Is there any way to populate the custom "ok glass" menu in my glassware programmatically?
I have an application where the user will be in an immersion and interact with the system mainly by voice commands. The immersion consists of a CardScrollView displaying different sets of data. These sets are added and removed dynamically from a bluetooth service talking to a phone and the glass unit can't know in advance what new sets will appear.
What I want the user to be able to do is to list all current sets in the voice menu and from there choose which set to switch to. For example, if I at the moment have the sets A, B, C and D, I want the user to be able to say "ok glass, go to set", see a sub menu with A, B, C and D and then say for example "C" to switch to set C in the view.
Is this at all possible?
The glassware is going to run in a closed environment with no connection to MyGlass at all, so custom voice commands for the menu with the development permission is not a problem.
From what I understand you want you application to be already running when the user speaks. If this is correct then you can simply implement a custom menu with contextual voice commands. I believe you can always repopulate the menu just before it is being shown by overriding onPreparePanel.
I haven't tested it but guessing from the guide something like:
@Override
public boolean onPreparePanel(int featureId, View view, Menu menu) {
if (featureId == WindowUtils.FEATURE_VOICE_COMMANDS) {
menu.clear();
for (MyMenuItem item : mCurrentMenuItems) {
menu.add(Menu.NONE, item.getId(), Menu.NONE, item.getTitle());
}
}
return super.onPreparePanel(featureId, view, menu);
}
@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
if (featureId == WindowUtils.FEATURE_VOICE_COMMANDS) {
switch (item.getItemId()) {
case MENU_ITEM_A:
// do something
break;
default:
return true;
}
return true;
}
return super.onMenuItemSelected(featureId, item);
}
MyMenuItem would be a simple class which holds a unique id of an item and its title. mCurrentMenuItems is a list of items to be shown at the moment. You can change its content using a background service, for example.
