Targeting Android 2.2
I have read the answers to the following questions:
Turn off autosuggest for EditText?
Android: Multiline & No autosuggest
You can use the class AutoCompleteTextView and set the adapter that contains nothing AutoCompleteTextView Class Reference
example
public class CountriesActivity extends Activity {
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.countries);
ArrayAdapter adapter = new ArrayAdapter(this,
android.R.layout.simple_dropdown_item_1line, COUNTRIES);
AutoCompleteTextView textView = (AutoCompleteTextView)
findViewById(R.id.countries_list);
textView.setAdapter(adapter);
}
private static final String[] COUNTRIES = new String[] {""};
}
