how to make input search for custom list view

Question

hello to every one i have a custom list view with a search and animation all works cool but in search i have a little problem . I would like to, for example, I search for a word in a sentence. But the way I used to enter the letters i have to put them in sequence. here is my code:

public class MainActivity extends Activity {
ListView list;
ListViewAdapter adapter;
EditText editsearch;
String[] country;
Typeface tf;
ArrayList<WorldPopulation> arraylist = new ArrayList<WorldPopulation>();

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.listview_main);
    editsearch = (EditText) findViewById(R.id.search);
    list = (ListView) findViewById(R.id.listview);
    tf = Typeface.createFromAsset(getAssets(), "fonts/BKOODB.TTF");

    country = new String[54];
    for (int x = 1; x < 54 + 1; x = x + 1) {
        String this_subject = "mo_" + String.valueOf(x);
        int resID = getResources().getIdentifier(this_subject, "string", getPackageName());
        country[x - 1] = getResources().getString(resID);
    }
    for (int i = 0; i < 54; i++) {
        WorldPopulation wp = new WorldPopulation(country[i]);
        // Binds all strings into an array
        arraylist.add(wp);
    }
    adapter = new ListViewAdapter(this, arraylist);
    list.setAdapter(adapter);
    editsearch.addTextChangedListener(new TextWatcher() {

        @Override
        public void afterTextChanged(Editable arg0) {
            // TODO Auto-generated method stub
            String text = editsearch.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
        }

        @Override
        public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
            // TODO Auto-generated method stub
        }
    });
    list.setOnScrollListener(new OnScrollListener() {

        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {
            hideKeyboard();

        }

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {

        }
    });
    new CountDownTimer(500, 500) {
        @Override
        public void onTick(long millisUntilFinished) {
        }

        @Override
        public void onFinish() {
            hideKeyboard();
        }
    }.start();
}

public class WorldPopulation {

}

Answer 1

try doing it in afterTextChanged Method because this allows you to enter all the text. and follow this link

    public void afterTextChanged(Editable s) {

    }

Answer 2

Try with custom adapter.

this will help you. Link
