上下文语音命令 Google Glass

Question

我要做的是制作一个应该能够显示“ok, glass”命令以打开上下文语音命令的活动。 我已经实现了它，但只有当我点击活动的触摸板时。是否有可能当我说“好的，玻璃”-> 启动应用程序--> 然后它应该显示我的实时卡，然后出现“好的，玻璃”？

期待您的回答 问候

这是来自LiveCardDev Guide：

1. 表明您的 MenuActivity 支持上下文语音命令：

   // Initialize your LiveCard as usual.
   mLiveCard.setVoiceActionEnabled(true);
   mLiveCard.publish(LiveCard.PublishMode.REVEAL); // or SILENT
   

2. 修改您的 MenuActivity 以支持通过语音流调用：

   /**
    * Activity showing the options menu.
    */
   public class MenuActivity extends Activity {
   
       private boolean mFromLiveCardVoice;
       private boolean mIsFinishing;
   
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           mFromLiveCardVoice =
                   getIntent().getBooleanExtra(LiveCard.EXTRA_FROM_LIVECARD_VOICE, false);
           if (mFromLiveCardVoice) {
               // When activated by voice from a live card, enable voice commands. The     menu
               // will automatically "jump" ahead to the items (skipping the guard phrase
               // that was already said at the live card).
               getWindow().requestFeature(WindowUtils.FEATURE_VOICE_COMMANDS);
           }
       }
   
       @Override
       public void onAttachedToWindow() {
           super.onAttachedToWindow();
           if (!mFromLiveCardVoice) {
               openOptionsMenu();
           }
       }
   
       @Override
       public boolean onCreatePanelMenu(int featureId, Menu menu) {
           if (isMyMenu(featureId)) {
               getMenuInflater().inflate(R.menu.stopwatch, menu);
               return true;
           }
           return super.onCreatePanelMenu(featureId, menu);
       }
   
       @Override
       public boolean onPreparePanel(int featureId, View view, Menu menu) {
           if (isMyMenu(featureId)) {
               // Don't reopen menu once we are finishing. This is necessary
               // since voice menus reopen themselves while in focus.
               return !mIsFinishing;
           }
           return super.onPreparePanel(featureId, view, menu);
       }
   
       @Override
       public boolean onMenuItemSelected(int featureId, MenuItem item) {
           if (isMyMenu(featureId)) {
               // Handle item selection.
               switch (item.getItemId()) {
                   case R.id.stop_this:
                       stopService(new Intent(this, StopwatchService.class));
                       return true;
               }
           }
           return super.onMenuItemSelected(featureId, item);
       }
   
       @Override
       public void onPanelClosed(int featureId, Menu menu) {
           super.onPanelClosed(featureId, menu);
           if (isMyMenu(featureId)) {
               // When the menu panel closes, either an item is selected from the menu or the
               // menu is dismissed by swiping down. Either way, we end the activity.
               isFinishing = true;
               finish();
           }
       }
   
       /**
        * Returns {@code true} when the {@code featureId} belongs to the options menu or     voice
        * menu that are controlled by this menu activity.
        */
       private boolean isMyMenu(int featureId) {
           return featureId == Window.FEATURE_OPTIONS_PANEL ||
                  featureId == WindowUtils.FEATURE_VOICE_COMMANDS;
       }
   }
