Android : Soft input layout doesn't change as intended

I have a problem with my android soft input layout.

What I need is a phone layout which only accepts numeric values. I have done this before by modifying xml:

android:inputType="phone"
android:digits="0123456789"

and it worked like a charm.

Now the current EditText is generated dynamically, and I have to do it programmatically.

I've already tried

mEditTextET.setInputType(InputType.TYPE_CLASS_PHONE | InputType.TYPE_NUMBER_FLAG_DECIMAL | InputType.TYPE_NUMBER_FLAG_SIGNED);
mEditTextET.setKeyListener(DigitsKeyListener.getInstance("0123456789"));

but it shows text layout instead of phone layout.

Any ideas?
