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 do I sort the buttons generated from the following code alphabetically base on string values

<string name="Manuf0">best</string>
<string name="Manuf1">Bravo</string>
<string name="Manuf2">zoo</string>
<string name="Manuf3">Skitz</string>
<string name="Manuf4">don</string>
<string name="Manuf5">animal</string>
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
scrollviewManuf = new ScrollView(this);
LinearLayout linearlayout = new LinearLayout(this);
linearlayout.setOrientation(LinearLayout.VERTICAL);
scrollviewManuf.addView(linearlayout);
for (int i = 0; i < 5; i++)
{
LinearLayout linearManuf = new LinearLayout(this);
linearManuf.setOrientation(LinearLayout.HORIZONTAL);
linearlayout.addView(linearManuf);
Manufb = new Button(this);
int id = getResources().getIdentifier("Manuf" + i, "string", getPackageName());
String Manuf = getResources().getString(id);
Manufb.setText(Manuf);
Manufb.setId(i);
Manufb.setTextSize(30);
Manufb.setPadding(0, 0, 0, 0);
// b.setTypeface(Typeface.SERIF,Typeface.ITALIC);
Manufb.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
linearManuf.addView(Manufb);
Manufb.setOnClickListener(new View.OnClickListener() {

How do I sort the buttons generated from the following code alphabetically base on string values.
Currently they are listed as the buttons are produced 0 through to 5.
The list is in an xml string file, want to eb alphabetical so I can just add more to the file as needs be, and the programming just sort it alphabetically which suits me.
Not been able to find anything yet , but I am gueesing I may need to define the list in the file and sort that list can anyone point me in the right direction please.
Okay, so I can see the code is doing something but the sort order isn't changing and the String s is showing up in intellij as not used, : new code below:-
marked the sections with // here
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ArrayList<String> theStrings = new ArrayList<>();//Here
scrollviewManuf = new ScrollView(this);
LinearLayout linearlayout = new LinearLayout(this);
linearlayout.setOrientation(LinearLayout.VERTICAL);
scrollviewManuf.addView(linearlayout);
for (int i = 0; i < 28; i++) {
LinearLayout linearManuf = new LinearLayout(this);
linearManuf.setOrientation(LinearLayout.HORIZONTAL);
linearlayout.addView(linearManuf);
Manufb = new Button(this);
int id = getResources().getIdentifier("Manuf" + i, "string", getPackageName());
String Manuf = getResources().getString(id);
theStrings.add(Manuf); /// Here
Manufb.setText(Manuf);
Manufb.setId(i);
Manufb.setTextSize(30);
Manufb.setPadding(0, 0, 0, 0);
// b.setTypeface(Typeface.SERIF,Typeface.ITALIC);
Manufb.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
linearManuf.addView(Manufb);
Manufb.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String PManuf =Manuf;
// TODO Auto-generated method stub
String SManuf= Manuf.replaceAll("&","").replaceAll(" ","").replaceAll("/","").replaceAll(" / ","").replaceAll("/ ","").replaceAll(" /","".replaceAll("&",""));
//Panel= getResources().getString(id);
Toast.makeText(getApplicationContext(), Manuf+" Selected" , Toast.LENGTH_SHORT).show();
Intent passIntent = new Intent(Manufacturers.this,panels.class);
passIntent.putExtra("SManuf",SManuf);
passIntent.putExtra("PManuf",PManuf);
startActivity(passIntent);
}
} );
} Collections.sort(theStrings); //here
for (String s : theStrings) { //here
//...
this.setContentView(scrollviewManuf); }//here
}
}
The following code is looping each time it loops its adding an extra repeated option.
ie. Cat,dog,mouse, donkey correct list is the list but I am getting, Cat, dog.dog, mouse,mouse,mouse, donkey, donkey, donkey,donkey but still no sorting, still working on it but here is the code.
ArrayList<String> theStrings = new ArrayList<>();
for (int i = 0; i < 28; i++) {
int id = getResources().getIdentifier("Manuf" + i, "string", getPackageName());
String Manuf = getResources().getString(id);
theStrings.add(Manuf);
Collections.sort(theStrings);
for (String s : theStrings) {
LinearLayout linearManuf = new LinearLayout(this);
linearManuf.setOrientation(LinearLayout.HORIZONTAL);
linearlayout.addView(linearManuf);
Manufb = new Button(this);
Manufb.setText(Manuf);
Manufb.setId(i);
Manufb.setTextSize(30);
Manufb.setPadding(0, 0, 0, 0);
// b.setTypeface(Typeface.SERIF,Typeface.ITALIC);
Manufb.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
linearManuf.addView(Manufb);
Manufb.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String PManuf = Manuf;
// TODO Auto-generated method stub
String SManuf = Manuf.replaceAll("&", "").replaceAll(" ", "").replaceAll("/", "").replaceAll(" / ", "").replaceAll("/ ", "").replaceAll(" /", "".replaceAll("&", ""));
//Panel= getResources().getString(id);
Toast.makeText(getApplicationContext(), Manuf + " Selected", Toast.LENGTH_SHORT).show();
Intent passIntent = new Intent(Manufacturers.this, panels.class);
passIntent.putExtra("SManuf", SManuf);
passIntent.putExtra("PManuf", PManuf);
startActivity(passIntent);
}
});
}
}
this.setContentView(scrollviewManuf);
}
}

