I want to design simple app widget which has two textview and two button for previous/next. I am getting difficult to handle button click in app widget. Actually my desire is,if user click on previous button i want to show previous value and if user click on Next button i want to show next value from database. How to know which button is clicked? here i register button click listener like this

  public static class UpdateWidgetService extends IntentService {

    public UpdateWidgetService() {
        super("UpdateWidgetService");

    }

    @Override
    protected void onHandleIntent(Intent intent) {
        AppWidgetManager appWidgetManager = AppWidgetManager
                .getInstance(this);

        int incomingAppWidgetId = intent.getIntExtra(EXTRA_APPWIDGET_ID,
                INVALID_APPWIDGET_ID);
        if (incomingAppWidgetId != INVALID_APPWIDGET_ID) {
            updateOneAppWidget(appWidgetManager, incomingAppWidgetId);

        }

    }


    private void updateOneAppWidget(AppWidgetManager appWidgetManager,
            int appWidgetId) {
        DatabaseManager dbManager = new DatabaseManager(this);

        dbManager.open();
        String contactNumber, date, status, message;
        ArrayList<QueuedMessage> listOfQuedMessage =        (ArrayList<QueuedMessage>) dbManager
                .fetchContactNumber();
        if (listOfQuedMessage.size() == 0)
            Log.i("Db", "null");
        else{
        date = dbManager.fetchDate();
        message = dbManager.fetchMessage();
        status = dbManager.fetchStatus();

        dbManager.closeDatabase();

        RemoteViews views = new RemoteViews(this.getPackageName(),
                R.layout.schdulesms_appwidget_layout);
        views.setTextViewText(R.id.to_appwidget_saved_data,
                listOfQuedMessage.get(count).contacNumber);
        views.setTextViewText(R.id.date_appwidget_saved_data, date);
        views.setTextViewText(R.id.status_appwidget_saved, status);
        views.setTextViewText(R.id.message_appwidgset_saved_data, message);

                   if(button1){
               btnNxtClick(views, appWidgetId,listOfQuedMessage.size());

                 btPrevClick(views, appWidgetId, listOfQuedMessage.size());
                    }

        appWidgetManager.updateAppWidget(appWidgetId, views);
        }

    }

    private void btnNxtClick(RemoteViews views, int appWidgetId,int sizeOfList) {
        Intent btnNextIntent = new Intent(this, this.getClass());
        btnNextIntent.putExtra(EXTRA_APPWIDGET_ID, appWidgetId);
        PendingIntent btnNextPendingIntent = PendingIntent.getService(this,
                0, btnNextIntent,    PendingIntent.FLAG_UPDATE_CURRENT);
        views.setOnClickPendingIntent(R.id.btnNext, btnNextPendingIntent);

    private void btPrevClick(RemoteViews views, int appWidgetId,int sizeOfList) {
        Intent btnNextIntent = new Intent(this, this.getClass());
