在继承BaseSkinActivity下，使用SearchView问题。SearchView无效，无法展开搜索框。

[chenkezhao]

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main_menu,menu);
    SupportMenuItem searchItem = (SupportMenuItem)menu.findItem(R.id.menu_search);
    SearchView searchView = (SearchView) searchItem.getActionView();
    return super.onCreateOptionsMenu(menu);
}

使用了 setSupportActionBar(mToolbar);
