        bitmap.compress(Bitmap.CompressFormat.JPEG, 20, byteArrayOutputStream);
        byte[] imageType = byteArrayOutputStream.toByteArray();
        return Base64.encodeToString(imageType, Base64.DEFAULT);
    }
}

What I have tried:

- Hari (EditText) = showing 2 days later (example)
- edittext (EditText) = Choosing a date

Solution 1

Start with a Calendar | Android Developers[^] object. You can then use the add method to increment the day. An added benefit is that it will automatically handle any dates going beyond the end of the month or year.

Thanks a lot sir.
but... i still don't know how to use loop when post...

Richard MacCutchan 21-Oct-20 4:07am

Sorry, but I do not understand what you mean by "use loop when post".

Komang Putra 21-Oct-20 4:23am

uh.. just like this...
i post 'a' on my data on today (21 October 2020), but i choose 3 days after today..
so the output is :

data date
a 21 October 2020
a 22 October 2020
a 23 October 2020

just like that...
in data keep same but in date is different..

Richard MacCutchan 21-Oct-20 4:53am

So create a Calendar object with today's date. Start a loop for the number of days you wish to post, e.g. from 0 to 3, and do something like:

Calendar myCal = Calendar.getInstance(); // new calendar with today's date
for (int day = 0; day < 3; ++day) {
    myCal.add(Calendar.DAY_OF_MONTH, day);
    // post the details
}
