I am developing an Application of JSON object Which Returns data into ListView.
if json have data then show data in listview..if dont have date then application is crashes.my application is crashes when json is empty.how to resolve this problem..thanx in advancce
here is android code..
public class EmployeePaymentHistory extends Fragment {
HttpParse httpParse = new HttpParse();
ProgressDialog pDialog;
ListView CategoryListView;
ProgressBar progressBar;
List<String> IdList = new ArrayList<>();
private String TAG = EmployeePaymentHistory.class.getSimpleName();

//Calling method to filter Student Record and open selected record.
HttpWebCall(TempItem);
// Add Click listener on Delete button.

$tem = $row;
$json = json_encode($tem);
}
} else {

You need to give the response output same as you are parsing in android side. If you are trying to find a Json object of key name which is not in response then it will crash.
In this scenario you need to handle manually, the values you think it will be null or empty then handle using normal if statements.
Suppose jsonObject.getString("date") object is not fount then using if statements you can handle.
if(jsonObject.getString("date") != null){
//code here
}

I am new to programming and my current app gets data from my server for a single data only and input it into textview. But now I have successfully created a php script that encodes JSONArray with multiple values but I dont know how to get the values to the android code via looping and I also dont know how to populate my listview.
Sample JSON
[{"lnumber":"2","violation":"2"},{"lnumber":"2","violation":"No Helmet"}]
PHP Script
$result = array();
$sql = "SELECT lnumber,violation FROM violators WHERE
lnumber='".$lnumber."'";
$stmt = $con->prepare($sql);
$stmt->execute();
$stmt->bind_result($lnumber, $violation);
while($stmt->fetch())
{
$temp = [
'lnumber'=>$lnumber,
'violation'=>$violation
];
array_push($result, $temp);
}
echo json_encode($result);
How am I currently getting data from server and displaying it using only textview.
Android Code
StringRequest stringRequest = new StringRequest(url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
loading.dismiss();
showJSON(response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getViolation.this,error.getMessage().toString(),Toast.LENGTH_LONG).show();
}
});
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}
private void showJSON(String response)
{
try
{
String lnumber;
String violation;
JSONObject jsonObject = new JSONObject(response);
JSONArray result = jsonObject.getJSONArray(getConfig.JSON_ARRAY);
JSONObject violationData = result.getJSONObject(0);
lnumber = violationData.getString(getConfig.KEY_LNUMBER);
violation = violationData.getString(getConfig.KEY_VIOLATION);
textViewResult.setText("License Number:\t"+lnumber+"\nViolation:\t"+violation);
}
PS:
My Listview id is listView. If anyone can help me how to display multiple data from the server to the listview would be a very great help!
1.Your JSON root tag is [] . You must use JSONArray . It is not JSONObject .
2.Your sample did not contain datetime key in your JSONObject .
Try this
DataBean
public class DataBean {
/**
* lnumber : 2
* violation : 2
*/
private String lnumber;
private String violation;
public String getLnumber() {
return lnumber;
}
public void setLnumber(String lnumber) {
this.lnumber = lnumber;
}
public String getViolation() {
return violation;
}
public void setViolation(String violation) {
this.violation = violation;
}
}
Adapter
public class MyAdapter extends BaseAdapter {
private List<DataBean> beanList;
private LayoutInflater inflater;
private Context context;
public MyAdapter() {
}
public MyAdapter(List<DataBean> beanList, Context context) {
this.context = context;
this.beanList = beanList;
this.inflater = LayoutInflater.from(context);
}
#Override
public int getCount() {
return beanList == null ? 0 : beanList.size();
}
#Override
public Object getItem(int position) {
return beanList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = inflater.inflate(R.layout.your_layout, null);
DataBean dataBean = beanList.get(position);
text.setText(dataBean.getLnumber() + dataBean.getViolation());
return view;
}
}
Activity
private List<DataBean> beanList = new ArrayList<>();
private ListView listView;
private void showJSON(String response) {
listView = (ListView) findViewById(R.id.listview);
try {
String lnumber;
String violation;
String datetime;
DataBean dataBean = new DataBean();
JSONArray jsonArray = new JSONArray(response);
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
lnumber = jsonObject.getString("lnumber");
violation = jsonObject.getString("violation");
dataBean.setLnumber(lnumber);
dataBean.setViolation(violation);
beanList.add(dataBean);
}
MyAdapter myAdapter = new MyAdapter(beanList,MainActivity.this);
listView.setAdapter(myAdapter);
} catch (JSONException e) {
e.printStackTrace();
}
}
so you want to fetch the json from the php script u have.
use AsyncDataClass to fetch json from your php script and as you are new to programming first read about AsyncDataClass and then try to print the json you fetched from the script using Log.d("","") then proceed to next step.

