如何解决此错误。希望你能指导我如何解决这个问题，我刚刚遇到了我的新手android编程。我只是遵循了一条户外运动中的代码并对其进行了一些修改。Json错误：java.lang.String类型的值sl_summ无法转换为JSON OBJECT
后我登录它将吐司JSON格式的消息错误：java.lang.String类型的值sl_summ不能在
的login.php
登录后转化成的JSONObject 吐司误差的 here is the screenshot
$user_sldtl = $db->getUserSLsummary($arclass, $loanclass, $accintreceivable,
$date, $year, $month, $br_code, $clientid);
If($user_sldtl != null) {
for($i = 0; $i < count($user_sldtl); $i++){
$sl_response["error"] = FALSE;
// $sl_response["sl_summ"]["sl_brcode"] = $user_sldtl[$i][0];
// $sl_response["sl_summ"]["sl_memid"] = $user_sldtl[$i][3];
$sl_response["sl_summ"]["sl_desc"] = $user_sldtl[$i][7];
$sl_response["sl_summ"]["tr_date"] = $user_sldtl[$i][10];
$sl_response["sl_summ"]["actual_balance"] = $user_sldtl[$i][14];
$sl_response["sl_summ"]["available_balance"] = $user_sldtl[$i][14];
json_encode($sl_response, true);
echo json_encode($sl_response, true);
//echo "<br>";
}
}
else {
// echo "Member's data not found"."<br />";
// echo "Var dump: ";
// var_dump($user);
// echo " ->No record found";
$sl_response["error"] = TRUE;
$sl_response["error_msg"] = "NO SL Details found!";
echo json_encode($sl_response);
}
JSON响应
该响应是由成员表。
{
"error":false,
"user":
{
"br_code":12,
"mem_id":13,
"username":"test",
"email":"[email protected]"
,"created_at":"2016-07-22 09:05:21"
}
}
这个响应是从sl_summ此用户具有在表

对不起，先生，但我不知道如何有一个可读的JSON响应。我只复制并粘贴到浏览器中。你能告诉我先生如何有一个更可读的JSON响应？就像在一些教程中一样..我只会编辑我的JSON响应先生。 – John
