Spezifisches Profil anzeigen, wenn die Anmeldung erfolgreich war?

Question

Ich kann den spezifischen Benutzernamen in der Navigationsleiste nicht anzeigen.

http://192.168.100.5:84/api/academics/students ist die API für die Gesamtzahl der Studenten.

, wenn ich mit der spezifischen ID verwenden, wie unten angegeben, wird der Name angezeigt wird, aber es ist statisch mit der Bereitstellung der id.i will ID als Parameter in der Route http://192.168.100.5:84/api/academics/students/1(id) mit der spezifischen ID senden. Wie kann dies erreicht werden?

public static final String Navigation_URL = "http://192.168.100.5:84/api/academics/students/"; 

    private void makeJsonObjectRequest(int stud_id) { 
    String URL=Navigation_URL +stud_id; 
    Log.d("TAG","URL:"+URL); 
    StringRequest stringRequest = new StringRequest(Request.Method.GET, URL, 
      new Response.Listener<String>() { 
       @Override 
       public void onResponse(String response) { 
        try { 
         JSONObject jsonObject = new JSONObject(response); 
         StudentInformation studentInformation = new StudentInformation(); 
         studentInformation.Name = jsonObject.getString("NAME"); 
         profilename.setText(studentInformation.Name); 
        } catch (JSONException e) {

    RequestQueue requestQueue = Volley.newRequestQueue(this); 
    requestQueue.add(stringRequest);

Answer 2

Sie passieren ein Stringliteral StdID stattdessen benötigen Sie einen Wert zu übergeben.

Ändern Sie Ihre Methode makejsonobject, um einen Zeichenfolgenwert zu akzeptieren und zu übergeben.
