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.

Add view Programatically in LinearLayout:
layout.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/llParent"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
</LinearLayout>
Activity.java:
LinearLayout llParent = (LinearLayout)findViewById(R.id.llParent);
onPostExecute() of AsyncTask:
for (int i=0;i<Your_ArrayList.size(); i++){
TextView txtView = new TextView(this);
txtView.setText(Your_ArrayList.get(i).getMovieName());
llParent.addView(txtView);
}
Edit:
llParent.invalidate();
Hope this will help you.

inside your for loop
movie = new TextView(MainActivity.this);
movie.setTag(i);
insid your onPost() for loop
final int childCount = ll.getChildCount();
for (int y = 0; y < childCount; y++) {
final View child = ll.getChildAt(y);
if (child instanceof FrameLayout) {
int childs = ((FrameLayout) child).getChildCount();
for (int j = 0; j < childs; j++) {
final View childViews = ((ViewGroup) child)
.getChildAt(j);
if (childViews instanceof TextView) {
final Object tagObj = childViews.getTag();
if (tagObj != null && tagObj.equals(i)) {
((TextView) childViews).setText("Movie "
+ i);
}
}
}
}
}

Adding views programmatically. displays nothing

I am adding a view to my table row programmatically. Everything is working fine and logcat isn't showing any errors. Strangely enough nothing is being displayed in my activity.
Below is the code I am using:
try{
int k=0;
for(i=0;i<=Math.ceil(jArray.length()/2);i++){
Log.e("I...",""+i+" "+Math.ceil(jArray.length()/2));
tr_head = new TableRow(getApplicationContext());
tr_head.setId(10+i);
tr_head.setPadding(30, 30, 30, 5);
tr_head.setGravity(Gravity.LEFT|Gravity.CENTER_HORIZONTAL);
tr_head.setLayoutParams(new LayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT));
for(j=0;j<2;j++)
{
if (k<jArray.length()){
jobj1 = jArray.getJSONObject(k);
LinearLayout parent = new LinearLayout(getApplicationContext());
parent.setLayoutParams(new LinearLayout.LayoutParams(dpToPx(150), dpToPx(150)));
parent.setOrientation(LinearLayout.VERTICAL);
parent.setGravity(Gravity.CENTER);
ImageView img = new ImageView(getApplicationContext());
img.setLayoutParams(new LinearLayout.LayoutParams(dpToPx(60),dpToPx(60)));
Picasso.with(getApplicationContext()).load(jobj1.getString("image")).resize(50,50).into(img);
parent.addView(img);
TextView txt = new TextView(getApplicationContext());
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
txt.setLayoutParams(params);
txt.setText(jobj1.getString("name"));
parent.addView(txt);
tr_head.addView(parent);
parent.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
try{
String catid=jobj1.getString("category_id");
Intent intent = new Intent(getApplicationContext(), DescribeComplain.class);
intent.putExtra("category_id",catid);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK|Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
}
catch(JSONException je){
je.printStackTrace();
}
}
});
}
else{
break;
}
k++;
}
t1.addView(tr_head, new TableLayout.LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
}
}
catch(JSONException je){
je.printStackTrace();
}
}
});
}
catch(JSONException e){
Log.e("log_tag", "Error parsing data "+e.toString());
}

After trying loads of methods, I solved it by setting linearLayout's parameters like this
LinearLayout parent = new LinearLayout(SelectCaegory.this);
TableRow.LayoutParams Paramslinear = new TableRow.LayoutParams(dpToPx(150),dpToPx(150));

Your problem is with this line:
LinearLayout parent = new LinearLayout(getApplicationContext());
You are creating a new view but she's not attach to your root view.
Try to declare your LinearLayout on your layout file, and fint it with the ID
LinearLayout parent = (LinearLayout) findViewById(R.id.my_parent_layout);

how can i getText() From edittext programmatically created

i create two edittext programmatically and i need to get text from him
this is my code for create edittext
layoutParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
layoutParams.setMargins(10, 10, 10, 10);
//First EditText
edText = new EditText(getActivity());
edText.setId(0);
edText.setLayoutParams(new LinearLayout.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT,
1f));
edText.setBackgroundResource(R.drawable.edittext);
edText.setPadding(5, 5, 5, 5);
linear=(LinearLayout)rootView.findViewById(R.id.edittextpanel);
linear.addView(edText ,layoutParams);
nb++;
//Second EditText
edText = new EditText(getActivity());
edText.setId(1);
edText.setLayoutParams(new LinearLayout.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT,
1f));
edText.setPadding(5, 5, 5, 5);
edText.setBackgroundResource(R.drawable.edittext);
linear.addView(edText ,layoutParams);
Help please i'm blocked

