如何根据日期和时间从资源文件夹中读取文本文件时间 [英] How to read text files from assets folder according to date & time

问题描述

我正在开发一个激励应用程序，每天都有不同的words.txt / texts.txt文件，即365个文件。

i已将每个.txt文件存储在我项目的资源文件夹中并将其引用到出现在textview中。我希望用户每天阅读不同的文件/主题：



a。我想以一种方式开发应用程序，使得当天的每个消息（文本文件）将在启动屏幕后自动显示给用户，而无需用户具有

导航到当天的消息。



但是当我运行应用程序时它显示空白



请参阅下面的代码

I am developing a motivational app that has different words.txt/texts.txt files for each day i.e 365 files.
i have stored every .txt files in my project's assets folder and refference it to appear in a textview. which i will like users to read different files/topics per day:

a. I will like to to develop the app in a way that each message(text file) of the day will
be shown to the user automatically after the splash screen, without the user having
to navigate to the message of the day.

But when i run the app it shows blank

see my code below
