问题
I am trying to create a Dashed input field for numbers in android layout, such as " _ _ _ _ " where I can add 4 numbers and get them in my main activity. I have searched a lot but not getting any better solution.

Use this library to achieve your objective. https://github.com/glomadrian/material-code-input
回答2:
Create EditText for 4 dashes and implement OnTextChanged() for every EditText to quickly jump to other input. Make sure the EditText has input type as number and can only allow a single digit. You can create such with this concept.
