What does the setTextFilterEnabled() method do?
It basically enables filtering for the contents of the given ListView. However, the caveat, as explained here is that the filtering doesn’t happen automatically. According to that link, you have to provide the filtering logic and then according to the AbsListView docs that outline that method, the adapter you call that method on must also implement Filterable.
Hope that helps…
According to the Android Developer Reference, the setTextFilterEnabled() method “enables or disables the type filter window. If enabled, typing when this view has focus will filter the children to match the users input.”
