Try this:

Inside your getView(…) method…

 final CheckBox lChk = ((CheckBox) pConvertView.findViewById(R.id.myChkBoxID)); 
 private List<lisInfo> m_lisInfo = new ArrayList<lisInfo>();

 lChk.setOnCheckedChangeListener(new OnCheckedChangeListener() {
     @Override
     public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
     // Populate the listInfo with check box status
     m_lisInfo.get(lPosition).setChkBoxStatus((isChecked));
  }
 });


 public class lisInfo{
   private boolean chkBoxStatus;

   public boolean isChkBoxStatus() {
        return chkBoxStatus;
    }

    public void setChkBoxStatus(boolean chkBoxStatus) {
        this.chkBoxStatus = chkBoxStatus;
    }
}

Now iterate the listInfo wherever required to get the check boxes statuses in the list view
