Auto Complete

To create a text entry widget that provides auto-complete suggestions, use the AutoCompleteTextView widget. Suggestions are received from a collection of strings associated with the widget through an ArrayAdapter

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

    AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.autocomplete_country);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.list_item, COUNTRIES);
    textView.setAdapter(adapter);

setContentView(textView);}
