Java 操作栏背景显示在屏幕中间

我已经更改了操作栏的背景，但它看起来是这样的：

（我不能发布图片，因为我的声誉不超过10）

我有股票操作栏，我的操作栏背景显示在屏幕中间。我不知道怎样才能更好地描述它

你知道有什么问题吗

以下是my styles.xml：

您的操作栏样式可能没有被使用，因为您的主题没有链接到它，操作栏样式的父级也应该更改：

将此添加到AppBaseTheme中：

  <item name="android:actionBarStyle">@style/ActionBar</item>

@style/ActionBar

将操作栏样式声明更改为：

  <style name="ActionBar" parent="android:Widget.ActionBar">

然后发布您的布局xml，我们将看看是否可以进一步帮助您

谢谢您的帮助，现在它不会显示在屏幕中间，但actionbar的背景不会改变。顺便说一句，你想让我发布哪种布局？无论哪个活动的布局显示了这种奇怪的行为，加上清单。不幸的是，我无法发现问题，它对我来说与你自己的设置非常相似。我使用parent=“Theme.AppCompat”作为我的AppTheme父对象。对不起，我帮不上忙了！感谢您的帮助问题可能与背景有关，actionbar背景的尺寸是多少？
