Two radiobutton got selected in a groupbutton in Android Studio

I created an app using Android Studio and one of its activity contain questions and their choices using radiobuttons. I created those groupbuttons and radiobuttons programmatically, but the first question can choose two radio button when it shouldn't.
This is my code:
FeedbackFragment.java
try {
loading.setVisibility(View.GONE);
JSONObject jsonObject = new JSONObject(response);
if (!jsonObject.isNull("questions")) {
JSONArray questions = jsonObject.getJSONArray("questions");
LinearLayout.LayoutParams params;
for (int i = 0; i < questions.length(); i++) {
final JSONObject oneQuestion = questions.getJSONObject(i);
if (!oneQuestion.isNull("answers")) {
TextView textQuestion = new TextView(getActivity());
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
textQuestion.setLayoutParams(params);
textQuestion.setText(oneQuestion.getString("question_text"));
if(textQuestion.getParent() != null) {
((ViewGroup) textQuestion.getParent()).removeView(textQuestion);
}
layoutFeedback.addView(textQuestion);
groupChoice = new RadioGroup(getActivity());
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
params.setMargins(0,0,0,20);
groupChoice.setLayoutParams(params);
groupChoice.setId(Integer.valueOf(oneQuestion.getString("question_id")));
groupChoices.add(groupChoice);
if(groupChoice.getParent() != null) {
((ViewGroup) groupChoice.getParent()).removeView(groupChoice);
}
layoutFeedback.addView(groupChoice);
JSONArray choices = oneQuestion.getJSONArray("answers");
for(int j=0;j<choices.length();j++) {
JSONObject choice = choices.getJSONObject(j);
radioChoice = new RadioButton(getActivity());
radioChoice.setId(Integer.valueOf(choice.getString("answer_id")));
radioChoice.setText(choice.getString("answer_text"));
radioChoice.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
radioChoice.setButtonTintList(new ColorStateList(
new int[][]{
new int[]{-android.R.attr.state_enabled}, //disabled
new int[]{android.R.attr.state_enabled} //enabled
},
new int[] {
Color.BLACK //disabled
,getResources().getColor(R.color.colorPrimary) //enabled
}
));
groupChoice.addView(radioChoice);
}
LinearLayout borderBottom = new LinearLayout(getActivity());
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
1);
params.setMargins(0, 0, 0, 20);
borderBottom.setLayoutParams(params);
borderBottom.setBackgroundColor(Color.parseColor("#999999"));
borderBottom.setVerticalGravity(Gravity.BOTTOM);
layoutFeedback.addView(borderBottom);
}
}
}
} catch (JSONException e) {
e.printStackTrace();
Toast.makeText(getActivity(), "Error JSON Exception! " + e.toString(), Toast.LENGTH_SHORT).show();
loading.setVisibility(View.GONE);
}
The weird thing is, it only happened at first question, the other question worked fine. What went wrong? Please help.

how to put the heading after the header() in android

hi in the below I am fetching the data from database and getting the json response and displaying in an android table layout.But everything was working fine but i want to put some sub headings for displaying data for that I took the textview In that using setText() I am giving sub heading.But it's not displaying proper heading.
this output when I am running my app:
General registration
SI Date Toatal Registration
1 2015-04-01 2
2 2015-04-02 3
1 2015-04-02 3
Expected output:
SI Date Toatal Registration
General registration
1 2015-04-01 2
2 2015-04-02 3
Ipd registration
1 2015-04-02 3

Dynamic Android Table

I ran into another problem. Found a tutorial on how to create a dynamic table,followed it but mine doesnt seems to work,when adding the dynamic rows. The static column headings works fine.

i get this error in my eclipse "The constructor TableRow(new AsyncHttpResponseHandler(){}) is undefined". Please guide me.

TableRow requires context as an input param
But, when inside
AsyncHttpClient getleaders = new AsyncHttpClient();
getleaders.get("http://10.0.2.2/fanaticmobile/leaders.php", new AsyncHttpResponseHandler(){
......
}
the current this means object of AsyncHttpResponseHandler.. since you created Anonymous Inner Class of AsyncHttpResponseHandler
try
TableRow tr = new TableRow(Leaders.this);
instead.
This also goes without saying all instance where context is required you have to pass yourActivity.this , in your case Leaders.this..

Change TableRow tr = new TableRow(this); to TableRow tr = new TableRow(Leaders.this); in your AsyncHttpResponseHandler

set onClick, getText, etc for created views

This is a logic based problem where I will need a small sample of code or an idea supplied for an answer.
I am creating a U.I. programmatically from a JSON response. This app will load in an unknown amount of questions and answers. I'm using loops and conditional statements to create the Views for the U.I. and I am using an AsyncTask for most of the heavy lifting.
Well the problem I can't seem to figure out is: How will I give an unknown amount of views unique id's so that I can use them.
I am providing all the fragment code so you know exactly whats going on:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
view = inflater.inflate(R.layout.fragment_assessment, container, false);
ab = getActivity().getActionBar();
infoList = new ArrayList<HashMap<String, String>>();
new Load().execute();
return view;
}
class Load extends AsyncTask<String, Void, String> {
private ProgressDialog pDialog;
JSONParser jParser = new JSONParser();

protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(getActivity());
pDialog.setMessage("Loading questions. Please wait...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
protected String doInBackground(String... args) {
// getting JSON string from URL
String componentName = (String) ab.getSelectedTab().getText();
companyName = model.getcName();
projectName = model.getpName();
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
nameValuePairs.add(new BasicNameValuePair("company", companyName));
nameValuePairs.add(new BasicNameValuePair("project", projectName));
nameValuePairs.add(new BasicNameValuePair("component",
componentName));
JSONObject json = jParser.makeHttpRequest(url, "POST",
nameValuePairs);
// Check your log cat for JSON response
Log.d("All Questions: ", json.toString());
try {
// Checking for SUCCESS TAG
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
Log.v("RESPONSE", "Success!");
// products found: getting Array of Questions
questions = json.getJSONArray(TAG_QUESTIONS);
// looping through All Questions
for (int i = 0; i < questions.length(); i++) {
JSONObject c = questions.getJSONObject(i);
// Storing each JSON item in variable

I probably went about this the wrong way to begin with, however this is where I'm at. I will need to give the EditText an id to grab user input, I will need to give the ImageButton and id so it can perform events with the onClick function, and so on and so forth. You get the point I'm sure. So how would one of you tackle this problem?

It's really hard to answer this question. It really depends on what you want to do with the captured data. In any case, you don't have to generated IDs for the elements, you can set new event listeners using Anonymous classes. Then, each of these listeners can save your data to somewhere depending on your key (name?).