edText = new EditText(getActivity());
edText.setId(id);
String stringAnswer = edText.getText().toString();
If you want to create and reference more than one edit text you'll have to create an EditText array
List<EditText> allEDs = new ArrayList<EditText>();
Then create the Edit Texts
edText = new EditText(getActivity());
edText.setId(id);
Push them into the array
allEDs.add(edText);
Create a string array same size as the EditText array
String[] ETResults = new String[allEDs.size()];
Loop through the EditText array and put converted results into String array
for(int i=0; i < allEDs.size(); i++){
ETResults[i] = allEDs.get(i).getText().toString();
}
And then assign the desired string to whatever you want
String stringAnswer = ETResults[i];

try {
final ViewGroup viewGroup = (ViewGroup) ((ViewGroup) context.findViewById(android.R.id.content)).getChildAt(0);
for(int i = 0; i <viewGroup.getChildCount(); i++){
if(viewGroup.getChildAt(i) instanceof EditText) {
EditText view = (EditText)viewGroup.getChildAt(i);
Log.i("val " , " val " + ((EditText) viewGroup.getChildAt(i)).getText() + " view "+ view.getText() );
}
}
}catch (Exception ex){
Log.e("Error in Bind layout", ex.toString());
}

Maintain a reference to both EditTexts. Put the following in the main body of your Fragment to make them globally accessible..
EditText edText1;
EditText edText2;
Then in the method you've shown you can use...
// Do some stuff
edText1 = new EditText(getActivity());
// Do some more stuff
edText2 = new EditText(getActivity());
...
Later when you need to get the text you can use...
String text1 = edText1.getText().toString();
String text2 = edText2.getText().toString();
Alternatively you can find them later in your Fragment using their ids...
LinearLayout linear = (LinearLayout) findViewById(R.id.edittextpanel);
EditText et = (EditText) linear.findViewById(0);
String text1 = et.getText().toString();
et = (EditText) linear.findViewById(1);
String text2 = et.getText().toString();

Dynamically add table row in table and display it in dialog box in android

I am able to create a dialog box and show a table in it, but i wanted to add some more rows to it dynamically.
These rows should have textviews in it (say 3 in a row).
Please direct me on this.
Thanks in advance
My code, which is not working, is as follows:
struct3x5 is layout file with table layout and table of 3x5 dimension
1). On click event code
button.setOnClickListener(new OnClickListener()
{
public void onClick(View arg0) {
final String NAMESPACE = "http://tempuri.org/";
final String METHOD_NAME = "method";
final String SOAP_ACTION = "http://tempuri.org/method";
final String URL = "http://xyz/pqr/webserv.asmx";
// custom dialog
final Dialog dialog = new Dialog(context,R.style.cust_dialog);
dialog.setContentView(R.layout.struct3x5);
dialog.setTitle("XYZ");
// set the custom dialog components - text, image and button
TextView text1 = (TextView) dialog.findViewById(R.id.textView1);
text1.setText("");
TextView text2 = (TextView) dialog.findViewById(R.id.textView2);
text2.setText("Vehicle(Rs in Lacs)");
TextView text3 = (TextView) dialog.findViewById(R.id.textView3);
text3.setText("TPP(Rs in Lacs)");
TextView text4 = (TextView) dialog.findViewById(R.id.textView4);
text4.setText("PL(Rs in Lacs)");
TextView text5 = (TextView) dialog.findViewById(R.id.textView5);
text5.setText("Insurance(Rs in Lacs)");
String [] data = {};
String x = " ";
int colsize = 5;
int rowcount =(data.length)/colsize;
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject response = (SoapObject)envelope.getResponse();
data = getarray(response);
}
catch (Exception e){
Toast.makeText(classname.this,"error",Toast.LENGTH_LONG).show();
}
createtable(data,rowcount);
dialog.show();
}
});
2). _Function to create table
private void createtable(String[] data, int rowcount) {
// TODO Auto-generated method stub
LinearLayout t1=(LinearLayout)findViewById(R.id.tableLayout3x5);
//TextView[] tva= new TextView[data.length];
int count =0;
for(int i=0;i<rowcount;i++)
{
TableRow tr=new TableRow(this);
tr.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
for(int j=0;j<(data.length/rowcount); j++)
{
TextView text = new TextView(this);
text.setText(data[count].toString());
text.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, Gravity.CENTER_HORIZONTAL));
tr.addView(text);
count++;
}
t1.addView(tr, new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
}
}

You can do something along these lines to dynamically add more rows:
LinearLayout table = (LinearLayout)findViewById(R.id.my_container);
TableRow text_row = new TableRow(this);
text_row.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
// create new text row for label
TextView text = new TextView(this);
text.setText("My Text");
text.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
text_row.addView(text);
table.addView(text_row, new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
