下周在android中实现

问题描述

在我的示例项目中，我必须在下周周一至周日在文本视图中实施(如 5 月 6 日 >> 12 My).单击下一个按钮时，它必须显示下周的开始日期和结束日期(如 5 月 13 日 >> 5 月 19 日).我已经使用以下代码实现了初始周视图

In my sample project i have to implement next week Monday to sunday in a text view (like 6 May >> 12 My). on click of next button it must show next week start date and end date (like 13 May >> 19 May). I have implemented the intial week view with the following code

   Calendar c = Calendar.getInstance();
    c.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);
    SimpleDateFormat df = new SimpleDateFormat("dd MMMM");
    String printDate = df.format(c.getTime());
    //gestureEvent.setText(reportDate);
    c.add(Calendar.DAY_OF_WEEK, 6);
    String printDate2 = df2.format(c.getTime());
    gestureEvent.setText(reportDate +" >> "+reportDate2);

点击下周按钮我已经这样做了，但它是静态的，这只是一次尝试:)

on click of next week button i have done this but it static it was just an attempt attempt :)

onclick 会调用这个函数 goNextWeek()

onclick will call this function goNextWeek()

public void goNextWeek()
{

    Calendar c = Calendar.getInstance();
    c.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);

        c.add(Calendar.DAY_OF_WEEK, 6);
        System.out.println("End Date : " + c.getTime());

        SimpleDateFormat df = new SimpleDateFormat("dd MMMM");
        String reportDate = df.format(c.getTime());
        gestureEvent.setText(reportDate);
        c.add(Calendar.DAY_OF_WEEK, dates);
        c.add(Calendar.DAY_OF_WEEK, 1);
        System.out.println("End Date asdfadf: " + c.getTime()); 


}

请告诉我如何显示下周的开始和结束日期?

please tell me how to show next week start and end date?

推荐答案

这是您的解决方案.

Calendar mCalendar = new GregorianCalendar(); 
        mCalendar.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);
        SimpleDateFormat mDF = new SimpleDateFormat("dd MMMM");
        String printDate = mDF.format(mCalendar.getTime());
        mCalendar.add(Calendar.DAY_OF_MONTH, 6);
        String printDate2 = mDF.format(mCalendar.getTime());

        System.out.println(printDate + " >> " + printDate2);
        gestureEvent.setText(printDate + " >> " + printDate2);

按钮实施更新

写一个方法，将weekNumber作为参数..

Write a method, which will take weekNumber as params..

private static String getNextWeek(int weekFromToday) {
        Calendar mCalendar = new GregorianCalendar(); 
        mCalendar.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);
        mCalendar.set(Calendar.WEEK_OF_YEAR, 
                mCalendar.get(Calendar.WEEK_OF_YEAR) + weekFromToday);          

        SimpleDateFormat mDF = new SimpleDateFormat("dd MMMM");
        String printDate = mDF.format(mCalendar.getTime());
        System.out.println(printDate);

        //gestureEvent.setText(reportDate);
        mCalendar.add(Calendar.DAY_OF_MONTH, 6);
        String printDate2 = mDF.format(mCalendar.getTime());
        System.out.println(printDate + " >> " + printDate2);
        return printDate + " >> " + printDate2;        
    }

现在声明一个静态文件为

Now declaire a static filed as

private static int weekNumber = -1; 

并在按钮单击时编写以下代码

and write below code on button click

weekNumber = weekNumber + 1;
gestureEvent.setText(getNextWeek(weekNumber));

这会起作用.

编码愉快 :)
