Android : Spinner Calculator

I am trying to make a calculator based on the calorie options associated with a food type Spinner (calories stored in array and food class). However it isn't working, any idea what is wrong with this code?

            public void onClick(View v, Food cl) {
            Spinner spr = (Spinner) findViewById(R.id.planspinner);
            EditText editText6 = (EditText) findViewById(R.id.editText6);
            TextView textView8 = (TextView) findViewById(R.id.textView8);

            String selectedItem = (String) spr.getSelectedItem();

            if (selectedItem.trim().equals("*")){
                float result = Float.parseFloat(editText6.getText().toString())) * Float.parseFloat(String.valueOf(cl.getCalories()));
                textView8.setText(Float.toString(result));
            }

            Button button4 = (Button) findViewById(R.id.button4);

            button4.setOnClickListener(listener);
        }
