Android Spinner 设置setOnItemSelectedListener时，竟会默认触发一次事件！

当然是关闭这坑货了：

       //禁止OnItemSelectedListener默认自动调用一次
spinnerDutyPerson.setSelection(0, true);
//放到TagContainer里
        spinnerDutyPerson.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                if (cjExecutorNames.size() > 0) {
                    //若要删除旧的联系人
                   /* preDutyPerson = cjExecutorNames.get(position);//记录责任人
                    List<String> tags = tagContainer.getTags();
                    if (tags.size() > 0) {
                        Iterator<String> iterator = tags.iterator();
                        String tag;
                        while (iterator.hasNext()) {
                            tag = iterator.next();
                            if (tag.equals(preDutyPerson)) {
                                iterator.remove();
                            }
                        }
                    }*/
                    List<String> tags = tagContainer.getTags();
                    tags.add(cjExecutorNames.get(position));
                    tagContainer.setTags(tags);
                }
            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {

            }
        });
