您需要在此活动中使用Theme.AppCompat主题（或其后代）。更改为Theme.AppCompat会导致其他错误。

我在我的应用程序中使用了appcompat v22.1.0，并且使用了Toolbar。当我使用Theme.AppCompat.Light.NoActionBar时，一切都很好。当我开始实现AlertDialog时，它产生了以下错误：

java.lang.IllegalStateException: 您需要使用Theme.AppCompat主题（或其子主题）才能使用此活动。

根据这个错误，我将我的主题更改为Theme.AppCompat并添加了以下内容：

false
true

到我的主题中。但是它产生了相同的错误。

Style.xml (旧)

Style.xml (新)

有人知道如何修复吗？
