Adding a Coffee - Saving our data in 'Coffee Check In'

Our Add screen looks as follows:

So, first of all, we need to bind to each of the widgets to 'get at' the new coffee details (possibly like this) - where would be the best place for this code?

 name = (EditText) findViewById(R.id.nameEditText);
 shop = (EditText) findViewById(R.id.shopEditText);

Specifically, the add() method needs to

• Grab all the values that the user has entered for the Coffee details, validate them & create a Coffee object

• Add the Coffee object to our list (coffeeList)

• Launch the "Home" Activity to return to the home screen, to display the current list of Coffee objects (probably via a call to goToActivity())

Without referring to the notes (too much!) try and get this working, but here's some extracts to get you started.

coffeeName = name.getText().toString();
coffeeShop = shop.getText().toString();
    try {
    coffeePrice = Double.parseDouble(price.getText().toString());
    }
    catch(NumberFormatException e){
    coffeePrice = 0.0;
    }
ratingValue = ratingBar.getRating();

and this

Coffee c = new Coffee(coffeeName, coffeeShop, ratingValue, coffeePrice,0); 
coffeeList.add(c);

goToActivity(this,Home.class,null);

Run the App once again to confirm the add feature is now implemented.

However, if you're not seeing your list of coffees (albeit in a very rudimentary list!) you might need to take another look at your Home Activity and try and work out what's missing - but don't worry, it's in the solution.
