Question

美好的一天。我有一个课程，应该在字符串中给我当天的名字，但不是给我当天的名字，而是给我今天前一天的名字。

我一直在检查调试器上发生了什么，显然交换机在当天（当前，它是星期天）工作，并在TextView和ImageView上放置正确的文本和图像。但是一旦调试器完成，显示的图像和文本就是星期六的那些。

这是我的班级：

private void checkWeekday() {

    String week_day;
    Locale loc = new Locale("es","MX");
    SimpleDateFormat day_format = new SimpleDateFormat("EEEE", loc);

    Calendar calendar = Calendar.getInstance();
    week_day = day_format.format(calendar.getTime());
    week_day = week_day.toLowerCase();

    switch (week_day) {
        case "domingo":
            textView_weekday_name.setText(sunday);
            imageView_diets_weekday.setImageDrawable(drawable_sunday);
        case "lunes":
            textView_weekday_name.setText(monday);
            imageView_diets_weekday.setImageDrawable(drawable_monday);
        case "marter":
            textView_weekday_name.setText(tuesday);
            imageView_diets_weekday.setImageDrawable(drawable_tuesday);
        case "miércoles":
            textView_weekday_name.setText(wednesday);
            imageView_diets_weekday.setImageDrawable(drawable_wednesday);
        case "jueves":
            textView_weekday_name.setText(thursday);
            imageView_diets_weekday.setImageDrawable(drawable_thursday);
        case "viernes":
            textView_weekday_name.setText(friday);
            imageView_diets_weekday.setImageDrawable(drawable_friday);
        case "sábado":
            textView_weekday_name.setText(saturday);
            imageView_diets_weekday.setImageDrawable(drawable_saturday);
    }

}

需要注意的事项：此方法是在片段内的@AfterViews方法上调用的。

我已经尝试将日历位用于我的主@AfterViews方法，但它仍然获得前一天的名称。

我怀疑我正试图将这一天的名字写在错误的地方，但无论我把它放在哪里，它仍会在星期六给我。

作为参考，这是我的@AfterViews方法的外观：

@AfterViews
protected void init() {

    checkWeekday();

    boolean logged = Prefs.getBoolean(user_logged, false);
    boolean subbed = Prefs.getBoolean(user_subscribed, false);
    String email = Prefs.getString(user_mail, "");

    mixpanel = MixpanelAPI.getInstance(getContext(), mixpanel_token);

    setHasOptionsMenu(true);

    if (logged && subbed) {

        List<UserMeals> meals = new RushSearch().find(UserMeals.class);

        if(meals.size() != 0) {

            setDataFromLocal();
            onClickHandler();

        } else {

            try {
                checkIfNewPlan(email, "fetch");
            } catch (JSONException e) {
                e.printStackTrace();
            }
            onClickHandler();
        }
    } else {
        emptyLayout("nosub");
    }

}

感谢。

修改

我在交换机的每个案例中都缺少 break 。对此感到尴尬！非常感谢你！

要使用日历实例获取当前日期，请使用以下方法：

public static String getCurrentDate(){
    final Calendar c = Calendar.getInstance();
    int year = c.get(Calendar.YEAR);
    int month = c.get(Calendar.MONTH);
    int day = c.get(Calendar.DAY_OF_MONTH);

    return (month+1) +"/"+ day + "/" + year;
}

由于日历月是从0开始的，意味着1月实际上是0而不是1，你需要加1！

我刚刚查看了你的switch语句，它在case语句中没有中断？

switch (week_day) {
    case "domingo":
        textView_weekday_name.setText(sunday);
        imageView_diets_weekday.setImageDrawable(drawable_sunday);
        break;
    case "lunes":
        textView_weekday_name.setText(monday);
        imageView_diets_weekday.setImageDrawable(drawable_monday);
        break;
    case "marter":
        textView_weekday_name.setText(tuesday);
        imageView_diets_weekday.setImageDrawable(drawable_tuesday);
        break;
    case "miércoles":
        textView_weekday_name.setText(wednesday);
        imageView_diets_weekday.setImageDrawable(drawable_wednesday);
        break;
    case "jueves":
        textView_weekday_name.setText(thursday);
        imageView_diets_weekday.setImageDrawable(drawable_thursday);
        break;
    case "viernes":
        textView_weekday_name.setText(friday);
        imageView_diets_weekday.setImageDrawable(drawable_friday);
        break;
    case "sábado":
        textView_weekday_name.setText(saturday);
        imageView_diets_weekday.setImageDrawable(drawable_saturday);
        break;
}

我感觉这是问题！