Add the following line to your onPostExecute:
mAdapter.notifyDataSetChanged();
You need to notify your adapter that the data had changed.
See the docs.
Regarding the ProgressBar, you need to put it under some Layout in your activity_best_links layout.
The best way would be to not create it programatically, but add it to your xml layout file, see example here, and then play with its visibility via mProgress.setVisibility();
I've currently got an application that pulls data from a mysql database and displays it in raw JSON format. I'm currently working on pushing this data into a String variable and displaying it on a Listview on a specific activity.
Problem is, when trying to display this data, my Listview is not populating; I'm sure the variable is not empty as the if statement would have captured this.
Here is snippet of MainActivity code:
//Methods to grab information from abhandym_DB database
public void getJSON(View view){
new BackgroundTask().execute();
}
public void parseJSON(View view){
if(JSON_String==null){
Toast.makeText(getApplicationContext(), "First Get Json", Toast.LENGTH_LONG).show();
}else{
Intent intent = new Intent(this,Test.class);
intent.putExtra("JSON_Data",JSON_String);
startActivity(intent);
}
}
class BackgroundTask extends AsyncTask<Void,Void,String>{
String json_url;
#Override
protected void onPreExecute() {
json_url = "http://abhandyman.x10host.com/json_get_data.php";
}
#Override
protected String doInBackground(Void... params) {
try {
URL url = new URL(json_url);
HttpURLConnection httpURLConnection = (HttpURLConnection)url.openConnection();
InputStream inputSteam = httpURLConnection.getInputStream();
BufferedReader buffereredReader = new BufferedReader(new InputStreamReader(inputSteam));
StringBuilder stringBuilder = new StringBuilder();
while((JSON_String = buffereredReader.readLine())!=null){
stringBuilder.append(JSON_String+"\n");
}
buffereredReader.close();
inputSteam.close();
httpURLConnection.disconnect();
return stringBuilder.toString().trim();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onProgressUpdate(Void... values) {
super.onProgressUpdate(values);
}
#Override
protected void onPostExecute(String result) {
TextView textView = (TextView)findViewById(R.id.fragment1_textview_JSONAPPEAR);
textView.setText(result);
JSON_String = result;
}
}
Here is the code for my Test.java
public class Test extends AppCompatActivity {
String JSON_String;
JSONObject jsonObject;
JSONArray jsonArray;
DataAdapter dataAdapter;
ListView listView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

int count = 0;
String jobid,problem,resolution;
while(count<jsonObject.length()){

}
} catch (JSONException e) {

}
Here is the code for my DataAdapter:
public class DataAdapter extends ArrayAdapter{

public DataAdapter(Context context, int resource) {
super(context, resource);
}
public void add(Data object) {

}
#Override

}
#Override
public Object getItem(int position) {

}
#Override

row = convertView;
DataHolder dataHolder;
if(row == null){

dataHolder.tx_jobid = (TextView) row.findViewById(R.id.tx_jobid);
dataHolder.tx_problem = (TextView) row.findViewById(R.id.tx_problem);
dataHolder.tx_resolution = (TextView) row.findViewById(R.id.tx_resolution);

}
Data data = (Data)this.getItem(position);
dataHolder.tx_jobid.setText(data.getJobid());
dataHolder.tx_problem.setText(data.getProblem());
dataHolder.tx_resolution.setText(data.getResolution());
return row;
}
static class DataHolder{
TextView tx_jobid,tx_problem,tx_resolution;
}
}
and here is what it displays when clicking on "Parse JSON" button.
listView empty after population
Any help or advise on why its not displaying would be much appreciated!
Thanks in advance!
your problem seems to be here :
while(count<jsonObject.length()){
you're not looping using the number of array elements but using the number of mapped key:value object which is one (the "server_response") , you have to change this line to :
while(count<jsonArray.length()){
,
you have just the first element showing because jsonObject.length() will return 1 since it have just one element.
from the doc, JSONObject, length() method:
Returns the number of name/value mappings in this object.
and in your case you have just one name/value mapped ("server_response":[array items...])
Check in Test.java. I think You are setting the adapter to the listview before adding data to it
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test_layout);
listView = (ListView)findViewById(R.id.test_listView);
dataAdapter = new DataAdapter(this, R.layout.row_layout);
JSON_String = getIntent().getExtras().getString("JSON_Data");
try {
jsonObject = new JSONObject(JSON_String);
jsonArray = jsonObject.getJSONArray("server_response");
int count = 0;
String jobid,problem,resolution;
while(count<jsonObject.length()){
JSONObject JO = jsonArray.getJSONObject(count);
jobid = JO.getString("jobid");
problem = JO.getString("problem");
resolution = JO.getString("resolution");
Data data = new Data(jobid,problem,resolution);
dataAdapter.add(data);
count++;
}
} catch (JSONException e) {
e.printStackTrace();
}
listView.setAdapter(dataAdapter); //change effected
}

The few lines doing the sending should be inside the for loop:
for (int i = 0; i < productlist.size(); i++) {
productid[i]=productlist.get(i).getProductid();
productquantity[i]=productlist.get(i).getProductquantity();
product_qty=productquantity[i];
product_id=productid[i];
String placeorderquerystring = "?address=" + address + "&product_id=" + product_id+"&product_qty="product_qty;
Log.d("Request : ", "starting 00 " + CC14.GETURL23 + placeorderquerystring);
new GetPlaceOrder(Order_From_App_All_new.this, CC14.GETURL23 + placeorderquerystring).execute();
}
You need to send the cart items as an JSON obj or array to server,
{
"Customer":"Name",
"cart":"Cart ID",
"date":"10-06-2016",
"time":"3.36",
"cartItems":[
{
"ProductID":"1",
"ProductQuantity":"3"
},
{
"ProductID":"2",
"ProductQuantity":"5"
},
{
"ProductID":"6",
"ProductQuantity":"4"
}
]
}
To get the above format, use the following code
private String getItems() {
JSONObject dataObj = new JSONObject();
try {
dataObj.putOpt("Customer", "Name");
dataObj.putOpt("cart", "Cart ID");
dataObj.putOpt("date", "DATE");
dataObj.putOpt("time", "TIME");
JSONArray cartItemsArray = new JSONArray();
JSONObject cartItemsObjedct;
for (int i = 0; i < cartItems.size(); i++) {
cartItemsObjedct = new JSONObject();
cartItemsObjedct.putOpt("ProductID", cartItems.get(i).getId);
cartItemsObjedct.putOpt("ProductQuantity", cartItems.get(i).getProductQuantity);
cartItemsArray.put(cartItemsObjedct);
}
dataObj.put("cartItems", cartItemsArray);
} catch (JSONException e) { // TODO Auto-generated catch bloc
e.printStackTrace();
}
return dataObj.toString();
}
