android – AutoCompleteTextView在onLongClick上剪切/复制/粘贴菜单上出现奇怪的裁剪问题
作者：互联网
我在显示剪切/复制/粘贴菜单时遇到问题.在AutoCompleteTextView中编写一个字符串后,在单词开始剪切/复制/粘贴菜单的第一个选择(LongClick)中.不幸的是,这个菜单与其原始位置脱节. 
有趣的是,当我点击左右选择指示符来改变单词的范围时,剪切/复制/粘贴菜单会自行渲染并更正其位置.现在可以单击剪切/粘贴/复制操作按钮. 
我试图改变一切,找到导致这个问题的原因,但没有任何改变.我认为有些东西会在裁剪时触发android的默认剪切/复制/粘贴菜单.不幸的是我找不到它是什么.
任何建议表示赞赏.谢谢.
事情可能会发生这个问题：
>在AndroidManifest.xml中 – >在相关活动中,“android：configChanges =”keyboard | keyboardHidden | orientation | screenLayout | uiMode | screenSize | smallestScreenSize“
>在AndroidManifest.xml中 – >在相关活动中,“android：theme = @ style / customTheme”
>在AndroidManifest.xml中 – >在相关活动中,android：windowSoftInputMode =“adjustPan”
>在MyDialogFragment.java中 – >同时设置actionBar

解决方法:
可能,剪切/粘贴/复制菜单会受到主题xml的影响. DialogFullScreenTheme样式包含重力场.您可以删除该字段,但必须检查所有对话框ui.
<style name="DialogFullScreenTheme" parent="android:Theme.Dialog">
<item name="android:layout_width">match_parent</item>
<item name="android:layout_height">match_parent</item>
<item name="android:windowAnimationStyle">@style/BlurDialogAnimation</item>
<item name="android:windowBackground">@null</item>
<!-- Remove this line -->
<item name="android:gravity">center</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">false</item>
</style>
