我的问题是我，简而言之，我无法将项目添加到操作栏！编译器不知道XML中的“项目”是什么，我无法弄清楚原因（这是我能说的，我可能是错的）。我所遵循的所有教程都告诉我，操作栏包含在API版本11或更高版本的主题“Holo”中，我已将其用于我的应用程序。
如果您需要更多信息，请向我询问。
提前致谢！
编辑：另外，我在官方Android Dev之后的应用程序中包含了'android-support-v4.jar'作为库。但是，其他网站并没有告诉我这样做。答案 0 :(得分：2)
您的ActionBar菜单不属于您的活动布局。删除＆lt;项目... /＆gt;在布局和
声明
<!-- Settings, should always be in the overflow -->
<Item
android:id="@+id/action_settings"
android:title="@string/action_settings"
android:showAsAction="never" />
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@+id/action_settings"
android:orderInCategory="100"
android:showAsAction="never"
android:title="@string/action_settings"/>
</menu>
在res / menu文件夹中创建一个名为main.xml的xml文件（实际上它可以是任何名称）并编写此代码。
并在Activity
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
并处理此设置菜单的点击事件，在您的活动中添加以下代码...
@Override
public boolean onOptionsItemSelected(MenuItem item) {
super.onOptionsItemSelected(item);
switch (item.getItemId()) {
case R.id.action_settings:
// Settings in ActionBar clicked
// start your Activity here
break;
default:
break;
}
return true;
}
答案 1 :(得分：0)
要添加到操作栏中的项目需要位于创建菜单xml的res / menu目录中（让我们称之为my_menu.xml）。在您的java文件中覆盖onCreateOptionsMenu(...)，然后确保在那里夸大菜单xml。
这样的事情：
@Override
public void onCreateOptionsMenu(Menu menu,
MenuInflater inflater) {
inflater.inflate(R.menu.my_menu, menu);
super.onCreateOptionsMenu(menu, inflater);
}
确保my_menu.xml看起来像这样：
<menu
xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@+id/action_settings"
android:title="@string/action_settings"
android:showAsAction="never"/>
</menu>
