Answer 1

I was making project for my collage attendence and i had faced same trouble as you , I solved these problem by just putting these code in my activity code is :-

upload.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
          int child=listView.getChildCount();
          for(int i=0;i<child;i++) {
             View rgg=listView.getChildAt(i);

             radioGroup = (RadioGroup) rgg.findViewById(R.id.radio);

             int selectedId=radioGroup.getCheckedRadioButtonId();

             radioButton = (RadioButton) rgg.findViewById(selectedId);

}
            }
        });

Problem solved just changing in adapter class.

 package com.cfms.ApplicationLayer;

    import android.content.Context;
    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.view.ViewGroup;
    import android.widget.BaseAdapter;
    import android.widget.LinearLayout.LayoutParams;
    import android.widget.ListView;
    import android.widget.RadioButton;
    import android.widget.RadioGroup;
    import android.widget.RadioGroup.OnCheckedChangeListener;
    import android.widget.TextView;

    import com.cfms.cfms_project.R;

    public class RadioGroupAdapter extends BaseAdapter implements OnClickListener{

            private Context mContext;
            //TextView pretext;
            private int selected = -1;
            int countPre,countAbs,countHD;
            public RadioGroupAdapter(Context c){
                mContext = c;

            }

            public int getCount(){
              return mThumbIds.length;
            }

            public Object getItem(int position){ 
               return null;
            }

            public long getItemId(int position){
               return 0;
            }

            public View getView(int position, View convertView, ViewGroup parent){

                ViewHolder holder = null; 


             if (convertView == null){
                 LayoutInflater infalInflater = (LayoutInflater) mContext.getSystemService(mContext.LAYOUT_INFLATER_SERVICE);
                 convertView= infalInflater.inflate(R.layout.employee_attendance_row, null);
                 holder = new ViewHolder();
                 holder.txt=(TextView)convertView.findViewById(R.id.txt_emp_attendance);
                 holder.radiogroup=(RadioGroup)convertView.findViewById(R.id.radio_attendance);
                 holder.pre=(RadioButton)convertView.findViewById(R.id.radio_present);
                 holder.abs=(RadioButton)convertView.findViewById(R.id.radio_absent);
                 holder.halfday=(RadioButton)convertView.findViewById(R.id.radio_half_day);
                //AttendanceAttandanceView.totalpre=(TextView).findViewById(R.id.txtv_total_pre);

                // System.out.println("index of radio.........."+radioId);

                 convertView.setTag(holder);

                }
                 else
                 {
                     holder = (ViewHolder) convertView.getTag();
                 }


             holder.radiogroup.setOnCheckedChangeListener(new  OnCheckedChangeListener() {



                @Override
                public void onCheckedChanged(RadioGroup group, int checkedId) {
                    // TODO Auto-generated method stub
                    View radioButton = group.findViewById(checkedId);
                     int radioId = group.indexOfChild(radioButton);



                    if(radioId == 0)
                    {
                        countPre++;
                        AttendanceAttandanceView.totalpre.setText(""+countPre);

                    }

                    else if(radioId == 1)
                    {
                        countAbs++;
                        AttendanceAttandanceView.totalabs.setText(""+countAbs);
                    }

                    else if(radioId == 2)
                    {
                        countHD++;
                        AttendanceAttandanceView.totalHalfday.setText(""+countHD);
                    }


                    //selected = radioId;
                    //notifyDataSetChanged();

                }
            });







            holder.txt.setText(mThumbIds[position]);
            holder.pre.setTag(position);
           // holder.pre.setChecked(position == selected);

            holder.abs.setTag(position);
            //holder.abs.setChecked(position == selected);

            holder.halfday.setTag(position);
           //holder.halfday.setChecked(position == selected);

            convertView.setLayoutParams(new ListView.LayoutParams(LayoutParams.MATCH_PARENT ,60));
            return convertView;


        }

        public static String[] mThumbIds = {"EMP1",
            "abcdef ghijklm nopqrstu vwxyz ABCDEFGH IJKLM",
            "EMP3",

Thanks guys for attention.

public void onRadioButtonClick(View v) {
    RadioButton rb = (RadioButton) v;
    Toast.makeText(getApplicationContext(),
    rb.getText(),Toast.LENGTH_SHORT).show();
    View Rg = (View) rb.getParent();
    View LLayout = (View) Rg.getParent();
    TextView txtLvId = (TextView) LLayout.findViewById(R.id.ins_itemid);
    String LvID = txtLvId.getText().toString();
    Toast.makeText(getApplicationContext(), LvID, Toast.LENGTH_LONG).show();
}
