How to mask EditText to take input in specific format

Question

I'm trying to restrict what my EditText takes as input. I want it to take a maximum of 21 million (20,999,999.99999999). Is it possible to achieve> if, then how do I go about it? I've tried using InputFilter with a pattern [0-9]{0,9}+((\.[0-9]{0,7})?)||(\.)?. Show me how to do it.

Answer 1

Well, I read Francesco's answer and your comment also. If you need to check the decimal point, you can try this below.

EditText someText = findViewById(R.id.someValueInputHi);
String paw = someText.getText().toString().replaceAll("\\s+", ""); //rem unusual spaces
Double someInput = Double.parseDouble(paw);
if (someInput < 5.3465726543d | someInput > 3.7834657836d) {
    //Ok now
} else {
    //Oops, no man
}

You only take the value between 5.3465726543 and 3.7834657836.

Why double?

As the name implies, a double has 2x the precision of float. In general, a double has 15 decimal digits of precision, while float has 7.
