How to update all the Checkbox unchecked in dynamically created view using Button click?

public class CheckBoxActivity extends Activity {

    LinearLayout lay,lay1;
    ArrayList<String> list,list1;
    boolean[] checkBoxstate;
    List<Boolean> isCheckList;
    int j=0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.content_check_box);

        lay=(LinearLayout)findViewById(R.id.lay);

        list=new ArrayList<String>();
        list.add("1");
        list.add("1");
        list.add("2");
        list.add("2");
        list.add("3");
        list.add("4");
        list.add("4");
        list.add("4");

        list1=new ArrayList<String>();
        list1.addAll(list);

        Set<String> hs = new HashSet<>();
        hs.addAll(list);
        list.clear();
        list.addAll(hs);

        System.out.println("size" + list1.size());

        isCheckList = new ArrayList<Boolean>();
        Collections.fill(isCheckList, Boolean.FALSE);
        for (int m = 0; m < list1.size(); m++) {
            isCheckList.add(Boolean.FALSE);
        }

I have the following sample code for dynamically created checkbox. Once if I click the Button click, the checkbox is not checked. But the textview is changed. I am unable to check all the checkbox checked in the given view. I need some solution for this sample code.
