Question

IDE ：Android Studio 1.1.0

ENV ：使用Android API v10在USB连接手机上进行调试。

我正在尝试使用AppCompat来支持Android API v8及更高版本。绘制活动时编译很好但崩溃，说：

lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

...但是，在AndroidManifest.xml中我有：

    <application
        android:name=".objects.PikCMS"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/ThemeOverlay.AppCompat"
        >

谢谢你＆amp;请原谅我的沮丧。我一直在阅读很多相关但无益的信息。 } 8，（

其他信息

我不想强制使用特定的主题。
我想避免为不同的API版本使用不同的文件。但是，我不介意将相同属性的不同版本彼此相邻。
我在style.xml中为v11 中引入的项目（例如“buttonBarStyle”＆amp;“showDividers”）中出错。在阅读了这个问题之后，我原以为AppCompat会为pre11 API“填空”但是（在我的配置中）它不是。目前这些都被注释掉了 - 直到我找到如何在AppCompat中使用它们。同样，我遇到了布局文件的问题 - 这些有问题的属性被删除了。
活动类：Login.java extends：ActionBarActivity：。我也导入“ android.support.v7.app.ActionBarActivity ”，但我不确定是否需要全部，因为我没有隐含地使用操作栏（但我可能会在未来的）。
