java.lang.IllegalArgumentException:AppCompat不支持当前的主题功能

Question

我试图将项目从Eclipse迁移到Android工作室.最后我能够运行它,但在某个时刻我得到了这个例外,我在谷歌中没有发现这个:

73. MainActivity的行是:

setContentView(R.layout.activity_main);

如果可以,请告诉我.

Answer 1

替代@ sbaar的答案,

保持windowActionBar到false并加入windowNoTitle以及和它设置为true.

即

   <item name="windowActionBar">false</item>
   <item name="windowNoTitle">true</item>

Answer 2

去掉

<item name="windowActionBar">false</item>

从您的主题,然后确保您继承.NoActionBar主题,然后像平常一样设置您的工具栏.

Answer 3

确保您的主题是儿童Theme.AppCompat.NoActionBar,然后在styles.xml:

<style name="MyMaterialTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="windowNoTitle">true</item>
        ...
</style>

顺便说一句,这是支持库22.1的新问题.

Answer 4

检查你是否在super.onCreate()之后调用setContentView(),而不是之前.这有助于我的情况.

Answer 5

在Style.xml中使用此父级parent ="Theme.AppCompat.Light.NoActionBar"
