Question

I’ve been reading some topics about filtering a list-view, but i am getting confused because i only got o few knowledge on adapters and different kinds of it. i found a solution thats is almost similar to my problem. Here is the code posted by Zoleas

TextWatcher filterTextWatcher = new TextWatcher() {

        public void afterTextChanged(Editable s) {
        }

        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }

        public void onTextChanged(CharSequence s, int start, int before, int count) {
            _myAdapter.getFilter().filter(s);
        }
    };
    _filterText = (EditText) findViewById(R.id.search_box);
    _filterText.addTextChangedListener(filterTextWatcher);  

I am confused on how i can declare my adapter in the method Ontextchanged because my adapter looks like this.

setListAdapter(new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1, result));

Need help on how to implement the filter here is my full code on my listview.

protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.firstaid);
    filterText = (EditText) findViewById(R.id.acET);
        DbHelper tblFa = new DbHelper(this);
    tblFa.open();
    ArrayList<String> result = tblFa.getFAData();
    result = tblFa.getFAData();
    setListAdapter(new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1, result));
    ListView lv = getListView();
    lv.setTextFilterEnabled(true);
    tblFa.close();
    }

try that;

EditText edt = (EditText) this.view.findViewById(R.id.editTxtView);

        edt.addTextChangedListener(new TextWatcher() {
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
             ListView listView = (ListView) view.findViewById(R.id.yourListviewID);


                YourAdapterOrWhateverAdapter adapter = (YourAdapterOrWhateverAdapter) listView.getAdapter();  


               adapter.getFilter().filter(s);



        @Override
        public void afterTextChanged(Editable s) {

        }
