Search with multi selection listview with checkbox is not working

Listview with checkbox working properly with scroll but when I put text in searchview,everything in listview is filtered on the basis of text but selected checkboxes are not on correct place on filtering listview.

Please help me....

Thanks in advance.

In listview class listview is set here

       lv1.setAdapter(custom1);
       public boolean onQueryTextChange(String newText) {

    lv1.setVisibility(View.VISIBLE);

    if (TextUtils.isEmpty(newText)) {
       // lv1.clearTextFilter();
        custom1.getFilter().filter("");


    } else {
        // lv.setFilterText(newText.toString());
        custom1.getFilter().filter(newText);
        custom1.notifyDataSetChanged();
        //      getFilterableArrayAdapter().getFilter().filter(prefix);

    }
    return true;
    //adapter.getFilter().filter(newText);
    //showResults(newText + "*");
    //return true;
}

public boolean onQueryTextSubmit(String query) {
    //showResults(query + "*");
    return true;
}

public boolean onClose() {
    //showResults("");

    // lv.setAdapter(customAdapter);
    //  searchView.setQuery(query, true);
    return true;
}

Adapter for list is here
