我在下面有一个json数组，并且想要选择相应的id作为数字并用文本填充微调器，当从spinner中选择一个也是动态的选项时，也就是在Spinner中显示的json数组并发送id到服务器，任何帮助请guzs

{
    "status": "success",

所以尝试使用volley库：

private void sendjsonRequest(){

        JsonArrayRequest jsonArrayRequest=new JsonArrayRequest(Request.Method.GET,"serverlink",null, new Response.Listener<JSONArray>() {

            @Override
            public void onResponse(JSONArray response) {

                String[] banks=parsejsonResponse(response);
                Spinner s = (Spinner) findViewById(R.id.Spinner01);
                ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_spinner_item, banks);
                s.setAdapter(adapter);


            }

        }, new Response.ErrorListener() {

            @Override
            public void onErrorResponse(VolleyError error) {

            }
        });

        requestQueue.add(jsonArrayRequest);

    }

private String[] parsejsonResponse(JSONArray array){

        String[] banks;

         if (array!= null){
            JSONArray data=array.getJSONArray("data");

            for (int i=0;i<data.length();i++){
                try {
                      JSONObject bank=data.getJSONObject(i);

                      String id=bank.getString("id");
                      String bankname=bank.getString("bankname")

                      banks.add(bankname);

                    }

                } catch (JSONException e) {

                }

            }
        }

        return banks;

    }

格式json就像这样的例子：

[{
    "status": "success",
    "message": "banks Fetched",
    "data": [
        {
          "id": 214,
          "bankname": "FIRST CITY MONUMENT BANK PLC"
        },
        {
          "id": 215,
          "bankname": "UNITY BANK PLC"  
        },
        {
          "id": 221,
          "bankname": "STANBIC IBTC BANK PLC"
        },
        {
          "id": 232,
          "bankname": "STERLING BANK PLC"
        },
        {
          "id": 301,
          "bankname": "JAIZ BANK"
        },
        {
          "id": 304,
          "bankname": "Stanbic Mobile"
        },
        {
          "id": 305,
          "bankname": "PAYCOM"
        }
    ]
}]

在 oncreate 中只需cal sendjsonrequest（）方法
