedListener listener;

public MySpinner(Context context, AttributeSet attrs) {
    super(context, attrs);
}

@Override
public void setSelection(int position) {
    super.setSelection(position);
    if (listener != null)
        listener.onItemSelected(null, null, position, 0);
}

public void setOnItemSelectedEvenIfUnchangedListener(
        OnItemSelectedListener listener) {
    this.listener = listener;
}
}
