Configure android EditText to allow decimals and n

Question

I have an Android EditText that I want to have the number keyboard come up.

If I set the android:inputType to numberSigned, I get the number keyboard and the ability to type in negatives. However this won't let me use decimals. If I use the numberDecimal inputType I can use decimals but not negatives.

How do you get the number keyboard with the ability to type in decimals and negatives?

Answer 1

We can use,

edit_text.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_SIGNED);

if we need to use programmatically..

Answer 2

You are just missing this in your EditText,

android:inputType="numberDecimal|numberSigned"

Answer 3

Some phones have the decimal and negative in the same button and makes it unable to do negatives. I figured out a way you could separate the buttons by simply adding-

android:inputType="numberDecimal|numberSigned|textPersonName"

android:digits="0123456789-."

That way you still have the number keyboard layout but the negative and decimal buttons will be separate and you cannot use any other digit that messes up the app.
