How to search in custom list view

Hi, I have a custom list view, but I can’t correctly encode only the filter / search for a specific face name in CustomListView (basically I get it from JSON and stored in ArrayList) ... Please help me with this method filter in CustomListViewAdapter .java

Here is my Main_Activity.Java code

  array111.add(new AshTable(test1, test2, test3, test4, test5, test6, test7, test8, test9, test10, test11, test12, test13, test14, test15, test16, test17, test18, test19, test20, test21, test22, test23, test24, test25, test26, test27, test28, test29, test30, test31, test32, test33, test34, test35, test36, test37, test38, test39, test40, test41, test42));
            }


        } catch (JSONException e) {
            e.printStackTrace();
        }

        final CustomListViewAdapter adapter = new CustomListViewAdapter(getActivity(), R.layout.home_list_view, array111);
        lstv11.setAdapter(adapter);

        inputSearch.addTextChangedListener(new TextWatcher() {

            @Override
            public void afterTextChanged(Editable arg0) {
                // TODO Auto-generated method stub
                String text = inputSearch.getText().toString().toLowerCase(Locale.getDefault());
                adapter.filter(text);
            }

            @Override
            public void beforeTextChanged(CharSequence arg0, int arg1,
                                          int arg2, int arg3) {
                // TODO Auto-generated method stub
