NOTA :come menzionato nella domanda precedente, la stringa JSON fornita deve essere nel formato corretto, ovvero avere una chiave per ogni oggetto (accesso, account) o averli in un singolo array (input). Sto dando una soluzione per entrambe le opzioni.
Principiante, ti sto fornendo 2 metodi separati in modo da poter gestire la stringa JSON in entrata a seconda di come la costruisci 2 oggetti in una singola stringa JSON o 2 oggetti in un array JSON.
Puoi scegliere la tua soluzione :)
Prova il codice, fammi sapere se hai bisogno di ulteriore aiuto e accetta la risposta.
OPZIONE1:2 oggetti in una singola stringa JSON
{
"login":{
"error":false,
"user":{
"br_code":12,
"mem_id":13,
"username":"novalyn",
"email":"[email protected]",
"created_at":"2016-07-22 09:05:21"
}
},
"accounts":{
"error":false,
"sl_summ":[
{
"sl_desc":"PA : Savings Account",
"tr_date":"2015-08-17",

"tr_date":"2015-08-28",
"actual_balance":"10129.43",
"available_balance":"10129.43"
}
]
}
}

Non ho accesso a tutti i file PHP interni che posso utilizzare per eseguire il codice PHP, quindi ho sostituito la maggior parte di tutte le chiamate di funzione con valori codificati come condivisi nel payload di risposta del campione. Ecco il codice per generare oggetti JSON nel formato OPTION1.
In breve, devi aggiungere ["login"] e ["accounts"] prima di tutti gli attributi secondari in $response in modo che vengano raggruppati nell'oggetto JSON corretto e avrai due oggetti JSON che possono essere analizzati sopra codice condiviso Android.
<?php
// json response array
$br_response = array("error" => FALSE);
$sl_response["error"] = FALSE;
$sl_response["sl_summ"] = array();
$arclass = "13";
$loanclass = "12";
$accintreceivable = "21";
// user is found
$response["login"]["error"] = FALSE;
$response["login"]["user"]["br_code"] = 12;
$response["login"]["user"]["mem_id"] = 13;
$response["login"]["user"]["username"] = "novalyn";
$response["login"]["user"]["email"] = "[email protected]";
$response["login"]["user"]["created_at"] = "2016-07-22 09:05:21";
for($i = 0; $i < 2; $i++){
$item = array();
$item["sl_desc"] = "PA : Savings Account";
$item["tr_date"] = "2015-08-17";
$item["actual_balance"] = "483.67";
$item["available_balance"] = "483.67";
$sl_response["sl_summ"][] = $item;
}
$response["accounts"] = $sl_response;
json_encode($response);
echo json_encode($response, true);
