Android Development: How to Add an Auto Complete View

This tutorial shows you how to add a Country text field with an auto complete feature. Note, the default threshhold for autocomplete is 2, so you will need to enter two characters before autocomplete will recognize your input. You can download the below project.

1. AutoCompleteTextView is an implementation of the EditText widget that will provide auto-complete suggestions as the user types. The suggestions are extracted from a collection of strings.
2. Create a project
3. Open Main.xml and add an AutoCompleteTextView
4. Build project to update the R.java file
5. Add this code in OnCreate:


ArrayAdapter adapter = new ArrayAdapter(this,
android.R.layout.simple_dropdown_item_1line, COUNTRIES);
final AutoCompleteTextView autoCompleteTextView = (AutoCompleteTextView)
findViewById(R.id.AutoCompleteTextView01);
autoCompleteTextView.setAdapter(adapter);


6. Add this code after OnCreate():


static final String[] COUNTRIES = new String[] {
"Afghanistan", "Albania", "Algeria", "American Samoa", "Andorra",
"Angola", "Anguilla", "Antarctica", "Antigua and Barbuda", "Argentina",
"Armenia", "Aruba", "Australia", "Austria", "Azerbaijan",
