Input Type Number, no negative sign or decimals allowed?

I have two edittext views that 开发者_StackOverflowI using for a calculation and both need to be limited to numbers only so I'm using the InputType to do this, but now I cannot enter a negative number or any numbers containing decimals!

Any ideas or solutions?

Thanks!

You should use numberSigned or numberDecimal, or both numberDecimal|numberSigned to enable features you need.

Simply use the below and even the device input keyboard will contain numbers only:

myTextView.setInputType(
  InputType.TYPE_CLASS_NUMBER);
