Я хочу показать элемент в AutoCompleteTextView. Работает нормально, и все выпадающие элементы отображаются. но в соответствии с моими потребностями я не хочу устанавливать элемент в поле автозаполнения при нажатии элемента. Как я могу достичь этого?
public class AutoCompleteViewActvitiy extends Activity {

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.support_simple_spinner_dropdown_item);
//after calling this service then you will get resposne ...in post method
new CallServiceForFetchResponseOfCategory().execute();
}

public static final String REQUEST_METHOD = "GET";
public static final int READ_TIMEOUT = 15000;

@Override
protected String doInBackground(String... params) {
String stringUrl = params[0];
String result;
String inputLine;
try {
URL myUrl = new URL(stringUrl);
HttpURLConnection connection = (HttpURLConnection)
myUrl.openConnection();
connection.setRequestMethod(REQUEST_METHOD);
connection.setReadTimeout(READ_TIMEOUT);

} catch (IOException e) {
e.printStackTrace();
result = null;
}
return result;
}

super.onPostExecute(result);
//in response you will get category array ....
//like
then you will set array into this :
language = .......;
then
setResponse();
}
}

autoCompleteTextView = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1);
autoCompleteTextView.setThreshold(1);//will start working from first character
