if input type as number then - sign will not be accepted, so you need to use input type as numberSigned like

android:inputType="numberSigned"

or

android:inputType="text"
android:digits="0123456789-"

inside EditText

If your number is to be decimal you can declare: android:inputType="numberSigned|numberDecimal"

android:inputType="number"

A numeric only field. Corresponds to TYPE_CLASS_NUMBER | TYPE_NUMBER_VARIATION_NORMAL.

use

android:inputType="numberSigned"

Can be combined with number and its other options to allow a signed number. Corresponds to TYPE_CLASS_NUMBER | TYPE_NUMBER_FLAG_SIGNED.
