How do I use InputType=numberDecimal with the “phone” soft keypad?

Question

For an EditText box, the user should only be entering valid numbers, so I am using android:inputType=\"numberDecimal\". Unfortunately, the soft keyboar

So far, what I've decided to do is extend the DigitsKeyListener and override getInputType() so that it will return InputType.TYPE_CLASS_PHONE. This allows me to use the handy filter() in DigitsKeyListener, but at the same time use the TYPE_CLASS_PHONE soft keyboard. I'm new to Android programming, but this appears to work without breaking anything. Code is something like this:

import android.text.method.DigitsKeyListener;
import android.text.InputType;
public class CustomDigitsKeyListener extends DigitsKeyListener
{
    public CustomDigitsKeyListener() {
        super(false, false);
    }

    public CustomDigitsKeyListener(boolean sign, boolean decimal) {
        super(sign, decimal);
    }

    public int getInputType() {
        return InputType.TYPE_CLASS_PHONE;
    }
}

Is there anything wrong in doing this (switching the return of getInputType() to something that the superclass didn't intend)?
