在ListView中添加项目时，UI会冻结 [英] UI freezes while adding items inside the ListView

问题描述

我正在使用ListView来填充其中的项目。我有一个搜索框，用于向服务器发送请求，
获取数据。来自服务器的响应数据将添加到ListView。当我不断向服务器发送请求时，我会不断获取数据并更新ListView。这会在更新时导致UI冻结问题。因此，当我在搜索框中输入
时，UI会冻结，直到ListView更新完成。有人可以告诉我为什么会发生这种情况吗？

解决方案

我必须看到你的代码，但我怀疑搜索是在同步而不是异步

I am using ListView to populate items inside it. I have a search box which I use to send a request to the server and get the data. The response data from the server will be added to the ListView. When I continuously sends a request to the server, I keep getting the data and updates the ListView. This causes UI freezing problem while updating. So, when I type something inside the search box, UI freezes until the ListView update finishes. Can anybody please tell me why this is happening?

解决方案

I would have to see your code but I suspect that the search is taking place synchronously instead of async
