刷新删除操作后，从一个ArrayList创建列表视图 [英] refresh listview created from an arraylist after delete operation

问题描述

我看到有关refreshin一个ListView太多的问题，我已经试过的议题每一个解决方案，但没有为我工作。

I have seen too many questions about refreshin a listview and I have tried every solution on the topics but none worked for me.

曾尝试 notifysetdatachange（）， invalidateviews ， refreshdrawablestate（），但没有奏效。

have tried notifysetdatachange(), invalidateviews, refreshdrawablestate() but none worked.

我有一个的ArrayList ，我从arraylist.and我希望它删除一个项目 longclick 术后从listview.but它不会消失。

I have an arraylist and after an longclick operation I am deleting an item from arraylist.and I want it to disappear from listview.but it does not.

但删除后，如果我打开另一个活动，回头到包含我的列表视图活动消失。

but after deletion if I open another activity and turn back to the activity which contains my listview it disappears.

所以我删除操作是成功的，我只是想知道如何刷新列表视图。

so my deletion operation is successful, I just want to know how to refresh listview.,

我没有张贴code，因为没有什么，我只是用独特的

I did not post a code because there is nothing unique I am just using

我有一个的ArrayList 名为 al_6 。我正与物体填充它。

I have an arraylist named al_6.I am filling it with objects.

然后我将它们发送到我的适配器像

then I send them to the my adapter like

adapter = new ContentSearchListAdapter(getActivity(), channels2,
                options);
        listview.setAdapter(adapter);

而当我想从我的ArrayList中删除对象。

and when I want to delete an object from my arraylist.

al_6.remove(position)

和前面说过的删除操作成功

and as I said before the deletion operation is successful
