Android: the problem of top position when updating listview

The solution is simple, that is, when updating the listview, do not use setadapter. If this is the case, the position will be placed to the top; when you need to update the listview, use

Notifydatasetchanged method.

When using the notifydatasetchanged method, note that the update list is updated for all list items. Here there is a performance problem, so if you need to change only a single list item, we recommend that you do not use the notifydatasetchanged method. Instead, after obtaining the list item, adjust the control in it.
