Question

我要做的是创建一个应该能够显示“ok，glass”命令来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控板时。有可能当我说“OK，glass” - ＆gt;启动应用程序 - ＆gt;然后它应该显示我的现场卡，然后出现“ok，glass”？

期待您的回答问候

这来自LiveCard Dev Guide：

表示您的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

修改您的MenuActivity以支持通过语音流程调用：

/**
 * 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;
    }
}
