Out of the box, the AutoCompleteTextView
widget does not seem to be able to match the input string in the middle of a list value - the matches are always made at the beginning; e.g., entering "ar
" matches "argentina
", but not "hungary
".
How can I search for the text in the middle of the word ? Can anyone give me an idea ?
Thanks in advance !
You would need to write a custom Filter
class and implement the performFiltering
method yourself. This method takes a CharSequence
argument, which you can use to perform whatever String operations you need in order to generate a list of matches from your dataset (in your case, you could use String.contains
instead of String.startsWith
). The performFiltering
function is not run on the UI thread.
You then return your list of matches as a FilterResults
object, which contains an Object
values (your list of matches, probably an ArrayList
) and an int
count which is the size of your list of matches.
Finally, implement the publishResults
callback method, which returns once the worker thread has generated the list of matches, allowing you to call notifyDataSetChanged
on your AutoCompleteTextView's adapter so that it can display the results.
