I\'ve got to set an autocompletion for my application.

I\'ve already understood the AutoCompleteTextView operation, but I\'d like to dynamically modify the Stri

Can't comment on the answer selected as correct so here it goes. This solution will only work if you press a key after the specified delay has elapsed. If you write very fast and then stop no request will be sent to the server.

You can make that happen using a Handler and sending messages delayed:

public void onTextChanged(CharSequence s, int start, int before,
                           int count) {

    final String term = s.toString();
    if( term.length() > 3 ){
        autocompleteHandler.removeMessages(0);
        autocompleteHandler.postDelayed(new Runnable(){
            @Override
            public void run() {
            new SearchLocationAsyncTask(context, term).execute();
        }}, 350);
    }
}

Where SearchLocationAsynTask calls your server and updates the view accordingly.

Basically what this does is add a new message to the handler everytime the text changes, if there are any messages in the queue they get deleted and a new one is added to execute in 350ms.
