[英]Refresh Master page of Android Master/Detail Flow from the detail part
I have a Master/Detail Activity in my Android Application. 我的Android应用程序中有一个主/细节活动。 The Master part shows a list of 10 items.
主要部分显示10个项目的列表。 On the detail part of each item there is a Button which can be used to delete that item from the list.
在每个项目的细节部分有一个Button,可用于从列表中删除该项目。 Content of My list is from an ArrayList.
我的列表的内容来自ArrayList。 I could delete any item from the ArrayList, but I am not able to update the master part.
我可以删除ArrayList中的任何项目,但我无法更新主要部分。
