Finishing touches

As I said last time, I reckon there are two things left to do before I have a module that is worth testing.

First - I want to notify the user when a date is entered successfully. Now, this is not essential in the grand scheme of things, because when the whole app is complete, closing SSA will lead the user to a screen which shows the date (among other things). Whether or not I decide to retain it then, I want to have it now, just so that I know it's working when I test it!

The easiest way to do that is with what is called Toast - I imagine because when it is ready, it pops up! Toast is a kind of message that appears in a little box floating on the screen for a set duration.
Toast has three key components (or 'arguments', in this instance). The Context, being the current state of the application; the Text, being what you want your Toast to display; and the Duration, being how long to display it for.

As usual with Android's imaginative variable names, we get something like this:

Context context = getApplicationContext();

        CharSequence text = "You are getting married on " + WedDate + "!";

        int duration = Toast.LENGTH_LONG;

        Toast toast = Toast.makeText(context, text, duration);

        toast.show();

As you can see, here we will tell people "You are getting married on []!", for a duration of Toast.LENGTH_LONG. I don't know exactly how long that is, but it's a few seconds; certainly long enough to read this message.

Alright, so on to the second thing I wanted to add - and this is probably entirely temporary: a message on WLA to confirm that the app knows the user's wedding date.
I've put exactly the same Toast, just replacing "You are getting married on " with "Your wedding date is ", so that if I close SSA and get back to WLA at the same time as a Toast appears, I will know which Activity is responsible for it.

In both these cases, I already had the import statement - import android.widget.Toast - otherwise I would have to add it before Eclipse would be happy.

Now, bearing in mind that 1) This is one small corner of the planned app, and 2) That it may not even begin to work when tested - it's time to start testing this thing, and see what breaks!
