Currency format for EditText

Question

I am using this library to format the text as user is typing. I have an EditText where user types in money. I want to achieve the following behavior as user types:

User input -> Result in EditText

1 -> 1 dollars

10 -> 10 dollars

100 -> 100 dollars

1000 -> 1 000 dollars

However, what I got is that:

1 -> 1 dollars

10 -> 10 dollars

100 -> 100 dollars

1000 -> 100 0 dollars

  val mask = MaskedTextChangedListener(
            "[000] [000] [000] dollars",
            false,
            etAmount,
            object : TextWatcher {
                override fun afterTextChanged(s: Editable?) { }

                override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {}

                override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {}
            },
            null
        )

 etAmount.addTextChangedListener(mask)

The documentation is not very clear on how to achieve this and I am stuck on this issue. Any suggestions would be greatly appreciated.

Library author here.

We've got a wiki page describing masks for texts with right-to-left alignment; this page includes a case similar to yours.

In short, try configuring your listener like this:

mask.rightToLeft = true
