我在我的应用程序中使用appcompat v22.1.0并使用工具栏。我使用时一切都很好Theme.AppCompat.Light.NoActionBar
。当我启动工具时AlertDialog
,它会产生如下错误:
java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

基于该错误,我将主题更改为Theme.AppCompat
并输入以下内容:
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
我的主题。但是它会产生相同的错误。
Style.xml(旧)
<resources>
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
</style>
</resources>
Style.xml(新)
<resources>
<style name="AppTheme" parent="Theme.AppCompat">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
</style>
</resources>
有人知道如何解决吗?

});
AlertDialog dialog = builder.create();
dialog.show();
}
}
When I start implement AlertDialog
我在哪里警报对话框的代码?
