Hello,

This is too general. I would say you can handle thousand lines easily. If you notice a performance hit, then you will need to load only a subset of your data and probably use an auxiliar thread to load new data.

Notice that Ketai is based on ListViews as you can see in [Ketai’s source code](https://github.com/ketai/ketai/blob/master/src/ketai/ui/KetaiList.java#L28). You can broaden your search to the Android community if you search for ListView instead.
