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

问题描述

我有一个由数据库中获取的数据填充的数组字符串.现在对于数组的每一行，我想在日历中添加一天，今天的0"行，明天的1"行，明天之后的2"行等......我创建了这段代码来控制数组中每个元素的位置，但是我如何添加天数?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

您可以只获取以毫秒为单位的时间，然后添加一天的毫秒数.

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);           
        }
