Adapter Error Android Studio中的AlertDialog

Question

我遇到一些错误..我有2个recyclerview ..当我单击一个项目时，它会转到另一个recyclerview..i当在第二个recyclerview上单击一个项目时，我会在第二个recyclerview上发出警报对话框。一个项目已经在第二个recyclerview中工作了，但是当我尝试从第一个recyclerview中添加新项目到第二个recyclerview时，它运行良好，直到我单击我刚刚添加的第二个recyclerview上的项目，我得到了这个错误- ->

java.lang.IllegalStateException：您需要在此活动中使用Theme.AppCompat主题（或后代）。

如果第二个recyclerview中已存在该项目，我不会收到错误。当我向第二个recyclerview中添加新项目并单击以显示alerdialog时，错误就会出现。

通过我的MainActivity使用Tablet..i的那两个recyclerview..im尝试将getapplicationcontext更改为Mainactivity并更改清单 apptheme，但仍然相同。.

我的manifest.xml
