使用向spinner中ArrayAdapter綁定數據對象出錯報線程錯誤

1.實現的功能：就是實現一個下拉菜單 的功能，然後通過選中的文本獲取對應的id值；

2.操作中遇到的問題：

（1）向spinner中ArrayAdapter綁定數據對象出錯，ArrayAdapter<String>沒有問題，

例如：

String[] endSiteStr = {"請選擇","凱旋","馬安磚廠"};
adapterTemp = new ArrayAdapter<SiteModel>( getActivity(), android.R.layout.simple_spinner_item , endSiteStr);
endSiteSpinner.setAdapter(adapterTemp);

（2）如果是放ArrayAdapter<SiteModel>，就會報線程錯誤

SiteModel的具體內容：

所有的報錯信息：

解決辦法：

我是在碎片中使用onInitData（）方法，請求遠程數據並初始化數據；顧使用getActivity()來獲取活動

                       /*runOnUiThread(() -> {
                            startSiteSpinner.setAdapter(adapterTemp2);
                        });*/
                        getActivity().runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                startSiteSpinner.setAdapter(adapterTemp2);
                            }
                        });
