Android : how to create a Object using Reflection and pass constructor parameter?

I'm trying a button using reflection in android, by the following code

 public String createView(String classFullName){
        try{
            Class clazz = Class.forName(classFullName);

            Object obj = clazz.newInstance(); // but I need to pass the Context using this;


        }
        catch(ClassNotFoundException ex){
            return null;
        }
    }

but the main problem, is how to pass Context ( which is this in my case ) to the Object since they all should be a View.
