spinner绑定的值一般分3种形式存放：

    1、存放在java页面的数组中：{“陕西”,”深圳”,”北京”}

private String[] province= {
   "江西", "湖南","西安"};
private String[][] city = {
   {
   "城市", "景点"}, {
   "张家界", "长沙"},
        {
   "吃喝玩乐", "biangbiang面"}};
private String[][][] zone = {
   {
   {
   "南昌", "赣州"}, {
   "庐山", "龙虎山"},},
        {
   {
   "黄石寨", "森林公园"}, {
   "临潼", "兵马俑"},}};

    2、存放在strings.xml文件中

最新的京东省市区XML点击下载就好,没办法还的花积分下载,最少两积分,这是我自己网上整理的,本着解决问题,却不能免费下载,抱歉.

    3、存放在数据库中，调用接口获得

    1、2是在一般的页面中比较常用，个人推荐第2种。这样你的页面看起来不会很乱/繁杂，而且一般把值存放在xml中，看起来比较专业。比如values文件夹中的：arrays.xml、colors.xml、ids.xml、strings.xml、styles.xml等等。第一种,本地的数组,对比而言第二种代码优化起来会更容易.

    3是需要调用接口，前几天遇到获取从接口获取数据,这几天闲了下来,记录自己当时遇到的问题和方法,防止以后用到就可以来看。

    下面就来对第三种方式的取值，进行说明。

//region 生产线
private void getLine() {
    Gson gson = new Gson();
    //获取生产线的接口
    String json = tool.doGet(Globe.Base_Biz_Url + "/getLine");
    //实体
    LineVo liveVo = gson.fromJson(json, new TypeToken<LineVo>() {
    }.getType());
    if (liveVo.status == 200) {
        try {
            JSONObject jsonObj = new JSONObject(json);
            String data = "";
            data = jsonObj.getString("data").toString();
            if (data != "") {
                List<Line> listLine = gson.fromJson(data, new TypeToken<List<Line>>() {
                }.getType());
                //默认==请选择  供用户选择生产线
                KeyValueInfo ky = new KeyValueInfo("请选择", "-1");
                LineList.add(ky);
                //遍历获取LineName
                for (int i = 0; i < listLine.size(); i++) {
                    KeyValueInfo keyValue = new KeyValueInfo(listLine.get(i).getLineName(), listLine.get(i).getLineCode());
                    //添加的到生产线的List集合
                    LineList.add(keyValue);
                }
                //自定义的Spinner布局用的是listview这里用到了适配器ArrayAdapter
                ArrayAdapter<KeyValueInfo> arrayAdapter = new ArrayAdapter<KeyValueInfo>(this, android.R.layout.simple_spinner_dropdown_item, LineList);
                spLine.setAdapter(arrayAdapter);
                spLine.setSelection(0, false);
                spLine.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
                    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                        String LineCode = ((KeyValueInfo) (spLine.getSelectedItem())).getValue();
                        //清除数据
                        WorkOrderList.clear();
                        spWorkOrder.setAdapter(null);
                        WorkCenterList.clear();
                        spWorkCenter.setAdapter(null);
                        GetWorkOrder(LineCode);//获取生产工单
                    }

犯了错，总之要改，改之后呢，最好还是记录。因为这些难题在后来的日子还是会遇到。不妨到时候回过头看看自己当时记录的错误。毕竟是自己的错，资以改正。

纸上得来终觉浅，书到用时方恨少。希望对你有所帮助。
