使用MultiAutoCompleteTextView Validator

Question

我正在使用MultiAutoCompleteTextView的验证器，每当我点击建议时应用程序挂起。这是我的验证码。

  participants.setValidator(new AutoCompleteTextView.Validator() {
            @Override
            public boolean isValid(CharSequence charSequence) {
                if (!tempList.contains(item)){
                    tempList.add(item);
                    Log.e("itemadding", item.getEid());
                    return true;
                }

                else
                    return false;
            }

            @Override
            public CharSequence fixText(CharSequence charSequence) {
                return "";
            }
        });

participants.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
                item = adapter.getItem(position);
                participants.performValidation();

            }
        });

编辑：=这是堆栈跟踪...
