Shortcut for assigning method parameter to a field in Android Studio

Question

In Eclipse when I press Ctrl + 1 on a method parameter it gives me an option to assign that parameter to a field of the same type.

In following example, after pressing Ctrl + 1 Eclipse would suggest assigning methodParameter to the mClassField.

private class Aclass {

    private RandomType mClassField;

    public Aclass(RandomType methodParameter){
    }
}

Is there a shortcut for this in Android Studio, please?

There is only an option to Create Field for Parameter 'xxx' after pressing Alt + Enter which is not what I want. I'd like to assign the parameter to an existing field.

This only works in Android Studio as long as the method parameter and the field have the same (or close enough) names.

In the mentioned example Alt + Enter would suggest assigning the parameter to the field only if the name of the field was mMethodParameter (or the name of the parameter was classField) as shown here:

private class Aclass {

    private RandomType mClassField;

    public Aclass(RandomType classField){
    }
}

Alt + Enter would indeed offer to generate following:

private class Aclass {

    private RandomType mClassField;

    public Aclass(RandomType classField){
        mClassField = classField; // generated code
    }
}

Eclipse works a bit better in the way that it considers types too (not only names) when giving you this option.

EDIT: Some other useful shortcuts you can use for automatic assignment:

Cmd + Alt + V to convert selected expression to a variable
Cmd + Alt + F to convert selected expression to a field
Cmd + Alt + C to convert selected expression to a constant