Read it into a list, sort it and loop over it:
ArrayList<String> theStrings = new ArrayList<>();
for (int i = 0; i < 28; i++) {
int id = getResources().getIdentifier("Manuf" + i, "string", getPackageName());
String Manuf = getResources().getString(id);
theStrings.add(Manuf);
}
Collections.sort(theStrings);
for (String s : theStrings) {
LinearLayout linearManuf = new LinearLayout(this);
linearManuf.setOrientation(LinearLayout.HORIZONTAL);
linearlayout.addView(linearManuf);
Manufb = new Button(this);
Manufb.setText(s); // <-- use the String here
Manufb.setId(i);
Manufb.setTextSize(30);
Manufb.setPadding(0, 0, 0, 0);
// b.setTypeface(Typeface.SERIF,Typeface.ITALIC);
Manufb.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
linearManuf.addView(Manufb);

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);
}
}
}
}
}

android_dynamically adding rows, how to get which row is clicked?

So I am dynamically adding rows to table which consist of some data (httpresponse) and buttons (like delete). How can I add onClickListener for delete button so it knows which row I want to delete?
This is part of my code, if you need more let me know:
try {
HttpResponse httpResponse = httpclient.execute(request);
String result = EntityUtils.toString(httpResponse.getEntity());
if (!result.isEmpty()) {
JSONArray ja = new JSONArray(result);
for (int i = 0; i < ja.length(); i++) {
JSONObject jsonObjekt = ja.getJSONObject(i);
Racuni novi = new Racuni();
novi.setCode(jsonObjekt.getString("Code"));
novi.setDate(jsonObjekt.getString("Date"));
novi.setTotal(jsonObjekt.getString("Total"));
niz.add(i, novi);
}
for (int i = 0; i < niz.size(); i++) {
TableRow redak = new TableRow(getApplicationContext());
final TextView code = new TextView(getApplicationContext());
code.setText(niz.get(i).getCode());
code.setPadding(0, 0, 5, 0);
TextView date = new TextView(getApplicationContext());
date.setText(niz.get(i).getDate());
date.setPadding(0, 0, 5, 0);
TextView total = new TextView(getApplicationContext());
total.setText(niz.get(i).getTotal());
total.setPadding(0, 0, 5, 0);
final Button print = new Button(getApplicationContext());
print.setText("P");
final Button delete = new Button(getApplicationContext());
delete.setText("D");
delete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//so this is what i would like it to do, but with the proper id
int id = Integer.parseInt(code.getText().toString());
HttpClient httpclient = new DefaultHttpClient();
HttpGet request = new HttpGet("http://staging-api.e-poslovanje.hr/ReceiptCash/Delete" + "?id=" + id);
request.addHeader("Authorization", "Basic " + base64EncodedCredentials);
try {
httpclient.execute(request);
Toast.makeText(getApplicationContext(), "You have deleted receipt " + code.getText().toString(), 5000).show();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
redak.addView(code);
redak.addView(date);
redak.addView(total);
redak.addView(delete);
redak.addView(print);
list.addView(redak);
}

You can use Tag to hold the Id.
On the delete button , set the Id as tag
tag. delete.setTag(code.getText().toString())
and on onClick() you can retrieve the id like..
int = delete.getTag();

Create a "Row" class with Buttons and Textview. Instead of creating each button in the for loop just create a row
class Row{
Button delete
Button print
Textview date
public Row(){
delete.setOnClickListener(.....);
}
}
and than in mainActivity
for (int i = 0; i < niz.size(); i++) {
Row row=new Row();
}

Display the array in android

How to get an array items like this
["String1", "string2", "string3",.....,"Stringn"]
but if we use Arrays.toString(array) it will display like [string1, string2, string3] but i want like above.
Thnaks in advance

This is how I did it:
private void btn3() {
LinearLayout layout = (LinearLayout) findViewById(R.id.ll);
layout.removeAllViewsInLayout();
layout.setPadding(15, 15, 15, 15);
tv2 = new TextView[list.size()];
for (int i = 0; i < list.size(); i++) {
tv2[i] = (TextView) new TextView(Random.this);
}
LayoutParams lparams = new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
for (int i = 0; i < list.size(); i++) {
tv2[i].setLayoutParams(lparams);
tv2[i].setText((i + 1) + " " + list.get(i));
layout.addView(tv2[i]);
}
}
