Question

我的小部件包含一些文本视图和一个按钮。按下按钮会调用填充文本视图的Web服务。

这样可以正常工作，但按钮只执行一次，然后在第一次按下后不执行任何操作。 logcat中没有错误。

我删除了webservice方法，使其更易于阅读。下面的代码仍然显示相同的问题：按下按钮仅触发一次。

有人能帮忙吗？

编辑：我认为问题可能是我没有广播接收器？

    @Override

    static void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
            int appWidgetId) {

        RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.dashboard_widget);
        cont = context;
        appWidgMan = appWidgetManager;
        appWidgID = appWidgetId;
        count = count + "a";
        views.setTextViewText(R.id.txvWidgetSales, count);

        Calendar cal = Calendar.getInstance();
        SimpleDateFormat format = new SimpleDateFormat("d MMM yyyy 'at' h:mm:ss a");
        views.setTextViewText(R.id.txvWidgetDate, format.format(cal.getTime()));

        appWidgetManager.updateAppWidget(appWidgetId, views);
    }
}

Android Widget Button仅触发一次
