you are passing this in the following piece of code,

 ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                    android.R.layout.simple_spinner_item,list);

Not sure in which block this code lies or which class, but ensure that this refers to ActivityName.class or the context
