Question

我猜应该丢失配置但是找不到它。我的更改是在主要活动上显示操作栏。

1 - 为根活动扩展ActionBarActivity。

public class MainActivity extends ActionBarActivity implements OnItemSelectedListener {

2 - 将minsdkversion更新为11

<uses-sdk
        android:minSdkVersion="11"
        android:targetSdkVersion="18" />

3 - 添加支持库android-support-v7-appcombat.jar

4 - 更改菜单xml。

<?xml version="1.0" encoding="utf-8"?>
<menu
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:yourapp="http://schemas.android.com/apk/res-auto"
>
    <item
        android:id="@+id/action_aboutbox"
        android:orderInCategory="100"
        android:showAsAction="always"
        android:title="@string/action_aboutbox"/>
    <item
        android:id="@+id/action_exit"
        android:orderInCategory="100"
        android:showAsAction="always"
        android:title="@string/action_exit"/>

</menu>

以下是运行app后的logcat日志。

我有什么需要做的吗？
