[英]fetching data using json volley
I am fetching data from db and want to set text. 我正在从数据库获取数据,并希望设置文本。 Values are getting fetched and displaying in url but setText not working, when I used JSONObject also same problem.
值被获取并显示在url中,但是setText不起作用,当我使用JSONObject时也遇到了同样的问题。 Where am I going wrong.?
我要去哪里错了? Below is my code and backend output.
下面是我的代码和后端输出。
{
"status": 200,
"db": {
"test_count": 2539,
"franchise_count": 2,
"patient_count": 1,
"invoice_count": 1,
"total_income": "12140",
"current_income": "12140",
"total_expense": null,
"current_expense": null,
"user_count": 2
}}
JsonObjectRequest objectRequest = new JsonObjectRequest(Request.Method.GET, url,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
progressDialog.dismiss();
try {
JSONObject object = new JSONObject();
u = object.getString("user_count");
user_count.setText(u);
} catch (JSONException e) {
Toast.makeText(getContext(),"No Records Found",Toast.LENGTH_LONG);
Log.e("Error", "Failed" +e.toString());
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
progressDialog.dismiss();
Log.e("Error", "Try Later" +error.toString());
Toast.makeText(getContext(),"No Records Found",Toast.LENGTH_LONG);
}
});
RequestQueue requestQueue = Volley.newRequestQueue(getActivity());
requestQueue.add(objectRequest);
}
Change your try block contents like below 如下更改您的try块内容
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
progressDialog.dismiss();
try {
JSONObject newObject=response.getJSONObject("db");
u = newObject.getString("user_count");
user_count.setText(u);
} catch (JSONException e) {
Toast.makeText(getContext(),"No Records Found",Toast.LENGTH_LONG);
Log.e("Error", "Failed" +e.toString());
e.printStackTrace();
}
}
