No items on ListControl

Question

I have a problem while displaying a list on Sony SmartWatch 2.

I copied layouts from sample project (AdvancedControlSample) and I have the following class:

 public class OpenPositionsView extends ControlExtension implements BaseView {
    private static final String LOG_TAG = "TAGG";

    private Context context;
    private ControlViewGroup mLayout;

    public OpenPositionsView(Context context, String hostAppPackageName) {
        super(context, hostAppPackageName);
        this.context = context;
        mLayout = setup();
    }

    public ControlViewGroup setup() {
        Log.i(LOG_TAG, "setup");

        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View layout = inflater.inflate(R.layout.watch_positions, null);
        ControlViewGroup mLayout = (ControlViewGroup) parseLayout(layout);

        return mLayout;
    }

    public void show(Controller parent) {

        int listCount = DataProvider.getInstance().getPositions().size();
        parent.sendListCountM(R.id.watch_positions_listview, listCount);
        parent.sendListPositionM(R.id.watch_positions_listview, 0);
        parent.refreshLayout(R.layout.watch_positions, null);


        Log.i(LOG_TAG, "show [listCount: " + listCount + "]");
    }

    @Override
    public void onRequestListItem(final int layoutReference, final int listItemPosition) {
        Log.d(LOG_TAG, "onRequestListItem [layoutReference: " + layoutReference + ", position: " + listItemPosition + "]");
        if (layoutReference != -1 && listItemPosition != -1 && layoutReference == R.id.watch_positions_listview) {
            ControlListItem item = createControlListItem(listItemPosition);
            if (item != null) {
                Log.d(LOG_TAG, "Sending list item");
                sendListItem(item);
            }
        }
    }

    @Override
    public void onListItemSelected(ControlListItem listItem) {
        super.onListItemSelected(listItem);
    }

    @Override
    public void onListItemClick(final ControlListItem listItem, final int clickType, final int itemLayoutReference) {
        Log.d(LOG_TAG, "onListItemClick [listItemPosition: " + listItem.listItemPosition + ", clickType: " + clickType + ", itemLayoutReference: "
                + itemLayoutReference + "]");
    }

    public void onClick(int id) {
        mLayout.onClick(id);
    }

    protected ControlListItem createControlListItem(int position) {
        Log.d(LOG_TAG, "createControlListItem [position: " + position + "]");

        ControlListItem item = new ControlListItem();
        item.layoutReference = R.id.watch_positions_listview;
        item.dataXmlLayout = R.layout.watch_positions_item;
        item.listItemPosition = position;

        // We use position as listItemId. Here we could use some other unique id
        // to reference the list data
        item.listItemId = position;

        Position target = DataProvider.getInstance().getPosition(position);

        if (target != null) {
            Bundle symbolBundle = new Bundle();
            symbolBundle.putInt(Control.Intents.EXTRA_LAYOUT_REFERENCE, R.id.watch_position_symbol);
            symbolBundle.putString(Control.Intents.EXTRA_TEXT, target.getSymbol());

            Bundle typeBundle = new Bundle();
            typeBundle.putInt(Control.Intents.EXTRA_LAYOUT_REFERENCE, R.id.watch_position_type);
            typeBundle.putString(Control.Intents.EXTRA_TEXT, target.getTypeAsString());

            item.layoutData = new Bundle[2];
            item.layoutData[0] = symbolBundle;
            item.layoutData[1] = typeBundle;
            Log.d(LOG_TAG, "Item list created: [symbolBundle: " + symbolBundle + ", typeBundle: " + typeBundle + "]");
        }

        return item;
    }

    protected Bundle[] createBundle(int position) {
        Bundle[] result = new Bundle[2];

        Position target = DataProvider.getInstance().getPosition(position);

        if (target != null) {
            Bundle symbolBundle = new Bundle();
            symbolBundle.putInt(Control.Intents.EXTRA_LAYOUT_REFERENCE, R.id.watch_position_symbol);
            symbolBundle.putString(Control.Intents.EXTRA_TEXT, target.getSymbol());

            Bundle typeBundle = new Bundle();
            typeBundle.putInt(Control.Intents.EXTRA_LAYOUT_REFERENCE, R.id.watch_position_type);
            typeBundle.putString(Control.Intents.EXTRA_TEXT, target.getTypeAsString());

            result[0] = symbolBundle;
            result[1] = typeBundle;
        }
        return result;
    }
}

However, onRequestListItem gets called and createControlListItem returns a correct item list. Touching the display gives me the following result:

onListItemClick [listItem: com.sonyericsson.extras.liveware.extension.util.control.ControlListItem@423b6960, clickType: 0, itemLayoutReference: -1]

The problem is, I do not see any of "added" list items :(

Make sure you also copied the List-related intents from the Manifest.xml:

<action android:name="com.sonyericsson.extras.aef.control.LIST_REFERESH_REQUEST" />
<action android:name="com.sonyericsson.extras.aef.control.LIST_REQUEST_ITEM" />
<action android:name="com.sonyericsson.extras.aef.control.LIST_ITEM_CLICK" />
<action android:name="com.sonyericsson.extras.aef.control.LIST_ITEM_SELECTED" />

Couple questions for you:

What is being shown on the screen? Is it just blank?
Are you calling showLayout() and sendListCount()? I don't see them in the above code. In the sample code in onResume() you should see something like:

showLayout(R.layout.layout_test_list, null); sendListCount(R.id.listView, mListContent.length);

These need to be called.
Did you make sure that sendListItem(item) is actually being called?

Ad. 1. It is not blank, it displays the top bar like in the example, but no elements are visible on the list. Ad. 2 & 3. Yes, I do call them. I verified it in the debugger. I even noticed that I cannot change packet names from the samples. After changing com.sonymobile.smartconnect.extension.advancedcontrolsample to com.myapp the application compiles, but when I tap the icon on the watch, nothing happens. I also changed it in manifest, of course. – oskario Nov 21 '13 at 08:55

Aren't you adding black text items to layout with black background? :) Please check your layouts.
