Question

我有以下

ImageView mImageView;
mTxtDisplay = (TextView) findViewById(R.id.txtDisplay);
String url = "http://my-json-feed";
String xSession = "";

JsonObjectRequest jsObjRequest = new JsonObjectRequest
        (Request.Method.GET, url, null, new Response.Listener<JSONObject>() {

    @Override
    public void onResponse(JSONObject response) {
        /*


 {
      "message": "Session created",
      "session": "d4f7d26799c720eb6b09daa97a1b7e64",
      "result": {
        "id": "331339814848696320",
        "name": "Administrator",
        "email": "cyz@jsjsjsjsjsjsjsjsjsj.com",
        "username": "admin"
      }
    }
            */
      xSession = response.getString("session");
    }
}, new Response.ErrorListener() {

    @Override
    public void onErrorResponse(VolleyError error) {
        // TODO Auto-generated method stub

    }
});

// Access the RequestQueue through your singleton class.
MySingleton.getInstance(this).addToRequestQueue(jsObjRequest);

在响应上我可以看到response.getString（“session”）有值，但xSession没有填充？为什么xSession没有被填充？请帮忙！

Answer 1

Java语言区分大小写。你在哪里宣布xSession变量？那么，你要处理的正确的是xsession还是xSession？请查看或发布更相关的代码。

Answer 2

尝试在onResponce内记录回复。如果到达那里，那么确保xsession的值仅在收到响应后使用并且设置为
