How do I restrict my EditText input to numerical (possibly decimal and signed) input?
Solution 1:
There's no reason to use setRawInputType(), just use setInputType(). However, you have to combine the class and flags with the OR operator:
edit.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL | InputType.TYPE_NUMBER_FLAG_SIGNED);
Solution 2:
Try using TextView.setRawInputType() it corresponds to the android:inputType attribute.
