Adding a button to the ActionBar with ActionBarSherlock
提问by noloman
I have been trying to add a button to the SherlockActionBar but I can't get it working.
我一直在尝试向 SherlockActionBar 添加一个按钮，但我无法让它工作。
This is the code that I have:
这是我拥有的代码：
@Override
public boolean onCreateOptionsMenu(Menu menu) {
android.view.MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, (android.view.Menu) menu);
return super.onCreateOptionsMenu(menu);
}
This is my menu.xmlcode:
这是我的menu.xml代码：
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/save_button"
android:title="i"
android:showAsAction="always" />
</menu>
This doesn't work, as even if I press the menu button, nothing shows up. Is there any other way? Am I making any mistake?
这不起作用，因为即使我按下菜单按钮，也没有任何显示。有没有其他办法？我犯了什么错误吗？

You are using Android's Menu and MenuInflater, but should be using the classes that come with ActionBarSherlock:
您正在使用 Android 的 Menu 和 MenuInflater，但应该使用 ActionBarSherlock 附带的类：
@Override
public boolean onCreateOptionsMenu(Menu menu) {
com.actionbarsherlock.view.MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.menu.menu, (com.actionbarsherlock.view.Menu) menu);
return super.onCreateOptionsMenu(menu);
}
It seems like you are intermingling the two right now. Make sure that you import only com.actionbarsherlock.view.Menu and com.actionbarsherlock.view.MenuInflater, and not its Android counterparts. I recommend you to do something like the following:
看来您现在正在将两者混在一起。确保您只导入 com.actionbarsherlock.view.Menu 和 com.actionbarsherlock.view.MenuInflater，而不是它的 Android 对应项。我建议您执行以下操作：
import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuInflater;
...
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.menu.menu, menu);
return super.onCreateOptionsMenu(menu);
}

I think in the menu.xml. Your item does not declare android:showAsAction attribute completely. You must declare it like this:
我想在menu.xml 中。您的项目没有完全声明 android:showAsAction 属性。你必须像这样声明它：
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/save_button"
android:title="i"
android:showAsAction="always|withText" />
</menu>
Since you did not specify any icon for the item action bar cannot display any item. By default icon are display than text.
由于您没有为项目操作栏指定任何图标，因此无法显示任何项目。默认情况下，图标显示而不是文本。
