我想使用php从数据库中选择两个值，然后将其传递给android。
我想在AutoCompleteTextView中使用此值。
当我选择一个字段时，它将在AutoCompleteTextView上显示该字段并将ID存储在后台。
这是我的完整代码：-
package com.example.sachin.addvisit;

}
try {

while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result = sb.toString();
Log.e("Pass 2", "connection success ");

Log.e("Fail 2", e.toString());
}
return null;
}
@Override

params.add(new BasicNameValuePair("cl_wodcode", suid));
JSONObject json = jParser.makeHttpRequest(url_visitor, "GET", params);
int success1 = Integer.parseInt(json.getString("success4"));
Log.d("success4", json.toString());
if (success1 == 0) {
Snackbar.make(view, "Not Data Found", Snackbar.LENGTH_LONG).show();
}
if (success1 == 1) {
ownerObj = json.getJSONArray("visit");
for (int i = 0; i < ownerObj.length(); i++) {

Log.d("wt_wod_code",wt_party1);
//}
}
}
} catch (Exception e) {
}
return null;
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
这是我的API
<?php
include("connection.php");
$response = array();
//$id = $_REQUEST["wt_wod_code"];
//$uid=$id;
$result = mysql_query("SELECT DISTINCT cl_wodcode,cl_pname FROM clients") or die(mysql_error());
$count = mysql_num_rows($result);
// check for empty result
if ($count > 0) {
// looping through all results
// products node
$response["visit"] = array();
while ($row = mysql_fetch_array($result))
{
$Ordera = array();
$visit["cl_wodcode"] = $row["cl_wodcode"];
$visit["cl_pname"] = $row["cl_pname"];
$response["success"]=1;
// push single product into final response array
array_push($response["visit"], $visit);
}
$response["success4"] = 1;
// echoing JSON response
echo json_encode($response);
}
else
{
// no products found
$response["success"] = 0;
$response["message"] = "No picture found";
// echo no users JSON
echo json_encode($response);
}
?>
请建议我如何传递两个值？
最佳答案
它显示什么样的错误？
可以 ？
而且，您要从JSON解析的两个值（cl_pname和cl_wodcode）是否都是字符串？
关于php - 如何将两个值API传递给Android？，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/40042053/
