我有一个显示Feed项的Activity，它有一个上下文菜单来完成共享，添加到收藏夹等操作。我已将项目从上下文菜单移动到选项菜单，因此可以执行操作直接从操作栏执行。但是选项菜单没有显示在操作栏中（之前确实显示过）。我尚未在项目中添加任何操作，但它们应该显示在选项菜单中。

我的旧FeedItemActivity： http://pastebin.com/4rV9uq15
我有人可以帮助我，非常感谢你！
答案 0 :(得分：0)
如果你想在底部的操作栏中设置你的菜单，请在清单中使用它。
android:uiOptions="splitActionBarWhenNarrow"
或者如果你想在顶部操作栏中设置它，你必须使用xml，否则只有在点击菜单时它才会显示
答案 1 :(得分：0)
我认为问题是你从未夸大你的菜单
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
MenuInflater inflater = getMenuInflater();
Item item = mDbFeedAdapter.getItem(mItemId);
你创建了你的inflater但是没有使用它。将其更改为
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
MenuInflater inflater = getMenuInflater();
inflater.inflate((R.menu.mainmenu, menu); // you forgot this line here where mainmenu is your menu xml
Item item = mDbFeedAdapter.getItem(mItemId);
