使用AsyncTask进行ANDROID自动完成

Question

I have an AutoCompleteTextView in my layout and I want to do an API call which takes the first character entered as a parameter. I do this API call in an AsyncTask to which I pass the first character as a parameter.

What listener should I use on AutoCompleteTextView so that AsyncTask call happens right after the first character is inputted ?

Answer 2

Fixed this issue using addTextChangedListener.

@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
            if (s.toString().trim().length() == 1) {
                isFileReceived = false;
                mAirport = new AsyncTaskAirport(s.toString());
                mAirport.execute((Void) null);
            }
