Question

我正在尝试更新支持上下文语音命令的低频实时卡的经度和纬度（可以从XE 21.0更新中获得）。

由于我的服务呈现了实时卡并收听了位置更新，因此我不确定如何从服务本身添加上下文菜单。官方文档中的示例显示它们已添加到活动中。

这是我的代码，

public class Start_service extends Service {

    private static final String LIVE_CARD_TAG = "LiveCardDemo";
    public static double lati;
    public static double longi;
    public static float speed;
    private LiveCard mLiveCard;
    private RemoteViews mLiveCardView;
    private final Handler mHandler = new Handler();
    private final UpdateLiveCardRunnable mUpdateLiveCardRunnable =
        new UpdateLiveCardRunnable();
    private static final long DELAY_MILLIS = 3000;
    @Override
    public void onCreate() {
        super.onCreate();
        Criteria criteria = new Criteria();
        criteria.setAccuracy(Criteria.ACCURACY_FINE);
        LocationManager mLocationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
        String provider = mLocationManager.getBestProvider(criteria, true);
        boolean isEnabled = mLocationManager.isProviderEnabled(provider);
        if (isEnabled) {
        // Define a listener that responds to location updates
        LocationListener locationListener = new LocationListener() {
        @Override
        public void onLocationChanged(Location location) {
        // Called when a new location is found by the network location provider.
        if (location != null){
        Geocoder geocoder = new Geocoder(Start_service.this.getBaseContext(), Locale.getDefault());

        try {
            lati= location.getLatitude();
            longi=location.getLongitude();
            speed=location.getSpeed();
        }
        catch (IOException e) {
        System.out.println(e);
        e.printStackTrace();
        }
        }

    }
        }


        // Register the listener with the Location Manager to receive location updates
        mLocationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 1000, 0, locationListener);
        }
    }

这是我的渲染低频真人卡的代码，这也是上面的服务类，现在我该如何为它添加一个上下文语音菜单？

 @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        if (mLiveCard == null) {

            // Get an instance of a live card
            mLiveCard = new LiveCard(this, LIVE_CARD_TAG);

            // Inflate a layout into a remote view
            mLiveCardView = new RemoteViews(getPackageName(),
                R.layout.main_layout);
            // Set up the live card's action with a pending intent
            // to show a menu when tapped
            Intent menuIntent = new Intent(this, Sample.class);
            menuIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
                Intent.FLAG_ACTIVITY_CLEAR_TASK);
            mLiveCard.setAction(PendingIntent.getActivity(
                this, 0, menuIntent, 0));
            // Set up initial RemoteViews values        
            mLiveCardView.setTextViewText(R.id.latitude_value,
                    getString(R. id.latitude_value));
            mLiveCardView.setTextViewText(R.id.longitude_value,
                    getString(R.id.longitude_value));
            mLiveCardView.setTextViewText(R.id.speed_value,
                    getString(R.id.speed_value));
            // Publish the live card
            mLiveCard.setVoiceActionEnabled(true);
            mLiveCard.publish(PublishMode.REVEAL);

            // Queue the update text runnable
            mHandler.post(mUpdateLiveCardRunnable);
        }
        return START_STICKY;
    }

    @Override
    public void onDestroy() {
        if (mLiveCard != null && mLiveCard.isPublished()) {
          //Stop the handler from queuing more Runnable jobs
            mUpdateLiveCardRunnable.setStop(true);

            mLiveCard.unpublish();
            mLiveCard = null;
        }
       /// mlocManager.removeUpdates(mlocListener);
        super.onDestroy();
    }

    /**
     * Runnable that updates live card contents
     */
    private class UpdateLiveCardRunnable implements Runnable{

        private boolean mIsStopped = false;

        /*
         * Updates the card with a fake score every 30 seconds as a demonstration.
         * You also probably want to display something useful in your live card.
         *
         * If you are executing a long running task to get data to update a
         * live card(e.g, making a web call), do this in another thread or
         * AsyncTask.
         */
        public void run(){
            if(!isStopped()){


                mLiveCardView.setTextViewText(R.id.latitude_value,
                    String.valueOf(lati));
                Log.e("updated", "updated latitude...............");
                mLiveCardView.setTextViewText(R.id.longitude_value,
                    String.valueOf(longi));
                mLiveCardView.setTextViewText(R.id.speed_value,
                        String.valueOf(speed));
                // Always call setViews() to update the live card's RemoteViews.
                mLiveCard.setViews(mLiveCardView);
                // Queue another score update in 30 seconds.
                mHandler.postDelayed(mUpdateLiveCardRunnable, DELAY_MILLIS);
            }
        }

您可以使用类似于Compass sample的方式对此进行建模：

在您的服务中实施IBinder，其中包含更新实时卡的方法。
让您的菜单活动（处理实时卡上的上下文语音命令）绑定到服务并获取对该活页夹的引用。
选择菜单项时调用相应的活页夹方法，要求服务更新实时卡。
