Android AutoCompleteTextbox

I am trying to implement a functionality like Twitter: when user type in '@', a dropdown menu shows-up with some suggestions.

Here's my current code:

mTextBox = (AutoCompleteTextView) findViewById(R.id.text);
String[] testArray = {"aaa", "aabc", "aaaa", "bbb" , "bcd", "zzz", "fff", "ndc"};

ArrayAdapter<String> adapter = 
            new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, testArray);

adapter.setNotifyOnChange(true);

mTextBox.setAdapter(adapter);

Currently, the behavior of the AutoCompleteTextView is, when I type in part of the word, the full suggestion shows up. For example, when I type in a, it shows nothing, when I type in aa, then it shows suggestion of aabc, aaa and aaaa.

How can I make it so when I type in @, it shows a list of all available options?

Thank you
