我总是这样做，当TextView的为空：

I always get that textView is null when doing this:

public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.main, menu);

        MenuItem searchItem = menu.findItem(R.id.action_search);
        SearchView searchView = (SearchView) MenuItemCompat
                .getActionView(searchItem);

        int id = searchView.getContext().getResources().getIdentifier("android:id/search_src_text", null, null);
        TextView textView = (TextView) searchView.findViewById(id);
        textView.setTextColor(Color.WHITE);
}

谁知道为什么？

Anyone know why?
