Android日历添加日 [英] Android Calendar add day

问题描述

我有一个数组String，该数组由从数据库中获取的数据填充. 现在，对于数组的每一行，我想向日历添加一天，今天的行"0"，明天的行"1"，明天的行"2"，等等. 我创建了这段代码来控制数组中每个元素的位置，但是如何添加天数呢? 谢谢

I have an array String populated by data taken from the database. Now for each row of the array I want to add a day to the calendar, the line "0" day today, the line "1" tomorrow, the line "2" after tomorrow etc .. I created this code that controls the position of each element of the array, but how I add the days? thanks

Calendar prova = Calendar.getInstance();
        int size = id_op.length;
        for(int i = 0; i< size; i++){                 

        }

推荐答案

您可以以毫秒为单位获取时间，然后在其中添加一天的时间.

You can just get the time in milliseconds and then add a day worth of milliseconds to it.

Calendar prova = Calendar.getInstance();
        int size = id_op.length;
        for(int i = 0; i< size; i++){                 
            Long time = prova.getTimeInMillis();
            time = time + 86400000;
            prova.setTimeInMillis(time);           
        }
