Update your OncreateView() method :

public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
    if (view != null) {
    if (view.getParent() != null) {
        ((ViewGroup)view.getParent()).removeView(view);
    }
    return view;
}

View v=inflater.inflate(R.layout.tests, container, false);

Hope this helps!!
