Android programmatically disable autocomplete/autosuggest for EditText in emulator

Question

Targeting Android 2.2

I have read the answers to the following questions:

Turn off autosuggest for EditText?

Android: Multiline & No autosuggest

Answer 1

You could simply use the EditText's setThreshold() method. Set the threshold to let's say 100 when you don't want to show predictions. If you want to re-activate showing predictions, set it back to a small int like 1 or 2 depending on your needs.

Answer 2

The answer acceted as correct is faulty. To disable auto suggest add following property to your EditText XML

android:inputType="textFilter"

Answer 3

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<String> adapter = new ArrayAdapter<String>(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[] {""};
 }

Answer 4

I've tried all the above and none of above really helped me. I've search through available InputTypes and I've came up with a solution, which happened to be TYPE_TEXT_FLAG_AUTO_COMPLETE:

mEditText.setInputType(InputType.TYPE_TEXT_FLAG_AUTO_COMPLETE);

From its description:

This generally means that the input method should not be showing candidates itself, but can expect for the editor to supply its own completions/candidates from InputMethodSession.displayCompletions().

I haven't specified any completions set and as a result I'm not getting any auto-suggestions.

PS. Flag InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD mentioned in commend above does this trick as well, but it also disables toggling the language in the keyboard.

Answer 5

I was fighting with the same problem in the emulator. While testing, I realized that what was appearing wasn't the normal autocomplete, but a special Asian character preview (presumably because it requires multiple keys to generate one Asian character). So I solved this by setting the language to English. I think what I was seeing was the "Key Preview" option listed under the "Japanese IME" setting in "Language & keyboard".

I'm guessing that it would be pretty hard to disable this within an individual App without delving into the keyboard handling and language support.

Answer 6

You can also use following for disabling auto suggestion on any edittext.

<EditText>
android:inputType="textNoSuggestions|textVisiblePassword"
</EditText>

This worked for me.
