I have been struggling with trying to remove OnGlobalLayoutListener once it gets triggered but that throws an IllegalStateException. Since what I need is to scroll my recyclerView to the second element what I did was to check if it already have children and if it is the first time this is true, only then I do the scroll:

public class MyActivity extends BaseActivity implements BalanceView {
    ...
    private boolean firstTime = true;
    ...

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...

        ViewTreeObserver vto = myRecyclerView.getViewTreeObserver();
        vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                if (myRecyclerView.getChildCount() > 0 && MyActivity.this.firstTime){
                    MyActivity.this.firstTime = false;
                    scrollToSecondPosition();
                }
            }
        });
    }
    ...
    private void scrollToSecondPosition() {
        // do the scroll
    }
}

HTH someone!
