ContextMenu在Android 7中的位置混乱 [英] ContextMenu position is messed up in Android 7

问题描述

我有一个带有简单列表视图和上下文菜单的应用程序。 android 7之前的
，一切看起来都不错：

当单击列表底部的项目时：

当单击列表顶部的项目时：

但是机智的android 7 ...

当单击列表底部的项目时：

单击列表顶部的项目：

是否有任何变化

解决方案

我在某个地方找到了解决方案（不记得在哪里）。
问题出在新的上下文菜单和Holo主题之间。

解决方案详细信息：

我在values-v24文件夹中添加了以下样式：

 < resources> 
 
< style name = ContextPopupMenuStyleLight parent = @ android：style / Widget.Holo.Light.PopupMenu> 
< item name = android：overlapAnchor> true< / item> 
< / style> 
 
< style name = ContextPopupMenuStyleDark parent = @ android：style / Widget.Holo.PopupMenu> 
< item name = android：overlapAnchor> true< / item> 
< / style> 
 
< style name = AppTheme parent = AppTheme.Common> 
< item name = android：contextPopupMenuStyle> @ style / ContextPopupMenuStyleLight< / item> 
< / style> 
  

然后，以我的默认样式.xml我使用了一种名为

  AppTheme.Common 
   
 
 
这定义了我所有的应用样式，以及一个名为
 <的空样式; style name = AppTheme parent = AppTheme.Common /> 
  
，我将空样式用作默认应用样式。 
这样，在版本> 24的应用程序中，应用程序会使用有关上下文菜单重叠锚的额外项来解决此问题（将上下文菜单带到API 24之前的样子）
 
I have an app with a simple listview and context menu in it.
pre android 7, everything looks ok:

when clicking an item at the bottom of the list:


when clicking an item at the top of the list:


But wit android 7...

when clicking an item at the bottom of the list:


when clicking an item at the top of the list:


Was there any change in the position of the context menu?
解决方案
I found a solution for this somewhere (can't remember where).
The problem is between the new context menu and the Holo themes.

Solution Details:

I added a style in values-v24 folder that looks like:
<resources>

<style name="ContextPopupMenuStyleLight" parent="@android:style/Widget.Holo.Light.PopupMenu">
    <item name="android:overlapAnchor">true</item>
</style>

<style name="ContextPopupMenuStyleDark" parent="@android:style/Widget.Holo.PopupMenu">
    <item name="android:overlapAnchor">true</item>
</style>

<style name="AppTheme" parent="AppTheme.Common" >
    <item name="android:contextPopupMenuStyle">@style/ContextPopupMenuStyleLight</item>
</style>


Then, in my default styles.xml I used a style called 
AppTheme.Common
That defines all my app style, and an empty style called 
<style name="AppTheme" parent="AppTheme.Common" />
and I used that empty style as the default app style.
This way, on version > 24, the app uses this extra item regarding context menu overlap anchor to fix the issue (bringing context menu to what they looked like before API 24)
