将字符串月份转换为整数java

Convert String month to integer java(将字符串月份转换为整数java)

问题描述

如何将月份字符串转换为整数?

How do I convert a month string to integer?

在点击方法时，我想显示所选日期，但如果日期有事件，它应该显示更多关于该事件的内容.检查假日事件的方法需要整数值.

On click method I want to display the date which is selected but if the date has an event it should display something more about the event. The method to check for the holiday event requires integer values.

代码如下:

更新:

@Override
public void onClick(View view)
    {
        int m = 0;
        int d, y;
        String date_month_year = (String) view.getTag();
        selectedDayMonthYearButton.setText("Selected: " + date_month_year);

        String [] dateAr = date_month_year.split("-");
        Log.d(tag, "Date Split: " + dateAr[0] + " " + dateAr[1] + " " + dateAr[2]);
        y = Integer.parseInt(dateAr[2]);



        try {
            Calendar c1 = Calendar.getInstance();
            c1.setTime(new SimpleDateFormat("MMM").parse(dateAr[1]));
            m = c1.get((Calendar.MONTH) + 1);
        } 
        catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        //int m = Integer.parseInt(dateAr[1]);
        d = Integer.parseInt(dateAr[0]);
        Log.d(tag, "Date forward: " + d + " " + m + " " + y);

        if (isHoliday(d, m, y))
        {
            Intent i = new Intent(view.getContext(), HijriEvents.class);
            i.putExtra("date_string", date_month_year);
            startActivity(i);

        }


        try
            {
                Date parsedDate = dateFormatter.parse(date_month_year);
                Log.d(tag, "Parsed Date: " + parsedDate.toString());

            }
        catch (ParseException e)
            {
                e.printStackTrace();
            }
    }

    public Boolean isHoliday(int d, int m, int y)
    {
        HijriCalendar hijri = new HijriCalendar(y, m, d);
        if (!hijri.checkIfHoliday().contentEquals(""))
            return true;
        return false;
    }

推荐答案

Calendar cal = Calendar.getInstance();
cal.setTime(new SimpleDateFormat("MMM").parse("July"));
int monthInt = cal.get(Calendar.MONTH) + 1;
