The aim of the application is to have spinners left (home team) and on the right (Away team). I can successfully populate the home team spinners but when i try to populate the away team spinners i get the error:
06-25 18:02:36.052: W/System.err(17916): org.json.JSONException: Value at 0 is null.
06-25 18:02:36.057: W/System.err(17916): at org.json.JSONArray.get(JSONArray.java:259)

06-25 18:02:36.057: W/System.err(17916): at app.league.npd.CaptainsInfo.useaJson(CaptainsInfo.java:309)
I can see that the error is coming from the "ateam" array, but i dont know what the problem is. I am new to android programming so any help would be appreciated.
Here is the code:

According to json.org (http://www.json.org/javadoc/org/json/JSONArray.html#getJSONObject(int)):
getJSONObject throws JSONException if there is no value for the index
or if the value is not a JSONObject.
How your ateam array is being populated? Seems that you are adding null values inside it. Make sure that your ateam array is populated only with initialized JSONObject, maybe the JSONObject is null when you add it to ateam array so you must check if is null before adding it to ateam.

I need to extract part of the string and display it in the spinner
I need that when the spinner display data example
For array entries like the following
"Equipo-001"
"Equipo-002"
Should show only:
"001"
"002"
Here's my code
private void rellenarSpinnerConFoliosDeMaquinasDelPunto(List<String> folios) {
maquinas = dbOn.getMaquinasDePunto(idPunto);
for (int i = 0; i < maquinas.size(); i++) {
foliosDeMaquinas.add(maquinas.get(i).getcFolioMaquina());
}
adaptadorFoliosMaquina = new ArrayAdapter<>(this, android.R.layout.simple_spinner_dropdown_item, folios);
adaptadorFoliosMaquina.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spn_folioMaquina.setAdapter(adaptadorFoliosMaquina);
spn_folioMaquina.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
ArrayList<String> numberFolios = new ArrayList<>();
for(int j =0; j < folios.size(); j++){
numberFolios.add(folios.get(j).substring(8, 10));
}
adaptadorFoliosMaquina = new ArrayAdapter<>(this, android.R.layout.simple_spinner_dropdown_item, numberFolios);
Check link for better reference on how to use substring.
You can use SPLIT function
ArrayList<String> data = new ArrayList();
foreach(String get:folios){
data.add(folios.split("-")[1]);
}
adapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_dropdown_item, data);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
If your result will be dynamic(The string length would vary in future) the below solution may work,
private void rellenarSpinnerConFoliosDeMaquinasDelPunto(List<String> folios) {
try{
maquinas = dbOn.getMaquinasDePunto(idPunto);
for (int i = 0; i < maquinas.size(); i++) {
foliosDeMaquinas.add(maquinas.get(i).getcFolioMaquina().toString().split("-")[1]);
}
} catch(ArrayIndexOutOfBoundsException e){
e.printStackTrace();
}
adaptadorFoliosMaquina = new ArrayAdapter<>(this, android.R.layout.simple_spinner_dropdown_item, folios);
adaptadorFoliosMaquina.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

This is my jsom

Please suggest me something.
Store your values in HashMap. cityname as Key and ID as value.
HashMap<String,String> spinnerValuesMap = new HashMap<String,String>();
for (int j=0; j<jsonArray.length(); j++){
JSONObject jobj = gg.getJSONObject(j);
String cityid = jobj.optString("id");
String cityName = jobj.optString("name")
spinnerValuesMap.put(cityName,cityid);
}
Access Id Like This:
String selectedItem= mySpinner.getSelectedItem().toString();
String cityId = spinnerValuesMap.get(selectedItem); // Your CIty id is here
I want to generate Spinners dynamically. Maximum numbers of Spinners I want to generate is 7. But I want to generate Spinners according to the data sets I'm getting from json response.
For the moment I have below shown code, which is used to identify how many spinners to generate. According to the below code MealDealCatCode contains L1, L2. So I want to get the value as 2 and display only 2 Spinners out of 7 (Hide remaining 5 Spinners).
How is possible to achieve my task. Any help will be appreciated.

I'm using two Spinners to show the items I'm getting from the json response. I have 2 problems right now. When u check my logcat u can see there are items repeating (Right side list, u can see so many pan). I want to have 1 item only once in my Spinner. I want to use something similar to distinct we use in sql databases.
My second problem is,
Select pan in the 1 spinner then 2nd spinner should contain items related to pan. (select pan in 1st spinner and 2nd should display only Pan large, pan medium and personal pan)

Output of this
Call this method to get distinct descriptions and then set the adapter using the return value of this function...
public static ArrayList<String> removeDuplicatesFromList(ArrayList<String> descriptions)
{
ArrayList<String> tempList = new ArrayList<String>();
for(String desc : descriptions)
{
if(!tempList.contains(desc))
{
tempList.add(desc);
}
}
descriptions = tempList;
tempList = null;
return descriptions;
}
For instance
description = Utils.removeDuplicatesFromList(description);
ArrayAdapter<String> dataAdapterDes = new ArrayAdapter<String>(
this, android.R.layout.simple_spinner_item, description);
NOTE:
I would suggest you make a new class call it Utils.java and place the above method inside it and then call it i have mentioned above.
Like this...
import java.util.ArrayList;
public class Utils
{
private Utils()
{
//Its constructor should not exist.Hence this.
}
public static ArrayList<String> removeDuplicatesFromList(ArrayList<String> descriptions)
{
ArrayList<String> tempList = new ArrayList<String>();
for(String desc : descriptions)
{
if(!tempList.contains(desc))
{
tempList.add(desc);
}
}
descriptions = tempList;
tempList = null;
return descriptions;
}
}
I hope it helps.
