Class VuzixBubbleDelegate

public class VuzixBubbleDelegate extends android.view.View.AccessibilityDelegate

A lightweight mechanism to place bubbles on the UI to identify speech phrases

This class is an alternative to using VuzixSpeechClient. It provides the ability to have a spoken phrase added to a help bubbble on the user interface. When the user speaks the associated phrase the system will act as though the user clicked that view on the screen. This implementation may be done fully in XML, or via this class.

This mechanism provides less control than if the VuzixSpeechClient were used, but is very easy to implement and debug, and should not negatively affect the software when running on other devices with no Vuzix speech engine.

Bubbles can be places in any of the 9 pre-defined location, or using a raw offset value

This is an example of customizing the bubble to be placed in the upper right corner:

    myButton.setAccessibilityDelegate(new VuzixBubbleDelegate(Alignment.ALIGN_TOP_END));
