요청 발리, 때때로 수신 된 데이터가 때때로

Question

Volley android 라이브러리로 요청하려하지만 가끔 데이터를 수신하고 때로는 실패합니다. 내가 잘못하고 있습니까?

는 여기에 내가 요청을

StringRequest strReq = new StringRequest(Request.Method.POST, 
      Config.EDIT_KERANJANG_URL, new Response.Listener<String>() { 

     @Override 
     public void onResponse(String response) { 
      Log.d(TAG, " Response: " + response.toString()); 

      try { 
       JSONObject jsonObject = new JSONObject(response); 
       Config.SUCCESS = jsonObject.getString("success"); 

       Log.e("error", "nilai sukses=" + Config.SUCCESS); 

       if (Config.SUCCESS.equals("1")) { 

        SharedPreferences.Editor editor = getSharedPreferences("CODE_RESUME_EDITK", MODE_PRIVATE).edit(); 
        editor.putString("code_resume_editk", "1"); 
        editor.apply(); 
        finish(); 

       } 
       else { 
        Log.e("error", "tidak bisa ambil data 0"); 
       } 

      } catch (Exception e) { 
       // TODO: handle exception 
       Log.e("error", "tidak bisa ambil data 1"); 
       Toast.makeText(KeranjangEditActivity.this, "Gagal menyimpan!", Toast.LENGTH_LONG).show(); 
      } 
     } 
    }, 

      new Response.ErrorListener() { 
       @Override 
       public void onErrorResponse(VolleyError error) { 
        Log.e(TAG, "Login Error: " + error.getMessage()); 
        Toast.makeText(KeranjangEditActivity.this, 
          "Gagal menyimpan!", Toast.LENGTH_LONG).show(); 
       } 

      }) 

    { 

     @Override 
     protected Map<String, String> getParams() { 
      // Posting parameters to login url 
      Map<String, String> params = new HashMap<String, String>(); 
      params.put("id_pesanan", sidPesanan); 
      params.put("quantity", sQuantity); 
      params.put("harga", sHarga); 

      return params; 
     } 

    }; 

를 만들기 위해 사용하고 코드입니다 그리고 여기이 목록 항목을 채우는 데 사용하고 내 사용자 지정 어댑터입니다.

도움을 주시면 감사하겠습니다.

Answer 1

시간 초과와 관련된 문제 인 것 같습니다. 보내는 요청에 대해 RetryPolicy를 설정할 수 있습니다. 이를 사용하십시오

strReq.setRetryPolicy(new DefaultRetryPolicy(5000, 
       DefaultRetryPolicy.DEFAULT_MAX_RETRIES, 
       DefaultRetryPolicy.DEFAULT_BACKOFF_MULT)); 

이 문제가 해결되기를 바랍니다.
