Bild hochladen und andere Parameter auf Server

Question

Ich aktualisiere Bild und etwas Text auf Server mit Volley, aber das Bild wird nicht hochgeladen. Ich suchte danach und fand heraus, dass Bilder mit Multipart gesendet werden müssen und Volley nicht Multipart unterstützt. Gibt es eine Möglichkeit, Volley zu verwenden, um Bilder und Texte hochzuladen?

// Volley request 
 

 

 
StringRequest stringRequest = new StringRequest(Request.Method.POST, URLUtils.URL, 
 
       new Response.Listener<String>() { 
 
        @Override 
 
        public void onResponse(String response) { 
 

 

 
         try { 
 
          JSONObject jObj = new JSONObject(response); 
 
          if((jObj.getString("Ack").equals("1"))){ 
 
           Toast.makeText(getApplicationContext(), jObj.getString("msg"), Toast.LENGTH_SHORT).show(); 
 
           System.out.println(jObj.getString("image")); 
 
          } 
 

 

 
         } catch (JSONException e) { 
 
          // JSON error 
 
          e.printStackTrace(); 
 
          Toast.makeText(getApplicationContext(), "Json error: " + e.getMessage(), Toast.LENGTH_LONG).show(); 
 
         } 
 
        } 
 
       }, new Response.ErrorListener() { 
 
      @Override 
 
      public void onErrorResponse(VolleyError error) { 
 
       Toast.makeText(getApplicationContext(), "VolleyError" + error.toString(), Toast.LENGTH_LONG).show(); 
 
      } 
 
     }) { 
 
      @Override 
 
      protected Map<String, String> getParams() { 
 

 

 

 
       Map<String, String> params = new HashMap<String, String>(); 
 
       params.put("auth", "abc167"); 
 
       params.put("action", "editprofile"); 
 
       params.put("first_name", fname_et.getText().toString()); 
 
       params.put("last_name", lname_et.getText().toString()); 
 
       params.put("address", address_str); 
 
       params.put("zipcode", zip_et.getText().toString()); 
 
       params.put("phoneno", phone_et.getText().toString()); 
 
       params.put("device_token_id", "1234567890"); 
 
       params.put("device_type", "android"); 
 
       params.put("lat", lat_str); 
 
       params.put("long", lng_str); 
 
       params.put("photo", imagepath); 
 
       params.put("userid", "121"); 
 

 

 
       return params; 
 
      } 
 

 
     }; 
 

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