@Override
public boolean onOptionsItemSelected(MenuItem item) {

    Fragment fragment = null;

    switch (item.getItemId()) {
        case R.id.refresh_page:
            Fragment frag = null;
            mWebView.reload();
            //Toast.makeText(getContext(), "Обновить", Toast.LENGTH_LONG).show();


        case R.id.back_page:

            if (mWebView.canGoBack()) {
                mWebView.goBack();
                //Toast.makeText(getContext(), "Назад", Toast.LENGTH_LONG).show();
            }
            return true;


        case R.id.snd_msg_support:

    }

    FragmentManager fm = getFragmentManager();

    fragmentTransaction.replace(R.id.btnsndsupport, fragment);
    fragmentTransaction.commit();

    return super.onOptionsItemSelected(item);
}
