Menu items should specify a title（解决方法）

Just a wrong XML namespace! Try with:

<menu xmlns:android="http://schemas.android.com/apk/res/android"></menu>

And as G.T. suggested you should consider using appcompat on the showAsAction property (only needed if you want to support API < 11):

<menu xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto">    <item        android:id="@+id/item1"        android:icon="@drawable/ic_launcher"        app:showAsAction="ifRoom|withText"        android:title="@string/Add_New" /></menu>

Note:

The appcompat library is compatible with some old Android versions (API 7+) that can't handle the showAsAction property because they don't have the ActionBar (API < 11).

Try this:

<menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto"><item android:id="@+id/item1" android:icon="@drawable/ic_launcher" android:title="@string/Add_New" app:showAsAction="ifRoom|withText"></item></menu>

It works for me perfectly.
