Customizing the watch face

We did not want to take this example too far, so in the interest of simplicity, we decided to provide a configurable watch face background color. Clicking on the gear icon from the watch face settings lets us pick the background color, as shown here:

The WatchFaceConfigActivity class

The WatchFaceConfigActivity class renders a simple color picker to determine the background color:

public class WatchFaceConfigActivity extends Activity implements WearableListView.ClickListener, WearableListView.OnScrollListener  
{ 
  @Override 
  protected void onCreate(Bundle savedInstanceState)  
  { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_digital_config); 
    mHeader = (TextView) findViewById(R.id.header); 
    WearableListView listView = (WearableListView) findViewById(R.id.color_picker); 
    BoxInsetLayout content = (BoxInsetLayout) findViewById(R.id.content); 
  } 
} 

Here's a screenshot of the watch face when we select a background...
