android中的JSONArray无法读取此输出
从数据库获取数据并以<?php
require "con.php";
$result=mysql_query("SELECT * FROM registration_data WHERE profession like 'teacher'");
while($row=mysql_fetch_array($result))
{
$responce[]=array("name"=>$row[0],"password"=>$row[1]);
}
echo JSON_encode(array($responce));
$responce=array();
?>
//Output of code is:
[[{"name":"user1","password":"pass1"},{"name":"user2","password":"pass2"}]]
格式存储的正确方法是什么,以便我可以在android中的JSON
和JSONObject
中使用它。
我在android中的代码如下:
JSONArray
public class FetchData extends AsyncTask {
String data;
String dataParsed="";
String singleParsed="";
@Override
protected Object doInBackground(Object[] params) {
try{
URL url = new URL("http://10.0.2.2/android/test.php");
HttpURLConnection con= (HttpURLConnection) url.openConnection();
con.setRequestMethod("GET");
InputStream is=con.getInputStream();
BufferedReader br=new BufferedReader(new InputStreamReader(is));
String line="";
while(line !=null)
{
line=br.readLine();
data=data+line;
}
JSONArray JA=new JSONArray(data);
singleParsed= String.valueOf(JA.length());
for(int i=0;i<JA.length();i++)
{
JSONObject JO= (JSONObject) JA.get(i);
singleParsed="name: "+JO.get("name")+" \n"+"password: "+JO.get("email");
dataParsed=dataParsed+singleParsed;
}
}
catch(MalformedURLException e)
{
e.printStackTrace();
}
catch(IOException e)
{
e.printStackTrace();
}
catch (JSONException e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Object o) {
super.onPostExecute(o);
MapTest.tv.setText(this.data);
}
}
代码的输出显示为如果我显示数据变量但是我无法存储并在php
数组中获取它并按顺序显示
