[英]How to parse multiple Json data in android that coming from the server
* 我有疑問,是否有可能從android中的服務器解析多個json響應? 現在我正在開發一個將android應用程序與cakephp網站連接起來的項目。 我從服務器接收數據作為json編碼格式。並解析android中的json數據並顯示到視圖部分。 但現在我想從服務器傳遞多個json響應,怎么可能??? *
function commuterJson()
{
$upid=$_POST['upid'];
$ampm=$_POST['ampm'];
$this->loadModel('Userprofile');
$this->Userprofile->recursive = -1;
$ups = $this->Userprofile->find('first', array('conditions' =>
array('id' => $upid, 'status' => 'active')));
$todaysdata = $this->Requestcard->getRequestcardDataampm($upid, $ampm, $today);
$driverId=$todaysdata[0]['Requestcard']['driver_id'];
$vacencyId=$todaysdata[0]['Requestcard']['vacancycard_id'];
$driverDetails = $this->Userprofile->find('first', array('conditions' =>
array('id' => $driverId, 'status' => 'active')));
$vacancyDetails = $this->Vacancycard->find('first',
array('conditions' => array('id' =>$vacencyId )));
$vechicleId=$vacancyDetails['Vacancycard']['vehicledetail_id'];
$vechicleDetails=$this->Vehicledetail->find('first',
array('conditions' => array('id' => $vechicleId)));
echo json_encode($driverDetails);
echo json_encode($vechicleDetails);
echo json_encode($todaysdata);
exit();
}
我想將這三個jso編碼數據傳遞給android
echo json_encode($driverDetails);
echo json_encode($vechicleDetails);
echo json_encode($todaysdata);
當我嘗試只將一個json數據傳遞給android時,它正確得到我的android代碼
public void getData(View v)
{
HttpClient client = new DefaultHttpClient();
HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000);
HttpResponse response;
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost =
new HttpPost("http://10.0.2.2/Mebuddie/logins/login1");
httppost.setEntity
(new UrlEncodedFormEntity(nameValuePairs, HTTP.UTF_8));
response = httpclient.execute(httppost);
StringBuilder builder = new StringBuilder();
BufferedReader reader = new BufferedReader
(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
for (String line = null; (line = reader.readLine()) != null;)
{
builder.append(line).append("\n");
}
JSONTokener tokener = new JSONTokener(builder.toString());
JSONArray finalResult = new JSONArray(tokener);
Object type = new Object();
if (finalResult.length() == 0 && type.equals("both"))
{
System.out.println("null value in the json array");
}
else {
JSONObject json_data = new JSONObject();
for (int i = 0; i < finalResult.length(); i++)
{
json_data = finalResult.getJSONObject(i);
JSONObject menuObject = json_data.getJSONObject("Userprofile");
group_id= menuObject.getString("group_id");
id = menuObject.getString("id");
}
catch (Exception e) {
Toast.makeText(FirstMain.this,
"please enter a valid id or pswd",Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
我需要在我的android代碼中添加什么來接收多個json數據??? 如果有人知道請回復.................
public void getData(View v)
{
// TODO Auto-generated method stub
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://yourpagename");
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
}catch(Exception e){
Log.e("log_tag", "Error in http connection"+e.toString());
}
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result=sb.toString();
}catch(Exception e){
Log.e("log_tag", "Error converting result"+e.toString());
}
return null;
}
protected void onPostExecute(Void v) {
try{
JSONArray jArray = new JSONArray(result);
for(int i=0;i<jArray.length();i++)
{
JSONObject json_data = jArray.getJSONObject(i);
String id=json_data.getString("id");
String name=json_data.getString("name");
}
}
catch(JSONException e){
Log.e("log_tag", "Error parsing data "+e.toString());
}
}
在php端,你在json中編碼3個不同的數組。將它們全部放在一個數組中然后編碼那個單個數組
while($row=mysql_fetch_assoc($sql))
{
$output[$i]['id'] = $row['$driverDetails'];
$output[$i]['name'] = $row['$vechicleDetails'];
$output[$i]['image']=$row['$todaysdata'];
$i++;
}
打印(json_encode($輸出))
