How do you set the EditText keyboard to only consist of numbers on Android?

Question

I want my EditText to display a keyboard that ONLY has numbers visible, no other characters.

I have tested with all available inputs and it doesn't work. I searched for a way to get a keyboard that only has numbers but I have only seen references to:

android: inputType = "numberPassword"

But I want the numbers to be visible, like this: (numberPassword)

I have tried with:

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

and

android:inputType="number"

but it appears like this:

After several tries, I got it! I'm setting the keyboard values programmatically like this:

myEditText.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_PASSWORD);

Or if you want you can edit the XML like so:

android:inputType="numberPassword"

Both configs will display password bullets, so we need to create a custom ClickableSpan class:

private class NumericKeyBoardTransformationMethod extends PasswordTransformationMethod {
    @Override
    public CharSequence getTransformation(CharSequence source, View view) {
        return source;
    }
}

Finally we need to implement it on the EditText in order to display the characters typed.

myEditText.setTransformationMethod(new NumericKeyBoardTransformationMethod());

This is how my keyboard looks like now:
