AutoCompleteTextView OnItemClick position is always "0"

android, autocomplete

Solution

Don't ask me why, but the argument `position` in method `OnItemClickListener.onItemClick` holds the index relative to the `AutoCompleteTextView`'s dropdown list, not the position in your adapter array (in your case `regions`)!

So, to find the item's real `position` you must get the string selected in the dropdown and find its index in the adapter array:

String[] regions = ct.getRegions();
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, regions);
regionT.setAdapter(adapter);
regionT.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        String selected = (String) parent.getItemAtPosition(position);
        int pos = Arrays.asList(regions).indexOf(selected);
    }
});
