messed up dynamic radio buttons in ArrayAdapter - android-layout

Question

when i run my app, i get much more radiobuttons than i need. It seems the radiobuttons repeat themselves in the same group. I don't really understand what is is going on. Here is my custom ArrayAdapter. I would like to know the problem here
public class QuestionsListAdapter extends ArrayAdapter<QuestionProperties> {
List<QuestionProperties> list;
Context test;
public QuestionsListAdapter(Context context, int resource, List<QuestionProperties> list2) {
super(context,resource,list2);
test = context;
list =list2;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view;
final RadioButton[] rB;
RadioHolder holder = new RadioHolder();
view= convertView;
LinearLayout.LayoutParams layoutParams = new RadioGroup.LayoutParams(
RadioGroup.LayoutParams.WRAP_CONTENT,
RadioGroup.LayoutParams.WRAP_CONTENT);
if(view == null)
{
LayoutInflater inflator = ((Activity) test).getLayoutInflater();
view = inflator.inflate(R.layout.question_list_row, null);
holder.questionTV = (TextView) view.findViewById(R.id.qTextView);
holder.radiogroup = (RadioGroup) view.findViewById(R.id.radio_group);
view.setTag(holder);
}
else{
//view = convertView;
holder = (RadioHolder) view.getTag();
}
holder.questionTV.setText(String.valueOf(list.get(position).getQuestionNo())+"."+" " + list.get(position).getQuestion());
rB=new RadioButton[list.get(position).possibleAns.length];
for(int count = 0; count<(list.get(position).possibleAns.length);count++)
{
rB[count]= new RadioButton(test);
rB[count].setId(count);
rB[count].setText(list.get(position).possibleAns[count]);
layoutParams.weight=1.0f;
layoutParams.setMargins(15, 0, 5, 10);
rB[count].setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
String a = String.valueOf(v.getId());
Toast.makeText(QActivity.context, "Radio Button "+ a,Toast.LENGTH_SHORT).show();
}
});
holder.radiogroup.addView(rB[count],layoutParams);
}
return view;
}
static class RadioHolder {
protected TextView questionTV;
protected RadioGroup radiogroup;
}

Answer 1

Finally after some hacks i solved it! i removed all the radio buttons in the else clause.
The solution..
public class QuestionsListAdapter extends ArrayAdapter<QuestionProperties> {
List<QuestionProperties> list;
RadioButton rB;
Context test;
RadioHolder holder;
String chkBtn;
LinearLayout.LayoutParams layoutParams = new RadioGroup.LayoutParams(
RadioGroup.LayoutParams.WRAP_CONTENT,
RadioGroup.LayoutParams.WRAP_CONTENT);
public QuestionsListAdapter(Context context, int resource, List<QuestionProperties> list2) {
super(context,resource,list2);
test = context;
list =list2;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view;
holder = new RadioHolder();
view= convertView;
Log.v("ConvertView", String.valueOf(position));
if(view == null)
{
LayoutInflater inflator = ((Activity) test).getLayoutInflater();
view = inflator.inflate(R.layout.question_list_row, parent,false);
holder.questionTV = (TextView) view.findViewById(R.id.qTextView);
holder.radiogroup = (RadioGroup) view.findViewById(R.id.radio_group);
//holder.radiogroup.check(list.get(position).getSelectedAns());
view.setTag(holder);
//((RadioHolder) view.getTag()).radiogroup.setTag(list.get(position));
Log.v("holder setTag", String.valueOf(position));
}
else{
view = convertView;
holder = (RadioHolder)view.getTag();
//((RadioHolder)view.getTag()).radiogroup.getTag();
holder.radiogroup.removeAllViews();
}
holder.questionTV.setText(String.valueOf(list.get(position).getQuestionNo())+"."+" " + list.get(position).getQuestion());
configureRadioButtons(position);
chkBtn = String.valueOf(list.get(position).getSelectedAns());
holder.radiogroup.check(Integer.valueOf(chkBtn));
return view;
}
static class RadioHolder {
protected TextView questionTV;
protected RadioGroup radiogroup;
}
public void configureRadioButtons(int pos){
final int position = pos;
//rB=new RadioButton(test);
for(int count = 0; count<(list.get(position).possibleAns.length);count++)
{
rB= new RadioButton(test);
rB.setId(count);
rB.setText(list.get(position).possibleAns[count]);
layoutParams.weight=1.0f;
layoutParams.setMargins(15, 0, 5, 10);
holder.radiogroup.addView(rB,layoutParams);
rB.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
String a = String.valueOf(v.getId());
list.get(position).setSelectedAns(v.getId());
chkBtn = String.valueOf(list.get(position).getSelectedAns());
Toast.makeText(QActivity.context, "Radio Button "+ a,Toast.LENGTH_SHORT).show();
}
});
rB.setOnCheckedChangeListener(new OnCheckedChangeListener(){
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
}
});
holder.radiogroup.clearCheck();
Log.v("rB added to radiogroup", String.valueOf(position));
}
}
