How to select multiple radio objects in a list and arrange in an arraylist using their positions
I have 25 questions, each with 4 options (only 4 radio buttons) to choose from among the four in the list. I am getting the selected position and their radio id exactly, but I cannot store my position with the radio id in the arraylist. And another problem is that the scrolling of the list is visible, the radio buttons are marked inappropriate. Please go below and help me.
Thank you Advance!
Here is my adapter class, please have a look at it.
public class CustomListAdapter extends BaseAdapter {
private Integer[] listData;
int selectedPosition = -1;
private LayoutInflater mInflater;
public CustomListAdapter(Context context, Integer[] listData) {
super();
this.listData = listData;
mInflater = LayoutInflater.from(context);
validdata = new ArrayList<String>();
int size = values.length;
Log.d("size", "" + size);
for (int i = 0; i < size; i++) {
checked.add(false);
validdata.add("");
checkeddata.add("");
}
}
@Override
public int getCount() {
return listData.length;
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
public View getView(final int position, View convertView,
ViewGroup parent) {
final ViewHolder holder;
View view = convertView;
if (view == null) {
view = mInflater.inflate(R.layout.items, null);
holder = new ViewHolder();
holder.headlineView = (TextView) view
.findViewById(R.id.textview1);
holder.r1 = (RadioButton) view.findViewById(R.id.radio0);

try this code, it works 1.i took one bean class with string and integer as fields, i create one arraylist with bean type 2.in onCreate i create objects and ask required question and add adapter code to list // here
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder mHolder;
// if (convertView == null) {
mHolder = new ViewHolder();
convertView = LayoutInflater.from(mContext).inflate(R.layout.listitems, null);
mHolder.mTextView = (TextView) convertView.findViewById(R.id.textView1);
mHolder.mGroup = (RadioGroup) convertView.findViewById(R.id.radioGroup1);
mHolder.mRedButton1 = (RadioButton) convertView.findViewById(R.id.radio0);
mHolder.mRedButton2 = (RadioButton) convertView.findViewById(R.id.radio1);
mHolder.mRedButton3 = (RadioButton) convertView.findViewById(R.id.radio2);
// convertView.setTag(mHolder);
// }
// else {
// mHolder = (ViewHolder) convertView.getTag();
// }
final MyQuestion mMyQuestion = myQuestions.get(position);
mHolder.mTextView.setText(mMyQuestion.getmQuestion());
int mQuestion_answed = mMyQuestion.getQuestion_answed();
mHolder.mGroup.setOnCheckedChangeListener(null);
if (mQuestion_answed != 0) {
switch (mQuestion_answed) {
case 1:
mHolder.mRedButton1.setChecked(true);
break;
case 2:
mHolder.mRedButton2.setChecked(true);
break;
case 3:
mHolder.mRedButton3.setChecked(true);
break;
default:
break;
}
}
// listener for radioGroup
mHolder.mGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
switch (checkedId) {
case R.id.radio0:
mMyQuestion.setQuestion_answed(1);
break;
case R.id.radio1:
mMyQuestion.setQuestion_answed(2);
break;
case R.id.radio2:
mMyQuestion.setQuestion_answed(3);
break;
default:
break;
}
}
});
return convertView;
}
// VIewHolder
private class ViewHolder {
TextView mTextView;
RadioGroup mGroup;
RadioButton mRedButton1, mRedButton2, mRedButton3;
}
// bean class
public class MyQuestion {
private String mQuestion;
private int question_answed;
public MyQuestion() {
super();
}
public String getmQuestion() {
return mQuestion;
}
public void setmQuestion(String mQuestion) {
this.mQuestion = mQuestion;
}
public int getQuestion_answed() {
return question_answed;
}
public void setQuestion_answed(int question_answed) {
this.question_answed = question_answed;
}
}
this is an ArrayList i am using
private ArrayList<MyQuestion> mQuestionsList = new ArrayList<MyQuestion>();
