设置App的首选项时遇到问题.

I run into a problem while I was settings up the Preferences for my App.

我想在ActionBar中有一个按钮(例如，保存)，但是我的ActionBar没有显示任何内容.我将此行放在onCreate方法中:

I would like to have a Button in the ActionBar (e.g. Save) but my ActionBar is not showing anything. I put this Line in the onCreate Method:

this.setHasOptionsMenu(true);

并实施了

public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
public boolean onOptionsItemSelected(MenuItem item)

方法也是如此.但是，它什么也没显示.

methods as well. However, it does not show anything.

推荐答案

请确保操作菜单中的按钮项布局如下:

Be sure your button item in your action menu layout something like:

<item
    android:id="@+id/action_save"
    android:orderInCategory="1"
    your_icon:showAsAction="always"
    android:icon="@drawable/icon_save"
   />
