<item android:id="@+id/menu_item_signup" allergy:showAsAction="ifRoom" android:title="@string/sign_up"> </item>

推荐答案

您必须加入项目前清除菜单对象。我有同样的问题，这是我已经找到了最好的解决方案。

You must clear your menu object before adding items. I had the same problem and this was the best solution that I've found.

@Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { menu.clear(); inflater.inflate(R.menu.signin, menu); super.onCreateOptionsMenu(menu, inflater); }
