MultiAutoCompleteTextView无法使用OnItemSelectedListener。

Question

ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(Application.getContext(), R.layout.report_add_list_item, ListUtil.asStringList(ContactServiceUtil.getContacts()));
    multiAutoCompleteContacts = (MultiAutoCompleteTextView) findViewById(R.id.multiAutoCompleteGuests);
    multiAutoCompleteContacts.setAdapter(adapter1);
    multiAutoCompleteContacts.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
    multiAutoCompleteContacts.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

        public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
            System.out.println("click");
        }

        public void onNothingSelected(AdapterView<?> adapterView) {
            return;
        }
    });

我没有进入onItemSelected方法。我需要通过位置获取已选择的列表项，以获取其ID。

Answer 1

AutoCompleteTextView（或MultiAutoCompleteTextView）永远不会触发OnItemSelectedListener。请使用OnItemClickListener代替：

setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Object item = parent.getItemAtPosition(position);
    }
});
