Java – EditText Enter the amount

I’m working on a point of sale app.

So I want to let the user enter the purchase amount

1. Let’s say the user enters 100000, but I want it to automatically display 100,000. 1000000 becomes 1,000,000

2. The second problem is that I don’t want users to be able to enter on their own.

3. The third problem is that because this is money, we can’t let users enter 0 in the first place.

Any ideas?

So far, I’ve only been able to come up with inputType=numberDecimal which isn’t very helpful.

Thank you very much

P.S.: I don’t need any decimal places

If you want

to use it in currency, add addTextChangedListener to the edittext you want and then watch for the change and reformat it, here’s the sample code

private String current = "";
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
    if(!s.toString().equals(current)){
       [your_edittext].removeTextChangedListener(this);

String cleanString = s.toString().replaceAll("[$,.]", "");

double parsed = Double.parseDouble(cleanString);
       String formatted = NumberFormat.getCurrencyInstance().format((parsed/100));

current = formatted;
       [your_edittext].setText(formatted);
       [your_edittext].setSelection(formatted.length());

[your_edittext].addTextChangedListener(this);
    }
}
