这里给大家提供下绑定 spinner键值对的方法。

首先创建绑定模型BaseItem

public class BaseItem {    public BaseItem(Integer id,String value){        this.setId(id);        this.setValue(value);    }    private Integer id;    private String value;    public Integer getId() {        return id;    }    public void setId(Integer id) {        this.id = id;    }    public String getValue() {        return value;    }    public void setValue(String value) {        this.value = value;    }    //必须要重写，不然绑定spinner会有问题    @Override    public String toString() {        // TODO Auto-generated method stub        return value;    }}

接着，我封装了绑定Spinner的方法。

因为许多地方要用，所以就偷懒一下，做成一个方法了。

public class ControlHelper {    public static 
    
      void BindSpinner(Context context, T control, List
     
       list)    {        ArrayAdapter
      
        adapter=new ArrayAdapter
       
        (context, android.R.layout.simple_list_item_1,list);        ((T)control).setAdapter(adapter);    }    public static 
        
          void BindSpinner(Context context, T control, List
         
           list,Integer layout) { ArrayAdapter
          
            adapter=new ArrayAdapter
           
            (context, layout,list); ((T)control).setAdapter(adapter); }}
           
          
         
        
       
      
     
    

下面是我的实现：在MainActivity中

//region 读取仓库列表    //Spinner    @SuppressLint("HandlerLeak")    Handler handler1 = new Handler() {        @Override        public void handleMessage(Message msg) {//这里句简略了，绑定BaseItem            List
    
      list=new ArrayList<>();                BaseItem item = new BaseItem(wid,name);                list.add(item);            }//将BaseItem绑定到Spinner            BindSpinner.Bind(getBaseContext(),spinner,list);        }    };    //读取仓库列表    public void GetWarehouseAll(){        new Thread(new Runnable() {            @Override            public void run() {                try {//获取Spinner数据（webapi）                    String json = HttpWebapi.DoPost("/webapi/GetWarehouseAll", new ArrayList
     
      ());                    Message msg = Message.obtain();                    msg.obj = json;                    handler1.sendMessage(msg);                } catch (Exception e) {                    e.printStackTrace();                }            }        }).start();    }    //endregion
     
    

最后在onCreate中调用

//读取仓库列表        GetWarehouseAll();        //绑定了一个选中事件（用来测试）        spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {            public void onItemSelected(AdapterView
     parent, View view, int position, long id) {            /*             * ids是刚刚新建的list里面的ID             */                int ids = ((BaseItem) spinner.getSelectedItem()).getId();                System.out.println(ids);                Toast.makeText(getApplicationContext(), String.valueOf(ids), Toast.LENGTH_LONG).show();            }            @Override            public void onNothingSelected(AdapterView
     adapterView) {            }        });
