Google Glass Voice Recognition

Question

What I tried to do:

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

ArrayList<String> voiceResults = getIntent().getExtras()
.getStringArrayList(RecognizerIntent.EXTRA_RESULTS);

Card ShowDataCard = new Card(this);
ShowDataCard.setText(voiceResults);
View ShowDataCardView = ShowDataCard.toView();
setContentView(ShowDataCardView);
}

Failed work-around:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    String voiceResults = getIntent().getExtras()
            .getString(RecognizerIntent.EXTRA_RESULTS);

    Card ShowDataCard = new Card(this);
    ShowDataCard.setText(voiceResults);
    View ShowDataCardView = ShowDataCard.toView();
    setContentView(ShowDataCardView);
}

The String voiceResults is a failed workaround to the fact I cannot .setText to an arraylist string

Actual voice recognition code:

ArrayList<String> voiceResults = getIntent().getExtras()
    .getStringArrayList(RecognizerIntent.EXTRA_RESULTS);

Basically I am trying to save this voice recognition (going to use SharedPreferences) but for some reason it is an arraylist string and not just a string. Anybody know how to save it as a String? (or publish an activity with an arraylist string)

Since the results are an ArrayList of strings, you should check that the size() of the list is at least 1 and then call voiceResults.get(0) to get the string.
